Furnace repair cost by part.
Typical Killeen repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Killeen, Texas, where the median home was built in 1994 and the climate is hot-humid with mixed heating needs, furnace repair costs vary by issue. Typical diagnostic fees run $80–$200, and common repairs like flame sensor replacement cost $85–$275, while a blower motor can run $425–$1,600.

Recommended unit for Killeen
Given Texas’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most Killeen homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

- SEER2 minimum14.3 SEER2 (Southeast, <45k BTU)
Federal Southeast-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended

- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
HVAC work must be done by a TDLR-licensed Air Conditioning & Refrigeration contractor, and the licensed contractor (not the homeowner) pulls the required mechanical permit.
