In Keller, TX, furnace repair costs typically range from $80 to $3,500+ depending on the component.

Recommended unit for Keller
Given Texas’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most Keller 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.

- 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.
