GAC Services: Customer Reviews

We have used GAC for our seasonal tune-ups for years. It was time for a new HVAC system (ours was close to 30 yrs old) and they were great. They gave us 3 levels of systems in the estimate. We went with the middle. The team of Justin, Oscar and Kameran were on time for our install. They worked efficiently and were COVID-conscious. They wore masks and wiped down surfaces as they cleaned up. They walked us through programming the system and made sure we were satisfied before they left. Our new units are so quiet. I highly recommend GAC for your HVAC needs.

I wanted to call to let you know that the service technician who came to our home today was truly outstanding!! He was quick, thorough, wore mask/gloves/booties, and wiped down all of the surfaces he touched. He was pleasant and professional, and I could not have been more pleased with his visit. I don’t recall his name, but assume it is in our records. I just wanted to let you know how great he was.

I had a complete heating and cooling system installed in my home recently by GAC Services. From the sales process, duct cleaning, and installation, I was impressed the entire way. The sales person sized everything from scratch instead of assuming my current system was sized correctly. Other companies did not do this step and just read off the AC ton size, blower size, and BTU of my current unit and quoted that. It turned out my old system was too big! Further, the installers (Matt, Phil, and Dave) showed up promptly on the scheduled day and finished quicker than I thought. Their installation was spotless and tidy and did not leave a mess behind. I would highly recommend GAC!

I’ve had a maintenance contract with GHAC for years. They always send technicians who know their technology well, are pleasant and courteous, and work efficiently. When it came to replacing my 20-year old furnace and air conditioner, they worked with me to identify a system that was just right for my home – not too large and not too small. The crew of 5 that did the installation worked hard, had excellent teamwork, did a great clean-up job after completing the work, and explained to me how it works.

I value all with GAC. Quality is excellent. Responsiveness is fantastic. Technicians always take our needs into consideration and explain everything.

I have been a customer for over 15 years and have been impressed with the quality and consistency of their excellent service. I have recommended GAC to many relatives and friends and all have been very satisfied. I had some concerns when GAC expanded their company but those fears were unfounded. Thus far, all of their employees have been friendly, responsive, and knowledgeable. They have earned my trust.

This is the second HVAC system we’ve had GAC install for us. We chose them again based on the excellent price and install for our first system and the excellent service we’ve had since. We were again very pleased with the entire process, from estimate to install. Courteous and professional. Highly recommend!

Bruce and John came to fix an electrical problem and ended up helping us make the whole house safer. Previous contractors had left electrical problems which they corrected for us and explained everything along the way. We’ll be happy to recommend them and GAC services to others in the future.
