Amazing service! We had McCullough out to do an energy audit in August, and we were lucky we did. Alex Stevens came out and reviewed our current system (old) and said we were lucky it had lasted this long (inherited from previous owner and it may have been 14 years old or older). Rather than push a sale on us, he said we could wait and see until it went out rather than replacing it right away, hoping it might last another year or two. We decided to wait. Then, late Friday of Labor Day weekend it went out! I called Alex and he was able to get a crew of guys out to our house with a whole new ac system on Tuesday after Labor Day. Amazing turn around considering it usually takes longer than that to order the equipment. We were back to comfort that same day. They later came back to make sure our house was air tight to meet the energy audit requirements which really improved the seal on our whole house. Really grateful for their excellent service and quality work!

We have been customers of McCullough Heating & Air for years and had our semiannual service today. Mitchell was courteous and professional. He called ahead of his arrival, arrived when he said he would, and explained everything he had to do. We are very happy with the service from McCullough.

In the late Spring I contracted McCullough HVAC to install a new unit in our upstairs. The entire process was exceptional, seamless and we were totally pleased with the the new unit. Recently encountered a thermostat issue and I called McCullough for assistance. They promptly schedule a service call. Herman arrived on time, preceded by a phone call to confirm his arrival. He quickly diagnosed the problem, explained it to me with clarity and went about the process of resolving it. Could not have been more pleased with his professionalism, skills and the total service call visit. Thank you McCullough.

I will keep this simple, McCullough A/C, and their technician Desmond, were outstanding. My previous A/C company had completely screwed up my unit. Desmond came in with his knowledge of Carrier air conditioners and got me up and running in no time. He was knowledgeable and very professional, He knew his business. Thank you for a good job McCullough. I highly recommend you to others.

Got my annual heating maintenance service done today. Mitchell was professional, courteous, and appreciated he placed shoe covers on his work shoes when he entered my house.

The guys who came out were very knowledgeable and able to answer my questions about the work that had to be done to accomplish the end result to get the new ac unit up and running. It was quite a process and I heard no complaints about the really hot temperature in the attic. They really enjoy their job

Joey was a life saver! Diagnosed and fixed the problem with my heating unit the same day. Excellent explanation of what the problem was and made sure the issue was resolved. 10/10 will use again.

Cody & Mike just left after a flawless AC replacement. The process was easy, friendly, and professional from front to back. McCullough kept me in the loop throughout; I am one happy (cool) customer.But seriously Mike & Cody saved the day. Thanks guys!

We accepted an offer for our house yesterday evening. We found out that the buyer’s inspector will perform the house inspection tomorrow! I called McCullough this morning to ask how to change the filter in our new A/C System (very dusty after some pre-sale construction). Lakia put me on hold for a minute or two, returning to say that she had squeezed us into their schedule and would send a tech over TODAY to do a complete pre-Winter service - and install the new filter!Can anyone beat that for same day service! We will impress upon the new owners that they need not look further for an A/C service provider. I am very grateful for a tip top (and not simple) installation in March this year and for the first class service provided by Mitchell at McCullough today.

They came and provided same day service. It was extra fees but not unreasonable. Im impressed they had warranty parts available for an emergency call

Straight forward company. Installed 2 new a/c units. Took a few trips to complete, but followed through promptly. Competitive pricing too.

Excellent service. I highly recommend the maintenance program.

Mitchell (service person) was great! Helped quickly, friendly, informative and educational and he called in advance. The front desk/scheduling folks were not as great with customer care. McCullough has not yet figured out how to narrow service call times down from 9 hours like any other service/repair company until the day of if you call and ask. I was told by the front desk my account would be noted with a morning visit request twice, yet was actually scheduled for 12-5 that day and it sounded like the first time I called to check, that note was not there and re-entered.

Shelton came out at night, after hours when we needed him the most. He fixed our issue quickly, and got our system back up and running. We are so appreciative of his knowledge and advice, and will definitely remain loyal customers of McCullough!

Called around noon to see if they could check the newly installed ac’s functionality. It wasn’t cooling as expected. They had someone out by 4:30 the same day, who quickly diagnosed a dirty filter due to remodeling construction and replaced the filter for a very reasonable price. I am a very happy customer!

