Excellent company have been using them for over 20 years. The are professional and quality work. Adam was the technician that came out to our home. Very respectful responsible and polite young man. I recommend them to everyone. Rose is excellent and always make appointments to help their customers. Thanks guys.

They did an excellent job at cleaning the humidifier, checking my furnace, replacing the air filters, and ensuring everything was running well and clean before the winter. I would recommend them again, great service.

Great service. Ive bee using them for years. Wouldnt change.

Great and friendly service. I wasnt pushed to buy something I didnt need or want. They got my new AC and heater done in 1 day! I definitely recommend using them.

Brian has been coming to my house and servicing the furnace and a/c for many years. He is always knowledgeable courteous. He definately puts the service in customer service. He is a GREAT asset to your company. I appreciate Brian, Rose, and everyone associated with Algonquin Heating and Cooling.

Great company, highly recommended. Called for an issue with my heater and they came out same day. Replacement was done quickly after. I appreciate the attention to detail. In addition to installing the new unit Brian cleaned up a lot done wrong by the previous owner. Unit looks great and is functioning even better!

I hope everything is ok, weve called for a few days & sent emails but they havent returned any messages and the voicemail box is now apparently full. I hate to give a low rating but we cant go any longer with a broken air conditioner so we needed to schedule an appointment elsewhere. Hopefully others are luckier than us, I want to see local businesses succeed.Edit: Im not a competitor, but I did use one to have my A/C fixed. Rose doesnt believe I tried calling or emailing but I can likely show her my call log & browser history; my wifes as well, she (Daniela) called twice and left messages before I took over the task. Very disappointing response from someone in the business for 37 years.

Algonquin Heating & Air came through for me. While we had a furnace replacement scheduled, my existing control board died 6 days before the install date. In February! They were able to pull up the install date to the next day. The entire install took only about 5 hours.

I had an issue with a humidifier. Everything was handled quickly and efficiently. Brian, the technician who worked on this was both professional and very knowledgeable!

Great customer service. Dependable and affordable!

We had a great experience with Brian, he was very courteous, punctual, and knowledgeable. He worked quickly to locate the source of a leak near our furnace, and fixed it with no fuss. Very fair pricing and tremendous service. We will be using this company (and requesting Brian) again!

Called in the morning to repair my furnace and Brian was out by noon the same day. Had the part I needed and completed the repair. Will be using them for all my A/C and Heating needs in the future. Great company!!

This is Will Pfister writing this review. Algonquin Heating & Cooling installed are new Lennox furnace and AC unit in our historic home in the old town section of downtown Algonquin. Built in 1862. The furnace has been in since 98 and AC unit was installed in Y2K. They also ran duct work for our family room taking it from 3 season to 4 season access.Great service, very knowledgeable staff and technicians. Minor capacitor issues over the years, but overall fantastic performance for both Lennox units. We highly recommend this business for your HVAC needs.

I have used this company for several years. They are always punctual and professional. Brian was our technician to service our furnace today. He checked our humidifier and noticed that it needed to be cleaned and serviced as well. I’m always sent a reminder card along with a coupon when its time to service which I love. I highly recommend Algonquin Heating and Cooling.

Algonquin Heating & Air Conditioning has provided excellent furnace and AC services for my family for many years. Recently our AC died (after 30 plus years) and they respond immediately and replaced the unit the next day. Service was timely and professional. The techs were friendly and safe. I recommend this company to anyone looking for quality service.

I called this morning and they were here within an hour. Brian was great, did a nice job giving our furnaces a tune up. I know who Im calling if I ever need service!

This was my first time calling this business for routine furnace and AC maintenance, and I would recommend them to anyone. They were at my house less than 24 hours after I called to make an appointment. The technician was very friendly and professional, and he did thorough work on both systems. He was able to quickly fix a water flow problem for my furnace humidifier, and he also added some freon for the AC unit. I will be calling this business again next year when its time for the annual maintenance.

