Don’t trust the tenants to change their filters

Don’t trust the tenants to change their filters

I have an apartment building with 3 units. My tenants are not the sharpest tools in the shed. The call me for the dumbest things. I have been called for a plumbing emergency plus then found it was just a blocked toilet. I have been told there is a bee infestation when there is a small nest under the porch. My tenants are helpless. I wanted to have each of the tenants deal with their own air filter on the Heating plus A/C system. I have separate Heating plus A/C units for the apartments. Every Heating plus A/C device has an air filter that needs to be changed once a month. The air filter is the piece that handles any dust from getting in the system. Not only is the air quality improved, however the Heating plus A/C can run longer plus better when less dusty. If left filled with dust, the Heating plus A/C could overheat plus have a reduced lifespan. It is entirely important to put a clean Heating plus A/C filter in daily. However, I don’t trust my tenants to remember or to do it officially, so I have to do it daily. The entirely bad area of the task is that there is not one genre of air filter at the hardware store. The Heating plus A/C units each have a weird brand plus size of filter as well. So I need to take each ancient air filter with me to the store to ensure I get the proper one. I wish there were inserts to put in Heating plus A/C systems. If the air conditioner filters could all be the same size, I would buy them in bulk plus leave them at the rental property.
