Mitsubishi recommended Quality 1 as a preferred DFW installer, well-trained so I called them up. They came over (no charge), inspected my garage and kitchen for a 2-zone mini-split heat pump (ductless), gave me a quote soon after, ordered the parts and came by. They finished install in a day, came by to test it in the morning. Exceptionally courteous and professional, great attention to detail, above and beyond to have a clean install, and significantly better communication than I get from contractors. These are too complex to set up correctly yourselves imho. Theyre well worth the fair price - quality indeed - yall be good to them.

Its been almost a month after Quality 1 who is a Trane dealer to replace our 20+ year old Trane AC/Heating system that stopped working a couple of months ago. They had done an excellent job to install whole system on time and setup everything. Now we had enjoyed cool air at home during the last hot summer.Great service and quality work, highly recommend this company.

Very professional operation. The person who quoted us the replacement for our old and failing system was courteous and clear about what we would be getting. His pricing was also very competitive. I read the very good reviews that were posted and that convinced me to call them. Once the pricing was agreed to they set the date and time for installation. They were on time, took care to not be messy and finished the installation on time. We were very pleased with every aspect of the whole process. Highly recommend them!

Saeed did a great job servicing our HVAC units. He was on time, very patient and thorough. I would certainly use them again.

These guys are responsive, professional, fair, and thorough. They replaced our old, failing HVAC system with a new Trane system and added a much needed vent to our upstairs. Everything is working great and we couldnt be happier with their service.

I called yesterday afternoon because my AC at my office stopped working. The lady who answered the phone was nice and professional. She scheduled my appointment for this morning. The tech was on time for the appointment. Saad was extremely friendly and professional. This will definitely be my go to for AC service and repair on the future.

Had a great experience!! Same morning service so we barely noticed the heat creeping up in our house. Technician came out quickly and it only took 15-20 minutes for him to get the cool air flowing again!

They did excellent job, professional, very quick install the outside unit with new concrete pad and new cupper line, all the duct work with new furnace and coil in one day, the Trane display is very attractive connected with WiFi allows us to control the unit form the phone. reasonable price I got bunch of quotes from Home Depot and Costco and more this was the best price. Its been 7 months the Heating system and the AC are excellent . All my Heating and AC service is done by them. when you call, they respond fast, come on time, very professional solve the problem within 15 minutes. I know this company since 2008.Highly recommended

Knowledgeable, quick diagnosis and affordable

Zakariya and his team went above and beyond to help with the AC repair on a very short notice. Trusted professional individuals! Highly recommend. Thanks so much Zak!

Excellent service. Repairment sent soon after first call. Good company with which to work.

A wonderful job done by wonderful people! 11/10 would recommend

I normally don’t leave reviews but I felt compelled to do so. I was highly impressed with the service, price and quality control I received. I feel like I got a deal in addition had a great experience with the installation. The installation team was on time, respectful of my property and did a great job cleaning up and hauling away the trash. I was very impressed when a separate technician came and did a thorough quality control on the installation. To top it off I got a follow up call from the owner asking if everything was okay. It has been a while since I received service like this. Quality 1 just earned a customer for life! Thank you Quality 1 for a wonderful experience.

It took a little over a month to get the unit installed because they had difficulty getting some parts. Other than that the installation went smoothly and the technicians were courteous. Thanks Quality 1!

Sed was professional and accommodation. Will definitely ask for him if I need service again.

Zak & Saeed are very cooperative and professional people.Good Service !

Very professional and quick service. Would gladly recommend to anyone.

Super quick to respond and come out to fix our AC!

I got a new HVAC on Saturday. I spent the last several weeks talking to my friend in Florida who owns a large HVAC company, researching brands, comparing warranties, and getting quotes from local dealers. I can say with a high degree of confidence that your best bet is Quality 1 Energy Systems, the official Trane dealer for this area. Incidentally, Trane is the best quality brand in my friend’s opinion. Q1ES sold me a Trane XR16 (16 seer) for $9,260 with 0% financing for 6 years ($8,000 cash price) and has all of the good qualities of the companies below rolled into one. Ask for Zak, the customer service is a cut above.I also got quotes from:- On Time Experts (high quality services and expert staff, highly responsive, grossly overpriced, lack of transparency in pricing, lots of up selling, good financing options, Daikin)- A#1 (highly recommended by two friends, fair & transparent pricing, highly responsive, inferior financing options, offer included low quality duct cleaning for at no additional cost, Daikin)- AC Pros (honest & humble people, highly responsive, highly detailed & transparent quotes, slightly overpriced, good financing options, Trane)

Great job! I consider them to be one of the premier family own HVAC contractors in the Dallas Metroplex!