Great experience. Quick response and will call them for all HVAC maintenance, in future. Thanks Brian!

We had a heating unit that was 20yrs old. Today we replaced it with a Carrier unit. Brian is professional and very knowledgeable. We have used this company many times in the past and will continue to use them for all our heating/cooling needs. Wonderful easy experience.

We have used Algonquin Heating and Cooling for a few years now typically with Brian as our service man. They always provide excellent and timely service. They are quick to solve the problem so you can get on with your day. We will continue to use them for the foreseeable future. As a bonus they send coupons in the mail too!!!

We used to call a very well knowncompany for our HVAC needs. I wanted to give this local business a try since I drive past their building every day. Im glad I did. They are just as good and a better value. Professional and responsive. Well call again.

10/1.2020 John Dee --- We recently moved to Marengo and I called to get my furnace cleaned and checked. Brian came out to do the job and was very informative and explained everything. Unfortunately the furnace was old and corroded and needed to be replaced. Brian came out today and installed a new furnace. He did a fantastic job checking everything. He found a venting problem and fixed that too. Very happy with him his partner and the company. FIVE STARS

We recently contacted Algonquin Heating because our air conditioning wasnt cooling properly. Brian came out and checked the AC unit and gave us different options to repair or replace it. He didnt pressure us into any decision but we decided that since our unit was quite old we would get it replaced. They came out the next day and installed the new unit and its working great. They were very professional and took the time to answer my questions. We are very satisfied with their service!

Brian was very knowledgeable as well as helpful, they were able to get out to us in 1 hour. Highly recommend them!

Called late they came the next day Worked around my schedule. Brian was very Helpful, Knowledgeable and curtious 👍

The gentleman that installed my new furnace and A/C the other day were very polite and professional. My A/C cools better than my old one ever did. They were very clean and tidy with the whole job. I would recommend them to everyone. I was very pleased with the job.

After some initial delay in service due to miscommunication when setting up an appointment, Rose rectified the situation by having a tech out to our house almost immediately. The tech, Brian, was thorough, explained the process in detail, answered all of our questions, and had our central air working in no time. Locally owned, Great tech, Good service, Reasonable prices.

I’m new to the area and needed a humidifier for our furnace. Brian came out to our home and was very informative in describing the product and how it would be installed. Brian was very professional as a sales representative to the point where we requested if he could do the installation which he did. He did a very prompt and neat job. Would definitely contact Algonquin Heating for any future job. Very thorough in explaining the operation of product.

It was an absolute pleasure to work with Rose, Brian, and the entire Algonquin Heating and Cooling Team. They came out quickly to diagnose our issues, were extremely responsive and communicative the entire time, and worked to schedule our installation as soon as possible - this was greatly appreciated considering our AC died a week before the hottest day of the year! Thank you so much!!

Had Algonquin Heating and Air Conditioning out to the house a few times. They are quick to get service to the house.We were fortunate to have Brian as our technician every time. He is very professional, efficient, knowledgeable, and a very nice guy.Cleaned up his work and was respectful of our home.Great job. Highly recommend.

Very happy with the service that was provided and the speed at which they could replace my damaged furnace before the weekend. Brian was very knowledgeable and accommodating for my needs with the whole experience. I will be calling them again to service my other property. Big thumbs up!

Great service and on time. I appreciate that they dont try to sell me stuff I dont need. They recommend things but never pushy. We have been using them for years at our own home and a rental property.

They were able to give me a same day appointment. The tech that came was knowledgeable and made me feel like I was getting my money’s worth. I felt the prices were fair and would definitely use them again.

These are my go-to guys for HVAC tune ups and regular maintenance. Very friendly and professional to work with. Highly recommend this company to everyone for your HAVC needs

Brian is always prompt, patient with inquiries and speaks at a level consistent with a homeowners knowledge. Charles Ondrusek

Excellent company to do business with, Brian was very knowledgeable and honest. Purchased a new furnace and wasn’t pressured to buy any extras or more expensive furnace. I highly recommend Algonquin Heating..thank you!!

