Ok so when we first moved into our house, our two furnaces took in air from inside the house for combustion. I felt that this was rather inefficient so I used to see about finding someone to get the air in from outside the house. Well, suffice to say, this sort of thing was harder to explain than I thought. After the first 3 contractors talked to me, they couldn’t see why I wanted to do this. I was probably explaining it all wrong, but I didn’t have the patience to spend any more than a couple minutes on it. Perfect Climate Solutions, however, understood my issue right away. They came initially to take a look at what they’d have to do, gave me a decent quote, and came back a couple days later. They got the job done in 2 hours.
