"We had HVAC issues during a cold front season that lasted for a few days so we needed to find someone quickly before the Georgia weather got bipolar again. We believed that the sensors were dirty or off.
We reached out to Dustin and he was able to fit us in the next day. He was professional. Prompt and provided excellent customer service. He gave us a HVAC tuneup and also discovered that we needed an updated motor because the previous vendor a few years ago had given us a smaller one.
He did some little extra things to make sure that our unit works to its capacity. We are so grateful. Highly recommended."

"We had a carbon monoxide detector go off near our furnace this morning. Dustin came over and verified everything was ok with the furnace and it was the sensor that was faulty. He is always prompt and courteous. I highly recommend this company to anyone looking for an honest heating and air company."

"Dustin was at my home on time. He was professional, friendly, courteous and knowledgeable. He got our system running properly again at a fair price. I would highly recommend Dustin and Alliance Heating and Air of McDonough."

"Alliance is always my first call. Dustin has worked on my split unit and HVAC system a few times, and I’ve been impressed with every appointment. He’s professional, responsive, and fair with pricing. It’s hard to find service you can truly trust, but Alliance delivers EVERY TIME. Highly recommend."
