Our Heating Services in San Francisco, California
Furnace Repair
A furnace that stops working on a cold San Francisco evening creates immediate discomfort in a city where the damp marine air makes any drop in indoor temperature feel worse than the thermometer suggests. Furnace repair in San Francisco is one of the most common heating service calls our network receives during the fall and winter months, and many of these calls come from homeowners whose systems have been sitting dormant through the warmer months and reveal problems only when they’re turned on for the first time in the season. Same day furnace service in San Francisco is a consistent goal within our network for situations where a household is without heat.
Common Problems We Fix
- Furnace turns on but no warm air comes from the vents
- System ignites briefly and then shuts back off before completing a heating cycle
- Furnace not blowing hot air despite appearing to run normally
- Loud banging, rattling, or squealing sounds when the furnace operates
- Pilot light or electronic igniter failing to light consistently
- Burning smell from vents when the heat turns on for the first time in the season
- Heating cycling on and off rapidly without reaching the thermostat setpoint
- Some rooms receiving heat while others stay cold despite the furnace running
Furnace repair in San Francisco, California begins with a systematic diagnostic that covers the ignition system, the heat exchanger, the blower motor, the control board, and the thermostat communication before any parts are recommended. A furnace that short-cycles, for example, may have a clogged air filter causing overheating, a failing flame sensor, a pressure switch issue, or a control board fault, and these all require different repairs. The technician identifies the specific cause and explains it clearly before beginning any work. In San Francisco’s older homes in neighborhoods like the Excelsior and the Outer Mission, furnaces that have been in service for fifteen or more years may have multiple components approaching end of life simultaneously, and the technician will give you an honest assessment of repair versus replacement in that situation. If you smell gas or suspect a gas leak, go outside immediately and call 911 – this is a serious emergency that needs urgent attention from the gas company.
Furnace Installation
Furnace installation in San Francisco is needed when an existing furnace has failed beyond repair, when a home is upgrading from an old low-efficiency unit to a modern high-efficiency system, or when a property is being converted from another heating type to forced-air gas heat. Replace old furnace decisions in San Francisco should involve an honest comparison of continued repair investment versus the cost and performance benefits of a new system, and the professionals in our network provide that comparison honestly rather than defaulting to replacement as the automatic answer.
Common Reasons Homeowners Choose Installation
- Existing furnace is more than fifteen to twenty years old and major components are failing
- Heating bills have risen significantly despite no change in usage patterns
- Furnace has required multiple repairs in the past two years
- Heat exchanger has cracked, making the current unit unsafe to continue operating
- High efficiency furnace upgrade in San Francisco motivated by long-term energy savings
- Home renovation creating the opportunity to install a properly sized new system
- Converting from oil or electric resistance heating to gas forced-air heat
- New home purchase where the existing furnace is at end of life
Furnace installation in San Francisco involves proper sizing of the new unit based on the square footage, insulation level, and heat loss characteristics of the specific home, not just matching the tonnage of the old unit. An improperly sized furnace, whether too large or too small, creates performance problems and reduced system life from day one. The installation includes proper venting for the specific furnace type, gas line connection with pressure testing, thermostat wiring, and a full system commissioning sequence to confirm the new furnace operates correctly before the technician leaves. High efficiency furnace upgrade options in San Francisco, where two-stage and modulating furnaces provide more precise temperature control and quieter operation than older single-stage units, are explained during the installation consultation.
Boiler Repair and Installation
San Francisco has a significant inventory of older buildings, particularly in Nob Hill, Pacific Heights, Russian Hill, and similar established neighborhoods, that use boiler-based hydronic heating. These systems heat homes through radiant floor piping or baseboard radiators and are known for efficient, even, quiet heat when they’re properly maintained. Boiler repair in San Francisco, California is a specialized service that requires technicians familiar with hydronic systems, pressure management, expansion tank function, zone valves, and the specific components that keep a boiler system in balance.
