Came out to check out water heater. As it was stated there was no heat. But there was only no heat to the master bedroom. Rest of the house was staying warm. Cold air blowing out of vents. Master bedroom has a separate thermostat. Checked mech room to make sure that water heater and recirc pump were working properly and they both are, so I believe it to be a thermostat issue. Chris coming out later today.