Wonderful experience. Met first with Alex review problems with faulty A/C. Got a clear picture of the problems, then discussed pros and cons of repair or replacement with the Carrier units. We replaced with the Carrier and could not be happier. The installation process was smooth and efficient to say the least—-especially since some unforeseen issues arose with old ducting in some locations in the attic. Mike and Cody were the install team and went way beyond expectations. They worked their butts off in some really challenging conditions in the attic spaces. The Carrier units are quiet and efficient—don’t need to look elsewhere in my opinion==and I did a ton of research prior to calling McCullough, too. Best of all, Mike and Cody took the time to answer the questions posed by my wife and. We got clear, concise explanations which filled in areas that we hadn’t researched or were confused by our research. Use McCullough—you will be glad you did!!

This is the third time using McCullough and we are always happy with their service. It is easy to schedule, theyre able to come out when you need them, and they are efficient when they arrive.

This was my First time using McCullough. I am hugely impressed with their response, their price and their professionalism. I will definitely be using them in the future.

Kyle was great, super fast and incredibly knowledgeable. He is a convincing reminder that when it comes to AC repair, it’s best to call the professionals rather than google. Great service! Cannot recommend enough!

Excellent service. Tech was friendly and got it done quickly. He told me what he had done, gave me a few tips for keeping my system running smoothly, and moved on. I don’t really know what more you can expect. Friendly and timely service seems to be the key for me and they provided both.

Our AC failed and we decided we wanted to replace both the indoor and outdoor units. However, our indoor unit is in a very hard to access attic. One company refused to bid on it. The McCullough team disassembled the unit and reinstalled it in the space, piece by piece.This system is so much better than our old system. We would go through freeze/sweat cycles because the old unit would blow so strongly. The new one blows almost continuously on hot days, but its much gentler and keeps the temperature very stable.The outdoor unit is also amazingly quiet. Its hard to hear a few feet away when its running.We are very pleased with McCullough.

Shelton was fast, efficient, knowledgeable m, and friendly. Perfect. Highly recommended..Gary

We’ve used this company 3 separate times for multiple HVAC related repairs. They have been reliable, responsible, and knowledgeable every single time. When our AC broke over Labor Day weekend on Saturday at 7PM they were at the house doing the repair by 9PM. This company ROCKS! 10/10 recommend. EJ was very friendly.

Great Customer Service! Very professional and responsive! Even on a holiday weekend! EJ was my technician and he was so professional and cared about getting my AC maintenance issue resolved. He let me know where I was on his schedule, he was happy to answer any questions I had. If I could give him a 10 STAR RATING, I would... he deserves one! Thanks for taking care of us during the Fourth of July weekend.

We called them because our upstairs unit stopped working. Before they came I was able to find the problem and solved it (it was a clogged water drain) but I maintained the appointment to have a general check of the system in case there were other problem.The technician was very knowledgeable and easy to work with.The reason I am rating the service as 3 is the value of the inspection vs the cost. I though it was expensive considering it was a report and no actual repair was done. The cost of inspecting 2 units is also doble which I dont understand being only 1 visit.

AC went out on Father’s Day thankful Kyle was able to fix our AC issue so quickly. He had The part needed in his van and was able to get the job done in under an hour. Thank you Kyle for your great conversation as well as your expertise in solving our problems so quickly and having the part on hand. Knowledgeable and fast service.

Derek (Bull) and Desmond are very reliable and patient, hardworking people. They went above and beyond to resolve my issue with my AC. Very hard working evnthough it was late at night they both accomodate and made sure that I am comfortable with my new AC installed. Thank you very much !

Shelton was a great tech and very friendly. He responded very quickly for an after hours call and we couldn’t be more great full for his service! We highly recommend this company and will definitely be using them again (hopefully not soon😁)

I purchased a new HVAC system this spring and today had a problem with the system. Herman came promptly and determined the problem with the thermostat and resolved the issue. I really appreciated his prompt response and efficient resolution of the problem.