Common Problems We Fix
- Boiler pressure dropping repeatedly and needing manual repressurization
- Radiators staying cold even after the boiler has been running for an extended period
- Banging or knocking sounds inside the boiler or traveling through the pipes
- Water dripping from the boiler body or from pipe connections near the unit
- Boiler leaking in an older San Francisco home where the unit has been running for decades
- Pilot light going out repeatedly on an older gas boiler
- Fix boiler not heating situations where the unit fires but heat doesn’t reach the radiators
- Zone valve failure causing certain areas of the home to receive no heat
Boiler repair in San Francisco addresses the full range of component issues, from pressure relief valve replacement and expansion tank recharging to circulation pump repair, zone valve replacement, and heat exchanger assessment. Boiler leaking in older home situations in San Francisco are common in the city’s pre-1970 residential buildings where original boiler units may still be in service decades past their designed service life. Boiler installation in San Francisco for a replacement follows a full system assessment including the condition of the existing distribution piping, radiators, and zone controls, so the new boiler is properly matched to the existing system. The installation is pressure-tested completely before the system is returned to service.
Heat Pump Installation and Repair
Heat pump installation in San Francisco, California has become an increasingly popular choice as homeowners look for heating and cooling systems that provide both functions efficiently in the city’s mild climate. San Francisco’s temperature range is actually well-suited to heat pump technology. Heat pumps extract warmth from the outdoor air and transfer it inside for heating, a process that is highly efficient in climates where outdoor temperatures rarely drop below freezing. In San Francisco, where heating-season temperatures stay well above zero most nights, a heat pump delivers heating performance that rivals gas systems at a fraction of the operating energy consumption.
Common Problems We Fix
- Heat pump not providing adequate warmth during cooler San Francisco nights
- System blowing cool or lukewarm air in heating mode
- No heat in house situations where the heat pump has stopped functioning entirely
- Heat pump maintenance overdue, resulting in declining efficiency and performance
- Outdoor unit icing up and not entering defrost cycle correctly
- System switching between heating and cooling mode unexpectedly
- Heat pump running continuously without reaching the set temperature
- Unusual sounds from the outdoor unit during operation
Heat pump repair near me in San Francisco situations are diagnosed with the same thoroughness as any other HVAC service: full electrical inspection, refrigerant charge verification, coil cleaning, defrost control assessment, and reversing valve function testing. Heat pump maintenance in San Francisco on an annual schedule is particularly important for maintaining efficiency and extending system life, as a heat pump in this climate may run in both heating and cooling modes through different seasons. New heat pump installation in San Francisco begins with a proper load calculation and an honest comparison with other heating options, so the homeowner can make the decision that’s right for their specific home, energy goals, and budget.
Why San Francisco Homeowners Choose San Francisco Plumbing and Air Pros
Local Focus in San Francisco, California and the Surrounding Bay Area
Heating in San Francisco is a different conversation than heating in Chicago or Denver. The city’s climate is mild but damp, the housing stock skews old, and the mix of heating systems, from hydronic boilers in Nob Hill apartment buildings to gas forced-air in Sunset District bungalows to heat pumps in newly renovated Mission District flats, requires technicians who are familiar with the full range of what San Francisco homes actually use. The professionals in our network know the city’s heating landscape and arrive prepared for what they’ll find.
Meticulous Diagnostics and Fixing the Root Cause
A furnace that short-cycles can have a dozen different causes, and replacing the most frequently failed part without running a proper diagnostic often results in the repair failing to resolve the problem. The technicians in our network run complete system diagnostics, identify the actual root cause of the heating failure, and address it directly. If the issue is a failing heat exchanger rather than a simple igniter, they tell you honestly, because a cracked heat exchanger is a safety concern that needs to be understood clearly by the homeowner.
