GAC Services: Customer Reviews

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

Crew was awesome. Arrived on time- worked hard and answered all my questions. Price is very fair and they help you find any rebates you also get. Highly recommend them if you are in need of HVAC systems.

What a great group of guys- Sean,Edwin,Kameron & Carlos! They did a great job installing my new 16 seer heat pump! Love it! They worked well together and quickly! Very clean and neat! Thank you all for your great service! I will tell all my friends about GAC Services!!!!

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!
