Welcome!
I am clearing out pictures from my phone and realized that I had quite a few very dirty hvac filters over the last two years. These are from great tenants that moved out and left the house in good condition...
I wanted you to see these to see what you are breathing if you let the filters go more than 4 months. Plus I had to take a service call off their deposit. In one case the compressor had to be taken out and cleaned which cost around $400.
I have plenty of filters and can get more if you need some, thanks!
