We had a furnace tech out this morning.
The furnace has been loud lately and coming on for short, repeated bursts.
Then there was a message on the thermostat about "line switch open".
The tech immediately diagnosed a clogged filter. I'm shocked as we had a new one less than a month ago!
But taking it out made the furnace run better. Tech showed me that it was covered with fine white dust, like drywall. But we haven't done anything with drywall.
The problem is that with a clogged filter not enough air gets through to be heated and blown around the house and the pipe leaving the heater gets hot.
So we purchased a new filter -- nearly $60. We have an odd size -- 4" thick.
The other recommendation was duct cleaning.
