AC replacement is pretty much what it sounds like — the old system comes out and a new one goes in. But there's more to it than just swapping equipment. The new unit has to be the right size for your home or business, the right efficiency rating for how much you're running it, and installed correctly so it actually performs the way it's supposed to. A lot of people end up with problems after a replacement because the sizing was off or corners got cut during the install. Air Chill Factor does full AC replacements throughout McAllen, Harlingen, Edinburg, and the Rio Grande Valley, and we take the time to make sure the right system goes in from the start.
