We had a new AC system installed by Precision Heating and Air. They did some duct work as well and redid some insulation in the attic. Essentially, it was a big overhaul. They got everything done fairly quickly and things are running pretty well. We had to follow up once for an issue with the system but that was taken care of quickly. I'm pretty satisfied so far. The price was reasonable. This was my first time using their service but I would probably go back. They're a decent company with good customer service.
