Hi all, here is my question. I came home from work and the house was cool but I thought I smelled a slight burning scent. After a while I stopped smelling it so I forgot about it. About 2 hours later I noticed it was getting warmer in the house so I looke at the thermostat and the temp had gon from 70 to 78. The unit outside was working but no air was coming out of the vents. I checked all breakers and they are fine.
After an hour I turned on the thermostat and it worked for about 30 minutes and then it stopped blowing through the vents again.
My air handler is in the crawl space and I have not gone down there yet to check it out. I don't know anything about air handlers... is there a fan in there that could go bad? Since the outside unit is running it must be a problem with the air handler, right?
