GAC Services: Customer Reviews

quotation mark

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

quotation mark

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.

Excellent service, friendly, explained everything, and very responsive. Recommend absolutely, and will definitely use again. Thank you!

Extremely professional, polite and honest! I first contacted GAC 2 1/2 years ago to perform yearly maintenance on my heat pump system and have stayed with them ever since. They just finished a difficult replacement of a 23 year old system and I’ve already noticed a great improvement in the airflow throughout my home. Highly recommend GAC Services.

Our heater broke a few days before the Holidays and in 20 degree weather. With a baby and toddler we needed our heating fixed right away. GAC sent Mike M. to our house immediately to look at the heater and service was scheduled not long after the team came on Christmas Eve to fix our heater. Everyone from GAC was professional and knowledge and made a difficult situation less stressful. Thank you!

My wife and I have used GAC Services for years. We have even used their Electricians. This company is simply awesome. Direct, professional, on time, don’t waste time, answer any and all questions, teach you a few things about maintenance, the importance of maintenance, and are honest as the day is long. I would highly recommend GAC Services for all of your HVAC and Electrical needs!! Customer since 2005

GAC Services handled the upgrade of my furnace and AC. They did a great job, and were very quick, and all of their crew members were very knowledgeable and helpful, and very courteous throughout the whole process. I would definitely use them again for anything else, and recommend them highly.

Kudos to GAC employees Matt, Carlos, David, Marlon, and Dennis for installing a new HVAC system in my house recently. They had to take away the existing HVAC system, both inside and outside, which was 35 years and 18 years old, respectively. Additional duct work had to be performed to make it compatible with the new unit. The only negative aspect was a used motor from the original unit was left behind. Otherwise, a great job! Also, a shout out to salesperson Tim and supervisor Paul who assisted in this transition. Good job!

quotation mark

The GAC service team who installed my heat pump was very professional and knowledgeable. They arrived on time and the installation process was very efficient. The team members answered all of my questions and concerns. Overall, I was very impressed and happy with the job they did

Great service! Our HVAC broke once in the winter, and once in the summer. Both times GAC came out super-quickly to fix the issues. Finally, we decided to change out our whole system and again they came out super-fast and installed it in a matter of hours. Now our HVAC system is working better than ever, which means we can save some $$ on our Pepco bill! Highly recommend!

As always, working with GAC Services is a pleasant experience. I’ve used their services many times and have always been impressed with how knowledgeable and efficient their electricians are. The work is done accurately the first time, and the technicians are friendly and take the extra time to explain what they’ve done and anything else you may need to know for the future. I recommend GAC, AND their electrical services division to everyone! Thank you!

The new zoned system you put in is fantastic. For the first time in 26 years, our upstairs is cool. This intense heat has been a good test for the new system. Thanks so much!

Matt D. did an excellent job of explaining the options available for selecting a new Heat pump system for our home since ours had died. He was very patient and thorough when discussing the options and answering our questions. The installation team (Shaun, Jason, Mike, and Brian) did a great job. Also, the duct measurement rep, Dave, did a great job as well. They even laid down a canvas runner to protect my hardwood floors. Thanks!
