A few years ago the motor in our HVAC died, fortunately in spring when we didn’t need it much. After he repaired it, the guy noted that it was really sucking in on the return ductwork, but the paper filter was okay, implying that the return duct wasn’t large enough.
We have an electrostatic air filter on our HVAC, installed by the original owner of the house, that the tech didn’t know about, and I just didn’t think about while he was there. After he left, I remembered it and checked it. I had been cleaning the two larger “cartridges”, but I either forgot or didn’t know that there were also fine screens above them. Those screens were clogged…badly. Oops.
Cleaned them up and now the HVAC works well. Well, as well as it can given there’s ONE air return at the top of the steps…so the upstairs is always a few degrees warmer.
