My boiler quit on a freezing night. What do I check before calling?
Thermostat calling for heat, emergency switch on, breaker set — then fuel: oil or propane tank gauge, gas valve open. On condensing units, check whether the exterior condensate drain has frozen. If none of that brings it back, call (888) 766-1474: on a freezing night, a dead boiler is an emergency, and every hour matters for the pipes.
