For a long time, I had a terrible HVAC habit, and i decided to curb this habit when I discovered how harmful it could be; The terrible habit I had was letting the air filter go for too long without changing it, sporadically, I would take a look at the air filter and decide that it was still good, despite the fact that it was quite dirty.
I have a tendency to try and get the most out of everything I use, so periodically, I continue to use things that I should just throw away. I have that problem with tennis shoes, cars, and furniture, to name a few things! Well, I can tell you that it is not helpful to become overly linked to air filters that have given up the ghost, so to speak. Such air filters should be relieved of their duties by fresh, clean ones every few months! However, I will admit that periodically, I just completely forget about the air filter altogether! It took deliberate marking on my yearly planner as to when I installed the fresh air filter and when it was time to substitute it. What drove me to start documenting when it was time to change my air filter is my discovery that not changing the air filter of an HVAC system, far from being only mildly destructive, can be the root of just about every kind of heating and cooling system device problem that you can imagine! Simply neglecting to change the air filter could kill the life of your device and cause you to have to make all sorts of overpriced repairs that could have been honestly avoided by a few seconds of toil every few months!
