I recently was studying several things about heating and a/cs online.
And one article I came across was talking about people should make an effort to change the air filter of their central heating and cooling units at least once a week, however this is supposed to bring better air quality in your home and extend the life of your central heating and a/c itself an extra few years.
This was all news to me. And who knows, it is the internet after all and you can not believe everything you study on the internet and many websites, especially when you are clicking several clickable live affixs to get there! But it does sort of make sense to myself and others from a proper sense level! So I decided that I am going to make the extra effort to start changing the air filter of my central heating and a/c at least once a week, but it wouldn’t hurt anything if the article I study was a bunch of bull. The only thing would be that I would spend more on air filters in the course of a year. But then again, I could constantly buy some washable air filters for my central heating and a/c. And by buying the washable air filters this will save myself and others a lot of money all together when I am trying this proposal out. I will report back at a later date with my findings if this is entirely the way or if it was all just internet fables all together.