Fair Price and excellent post installation inspection. Tech guy came to house to insure that the system was installed correctly, all setting were correct and spend time explaining the Thermostat with its may features.

Kyle came on a Sunday evening and diagnosed the problem. Thursday he installed new parts and we had good AC for the first time in a month. We were totally satisfied with the service and will definitely call McCullough the next time we need help.

Both of our units stopped blowing cool/cold air last week unexpectedly (in Texas there is never a good time of year for this to happen!) so we called McCullough. We were beyond grateful that they were able to have technician out that same afternoon. Herman, our technician, was wonderful! Great communication and was able to thoroughly explain what was happening with our units and discuss our options for repair. He had our units fixed in just two short visits! In less than 36 hours we were back up and running just in time for the summer temps. Customer service was excellent and very helpful, too! Thanks to the crew for helping us keep our cool!!

I’m lucky I chose this company, and I am very grateful they sent Desmond. He repaired a problem by an earlier technician and got my AC back up and running with minutes. Then he was ikind enough to explain the configuration of my current system, and lent his expertise to break down the problem in a wayI could understand it.Great job all around.

McCullough Heating and Air Conditioning installed my Carrier HVAC unit several years ago. I have been very pleased with their service and system’s operation. When I was evaluating different Austin area companies,, I learned from McCullough that besides buying a quality HVAC unit, is also important to choose a reputable company that can expertly install/maintain the unit. That’s McCullough! My unit works well year around. I also use this co. for spring & fall check-ups. Awesome! Affordable too. 👍

My heating and AC system went out right as the February ice storm hit. The McCullough rep came out immediately as the storm was blowing in. He thoroughly went through my options and immediately ordered my chosen unit. Unfortunately, there was no way it could be installed until a week or so later due to weather conditions. After the installation, the Quality Control Manager came out to inspect and found a couple of tweaks that needed to be made, which were taken care of immediately. My new unit works like a dream. The whole process was so easy and hassle free.

I would like to first start by complimenting our technician Elvin. He was kind, friendly, knowledgeable, and took time out to answer all of our questions. McCullough from our first interaction with them exhibited excellent customer service. It is obvious Elvin is only an extension of the company’s mission statement. We look forward to growing a relationship with this company for years to come. If any one is in need of top notch AC/heating repair or service let McCullough Heating & Air be your first and only choice.

Scheduling was spot on. Repair costs and warranty were very clear. EJ was on time a great tech. Pro-style and responsive. Al and team are lucky to have such a great employee. Thanks McCullough!

I had a great experience with McCullough. It was easy to make an appointment and my technician, Kyle, was able to fix my problem in about 30 min. Very easy process!

Mitchell is very professional and easy to work with. He answered any questions I might have had and offered additional services/recommendations as necessary. Mitchell was upfront with additional pricing beyond the maintenance cost, but due to a misunderstanding on my part I interpreted the price as total price and not additional. McCulloch Heating and Air along with Mitchell was able to work with me on this discrepancy; which I appreciated very much.Despite the service window being 8 AM to 5 PM I did appreciate the 30 minute call out before arriving. This gave me time to make sure I was home and ready for the service.I will recommend McCullough to others for their Heating and AC needs.

Very happy with the work that McCullough did on the house ( new ac unit, new ducting, sealing, home performance). My only reason for knocking off one star was that I felt that the there was definitely room to improve when communicating issues from from the initial inspection, what a service is, to the new purchase of the system, to installers, and inspection. I had to make my own list and ensure that those things were covered.

I will only use McCullough in the future. They provided excellent service across the board. Alex and EJ were very attentive and thorough. Highly recommend!

