My heat wasn't working in the middle of December. I called a couple places before calling Perfect Air & Pipe and those places couldn't come for hours. Perfect Air said that they could be here in 30 minutes from the time i called. They arrived on time, with two trucks, and fixed the evap coil for only $225. To replace it would have been upwards of $500. Luckily, these guys know their stuff and could repair instead of replace. I couldn't be happier with their service.
