Goodman manufacturing GMPN080-4 furnace. Ok, so one visit to my son's house yesterday for a hot water heater issue (unrelated) leads to yet another "new home owner" physical plant debacle. He moved into the house a few months ago. While I was out there, we looked for the furnace air filter. Not seeing anything resembling a filter door/drawer/slide. we took to looking inside the actual cabinet. Taking off the main side of the cabinet revealed a 16 x 21 x 1 filter just "resting" loosely against the side of the cabinet where the return air comes in. Yes, it IS between the return and the blower, but it just sort of flaps in the breeze. When the blower starts, it pulls the filter away from the return side of the cabinet an inch or two, and I believe most of the return air just circulates around the outside of the filter. There are no tracks, slides, doors or drawer. It just sits against the side of the cabinet (on the inside), between the blower and the inside of the cabinet. There is one small piece of what looks like coat hanger wire attached at the top of one corner holding it in place. But for the most part it just flaps. It is behind all the wires and safety interlock switch. It does not look like the filter will come out easily. In fact, from the look of the filter, it looks like someone bent the filter in half, to get it in place, and then unfolded it. It looks pretty "jerry rigged" to me. We have looked all over the return ducting for a filter and it appears that this is the only one. So my questions are: 1. Is this a typical means of filtering the return air? I don't have a much experience with hot air systems, but I am very familiar with hydronic. This just doesn't seem right to me. 2. It looks to me like I need to have an HVAC/sheet metal person come in and somehow install a "door/drawer/slide" into the return duct so we get some reasonable filtering taking place. I've never done any HVAC duct work before except for wood stove chimneys, kitchen/bathroom exhaust fans and dryer vents. . Is this something I can do myself, or who should i call? HVAC guy or sheet metal guy? Thanks for your time. Paul/NH
