Today we visited this house for the first time in months. As usual we have a look at the air filters condition and "et voila!"
The air flow was restricted to a minimum, the filter was about to collapse. I would not want to pay the electrical bill for this house during the Nevada summer.
Changing your air filters is important, if you do not, your A/C will cost a fortune to run, it will damage itself by clogging up the evaporative coil, the air will find ways to bypass the filters and your lungs will do the rest of the cleaning. Nice, isn't it? Not at all.

Let's be smart and proactive.
