They say you should change your air filter every single week. I am talking about the air filter to your central heating and air conditioner system. However for myself and others this does not happen and periodically I have to suffer with some exhausting air quality in our home. This is because in this house that I rent the air filter is actually taxing to change! They have it in the ceiling which makes it so I have to get a ladder in order to even change the thing. And this is just too much work. So periodically I can go 4 to 6 weeks without changing the air filter of the central heating and air conditioner system. I have been renting this house for about 5 years now, however one year I did not change the air filter of the central heating and air conditioner plan for almost a whole year! I was blessed the central heat and a/c device didn’t chop on me. If it did I would have just called the property management and they would have to pay for the Heating and Air Conditioning repair. That’s what they get for not having something done about this air filter localement! I easily do not feel love getting up a ladder all the time just to change the air filter of the central heating and air conditioner system. I system to transport out of here in about 6 weeks anyhow. Hopefully the next locale I get will be better with the air filter localement.
