Is $3,900 to replace control board, clean coil, and perform AC tune-up a fair price?
Project Details
My furnace is blowing air but not heating up, although the AC seems to be working fine. The first technician claimed there was moisture and a burnt control board, quoting a high price ($3900-$4100) for a repair that included replacing the control board, cleaning the coil, and an AC tune-up (like a unit rebuild). He wouldn't provide an itemized list before the work, which felt like a red flag, so I cancelled and got a second opinion. The second technician said the issue is with the gas valve. He tapped it and wiggled a wire, and the heat worked intermittently, confirming his diagnosis. He also confirmed the AC is working perfectly. He mentioned my husband could potentially replace the gas valve himself, as their company would charge $600-$700. I climbed on the roof and took pictures of the system to see if there are other visible issues like moisture or a burnt control board for possible future problems.
