"Is the furnace broken?"

It does in fact seem chilly.


There was an LED light.

3 blinks.

WTF is a pressure switch?

Could it be the leaking freon that we haven't addressed?

For the furnace?

I am armed with a lighter and a flashlight.

Update: after some research and some tinkering...

More later as I put together an RFP for our HVAC System.