Excellent service. Great team, good pricing, and communicate very well. Highly recommend.

Very punctual. Took time to diagnose the problem and came up with a solution

Extremely professional and honest. Took the time to explain in detail what the problem was and all my options to correctly rectified the issue.

Q1 was amazing to work with! They helped us get our HVAC system fully replaced with great quality work, great pricing, and amazing customer service. They even warranted their work. I highly recommend Q1 for any HVAC work!!!!

Quality 1 Energy Systems is great! Their back office staff and Field Techs are always friendly and very knowledgeable. I use them for all of my A/C and Heating maintenance and repair needs. Saed with Quality 1 is outstanding. Hes prompt, honest, and thorough with his work! Thank you to ALL at Quality 1 Energy Systems!!

Professional, knowledgeable, patient, responsive to needs and questions, pleasurable to interact with as a customer and building professional. Very clean and tidy installation in tight conditions.

I purchased an older home last year with the intention of updating the 20yr old HVAC system. After the historical Texas cold snap, I decided to pull the trigger on replacement before the 100 degree summer days hit. Basem quickly responded, gathered the necessary information and made a baseline quote for me to compare to the other companies I was checking with. The quote was transparent and competitive, with zero pressure to upsell, so I scheduled a time for him to come out and verify that no additional work would need to be performed and finalize the deal. Throughout the experience, he was extremely responsive to calls and emails and consistently followed-up and put items we discussed into writing via email for future reference. A short time later his crew completed the install quickly and professionally, and even came out on a Sunday! I am pleased with the professionalism of Basem, the install crew, and as a result, Q1ES overall. The new system is humming along great, and should any unforeseen issues arise, Im confident that between the equipment manufacturer (Trane) and installer we will be taken care of.

Quality 1 Energy Systems provides top quality products and services. Work is done efficiently, accurately, and exactly as promised. Assad provides outstanding customer service. We are very happy customers and will definitely use them in the future.

Called in to get my system checked out. I know it was an older unit when buying the house. They came and checked it out and surprisingly they told me my unit was not worth changing right away. Its a but smaller Ton wise for my house but its working for me with no issues so it would be a waste to get a new on now to save a few bucks a year on a more efficient unit. Definitely kept their card and when its time to get a new u lnit I know who to call. Instead of trying to get money out of me they got my respect and future business.

I used Quality 1 Energy Systems many times since 2005. They are very professional, punctual and they are extremely honest. They will never charge for something it was not needed. I had to use another company because I had an emergency and Quality 1Energy were not available to respond quickly, and I immediately realised the huge difference between this good company and anyone else in that industry. I will recommend Quality 1 Energy Systems all the time.

Jose and Semeie arrived on time, diagnosed my AC issues and repaired them promptly and professionally. They wore protective face masks and covers on their shoes which we appreciated. Jose diagnosed the problems with our AC units, discussed repairs and their costs, and got my approval before proceeding. They completed the repairs and maintenance speedily. Excellent service and I highly recommend this company.

I have no hesitation in recommending Q1Im working for Carrier Enterprise as Inside Sales Engineer, This company is truly a pleasure to do business with throughout Plan & Spec projects. All personnel involved were professional, polite and amiable. The stuff are fast, friendly & helpful.Overall,I recommend Q1 for your repair, installation & other services.

Great experience as usual. This is the best HVAC company I have EVER worked with. I used them for both commercial and residential. I recommend them without hesitation.

Always courteous service. Efficient and at the right price.

Yahoo.comQuality 1 Energy Systems is an honest good air conditioning and heating company. I found them originally thru my contractor Stuart Margol Companies. Mohammad worked on my addition to my home in 2013 and I have used them every since. They are the first company I feel is honest and does not come up with things wrong with my air conditioning and heating systems that are not true. When something is wrong they explain it to me, explain the costs and get it fixed in a timely manner. There office staff, Zac is also very professional and responsive. I would highly recommend them to anyone who is looking for a great airconditioning and heating company. They also do my yearly maintenance for me.

Really great service every time we use them. Our go-to company for any A/C-related issues and maintenance.