Respect for Your Home, Clean Work Habits, and Clear Communication
Furnace and boiler work in San Francisco homes often involves accessing equipment in utility closets, basements, or mechanical rooms that are in daily use. The professionals we connect you with work efficiently, protect the areas surrounding the equipment during service, and leave the space clean when they’re done. They explain every finding in plain language, walk you through the repair or installation, and answer questions directly before, during, and after the work. No surprises, no pressure, no vague explanations about what was done.
Skilled with Modern Furnaces, Boilers, and Heat Pumps
San Francisco’s heating landscape requires technicians who are comfortable with a wide range of system types, from original cast iron boilers in Victorian apartment buildings to modern two-stage high-efficiency furnaces in renovated homes and inverter-driven heat pumps in newer construction. The professionals we connect you with have current working knowledge of all of these system types, including the electronic control systems and diagnostic interfaces that modern equipment uses. This breadth of expertise means you’re connected with someone who can handle whatever your San Francisco home’s heating system turns out to be.

3. Diagnosis and Clear Explanation
The technician performs a complete assessment of the heating system on arrival, testing every relevant component before drawing any conclusions. The diagnosis is explained clearly before any repair work begins, including what was found, what needs to be done, and why. You understand exactly what you’re agreeing to before the technician picks up a tool. If gas is involved in any way and there is a safety concern, that is communicated clearly and immediately.
4. Repair and Final Checks
The repair or installation is completed correctly, with quality parts and proper technique. After the work is finished, the technician runs the heating system through a full cycle to confirm it’s operating correctly, checks all safety controls, verifies proper airflow or heat distribution depending on the system type, and confirms there are no secondary issues before leaving your San Francisco home.
Service Area in and Around San Francisco, California
We connect homeowners throughout all of San Francisco with qualified heating professionals who know the city’s neighborhoods, building types, and heating system configurations. From Victorian apartment buildings in Pacific Heights and Russian Hill to single-family homes in the Sunset and West Portal to condos in SOMA and Mission Bay, our network covers the full city and extends into surrounding communities.
- Richmond District
- Sunset District
- Pacific Heights and Cow Hollow
- Mission District

- Russian Hill and Nob Hill
- Haight-Ashbury
- SOMA and Mission Bay

True local heating service in San Francisco means a technician who knows that a Nob Hill building from 1925 likely has a hydronic boiler system, that a West Portal bungalow from 1955 is probably running a gas furnace with original ductwork, and that a new Mission District renovation may have a heat pump for both heating and cooling. That building-type knowledge makes diagnoses faster and recommendations more relevant to the actual system in front of the technician. It’s what the professionals in our network bring to every San Francisco heating call.
Professional Heating Repair vs DIY Attempts
Heating system repair in San Francisco is an area where the risks of DIY work are substantial enough that even experienced home improvement enthusiasts should recognize the boundaries between what they can safely do and what requires professional involvement.
Gas-fired furnaces and boilers involve active gas connections and combustion systems. Any work on the gas supply line, the gas valve, the burner assembly, or the heat exchanger must be performed by a professional who has the proper tools for gas pressure testing and who understands the safety sequence for restoring a gas appliance to service after repairs. If you smell gas or suspect a gas leak, go outside immediately and call 911 – this is a serious emergency that needs urgent attention from the gas company. Even after the gas company has addressed an active leak, the repair or replacement of the gas components on the appliance itself requires professional service.
Heat exchangers in gas furnaces are particularly important from a safety perspective. A cracked heat exchanger allows combustion gases, including carbon monoxide, to mix with the air circulating through the home’s ductwork. This creates a serious health hazard that develops slowly and invisibly. Diagnosing heat exchanger cracks requires visual inspection under proper lighting and sometimes combustion analysis equipment, and this is not a DIY assessment. A homeowner who attempts to continue operating a furnace with a suspected cracked heat exchanger is taking a genuine risk with their household’s safety.
