How Much Does Furnace Repair Cost in Houston? [2025 Data]

The average furnace repair cost in Houston is $323, and most service calls in the area end up costing between $117 and $572. Your price will depend mostly on the specific repair you need, although the type of furnace you have will also affect costs. Most homeowners in Houston use electric heat, and electric furnaces are more affordable to repair, so you can expect your costs to be a bit higher if you have a gas furnace.

Furnace Repair Cost Factors

Your furnace repair cost in Houston, TX, will depend on a few key factors, including the component that needs repair or replacement, add-on services you opt for, and labor costs. Be sure to consider all of these for the most accurate estimate possible.

Repair Cost by Part

Regardless of their fuel source, furnaces are complex appliances that have a lot of moving parts. Some of those parts significantly influence furnace repair costs, while others are simpler and less costly to repair.

Here is the average furnace repair cost based on the part:

Some of these components, including flame sensors, flue pipes, and gas valves, aren’t present on electric furnaces, and since close to 60% of homeowners in Houston use electricity as a fuel source for home heating, these charges won’t apply to most residents.

Maintenance Cost

A furnace requires regular maintenance in order to operate efficiently. Otherwise, dust and other debris can clog burners, the pilot light, and other parts, causing more wear and tear on the system. Since the winters are so mild in Houston, it’s easy to forget about your heating system, which can lead to premature failure, breakdowns, and inefficiencies. While you’re thinking about your system, it’s a good idea to schedule a formal inspection and sign up for ongoing maintenance.

A furnace inspection costs $80 to $100 on average, and you need to schedule an inspection at least once per year to keep your system running smoothly. An advanced inspection, which includes cleaning and a tuneup, costs $125 to $200. 

Additional maintenance costs include filters and air duct cleanings. You need to replace the filters once every 90 days, which will cost $4 to $140 per year. Schedule duct cleanings every three to five years, and expect to spend $275 to $500 for the cost of cleaning air ducts.

Cost per Hour

Furnace repairs cost $50 to $150 per hour for the labor, plus you’ll need to budget for the cost of parts. Small repairs may be billed at a $100 to $200 minimum rather than by the hour. 

One of the quickest repairs is to replace a dirty filter, which only takes a few minutes and is easy to DIY. Some of the more difficult, time-consuming parts to repair include the blower motor, the draft inducer motor, coils, and the heat exchanger.

HVAC Pro Costs

Between 40% and 90% of your total furnace repair cost will go toward labor, which means hiring an HVAC pro in Houston costs an average of between $130 and $290. On a per-hour basis, this is slightly below the national average, and this is thanks to the below-average cost of living in Houston driving down labor costs.

The City of Houston requires permits for any major HVAC repairs, and you’ll pay a flat fee of $46.35 plus 2% of the total repair cost in permit fees. For the average furnace repair in Houston, this comes out to a total of $52.81. However, you may not need permits for your repair, so ask your HVAC professional if you’ll need to budget for permits.

For a more accurate estimate, you should also consider sales tax, which your pro will have to charge on top of the primary repair cost. The sales tax rate in Houston is 8.25%, which means an average tax of $26.65 for the typical repair in the area.

Do Furnace Repairs Increase Home Value?

No, furnace repairs won’t increase your home value, but they can prevent your value from dropping. Buyers will expect a home’s mechanicals to be in good working order, and they’ll often offer less if they know of an existing issue they’ll need to fix post-closing.

If you find that replacing your furnace is a better option than repairing, then you can expect a bump in home value. Furnace replacement provides an average return on investment (ROI) of 30%, although you may see a lower return in areas like Houston, where the demand for heat is significantly lower than the demand for cooling.