I found the technician at Quality 1 to be courteous and professional. The work was not only good but good value. The office scheduled the appointment promptly and the technician arrived on time. I would recommend Quality 1 Energy Systems without reservation.Manne Charhon - Mateo Office Park, Frisco

It’s honestly really difficult to find an AC company that you can trust. Rates are so all over the place and it’s impossible to know which one is actually giving you a reasonable deal. Zak and the team really did go above and beyond for my full system install. I’m extremely meticulous and they legitimately covered every base the first time without me having to request it - really impressive. Thanks again guys

The Tech, Was Courteous and Professional. High Quality Service Was Preformed and Maintenance Advice Was Given to Us... Ali

I have never had a problem with Quality 1 Energy Systems, and my most recent experience was no different. I use them for both my personal residence as well as for the commercial buildings that I manage. I have used them for new installations and service calls. I have also personally recommended their services to other commercial property owners, who have relayed to me that the great work and customer service was extended by Quality 1 to those owners.

Bank Of Whittier from Richardson hired Quality 1 Energy Systems for servicing. They are punctual and has very fast service even during this COVID19 period. The technician is knowledgeable and the price is competitive.

Technician came back out to change out our AC filters in our Liebert unit. Did an excellent job.

Great experience. They were extremely competitive on pricing and the product, installed was great. The guys paid a lot of attention to making sure the house cooled evenly and re-worked the ducts to improve the house. Much more efficient and most of all, cool!! Great company.

Family-owned operation takes pride in their work. Easy to work with and backs up their products. Bought 2 A/C units from them initially in 2011; then purchased a unit for rental property in 2015. Performs yearly maintenance.

I recommend this business for a/c related needs. They have been our go-to for over 10 years. Recently our ducts started sagging, preventing proper air flow, so they sent a tech out to rehang them. In one afternoon we had better cooling.

Great company with a greater staff and customer service. I love and appreciate what you did for me last year on my unit and I now live Denver Colorado. Great job y’all

Great Service and very competitive prices, i used them more than once they are always on time, Fast response Highly recommended

The most honest company I have ever dealt with. They replace the AC unit on my house three months ago and it is working GREAT.The price was excellent....I called them for my Dads house and they fixed for little to nothing.Other companies wanted $$$$$ to replace.I highly recommend them.Remember Honesty is rare nowadays :)

Quality 1 Energy was quick to help solve my problem. They were very professional, and understanding. The install went quick and everything was a 5star rating.I would highly recommend them for their excellence and high quality job the did.

Quality 1 is a solid mechanical contractor who is resourceful beyond their means and always exceeds my expectations. It is refreshing to work with a trade partner who does what they say and says what they do. I am looking forward to the next opportunity to work together.

Excellent service, as always. Explained service problem to me and provided options with pros/cons of each option. Will continue using Quality 1.

Quality one has exceptional service! They are very responsive and knowledgeable. They saved my company over $600!

This is the best HVAC service I have received. I would never call anyone else!

It has a long track of Quality 1 Energy Systems. They have been always on time and the most important thing that they have the honesty with competency. In the most recent issue, I could have paid $1200+ for nothing when I decided to get a second opinion using Quality 1 Energy Systems. It turned out to be a simple tuneup issue. Everything is working great. I wish there is higher than 5 stars!!!

Quality 1 is a great company with knowledgeable, friendly and professional staff. They installed our HVAC system when our building was constructed and have been taking care of the maintenance as well with quality results.

Very happy with the prompt service. Sid was professional and would definately recommend.

Quality 1 is a good company for all your AC and furnace needs. I highly recommend this company to all my friends and family.

Zak (Q1ES) is a honest and responsive person, also his Team are reliable, knew what to do. A good quality company, as I always call them for my HVAC problem.

Thank you so much for attending our call. We highly appreciate your great services and high quality, we were worried that we were going to have to end up replacing the AC unit, however, now we have a peace of mind. I highly recommend this company, they take care of you and provide you peace of mind. Thanks a lot! We trust you.

We have been using Quality 1 for a number of years, and they always give us fantastic service. We highly recommend them!!!

We have used Quality 1 Energy Systems for at least 4 years and they have installed 2 new ACs and will continue to use them. We highly recommend their service!

Great service and competitive pricing. I used quality energy system couple of times and they show consistency and professional work.

Quality 1 was awesome, they were cheaper than everyone else for a new Trane unit. Installation was done professionally, they were clean inside the house and they were on time.

Quality 1 provided excellent service. They were able to diagnose the problem quickly, and completed the repair successfully the same day. Their support/scheduling staff was also very friendly and accommodating. I will use them again.