Great job. Tech was friendly, knowledgeable explained what options we had with price, which is always helpful. Weve used McCullough for 18 yrs never disappoint us. The techs also very friendly and knowledgeable. Didnt even take a lunch break till the job was done. After install they came out and did a check up on system. Excellent job all around

We had a new AC/heating unit installed along with additional attic insulation and a comprehensive air infiltration treatment. The team from McCullough was hardworking and personable and answered our questions -- though some work remains to be performed during the quality control process for which weve been given a date two weeks from now. We are currently waiting on a new intake grill, replacement of two vent covers of an unusual size that were damaged and bent during installation, installation of a vent cover which was left but not installed, sealing air leaks under our sinks, and repair of a thirty inch crack in our ceiling after one of the installers lost his balance and landed on the sheetrock. So far the AC unit works very well and we are pleased with the process and hope that the remaining work will be completed during quality control or sometime soon. --Dennis Dillon

So Mitchel was friendly and respectful but charge me for AC tune up $69 which is was good price. Then He charged me $282 to replace a capacitor on the outside unit, which took him maybe 10 minutes to do and did not even give me credit for the tune up toward the AC repair. It customer friendly to me. I will not use McCullough again.

Diagnosed and repaired outside a/c unit. Faulty capacitor caused unit not to function. It took the repairman 15 minutes to diagnose and repair the unit.

Great experience from a professional team, from sales to install and everywhere in between a simple and seamless process to select, purchase and install a new system. Their prices were comparable if not better than the other companies I reviewed and I believe my Carrier system is a better product than the other offers I received. I also appreciated the care and attention to make sure all of the aspects of our system were considered and corrected where necessary and I wasn’t nickel and dimed like I had been with other providers. Definitely recommend and will be using McCullough going forward.

The folks at McCullough are great. Mitchell is our regular service technician and we really appreciate all he does. Hes a great guy and an awesome technician. Thanks!

Excellent & responsive service. They will be my new Air-Con service.

You was highly recommended by my church St. Stephens MBC.The young man Mitchell came out and was very professional and knowledgeable. If wasn’t for him explaining everything I may have waited after he told me the price. I felt he was very competent doing his job. He was very nice. He did an excellent job. I will share your company name due to the wonderful and efficient work he did. Thank you, Loretta Ford

RUN AWAY!I had a great experience in 2014 and decided to trust them again when I moved back to Austin now.Just spent a good amount of money with them, but the main problem is not solved. My home can only reach 67F by 5AM.The Condenser is brand new, so I imagine the airhandler was the issue, so I asked McCullough for help to solve the problem.Since they are the specialist, my expectation was to do a full analysis of the problem, however, they took the easiest path and just replaced the unit.After I realized the problem was not solved, I called them several times to come back, here their conclusion.1. Ductwork is badly designed and might have leakage.2. Charge more $450 to do a J Manual Calculation, to them sell me a new unit if needed.3. Austin is too hot, and the unit is performing well.However.1. Leakage test was done and later I found out a big opening closer to the airhandler installed by them. They came to fix it, but they still use the leakage as an excuse.2. Other companies who want to sell the equipment are ready to do the calculation without extra charge. It seems McCullough is taking every opportunity to profit.3. The installation was a mess, the McCullough Installer Mgr. took a lot of trash left by the installer when he came to inspect the equipment.4. How we can have airports and malls in Texas with freezing temperatures during the summer?5. They tried to blame me saying that I pointed to the problem when I called them. (I am sorry, but I am not an HVAC specialist)It has passed 2 weeks since the last visit from the installation mgr and no report or suggestion of fix was provided yet.Paying more doesnt mean quality delivery or customer satisfaction.I give up to work with them.I hope this post helps other people. Good look to everyone else.UPDATE**About McCullough response for this post.1. They only offered one solution, which was replacing the air handle.2. They never indicated or offered a solution for the condenser mentioned on Mc. response.3. After the installation mgr visit, they never provided a solution. Using my ongoing remodeling as excuse is terrible because I was willing to do it now since I have a contractor that could fix the drywall. The person told me would need to talk to the service mgr before making any recommendation and that feedback call never happened.They were probably expecting that I would forget about the problem since the weather has changed.Honestly, replying to a review without giving a call to the customer first is very unprofessional.Friendly advise, hear your customers, admit when you fail and learn from your mistakes.

Called the after hours number and a tech was out within a few hours. He was professional and quick to diagnose the issue then repair. Great experience all around from calling to the completion of the repair!

They were awesome. I would highly recommend you, check themout if you want efficient, responsive, and knowledgeable a/c /heating issues. Hard to beat.

