Advanpro Furnace & Duct Cleaning

Advanpro came to our house on January 13, 2022, to do a Furnace Tune Up on our 10-year-old furnace. The tech took off the cover and said we had a leak. We saw some moisture and rust from the clear collector box. The tech said the metal behind there is aluminum, not as durable, and it would be wet behind there and trashed also. We were surprised but trusted him, and he gave us a quote for a new furnace ($7k). The tech didn't use any tools or do anything to the furnace. Just the visual of that leak and a quote for a new furnace, and we paid $104.95 for the visit. We got three more quotes, and one of the companies asked why we were replacing a 10-year-old furnace. I told him what we were told by the tech from Advanpro, and he said no, that is incorrect and proceeded to show and explain to me why. He explained that the clear collector box in this furnace is known to leak. It isn't a matter of if they will leak, it is a matter of when. He said it hasn't been leaking for long and examined it further. He explained that the aluminum part behind (the part that Advanpro said was trashed) is meant to be wet because our furnace is a condensing furnace and it was functioning fine. He sourced the part and sent a quote the same day. The new furnace company replaced the part and said it is a known issue with these furnaces. The new collector box is black and not clear. They also used a camera to inspect the secondary heat exchanger. It is functioning, and there is no sign of leaking from there. They checked the operation of the furnace, and it is all ok. I called Advanpro on January 17, and the sales manager called me back. I explained our situation, and he was surprised and apologized for their tech not doing "due diligence." He said he would talk to the admin about a refund.
