Stop in for a cup of coffee

Good Morning Everyone. Woke up on the coldest day for us so far (-26°F) with a cold house. Furnace wasn't working. Checked all that I could and gave up. Called the heating people and left a message. They called me back as I was leaving. Talked with the tech on the phone and found moisture in a gas reference hose. Blew through it, furnace cranked up - heat again. Woohoo!
