Step-by-step response
- 1Check the thermostat
Display blank? Replace batteries (most use 2× AA). Display on but not calling for heat? Bump setpoint 5°F above current temp and listen for the furnace to kick.
- 2Check the breaker
Look at your electrical panel for a tripped breaker labeled 'Furnace' or 'HVAC'. Reset by flipping fully off then back on.
- 3Check the gas
Stove burner light? If yes, gas is on. If no — and Columbia Gas isn't reporting an outage — call Columbia Gas at 1-800-344-4077.
- 4Check the filter
Pull and inspect. If gray-black, replace. A choked filter triggers high-limit shutoff on most modern furnaces.
- 5Call HVAC same-day if none of the above worked

What's the cheapest possible cause?
Dead thermostat batteries — $0 to fix, you just need to walk to the kitchen drawer.
When is no-heat an emergency?
In NW Ohio: under 20°F outside, infants/elderly in the home, no working space heater, or pipes at risk of freezing. Otherwise it's same-day, not now.
I'm a renter — what are my rights?
Per Ohio Revised Code 5321, a landlord must keep the unit habitable, which includes heat. After written notice (text + email is OK), they have a reasonable time (usually 24-48 hours) to repair. Document everything for security-deposit + rent-deduction options.
