Our furnace repair services cover every aspect of your heating system. We repair gas furnaces, electric furnaces, and heat pumps, handling everything from simple thermostat issues to complex heat exchanger problems.
In San Francisco County, we frequently address issues specific to our climate and housing stock. Many older homes have aging ductwork that affects efficiency, while newer constructions sometimes have installation issues that impact performance. We’re experienced with both scenarios and the unique challenges they present.
Our service includes emergency repairs when your system fails unexpectedly, routine maintenance to prevent breakdowns, and efficiency upgrades that can significantly reduce your energy costs. We work with all major furnace brands and carry quality replacement parts, so we can usually complete repairs in a single visit. Every repair comes with our warranty and satisfaction guarantee.
Furnace repair costs in San Francisco County typically range from $178 to $866, with an average of around $504. The final cost depends on what’s wrong with your system, which parts need replacement, and how complex the repair is.
Simple fixes like replacing a thermostat or cleaning a dirty filter cost less, while major repairs like replacing a heat exchanger or blower motor cost more. We always provide upfront pricing before starting any work, so you’ll know exactly what you’re paying with no surprise fees.
Our goal is to give you the most cost-effective solution for your situation. Sometimes that means repairing your current system, and sometimes it means recommending replacement if your furnace is old and likely to need frequent repairs.
In San Francisco County, we see several common furnace issues related to our unique climate and housing characteristics. Dirty air filters are extremely common because of the fog and moisture in the air, which can clog filters faster than in drier climates.
Pilot light problems occur frequently in older gas furnaces, especially when they haven’t been maintained regularly. We also see issues with thermostats that aren’t calibrated correctly for San Francisco’s temperature fluctuations, and ductwork problems in older homes that affect airflow and efficiency.
Corrosion and moisture-related issues are more prevalent here due to our coastal location. Regular maintenance helps prevent most of these problems, but when they do occur, our technicians have the experience to diagnose and fix them quickly.
We understand that furnace emergencies can’t wait, especially during San Francisco’s cold spells. We offer same-day service for emergency repairs and prioritize calls where customers have no heat at all.
Our goal is to respond to emergency calls within a few hours during business hours. For after-hours emergencies, we have technicians available to handle urgent situations that can’t wait until the next business day. We keep common repair parts stocked in our service vehicles, so we can often complete emergency repairs immediately.
When we can’t fix your furnace the same day, we’ll work with you to find temporary solutions and schedule the earliest possible appointment to complete the repair. We know how important your home’s heating is, especially in San Francisco’s unpredictable weather.
Yes, we service and repair all types of residential heating systems commonly found in San Francisco County homes. This includes natural gas furnaces, electric furnaces, heat pumps, and older radiator systems that are still common in many San Francisco neighborhoods.
We work with all major furnace brands including Carrier, Trane, Lennox, Rheem, Goodman, and many others. Our technicians are trained on both newer high-efficiency systems and older equipment that’s still functioning in many Bay Area homes.
Whether you have a standard furnace, a high-efficiency condensing unit, or a ductless mini-split system, we have the expertise and tools to diagnose problems and make repairs. We also service the ductwork and ventilation components that are part of your complete heating system.
If your furnace stops working completely, start by checking a few simple things before calling for service. Make sure your thermostat is set to “heat” and the temperature is set higher than the current room temperature. Check that your circuit breaker hasn’t tripped and that your furnace switch is in the “on” position.
Look at your air filter—if it’s extremely dirty or clogged, replace it and see if that resolves the issue. For gas furnaces, check if the pilot light is lit, but don’t attempt to relight it yourself if you smell gas.
If these basic checks don’t solve the problem, call us immediately. Complete furnace failure often indicates a serious issue that requires professional diagnosis and repair. We’ll prioritize your call and get a technician to your home as quickly as possible to restore heat to your house.
In San Francisco County, we recommend annual furnace maintenance, ideally in the fall before you start using your heating system regularly. Our coastal climate creates unique conditions that can affect your furnace’s performance and longevity.
The moisture in our air can cause corrosion and affect electrical components, while the dust and particles that come with our fog can clog filters and components more quickly than in other climates. Regular maintenance helps prevent these issues and keeps your system running efficiently.
During a maintenance visit, we clean and inspect all components, test safety systems, check gas connections, and replace your air filter. This preventive approach helps avoid emergency breakdowns and extends your furnace’s lifespan. Most manufacturers also require regular maintenance to keep warranties valid, so annual service protects your investment too.
