A little irritated today. I have a lot going on, so much that I was only able to get 3 hours sleep. I wanted to go back to sleep after dealing with some morning stuff, but the heat cut off....again. My landlord always talks about how the furnace is brand new and there shouldn't be anything wrong. The HVAC guy told me the furnace is 24 years old. Old people, they buy something decades ago and still talk like it's brand new. Gas furnaces last 15-20 years...it's probably dying especially since the last tenant (was here 5yrs) never cleaned the filter (or the house, but thats a whole other story).When I moved in, the reusable filter was so dirty there was 1/4" of dust on the outsides and half an inch trapped between the 2 screens...it hadn't been cleaned in years. I wont be able to sleep much tonight either because I have to be up at 430am for a 4 hour drive.
