What to expect when you call 3N1
Heating failures often happen at the worst possible time. Whether it's a furnace that won't ignite, a heat pump that's blowing cold air, or an electric system that's short-cycling, we diagnose the problem completely before recommending any repair. Our $79 diagnostic fee is applied to your repair — and our pricing is always upfront.
Our non-commissioned technicians are focused on solving your problem correctly — not finding reasons to sell you something you don't need.
