I always advise my clients at HAVA Tech and Featherstone to either clean or change their air filters once a month. Air filter changes are critical during the hottest periods of the summer season and cold winter months – both seasons find HVAC units being utilized heavily.
Just like your clothes dryer’s lint filter, a dirty HVAC filter causes the unit to work harder in order to keep you cool or warm. Get a paper towel and fold it, try breathing through it, how hard is that?
Now you have a better understanding of why it is important to change the filter. When it comes to caring for the environment, dirty filters waste excessive energy as a result of working much harder. Nevertheless, changing the air filter, which does not cost much, could save you from spending thousands for repairing, or possibly replacing, exhausted HVAC units.
