I was waiting for a week for the first AC company to put in my new central air. At the last minute he canceled on me and told me it'd be three more days during the heat wave. I come across comfortable Heating and Cooling I gave them a call he was out the next day and installed it and they were $1,700 cheaper than the original contractor I hired that canceled on me. they did a great job and my unit is working fine fast and friendly service for sure I recommend these people to anyone shopping around

Geoffrey Pruitt Google review · July 2026

Excellent customer service and communication. Josh and his team were professional and trustworthy. We were very happy with our experience.

Jaime Schmitt Google review · July 2026

Josh is very attentive and when I looked on Angi for HVAC after mine had quit and house was 48 degrees, he called and was out at the house within 2-3 hours on a Sunday. Every question, concern,and inquiry was quickly answered and addressed. He did well with setting up equipment drop off. His guys were a little late to arrive on their time frame, but his guys work long hours and were professional and easy to talk with. Had 1 small issue after install and Josh addressed it. I'd recommend them as he's got options to choose from and financing options if needed.
