We've had a problem with our AC/furnace for the last month and after getting the run around from our insurance and another company (who just wanted to replace both units), we had Cjk come out and take a look. The response time was amazing, they called me around 8am, were at my house around 10, and knew what the problem was by 10:30. They did a thorough job of inspecting my equipment (previous company didn't even open the furnace). The technician then said he'd go get the replacement part and come back to fix it the same day. By 1pm I had a working furnace and AC! I am so impressed by this company and will recommend them to anyone who needs HVAC repair!
