"Found a simple solution to what I thought was a major HVAC problem that would have otherwise led me to replace the unit. Would definitely hire again."

"From not having a water supply for my whole home bypass humidifier, to having a repaired, new water supply line and instant winter comfort. All in less than two hours. Thanks Edmond and team for getting me taken care of right after I arrived home from work. Wealth of knowledge, too, about HVACs warranties, and other good general advice for first-time homeowners like myself! Glad to have signed-up tonight as a member - eligible for discounts tonight and future maintenance services. Highly recommend!"

"Good pricing and quick service. We used them for an HVAC unit in our former home last year and just called them back to install a unit in our new home."

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"Pat Ward has done two jobs for us...relocating our HVAC condenser and designing and installing a super cool custom overflow drain for our basement utility sink (so the sink won't flood out if the drain gets blocked when I'm doing laundry). He showed up when expected, he worked in a clean way, the results were clean and effective, and he was professional in every way. He also might be the nicest guy you'll ever meet. Thanks Pat!"

"Regal did an excellent job on cleaning my air ducts and dryer vent after a remodeling. Very professional and explained everything before starting. I would highly recommend this company."

"Isak was on time, courteous, professional, and he explained to me exactly was he was doing. He made the installation a smooth process. I will be calling for my future hvac needs!"

"Edwin was prompt, polite, professional, but best of all extremely knowledgeable. He definitely â knew his stuffâ and didnâ t try to â sellâ me anything that wasnâ t necessary. Very honest and straightforward. Easy going and patient. Would highly recommend and plan to use him for all my HVAC issues going forward."

"Customer service was communicative but not pushy. The technician, Nelson, was skilled, prompt, knowledgeable and above all else honest. I highly recommend this company and will certainly be contacting them in the future for all of our HVAC repairs and for our system replacement when the time comes."

"Great! He provided additional information, suggesting I install a UV Light Air Purifier to my HVAC system. Which would help eliminate the possibility of mold growing in my vents."
