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

Furnace repair costs in San Francisco are $504 on average, with most homeowners here spending from $178 to $866, depending on the furnace type and what needs to be repaired. San Francisco is known for long stretches of cool, cloudy weather, so a working furnace is a must for keeping warm in this environment.

Furnace Repair Cost Factors 

Furnace repair costs in San Francisco, CA, depend on a number of different factors, like the type of furnace part that needs replacing and regular maintenance tasks.

Repair Cost by Part

Regardless of their fuel source, furnaces are complex appliances that have a lot of working 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:

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. 

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 start at $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

The best person to hire for furnace repair is an HVAC repair specialist in San Francisco, CA. These pros are specially trained to work with varying types of furnaces, ranging from natural gas to electric to radiators. Hiring an HVAC pro in a high-cost-of-living city like San Francisco will cost more, around $80 to $200 per hour, compared to smaller cities or rural areas. Plus, expect to spend about $100 to $200 for the initial service fee.

Do Furnace Repairs Increase Home Value?

Furnace repairs offer a slight increase in home value by ensuring the HVAC system is running efficiently. However, if your furnace is over 15 years old, you’ll get a better return on investment (ROI) by replacing instead of repairing the system, which can increase home value by 5% to 7%. However, if your system is younger, making repairs and keeping up with furnace maintenance is a great way to keep your home comfortable for the current and future residents.
