I’ve been told by my a/c buddy that the reason our heater won’t click on is the pressure switch. I was also told that with my limited home improvement experience I would be able to change it myself.

Any tips or videos? I got nothing

YouTube video testing and replacing

Should be pretty easy to figure out... havent had a gas furnace in 10 years but it was an easy job to diagnose and replace just by looking at it.

How the hell does that happen? Not the dirt robbers, but for the blower not to be running long enough for any critter to survive more than 20 seconds? Let alone build a nest!!

ETA: might be possible anywhere north of Shreveport.... lol