Quality 1 replaced both of my HVAC systems. Their pricing was competive and the service was professional. I would definitely use them again for future HVAC work.

I love this company. they are responsive and professional and provide quality work (fix it the first time!). I highly recommend them.

Stop looking, this is the company you need to quickly resolve your AC issues. For 3 years Said has been our go to guy for our AC issues. We have 3 so we APPRECIATE his reliability and expertise. I recommend them to everyone for a reason - They are That GOOD!

I have good experience with this Company, Zak was professional, trustworthy and schedule oriented person. He helped me out for emergency, even I was new customer. I got very reasonable charges. Definitely I will be his loyal customer for next job.Thank you Zak.Matthew Tjahjono, University Park, TX.

Quality 1 Energy Systems is a pleasure to deal with. They are punctual, knowledgeable, efficient and reasonably priced. I recommend them to my friends for their A/C needs.

I contacted Q1ES to check on my AC system in the summer of 2017 as it was not working efficiently. I was told that there was not a problem and that I just needed to change the air filter. The next day the unit started making a loud banging noise. I called them back out to investigate and the same technician found a large piece of foam that had been dislodged by his prior investigation and found it’s way stuck in the motor. The foam piece was removed and I was charged another service fee. Several weeks later the unit stopped cooling completely. I had a different company come out to investigate and they found that my unit was completely empty of Freon due to a leak. At the initial investigation by Q1ES we specifically asked about the Freon level and were told it was fine. I find it hard to believe that the cooling problems we experienced just a few weeks earlier were unrelated. Ultimately the other company repaired the problem and now my unit works flawlessly. I am very dissapointed in the service that Q1ES provided and I can’t recommend them to anyone. Not only did they not fix my unit, but they made it worse and charged me an additional fee to fix the problem they caused during their first visit.

This company always responds quickly and is great about figuring out the source of the problem, then fixing the problem quickly. I would highly recommend this company

Excellent service. Experienced crews. Awesome friendly people

Quality 1 Folks always have been there when we need them..Thanks for you great services

We Highly recommended Quality 1 Energy Systems!They replaced both of our HVAC systemsand their service is excellent.

Our A/C went out the day before we were planning to leave town with my mother and children staying behind. It was the middle of summer and we needed service fast. Quality Energy Systems was responsive, helpful, and got the job done quickly and with quality. They also gave us the lowest quote. Thank you to Mohammed and everyone for taking such great care of us!

Always reliably great service!

Great service, with a family feel. Thank you so much for sorting us out!

Very professional and experienced.

Julian was fast, efficient, and there was no mess! Theyre the only company Ill use for my fireplace maintenance.

Excellent service technicians, clean cut, knowledgeable, fast...this company is top notch I will not hire anyone else to do my residential HVAC work.

Good peeps.family businessAnd quality service

They did a great job. The technician was on time and did a very professional job. I would highly recommend them.

Q1 is a great subcontractor for us that is reliable and always makes sure the job gets done right! We have been using them for 3 years for all of our commercial projects.

Mohammed and his team at Quality 1 Energy Systems are on point when it comes to HVAC inspections, repairs, and replacements. Ive used this company multiple times for various clients around DFW, and Im always satisfied with their professionalism, responsiveness, communication, and pricing.

I first began using Q1 when I moved to Dallas in 2011. I hired another company previously who was unable to repair my AC and called Q1. They came in and found that my thermostat was bad. Since then, I didnt bother going with anyone else. I am sure there are many other low cost AC companies but 1 mistake and I end up paying more and have to go through multiple repairs. Since then I have had Q1 service and replace my unit!

I called to schedule a servuce call and they were able to help me immediately. The technician was extremely helpful and explained everything that was wrong before fixing it. Definently recommend this company!

My go-to AC company. Always extremely helpful and timely. The service is excellent!

Good people to get job done faster and professionally, my strong recommendation for anyone who needs air and heat services, deficiently try these guys.

Great family owned company. Worked with me on price so I could get back in service. They are now my goto for all my HVAC repairs! Thank you so much!

This family owned company offers nothing less than great service!

I have been using this company for over 25 years for my house and business and have always found them to be honest and reliable. I would definitely recommend them to anyone.

We have used Quality 1 Energy as our HVAC subcontractor a couple of time. They did good work, manned the job and stayed on schedule. We would use them again.

Great experiences, good pricing highly recommended,
