Furnace & Heating Repair Cost in Texas (2026–2027 Winter Guide)
Typical ranges Texas homeowners report for common heating repairs. West Texas and the Panhandle see the heaviest furnace use in the state, and contractors book up fast after the first hard freeze — so it pays to know what's normal before you call.
| Repair | Typical range | Notes |
|---|---|---|
| Diagnostic / service call | $75–$150 | Often higher on nights, weekends, and freeze days |
| Flame sensor cleaning or replacement | $80–$250 | Common cause of "starts, then shuts off" |
| Igniter replacement | $150–$400 | The most frequent first-cold-night failure |
| Thermostat replacement | $120–$450 | Rule this out before paying for bigger repairs |
| Blower motor | $400–$1,200 | Shared by your AC — dust-heavy summers wear it down |
| Heat pump defrost / reversing valve | $300–$1,500 | Common in newer homes with heat pumps |
| Heat exchanger replacement | $1,500–$3,500 | Safety issue; on older furnaces, compare replacement |
Before you call
- Check the filter and thermostat batteries. A clogged filter can trip the furnace's safety limit.
- Check the breaker and the furnace power switch (it looks like a light switch near the unit).
- If you smell gas or a CO alarm sounds, leave the house first and call your gas utility or 911.
