This is a great company. It was 93 in our bedroom after the ac went out. We called 8 companies and these guys sent someone the next morning. We had a new system installed the day after. Everyone else cancelled on us because it's 100 degrees outside right now. They installed same day, it's clean, wore bags on their shoes. It's already cool in here, thank you so much Gagne, amazing.

Gagne alerted me that Tim was on his way, and Tim arrived earlier than I was expecting. This was a good thing since I was going to be charged for an after hours fee. Tim waived that fee and took care of business in quick fashion. Tim was professional and personable. Tim was an awesome representative for Gagne and he will be the reason I use Gagne again.

I called asking for a repair visit as a new customer without a service contract, and they were able to schedule me for service on the same day. Jeremy came by within a few hours and provided excellent service. He explained all the issues my AC unit has having and the various options and price points to fix them, and the information was very easy to understand. I will be using them in the future for all my AC questions.

Needed a whole new AC/furnace system for the upstairs and Gagne pricing came in the middle of 5 quotes so pricing is on target. Salesperson didn't try to oversell or was pushy, just followed up in a timely manner. Installation was done quickly, within 2 days of the purchase, since we were down and out with no AC in the bedrooms. Very clean and professional install.

I even had a system issue with the main floor system the following day and although it was unrelated and mere coincedence, they helped walk me troubleshoot and I was able to execute a DIY repair! Thanks Rick!

Greg What is thorough and complete extremely polite very knowledgeable not pushing towards other services but did explain everything that was needed and or required in the future to maintain our household cooling system We love Gagne for all their service and repair. They may not be the cheapest but they are provide the best service for their cost. It's important when a company can back their rates. We will continue to be an advocate for them

Super super happy with Gagne. From the service scheduler, Sarah, through the technician Greg and the instillation crew headed by Trey. everyone at Gagne has gone out of their way to be sure we were happy. They explained our AC/Heating options and were responsive to our needs. We feel confident in their work and look forward to their maintenance of our new system for years to come. You'll be in good hands with Gagne!

Tim was awesome and figured out the problem immediately. He had the part on hand, replaced it, and I was back up and running within 30 minutes. Great guy and knowledgeable. Gagne kept in touch with me over the last few days, reminding me of my upcoming appointment. Every time I called the office someone answered immediately and was never put on hold. No wonder they have such high reviews

Just had a great experience with Gagne. The tech, Tim, was very friendly, professional, and capable. He shared detailed pictures and descriptions with me as to what he was seeing and recommending. I ended up doing some additional, needed repairs. I believe I was treated very fairly and received excellent services for the price --- so the value was definitely there.

Greg was very professional. He called when he was 20 minutes from our home and arrived on time. He confirmed what I had scheduled. After regular maintenance he let me know of a few issues that needed to be addressed. He had the parts and was able to complete within 30 minutes. Wonderful! Service: HVAC system maintenance

Great service from Jeremy! The company sent a picture of him before he arrived, so I knew who to expect and Jeremy called when he was on the way. Jeremy was here to do maintenance for both systems and he took pictures of an issue he found in the attic, which was very helpful. Everything was explained and pricing for the repair given before he left, which I thought was a fair price for the job. We had purchased our HVAC from Gagne about five years ago and I thought they had great service then and they continue to! Highly recommend Gagne.

I requested a on-site estimate for a few items, including new HVAC system. Once Ricky Moore showed up and we had a discussion, we quickly realized that I should have asked for a maintenance type of call, and that he didn't have the capability to quote what I needed. Regardless, I spent an hour discussion and looking into the two areas, of which Ricky was amazing help.

While he was on the 'sales' side, he has 20+ years of technical expertise, and was able to give me EXACT information about our existing system. He went above and beyond to see that we discuss and sent information off to his other team. Thanks and will be using them in the future for project.

BEWARE of doing business with Gagne Heating and Air. At first I thought they were a reputable company with all the 5 star reviews on google and Nextdoor. However I learned otherwise and caution anyone using them to not blindly trust them nor these supposed reviews. They offer short-term, band-aid solutions that lead to larger problems over time. I have lost over $1000 worth of repair and maintenance in a year all to end up needing an entirely new system.

