Brian is a great guy. Very knowledgeable..he came in talked about things to help with bills. Serviced my AC unit. Fair, honest and to the point. He came on a mother's day Sunday. Get with this guy for your AC/heating needs. No price gouging here. He literally shows you what he is doing and what he is charging. He will be back for all my needs... Jacoy Owens

I had Brian install a new AC and furnace. He is very professional, courteous, and takes great pride in doing excellent work and ensuring the customer is beyond satisfied. He gave helpful tips for maintenance and upkeep not only on the newly installed unit, but other major appliances around the house. He even identified a gas leak at the meter and helped with contacting the gas company for prompt repairs. I would highly recommend Brian to anyone needing an HVAC guy.

Brian & his co worker took out our old furnace & installed a new Heil model in 1 day. They worked efficiently & cleaned up thoroughly. We are we pleased with his service

Brian was great! He answered my text late at night with a phone call and was out early the next morning. Everything was explained thoroughly and tips to help reduce energy bills. Highly recommend him and will use his service again in the future.

Miracles do happen! We called Brian around 7:30am, he promptly returned our call and was at our house in less than 2 hours. He got our ac unit working and a huge weight off our shoulders. To say he is professional, knowledgeable, sincere, and experienced is an understatement! He even relayed tips on how to care for or unit so I will run more effective and efficient. Also cutting utility cost. We will only use The Heating and Cooling Guy going forward:) thank you so so so much Brian!!

Brian recently completed a service call on my very old HVAC system. His rates were rersonable and inline with most other companies preforming similar work. He is highly qualified and very professional in his work. His service equipment and technical tools show how much quality he puts into his business. You should consider giving Brian a call.