Super professional team and great service from the first call to the quality control follow up. I highly recommend.

The technician that came out was very professional and polite. It certainly was a relief for the technician to come out and check our air conditioner. It’s July 27 and we certainly wanted to make sure our air conditioner was in good condition.

I cant say enough good things about the service. Joel Galvan was my service tech and he diagnosed the issue with my A/C right away (blower motor and board issues on an 11 year old system). He also discovered a couple wiring issues with the system and repaired them. In addition, he checked the compressor and made sure it was functioning properly as well. He was clear about the issues with my A/C and explained the costs to repair it. He also applied several discounts that I qualified for which helped out in the end. He was prompt, friendly and efficient with his time. I am definitely choosing McCullough again for my future needs.

Amazing professionalism and attention to detail, even helped us qualify and apply for all city rebates

MuCullough Team was excellent. I called them on Sunday as my AC was not getting cold. They called back within an hour and the technician ran me through a number of questions and items to check. After going through that process, he agreed that we needed a technician to come out. He was up front of the cost to come out and visit. I told him it could wait till tomorrow. Monday morning their team called me up and put me on the list for that day. They had a text message setup with me for easy communication with McCullough. The Technician came over and checked my system he determined a switch needed replacement. He replaced it and even validated that the part was covered under warranty. He got my AC back producing cold air inside.Overall a great experience with McCullough and will use them again.

Thanks Kyle! Vinny said you would do us right.Free second opinion call revealed that another company had quoted an outrageously high repair estimate! McCullough is getting the job done, at a great price! Keeping us cool!!!! Cool guys: fast, friendly, and skilled.

Called at 10am and had my A/C fixed by 2pm the same day! Couldn’t recommend them more and I’m definitely coming back for any A/C needs in the future.

McCullough installed our state of the art AC/heating unit in 2018. This unit has received yearly maintenance, except for 2020, due to COVID. This computerized system, provides readouts on the thermostat; alerts for replacing filters, routine maintenance due, and any system failure. It shuts down when any inconsistency in performance is detected preventing damage to major parts. There have been two instances of system failure, both under warranty. In each instance, McCullough answered our emergency call to restore AC in a timely manner. Yesterday, I was both relieved and impressed to receive text updates on their technicians arrival time. Herman quickly discovered the problem and restored the AC to running within an hour. McCullough has been consistently professional in scheduling, communication, and charges for maintenance. I am glad we used the same company to instal and maintain our AC/heating system. I highly recommend McCullough for installation and maintenance of a new AC system.

The problem was a mostly clogged AC condensate drain line. There was a trickle of water outside which fooled me but not the tech, Mitchell. He immediately diagnosed the problem. The drain water was backing up and tripping a sensor that caused the AC to turn off. It took less than 30 minutes to resolve the issue and start cooling the house down from 82 degrees!!! Thanks for the great service.

Kyle was polite and helpful answering any questions we had. we needed a small amount of refrigerant added to keep system running at top performance for coming summer. Will plan to use them again next year for annual inspection, Thanks!

Technician was very informative, professional, on time and above all very, very courteous. Explained all about the system and very laudatory about how clean my system was. I want to be on this program on an annual basis because here in Texas - no good blowing AC spells misery. Thank you so much for sending such a knowledgeable and professional technician. All the best.

Great experience. Very happy with the installed AC unit, and all steps from sales through post install.

My Lennox a/c system started leaking after 11 years. Fixing it would have cost $2,500. So, I looked into options for a new one. After researching various brands, I decided to get a new Carrier system. I requested quotes from various dealers in Austin. McCullough Heating & Air was the most responsive showed the greatest interest in gaining the business.I told their sales manager Derek - he goes by Bull - which features are most important to me and he explained all options and recommended the Carrier Infinity system. It is the top-of-the-line Carrier system, the most energy-efficient, it removes the humidity - which was especially important to me - and comes with a 10 years parts and labor warranty. The Carrier Infinity system is highly rated in online reviews.So far, the system has reduced my overall electricity bills by about 15%. The indoor comfort is greatly improved over the old Lennox system because the Carrier Infinity system very effectively removes the humidity and is extremely quiet. It features fully variable speeds with what Carrier calls Greenspeed Intelligence.While the Infinity system is more expensive than traditional single-stage models, Derek gave me a very good price that made choosing the Infinity system a no-brainer and a smart investment in indoor comfort in the Austin summer heat. Rebates on the most energy-efficient a/c systems are also the highest. McCullough Heating & Air had a very professional crew installing the system in about 6 hours.Thank you McCullough Heating & Air for the great service. I will enjoy my new system for many years to come. If you are looking for great service and a great price on a Carrier a/c system give them a call and ask for Derek.

