I have used Chowning Heating and Cooling for the past 6 years, from when I moved into my house here. They installed the heating and air conditioning system, two WiFi thermostats (upstairs and downstairs) and also a damper system. They now come out twice a year to do regular maintenance checks... I am very happy with them and would recommend them to anyone.

Justin was outstanding. He made sure all the work was done correctly and fully explained the work he performed. He even made friends with my German Shepherd so he got 5 stars with her as well.
