I own a rental current home with 3 units, but every unit has their own Heating & A/C equipment & unluckyly, the renters are entirely terrible about air filter changes, then for a while I was always getting phone calls about the Heating & A/C making noise, being inefficient or just not getting the job done.
I realized that clogged air filters were the cause of all their concerns. I told every a single of my renters that once a week they need to change out their Heating & A/C filter. I even provided to pay for the filters so that I could ensure they would do it. Nope, that didn’t help at all. It seemed enjoy I was coming to my rental current home every week anyway on Heating & A/C filter changes. So what I have now been doing is on the first of every week decreasing the current home air filters. Since I have 3 units though, I have 3 odd filters to change. Not only do I have to coordinate with odd renters & find a time that works for everyone, however each air filter is different. I never remember what size, brand & style to get once I am at the store. I wish there was a a single size fits all air filter or an insert that expands to make a filter fit in the system. Typically I end up buying tons of air filters & trying them in each system. The leftover a singles I then return. I entirely need to schedule the right air filters being shipped to my cabin or remember what each rental unit’s air filter looks like. No matter what though, the cooling system filter issue is super discouraging.