The tech did a great job of installing two Carrier Infinity Air Purifiers to our existing AC systems. The price with installation was great! Thank you for quality work!

My system had just run out of warranty and the motor had died. Herman and Troy were both up front and honest about what needed to happen in order to fix my system. They are true professionals.

German was very professional and thorough. We have a unique situation that hasn’t been encountered before so we are limbo at the moment but would definitely use them for whatever service is required

We have used this company two other times for complete AC and heater installs at other houses. They are professional and do a good job. We have felt their prices were competitive and fair. Their installers take care to keep the area clean with drop cloths and shoe covers. They wear masks and use good Covid precautions. We will continue to use their service.

The technician was very careful to maintain contactless service (at my request) and kept me fully informed of each step of the repair by phone.I was able to submit my credit card information for payment directly to the office so no signature or contact with the technician was required. The very friendly and professional office staff gave me full disclosure of charges and timeline necessary to complete my repair. I got my diagnosis and repair completed the same day I first called in requesting it. The office immediately emailed my itemized receipt within minutes of completion of my repair. I recommend this excellent company and will certainly call them again if I ever need service or upgrade to my equipment.

In your response to my review. this is my home...not a rental. As of today have not received any paperwork at all for being charged $200 per lb for 3 lbs of refrigerant for a unit where there was no leak detected. I do see you are quite masterful at answering bad reviews. Ive been in business 47 years in Austin and Houston and if I ever thought of treating my clients like I was treated this weekend I would run myself out of business for poor performance and taking advantage of the heat in Texas and a single mom . Shame on yall, $689 and no invoice? What are you hiding? Raking in the big bucks and just cant stop yourself?

Shelton is the best and could easily be a trainer for the company. I have been in customer service for 54 years and have no complaints whatsoever.

EJ was prompt, professional and fixed our issue. Great communication. Will definitely use McCullough again!

The service tech was personable ...but being charged $200 per pound for refrigerant with a min of 3 lbs is robbery. Raising their price by $20 to inspect an air handler just as Texas heats up isalso usury imo $689 to inject some refrigerant without establishing that there was a leak is against industry standards as well.

Very pleased with everyone we interacted with at McCullough - from scheduling people to estimator, to installers to QA inspection. Very professional and courteous. We replaced an aged AC/furnace, ductwork, insulation and weatherization of doors, etc. We took quotes from two others and no regrets going with McCullough. Chris did an excellent job explaining options and recommendations - never felt like I was being sold.

It takes a lot for me to post a bad review but this makes me so mad what they did. I used to work for an ac company so I know the procedure. My system is a little low on freon (410a) when you charge a system you have to weigh the bottle afterwards to know exactly how much freon was added. When I called and asked how much they charge per pound i was told we would have to send a tech to come look and tell you how much youd need and how much it would cost. I asked if she was reading a script and she said no no script thats how its done to know how much youll need. This is a bold face lie. This is sadly another company to come to your house under the impression of a repair only to sell you stuff you dont need. If they were honest she would have told me exactly how he the freon is per pound.

We are so happy to get our 20 year old system replaced by McCullough. Several companies gave us estimates and their estimate was the best and had a choice of options. They were able to schedule us quickly and the 2 men who came to do the installation were on time, polite and cleaned up thoroughly when finished. The outside Carrier unit is so quiet and we love the Alexa enabled thermostat. Im so glad we chose McCullough!

I must compliment the technician ‘Joel’! He made the whole experience of getting my air fixed a pleasure. His expert knowledge along with a very friendly and professional attitude was much appreciated. If you call, ask for this technician !!!

