FURNACE FILTERS

I have a very young couple renting the apartment above my Garage Shop. I finally had to present them with a letter, telling them that I would be entering the Apartment on the first Friday of each month to check the building mechanical s... They were not changing Filters and had the Smoke detector down, since the batteries died. And.... they have a 9 month old up there.. with no Smokes working...:BangHead::BangHead:
Oh.. Yeah.... And the Clothes Dryer vent hose was clogged as well !!!
