I moved into a home (built in the 50's) that had the HVAC recently repaired. Originally (and by error), the owner had one of the returns coming from a opening a vented crawl space. The furnace filter for this return was just jammed against the blower wheel. See photo 1. The system had been running like this for years & with the filter hidden in the blower compartment, it hadn't been changed in years.
I made complaints to local code enforcement so landlord finally removed the return from the crawl space and replaced the ducts, but now it looks like a fire hazard. The original flex is jammed against the new duct and jammed against the drain line. Isn't this against code?
Was going to request an inspection from the gas company today. Any thoughts?
