No Heat in Your House?
Cold house, silent vents, thermostat asking for heat that never comes. Before you wait on hold with anyone — us included — run these five checks. About a third of no-heat calls end with one of them.
Quick Answer
Total no-heat usually comes down to one of five things: the thermostat (wrong mode or dead batteries), a tripped breaker or flipped furnace switch, a filter so clogged the furnace locked itself out, a gas supply or pilot issue, or a safety lockout after several failed ignition tries. Everything past those five is technician territory — and in a Central Arkansas cold snap, it's a same-day call.
Check yourself: thermostat, breaker, filter, gas valve, reset | Call now: gas smell, breaker that re-trips, CO alarm, or nothing works
The 5 Checks, In Order
1. Thermostat: mode, setpoint, batteries
Confirm it's set to HEAT (not COOL or OFF), the setpoint is above the room temperature, and the fan is on AUTO. If the display is blank or dim, replace the batteries — a dead thermostat is the cheapest no-heat fix in Arkansas. Give the system five minutes after any change; many have a built-in restart delay.
2. Breaker panel and the furnace switch
Find the furnace's breaker and make sure it hasn't tripped — flip it fully OFF, then ON. Also check the light-switch-looking toggle on or near the furnace itself; it gets bumped in closets and attics more often than you'd think. Gas furnaces still need electricity to run. If a breaker trips again after one reset, stop — that's an electrical fault, not a nuisance.
3. The filter — yes, really
A filter packed with a season of dust starves airflow until the furnace overheats and shuts itself down, sometimes into a hard lockout. Pull it: if you can't see light through it, swap it, then cut power to the furnace for 30 seconds to clear the lockout and let it retry.
4. Gas supply and pilot
Check that the gas valve on the line to the furnace runs parallel to the pipe (open), and that other gas appliances work. Older furnaces: relight the standing pilot per the label instructions. If the pilot won't stay lit, or you smell gas at any point — stop immediately, leave the house, and call the gas company before you call us.
5. One reset, then stop
Cut power at the switch or breaker for 30 seconds and restore it. Modern furnaces lock out after three failed ignition attempts; a reset gives it three more. If it clicks but never lights, runs a minute and dies, or does nothing at all — that's an igniter, flame sensor, control board, or inducer motor, and continuing to force retries just wears parts. Make the call.
While you wait for help — heat the house safely
Space heaters go on the floor, three feet from anything that burns, plugged straight into the wall — never a power strip. Never heat with a gas oven or grill; that's how carbon monoxide ends up in living rooms every Arkansas cold snap. Close off unused rooms, let faucets drip if it's below freezing, and if anyone in the house gets a headache or nausea alongside the no-heat, get out and call 911 — CO is odorless. If your system is a heat pump wearing a shell of ice, see Heat Pump Frozen Over? — and if it runs but blows cold, start at Furnace Blowing Cold Air.
