This turns into Best Heating & Air once at least 3 of these have likes from 3 or more different locals. No likes here yet. Used one you'd send a friend to? Open it and give it a like.
Before you hire: Heating and air contractors hold North Carolina heating licenses (H-1 to H-3) from the same state board as plumbers. On a full system replacement, get at least two written quotes that list equipment model numbers so you can compare them line for line.
