GAC Services: Customer Reviews

quotation mark

GAC sales rep and the installers arrived at my home on time and were professional. They respected me and my home and arrived masked and gloved (much appreciated). The product and the process was explained and all my questions were answered. The installers worked clean and cleaned up after themselves. GAC came highly recommended and I in turn would highly recommend them. Thank you to the sales rep, Eric and to Matt and Carlos, the installers.

Very impressed with every aspect of our experience with GAC Services, from the routine maintenance of our HVAC systems to emergency response/repairs and the installation of new equipment. Highly recommended!

Ermias was my technician today. He called ahead when he was on his way, and arrived within the time frame provided to me from the main office. He arrived, made sure to wear footies for the house, and reviewed my AC system. He was very knowledgeable and took the time to explain some things to me that increased my own understanding of the system, and identified a small repair that was needed to increase the life of my system. I have used GAC before, and I received the same stellar service as I did then. Thank you Ermias, and thank you GAC!

quotation mark

The HVAC technician was very professional and knowledgeable. Great service with high confidence that it’s exactly what was needed.

We just had our heating+ac units (indoor and outdoor) replaced today, on one of the hottest days of the year, and we received such excellent service from Iggy and Cristian. They were extremely professional, punctual, and demonstrated amazing attention to detail; we are very thankful for the hard work they put in today. We also have a very large dog who loves people but tends to growl first, both Iggy and Cristian were very calm and welcoming towards her which made us feel soo relieved! They provided very friendly service and we couldn’t be any happier.

We had our annual air conditioner service and the gentlemen who came was amazing! He was wearing his mask the whole time and wore protective booties! He was professional and very pleasant! He did a great job with our system! We would definitely use GAC for every heating and cooling system needs!

I had a new furnace/air conditioning unit installed by GAC. This was a great experience from the proposal stage through the installation. The proposals were clearly explained and were within my budget. And Matt and his team did a great job with the installation. They were on time and finished before they estimated they would. They explained the process and answered all of my questions very professionally. My system works great and I am very happy with it.

2020: Our electrician Edwin Sanchez came and evaluated our needs for additional wiring for our kitchen and office during COVID-19. He and assistant John added 13 circuits and upgraded the circuit box. They practiced social distancing and wore masks.They added light to the kitchen and laundry room. We are so pleased with the work that they did in 2 days. We highly recommend Edwin from GAC. 2018:Our Electrician, Julian, was on time and did a fabulous job. He changed all the outlets from 2 to 3 prong that I needed him to change. He diagnosed the problem with the flickering LED light and changed out the dimmer switch so it would not flicker any longer. He also suggested a surge protector to put on the power box. We were very impressed with his skills and kind demeanor. We would highly recommend Julian at GAC.

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.

quotation mark

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.
Thanks so much!!!

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!

quotation mark

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.

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.

quotation mark

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!

quotation mark

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.

quotation mark

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

quotation mark

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.

quotation mark

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!

quotation mark

My wife and I have used GAC Services for years. We have even used their Electricians. This company is simply awesome.

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.

quotation mark

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

Always done a wonderful job maintaining our HVAC. Honest technicians!

quotation mark

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!

quotation mark

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!
