Temp Control LLC tore out my old heating and cooling systems in order to install a new air conditioner and heater. They installers were just fine. They arrived on time, even in the unreasonable weather. They kept my home clean and didn't trek any mud inside or anything. The installers were very pleasant. They didn't smoke or use any vulgarity as they worked. Overall, they did a good job. I would recommend Temp Control to anyone.