We’ve been using this company for over 20 years. Invariably, we get a young man by the name of Brian. We see him twice a year for typical maintenance/tune-up of our furnace & A/C. He is professional, friendly, honest and knowledgeable. He always makes sure to let us know the condition of our units and what we might encounter going forward. He is on time, thorough and a pleasure to deal with. A great guy and company.

Had a great experience using Algonquin Heating and Cooling. The technician, Sam, was on time and very nice. He was able to get my furnace up and working during the same appointment which was a huge relief since it was extremely cold outside. Very thankful.

Great company. Have used them many times!

Been using AHAC for many years. Great local company !

I have been using Algonquin Heating & Air Conditioning for past 6 years and they have been amazing. We use them for both our Heating and Air Conditioning Tune-Ups every year and all their staff is very knowledgeable, friendly and reliable. We had an issue with our furnace last winter and they came out the same day to fix it. I highly recommend Algonquin Heating and Air Conditioning!

The services provided by Algonquin Heating & Air Conditioning regarding the installation of a new Lennox AC unit were completed in a professional and courteous manner. The safety and social distancing protocol followed by their team was terrific.

We recently had our complete HVAC updated in our Huntley townhome. Brian listened to our needs and budget considerations, plus he made sure we got the proper size units for our home. Brian and Matt installed the units in one day, and were very considerate of our home, too. We highly recommend this company and their outstanding employees!

I thought the good ol days were over, where everyone was down to earth and actually cared about you as a lifetime customer. I have used Algonquin heating and air conditioning for years for my small needs but today I got the ultimate dream of a garage heater because my wife said if it was affordable then I could do it!!I trusted they would quote accurately and that they did. Always the same person when I call Always the same tech when I have service done. So nice, like the good ol days!

I was very impressed with the service and value. I will certainly be using them in the future.

Brian is knowledgeable and excellent to work with... Highly recommend this company!!!!

This is a top notch company... Always treating customers with utmost respect.... Very knowledgeable about their business, smart and efficient in every aspect of the job... Brian is totally down to earth and so very good at his job.... Hes the face of this company for me.... Algonquin Heating & Air, YOU ROCK!!!

Our furnace went out & someone was able to come & fix it that day. They were able to work around my work schedule & arrange a time that worked for me. The technician, Brian, explained what was wrong & was able to fix it in a short amount of time. He was very knowledgeable & was able to answer all of my questions about our furnace. They were very affordable as well.

Have always had excellent customer service and work performed by Brian. Its always reassuring to know hell be the one servicing our boiler after many years. Rose, the office manager, has always answered the phone and arranged our appointments. We can always count on them to be punctual and organized.

Quick visit. No up charge talk. Local professionals serving local residence. I will use them for my business location as well now.It’s nice to see a company that is personable and wants to earn trust. Wish I would have found them sooner. Thanks Rose, Sam, and Brian.

Ive been using Algonquin Heating & A/C for several years now. Whether Ive called them for routine cleaning or for actual repairs, they are always friendly and professional. They work quickly and dont leave a mess when theyre done. When Ive had to call for repairs, they fixed my problem for a reasonable price. I would definitely recommend this company.

I had a furnace issue on a Friday morning and called Algonquin Heating and Air Conditioning after several of my friends said how pleased they were with their service. I called and within an hour they had a technician at my home. He diagnosed the problem, located the part, and had my furnace fixed within a short period of time. The office person and the technician that I worked with were both very friendly and professional. I am so glad I chose this company out of so many that are in the area. I will definitely use Algonquin Heating and Air Conditioning in the future as well as recommend them to family and friends.

I saw one of the Algonquin service trucks at our neighbors across the street and called the office. As soon as the service man finished there he came over and serviced my AC. He checked everything out and wore his protective mask too. I was thinking about changing my HVAC company and Im glad I did. I learned that my neighbors have been using your company for 15 years.

