The attached text exchange occurred during the most horrendous heat wave in Atlanta in a long time. Note the time I texted Gill and the time they replied. Yes, that's PM. Then note the day and time the Gill technician left my home. Yes, that's how quick and efficient they are - even in a heat wave with hundreds of customers without AC. The Gill team is professional, they are knowledgeable, they are polite and, frankly, good guys and they have fair and balanced pricing. Best of all, they communicate and respond quickly / very quickly. Donna and I highly recommend the Gill team of professionals. Thanks guys!

Had my A/C go out on a Saturday night in July, which obviously isn't something any homeowner would want. I called Gill Heating & Air that evening and left a message. I got a call back within an hour, and after explaining my situation, the rep told me they would try to get a tech out the next day (Sunday) and would call me in the morning. Long story short, a tech is out at my house by early Sunday afternoon, and my issue was fixed within a couple of hours. The tech, Rakesh, was incredibly friendly and knowledgeable, and he even took the time to explain how the various components in my A/C system worked while he was fixing the issue. Considering it was an emergency call involving a part replacement, the cost was also very reasonable. After dealing with numerous HVAC companies in the Gwinnett area, I think I'll be giving Gill another call the next time I have a problem.

Great service. The technician arrived as scheduled. He was courteous and professional and able to resolve our problem quickly. The cost of the service call was very fair. Strongly recommend.

They came to fix an issue for us and only got half of the work done when we had clearly stated what needed to be fixed. Be aware!

Got our air working again within a couple hours of calling. Very fast and courteous.

When I bought my home in Lilburn, the system was old, like 20+ years old. We knew it needed an upgrade. I had 2 other companies give me quotes on our single system complete replacement. I called Gill and they came over like 30 minutes later and gave me a cash price quote far below what the other companies offered...like substantially lower! The other 2 companies were "upselling" me on systems, Gill actually "down-sold" me believe it or not! We had a brand new complete Carrier system installed the next day. It's worked flawless since summer of 2018!

Saagar was fantastic. He gave us a quote, and stood by it despite it taking a little longer than anticipated. Prices were 25-40% lower than the estimates we received. Excellent service.

Great!!

This person was paid for over $1000 worth of work and as soon we closed on the house we began having problems with the unit. I contacted Gil and the 1st thing he said was check the filters. Indeed the filters were old and filthy and causing an issue, however its listed on the invoice he provided that they had been replaced. We also needed a contactor which should have been discovered and repaired with this his initial diagnostic and repair. This ended up costing us a ton of money.

Gill is fantastic. He bought our AC back from the dead over 9 years ago "not certain it would hold" and it worked until the whole system died 9 long years later!! That's honest!! He could have overcharged us then and done expensive repairs and/or replacements but his quick fix that he wasn't sure would hold fixed the problem for nearly a decade. Gill came back this to replace our old HVAC system this year when our heat went out. It was done quickly and very competently at a fair price. My husband and I highly recommend Gill and wouldn't use anyone else.