Mitchell was the tech today and like Chris who was the tech on previous calls, he was great. He was efficient, professional and explained everything. Good work and thanks.

I have used McCullough on two houses complete AC replacement as well as hiring them to install anew unit at my place of business.I also utilize them for repair and maintenance.Easy to schedule and a good value.

German was very pleasant, professional, and thorough. Really appreciated his attention to detail and pride in his work. Highly recommend.

German did a very good job of inspecting our air conditioner which had experienced a leak of Pruon and had set off a water monitor alarm in the overflow tray. Another ac service company had concluded that the overflow pipe was functioning and that low Pruon had caused our older ac to freeze and then condense water into the overflow tray.That company concluded there was a leak in our system but did not run a leak test. It advised us to replace the ac system due to its age -13 years for the evaporator and 20 years fore condenser and furnace. German for McCullough confirmed that our unit was low on Pruon and inspected the system for leaks and found a leak in the evaporator coil. He laid out the cost of repair and advised me on whether replacement of the evaporator made sense given its age. As McCullough was providing this device as a second opinion, it did not charge us a service call, and because German found our evaporator to be very easy to check for leaks, he waived the usual leak check charge. He explained everything very clearly and I appreciated the waiver if the leak check. A very good service at an excellent price: zero. Can’t beat that!

Really nice to have workers come in that know there business and get it done and it’s done right. Nice job.

Responded quickly. Fixed the problem. Easy to work with. Appreciated professionalism.

They came on the Memorial Day holiday and were friendly and did a great job with my AC.

A long-time Austin company that provides top notch value and service.

Always on time. Great pricing and service. Kyle was fantastic.

I called many AC companies but most companies were too busy during July 4th holiday except Fox and McCullouh AC had technicians can come and check. Fox technicien said he charges $99 for road trip and $1800 for diagnostic issue and $2500 for other fee if I agree? The McCullouh AC came repaired the problem only charges $89 total that I will join their maintenance program for all my properties. It is absolutely worthy of the investment. It is not easy to find honesty and very knowledgeable good AC technicians. I am very grateful for their amazing services!

These guys are really on their game!Derek was super helpful setting everything up throughAE with the rebates/loan and cut me a great deal on a new AC/furnace.He made some great improvements to the existing ductwork and explained how it would make everything run more efficiently.The crew was the best, quick and thorough and worked great together.They clearly take pride in their work.Cant wait to save some money this summer.Highly recommend!

Have used McCullough for years at both my business and residence. Always great service at reasonable price.

Mitchel was very efficient. Took the time to explain everything he did.

Pleasant and easy to work with. Originally scheduled for HVAC maintenance, but in time before appointment was made and day of appointment the unit stopped circulating air. Tech checked and said it needed a new blower. He had it sent overnight and had it replaced the next day. However when he tried to run the unit the compressor wouldnt stay on. He said it kept overheating. Evidently we need a new HVAC unit.Guess the maintenance went well. the form showing the readings he got is Greek to me.Not sure how to rate star-wise. My previous experience with them was excellent. Wouldnt really want to rate until this whole job is completed.

The technician was great, courteous and just downright good. I’m glad to be their customer

Installed a new AC system, the pump and AHU and both were completed on time and very professionally.

EJ was great and we can’t thank y’all enough for fixing our ac on a weekend and a holiday. We will call you for all our HVAC needs!

We have always been satisfied with their service.

Joel was on time and quickly figured out what was wrong with my thermostat. He waited to see if it started cooling before he left. Great employee.

Great service and installation. Very professional and respectful sales and installation crew. Attic looks organized and 100 times better. Explained everything very well. All rooms are heating at a similar temperature finally.

Joel with McCollough was super professional, knowledgeable, worked quickly and turned technical speak into layman’s terms. Got my AC back up and running in no time. Pup friendly too!

Elvin came to install an Aprilaire cabinet into our HVAC and also resealed our ducts that were not properly installed from a different company. Our home is very old and the attic is not an easy space to maneuver; he came in, got the job done, and provided helpful & professional customer service!! Thank you.