Algonquin Heating and Cooling are all around great. From phone calls and responses to on time/early arrival, fair prices and knowledgeable, adaptable staff. I’ve had others HVAC companies to my house who did poor work; which kept me looking until I had Algonquin Heating and Cooling technician, Brian on-site. He cleaned up what the others had left as ‘good enough’. Proper is the way Brian finished the work. I’ve finished looking around. Kudos to you folks, for having a good group working together

Always a pleasure to work with Algonquin Heating and A/C. They have been doing our furnace and A/C check up and repair work for over 20 years. Always get prompt response when we call them for service. Brian/Rose and the whole crew there are the best. I highly recommend Algonquin Heating and A/C for all your HVAC needs.

Had a very pleasant experience. Friendly and flexible customer service in making appointment. Brian our Technician was professional, courteous and knowledgeable. Diagnosed and fixed my issue in one visit also made recommendations. I recommend these folks!

Have had Algonquin Heating & Cooling servicing our furnace and air conditioning for over 20 years and they have always been great. Timely, professional, friendly, and cost efficient.

We have used Algonquin Heating & Cooling to service our home since we first became homeowners two years ago and look forward for the continued great service. Especially happy with the way they help us understand the proper care of our equipment and walk us through the necessary steps. Thank you!

I had a great experience with Algonquin Heating and Air. My furnace wasnt operating properly and they sent someone out to diagnose my issue quickly. The service man was knowledgeable and explained everything throughly! Will definitely call for any future issues I have.

We have been customers of Algonquin Heating and Air Conditioning for well over 15 years. They have provided excellent service from annual air conditioning servicing to complete furnace replacement (which was done within one day of an emergency call one December after the furnace failed completely and the temperature as falling fast!). Always prompt, informative and courteous service. Thanks!

We support local business and they are the best. We purchased our furnace and AC unit from them about 4 years ago and have never had an issue. Great prices and good service on our yearly check up.

Quick to respond, sending the most efficient technician (Brian)I have ever had at my home. A fair price and easy to do business with. I will call on Algonquin Heating again when I need service.

We have been using Algonquin heating and air since 2007 for our yearly furnace & A/C cleaning and check-ups. Prices are competitive and the service is excellent (Brian is always our service tech). All personnel are friendly, knowledgeable and honest. We highly recommend this reliable company.

We have worked with Brian at Algonquin Heating for many years now. He is very knowledgeable, sincere and dependable. We bought our furnace from him and are very happy with it. We recommend Brian for someone you can count on.

My wife and I recently moved in to our home that was not well taken care of by the previous owners. We had a pleasurable experience with Algonquin Heating & Air Conditioning. I have an above average knowledge of the equipment in our home, but I dont have the experience to tell how much life is left in the equipment/ or am capable of QUICKLY troubleshooting. I love to learn everything that I can, but dont like peek over the shoulders of those that have a job to do or tie them up in conversation. The technician that came out was very friendly, went out of his way to engage in conversation, did his best to fix everything with out trying to sell me parts, informed me of the life expectancy of our equipment, and even found parts that I was unaware I had that was left behind by the previous owner. I would recommend this company even though my phone call was never returned when I was looking for a job ;)

Really great service, reasonable prices. Bryan always answers my questions with easy-to-understand information so that I can make informed decisions. Ive done business with Algonquin Heating & Cooling for several years and have learned to trust them.

Been using Algonquin heating cooling for last 15 years. Very satisfied with the work.Brian is a great tech we will recommend to family and friends. And continue to be loyal customers .

We have been using Algonquin Heating and Air Conditioning for many years. Brian has been our technician and he is AWESOME!! So trustworthy and extremely knowledgeable. Hes always honest with us and for that reason, we wouldnt even think of going anywhere else. Our furnace was 27 years old when we had it replaced. It was still working but felt it was time to get a new one right before the winter. I honestly believe it lasted that long because of how well Brian serviced it. Our air conditioner is 28 years old and still going strong! :-)

Brian did a great job as usual!