If they had done a thorough and proper inspection, I could have saved thousands of dollars. After multiple consultations with other hvac companies, they confirmed several red flags including safety hazards that this company never even mentioned! The other hvac companies said that had these issues been properly addressed my system wouldn't have failed prematurely.

When I brought this up with ownership, they were unwilling to offer any remedy, were condescending, rude, and disrespectful. They told me to take my business elsewhere, which I advise you to do as well. Not only do they not value the customer or your business, but they also are far more expensive than their competitors.

This company was very impressive in its methodical analysis of our problem, an older furnace. Ricky explained our options in depth so that we were able to make a more informed decision. My community on Nextdoor recommended them and I'm glad I used their services.

Rick came out to our house and quickly diagnosed a problem with our unit. He was very good about explaining the issue and the solution. He wasn't pushy at all. He was very patient and nice. I will definitely do business with Gagne again because of this positive experience. Service: Heating system repair

Greg C. was awesome. Professional, friendly and honest. Unfortunately we're going to need to replace our 30 year old furnace. But it is what it is. Homeownership! I also have to say I love how Gagne sends a text w/ a photo of the tech when they are on the way. Smart & very cool. Services: Heating maintenance, Heating system repair

I was referred by a friend and was very thankful that Jeremey was able to come to our home the day before Thanksgiving. We had guests in town and the heating in the bedrooms stopped working (of course). Jeremey came on time (the company alerts you by text, email, and a phone call), diagnosed the problem. Was able to fix it and then perform maintenance on our other systems.

I signed up for their maintenance service because I was so impressed. I am looking forward to a good working relationship (our previous company had closed after the owner retired). Thank you! It was so nice to sleep with the heat on last night!

Six months ago, i purchased a heating and air system from Gagne Heating and Air. I was very happy with their timely quote, responsiveness and installation. As promised they sent Mr. Ricky Moore today to ensure our system and filter were working properly as well as replacing the filter. Mr. Moore was a delight and patiently answered all my questions.

What an asset he is and a wonderful representative for this company. My husband has Alzheimer's and he took the time to shake his hand and thanked my husband for his service to this country. Made his day! Thank you!

We are on our 2nd year of a service contract with Gagne H&A and have been very pleased with the service and quality of their work. Daniel has been our tech and is very professional and meticulous as he services the units. They are dependable and trustworthy

Prompt, neat and clean installation of a "new furnace" whose installation went smoothly and painlessly. Even more importantly to us as homeowners, we know, if needed, The Gagne Company and their reputation stand behind the equipment they install. That is so reassuring! Thank you to Eric and Jeff Gagne and their family of technicians.

The staff was very courteous and prompt in scheduling my service appt quickly. As a matter of fact I can say without hesitation that they provided better service than I have ever had before. Daniel my technician was thorough, knowledgeable and handled himself in a very professional manner. These folks are good. I highly recommend them.

I had Gagne our to my house this last week for an AC tune up, and cleaning, and had a duck repaired. Which i was happy with. When all was said and done i had a bill of $473, which seemed a lot to me and substantially more then i had paid in the past for the same service. Then i received a list of items that could be a problem, in the future, with a large price tag on it. My system is running fine, and will get a second opinion. Feel that they are expensive and come to your house looking to create work for themselves.

I originally removed my review due to harassment from vendor. Decided that is not the right avenue to take for the others to know what we were up against. Our experience was horrible: expensive diagnostics ($199), inaccurate diagnostics (did not work with Trane, just guess work) led to $1200 warranty part removed and cooling problem was still existent (now needed condenser replaced for another $1700, harassing and bullying emails ( will post if vendor attempts this type of treatment).

Eventually had another company actually fix the issue as they contacted Trane while they were at our house. New vendor replaced condenser at reduced cost ($850). New vendor diagnostic service is $75. We had enough and decided to keep our review so others can make an informed decision. Best of luck but we will no longer use or recommend this company.

