Hello All,
A few days ago, I hired a company to do a complete change out of my 22-year old HVAC system. The contractors installed an air filter "rack" between the air supply plenum and the cabinet containing evaporator coil. They didn't account for the drip pan lip and now when you attempt to remove the air filter, it's stuck by about a half-inch and is effectively unremovable without destroying either the filter, the drip pan, or both. When I noticed this, I also noticed that they sprayed aerosol foam sealant in the gap between the two structures but air is still escaping into that space because there is also loose tape flagging in that gap. I went around the corner and looked at my air return grille and noticed that they intentionally damaged it (opened the gaps). I squeezed my phone into one of the large gaps they created and saw that it appears they overcut the duct board. The foam spray they used to "seal" the gap partially fills the space, but not entirely. Surely this is not correct?
They are coming out Monday to address my concerns, but I don't want them to do an equally poor job at remediating it. I also don't want any toxic materials/chemicals coming in permanent contact with my air supply (e.g., mastic, foam spray, etc...).
How should this properly be repaired? I'd like to educate myself. Thank You!