They did a amazing job! Very clear and knowledgeable and answered all my questions. I will be using the again for sure.

We just used Algonquin Heating and Air again for our routine furnace maintenance. Each time the service rep has been very professional. Their service rep never pushes for unnecessary work to be done as experienced in the past with other similar companies. We have never had an issue after they leave; as have experienced with other companies too. There is a reason they have been in business for so long. Highly recommended.

Brian has serviced my equipment for 15 years and has always done an amazing job. He is always so kind and polite. I would recommend this company for any work that is needed.

We just had Algonquin Heating out to see why our heat wasnt kicking on. They were over within a half hour and their technician was very friendly and knowledgeable. He fixed the issue and got our house warm quickly which was very much appreciated with 2 babies in the house! Ill be sticking with these guys. Thanks!

Since we purchased our home in 2009 we have used Algonquin Heating and Cooling for both our furnace and AC. They are fantastic! Brian keeps us updated on condition of both units. Hes never tried to push for things we dont need. Id recommend them to anyone!

We called for service on our furnace. We had Brian come out within an hour to our home. He was able to diagnose the problem immediately. He got the part needed & was able to fix our furnace same day. Brian is great! We had Brian from Algonquin Heating & Airconditioning do other service for us before & have always been pleased. We wouldnt go anywhere else. Great place to do business!

Brian once again saved the day! Thank you for fixing our air conditioner.

I have been using Algonquin Heating for over 30 years now and have always been satisfied with their service. Brian is very conscientious and thorough in solving the problem. Rose is always very helpful in scheduling service quickly.

I have used these guys for many years. Brian is the best and very friendly to help me with all my questions every year. I have really enjoyed my experiences with them and highly recommend.

We have been doing business with them for 19 years! They put in our original AC unit in 2001 and just had it replaced in October 2017. They service our air conditioner, furnace and whole house humidifier every year. They are ALWAYS very professional, friendly, on-time and they stand behind their work. Highly Recommended!!!

Brian came out today to fix my air conditioner and was very knowledgeable in repairing it and answering all my questions. He explained my options very well and was able to fix for a very reasonable price. It was a pleasure to work with him today and I will request him in the future.

My family and I have used Algonquin and heating for over 20 years.We wouldn’t dream of calling anyone else.Brian is our usual technician and he is so knowledgeable and takes the time to explain everything.He never tries to hard sell us something that is not needed.Brian just left after servicing my AC and it’s over 25 years old and he told me all my options.If I do decide to replace AC with a new one, you can believe I’ll be calling Algonquin Heating and Cooling.I highly recommend this company and would definitely give it five stars.Toni CaponeCrystal Lake.

Great customer service and professional crew.

Excellent customer service and very prompt response time in arriving at my house. The problem was diagnosed very quickly, and the parts were on hand to make the repair. The technician was very knowledgeable and professional. I will definitely recommend Algonquin Heating and Air Conditioning to others.

They came out and got us a new air-conditioner. Service was quick and friendly. They explained everything before doing it and I recommend using them!

Highly recommended for any Heating and Cooling services.

A young man named Brian came out on Memorial Weekend in the blazing heat. He diagnosed the problem quickly, and was able to get the AC running in no time. He was very polite and knowledgeable.

I have been using these folks for years. They installed my furnace and my air conditioner. Rose who always answers the phones is really nice ALL the time when I call. Brian, one of the techs who comes out is outstanding and friendly. Always takes the time to answer even the most stupid questions since I know nothing about heating and air... All their units work flawlessly. Highly recommend them!!

Brian came for a service call today for our AC. He was up front and honest, very accommodating and fair. Great service and when it’s time for a new unit we will be calling Brian to come and take care of us.

We have been using Algonquin Heating and Cooling for years! They do a wonderful job and are honest and friendly! They have also been very prompt and available when needed. We highly recommend them!

Been using Algonquin Heating and Air for years. Every experience has been great. Brian is professional and has gone beyond being helpful to my family.