I have been using this company both at home and at the office for many years. Very professional staff- the technicians are timely, explain the issue and get to work! The owners Eric and Jeff are accessible when needed. And their pricing is very competitive. It's great to have a business like this in our area.

Not impressed with this company. Technician came out and said The system was leaking and because it was an old system he recommended replacing everything which would've been about a $12,000 replacement. Just did not sound right I had another company come out and all they had to do was put 3 pounds of Freon ( much cheaper than first one quoted the cost of Freon) in one system and everything is ago

I have been a customer of Gagne HVAC for over 8 years. They have taken great care of my personal home as well as my clients. I am a Realtor and having a great HVAC contractor is a MUST- and they are my GO TO guys!! Gagne has provided excellent service to me as well as my clients. Their techs are always courteous and respect my home. I would highly recommend.

I just had emergency service by Gagne Heating & AC and all I've got to say is WOW! Lachlan, the service technician that arrived was polite, in a clean uniform and introduced himself in a professional manner. After looking at the AC unit he found that the motor/compressor starting component failed. He gave me an estimate to repair and got it running within 20 minutes. Gagne is where all of my heating & cooling business will go in the future. Rest assured that I will be telling all my family and friends of this AMAZING experience.

Gagne's team of professionals made our AC repair experience short & sweet - from start to finish. We called our Home Warranty company last Tuesday morning and Gagne had a technician at my home within 3 hours! SAME-DAY APPOINTMENTS ARE ALMOST UNHEARD OF THESE DAYS, RIGHT? Well, not for this company (thank goodness since I'm a total cupcake when it comes to sleeping in the heat).

When you live in Georgia - Being comfortable in the August heat is CRITICAL. Gagne understands and they really delivered with amazing service. They dealt with our Home Warranty company swiftly and had the parts ordered immediately. If they hadn't had to worry about the Home Warranty company's process - I think they could have had us repaired right away.

That being said - the very moment our parts arrived from the Home Warranty Parts Vendor - Gagne called to set up the follow-up appointment & I called them back AFTER HOURS no less [around 7pm] this past Monday and Jeff set the appointment for the following morning - between 8am-12noon! Totally ridiculous how easy it was to work with them. Gagne had the repairs done within a couple of hours and we couldn't be more grateful. Please call these guys if you want prompt, professional service. We'll be proud to recommend them to all of our friends - Thanks again Gagne!

Great guys (Eric and Jeff). They are very competitively price, and go out of their way on the customer service. We bought a Trane system from them and have had no problems.

I have been a customer of GHAC for several years now. Scott had come out for an annual checkup last year and he discovered a small leak in the coil of my new heat pump (affects only the A/C). Fast forward several months (and now that spring is upon us) , Darryl and Scott returned to my home and completed my warranty work on a timely manner and it was ALL covered.

Very pleased with the quality and attention to detail that GHAC brings to the table. If you are not using them, you are missing out on a family-owned business that brings its "A" game every day!

We have had our AC replaced about a year and a half ago, if ever we had a problem, they would respond promptly and get it fixed. Even on the unit they didn't replace. I feel very good about doing future business with the Gagne group and recomend them to EVERYONE !!!
Jenifer Anderson
We had excellent service from Gagne - from the initial consultation to the installation. Mr. Gagne took the time to look at the complete system (including attic), which another company's estimator did not. He explained our options thoroughly and provided us with details about our options. As for the two techs Mario and Brent, they were AWESOME! Each very pleasant and personable to work with, answered all our questions, and very punctual! I would absolutely recommend Gagne Heating & Air.

Chris Whitehead was dispatched to service our furnace(s). I was at work during his initial work and returned from work near completion. He arrived early for the appointment, but called first to say he was available and on his way. He was waiting for my wife when she arrived at the scheduled time. She was very impressed with his diagnostic ability and his work ethic.

I returned as he was finishing (using a broom and dust pan to clean the area in the basement around the unit). He gave me a clear explanation of what he did and what he recommended. I knew immediately I could trust him...and his company. I highly recommend!
