Customer Reviews

Cindy Gardner — review for Cornett Heating & Cooling
Cindy Gardner - 4 Leeward Court , Annapolis, MD, US
Josh Cornett (and team) of Cornett Heating and Cooling is my GO TO for my home HVAC system repairs plus as a Realtor I highly recommend him to my clients and friends - he’s on my preferred vendor list which says a lot as no one makes it to that list unless they’re tried and true. He’s saved me from costly fake repairs with his vast experience and honesty. Always fairly priced and responsive too. I wouldn’t trust anyone else.

Just completed my semi-annual HVAC maintenance. Technician arrived on time and performed the maintenance quickly and professionally both inside and outside. Answered all the questions I had about the system. Cornett Heating and Cooling is an excellent company from the scheduling process through the entire work process. They are the only company I would use. There is no better company around.
