5 Signs Your Furnace Needs Service Before Winter

The first cold front is never far off in Plano. Before you switch the thermostat to heat, watch for these signs.

1. A burning smell that lingers

A dusty smell on the first run is normal. If it lasts over an hour or smells like plastic or wiring, shut it off.

2. Strange noises

Banging, squealing, or loud booms can mean a loose part, worn motor, or dirty burners.

3. Uneven heat

Cold rooms often point to a clogged filter, blocked vents, or a weak blower.

4. A rising gas bill

If your bill is up and your habits aren't, your furnace is working too hard.

5. Short cycling

Frequent on-and-off cycles can mean a dirty flame sensor or thermostat problem.

Safety first

Test your carbon monoxide detectors now. If your furnace just needs a simple repair, we'll tell you. No pressure to replace a system that still has life in it.