Boiler systems operate under pressure with high-temperature water circulating through the system. Work on pressure relief valves, expansion tanks, and circulating pumps should be done only by someone who understands hydronic system pressure management. An improperly set or incorrectly installed pressure relief valve on a boiler is a safety device failure waiting to happen. Expansion tanks that are replaced without proper pre-charging create pressure cycling problems that accelerate wear on the boiler and its connections.
Heat pump systems have electrical components operating at line voltages and refrigerant circuits that require professional handling. The reversing valve that switches a heat pump between heating and cooling modes is a precision component that requires specialized tools to test and replace. Refrigerant work on a heat pump requires professional equipment for recovery, recharge, and leak testing.
For San Francisco homeowners with older boiler systems in historic buildings, there is an additional consideration. Original hydronic piping in buildings from the early 20th century may be in a fragile condition, and disturbing connections without understanding the pipe material and condition can create new leaks during what was intended to be a different repair. A professional who has worked in these buildings recognizes the signs of aging pipe infrastructure and works carefully around it. Contact us today and we will connect you with a qualified San Francisco heating professional who handles every system type correctly.

Same day heating repair in San Francisco?
Yes. Same day heating service in San Francisco is the operational goal for no-heat emergencies through our network. We match you with the nearest available qualified heating technician based on your San Francisco location and the urgency of the situation. For heating failures during cold weather, same day response is prioritized above all other scheduling. Contact us today as soon as a heating failure becomes apparent, and the earlier in the day you reach out, the better the chances of same day service for your specific location in the city.
How soon can you come for heating service?
For no-heat emergencies in San Francisco, we work to connect you with a technician the same day. For standard repairs and maintenance visits, scheduling within one to two business days is typically achievable. During the start of heating season, when many San Francisco homeowners turn their furnaces on for the first time in months and discover problems simultaneously, demand spikes and same day availability for non-emergency calls may be limited. Proactive fall maintenance visits are worth scheduling early to avoid the seasonal rush.
Do you work on older homes in San Francisco?
Absolutely. Heating service in older San Francisco homes is the most common context our network operates in. Whether it’s a hydronic boiler system in a Victorian Pacific Heights apartment building, an aging gas furnace in a Richmond District flat, or a heat pump installation in a Mid-Century property, the professionals we connect you with are experienced with the full range of heating systems and building configurations present in San Francisco’s older housing stock. Older homes are the everyday normal for our network, not an exception.

Reach out to us for assistance and we will connect you right away.
Do you install heat pumps?
Yes. Heat pump installation in San Francisco, California is a growing part of our network’s work as more homeowners look for systems that provide both efficient heating and cooling. We connect you with professionals who assess your home’s specific characteristics, size the system properly, and handle the full installation from electrical service to refrigerant commissioning. For San Francisco’s mild climate, heat pump technology is particularly well-suited, and the professionals we connect you with can explain the comparison with gas heating honestly based on your home’s specific configuration and your energy goals.
Why is my furnace not blowing hot air?
How to fix no heat from vents in a San Francisco home starts with understanding which component has failed. Common causes include a flame sensor that has become coated with residue and no longer reliably detects the burner flame, causing the gas valve to shut off quickly after ignition. A failed capacitor on the blower motor allows the heat exchanger to get hot but prevents the fan from distributing the warm air. A clogged air filter restricts airflow severely enough to trigger a high-limit safety shutoff. A control board fault disrupts the normal ignition sequence. Each requires a different repair, which is why a proper diagnostic comes before any parts recommendation.
What should I do before the technician arrives?
Check the thermostat to confirm it’s set to heat and the temperature setting is above the current room temperature. Replace the air filter if you know it hasn’t been changed recently. Check the circuit breaker panel for the furnace to confirm it hasn’t tripped. If you have a gas furnace or boiler, confirm the gas supply is on at the main shutoff. Clear access to the furnace or boiler equipment and the thermostat. If you smell gas at any point, leave the building immediately and call 911 rather than proceeding with any of the above steps. Note any unusual sounds, smells, or behaviors the system showed before it stopped working and share that with the technician when they arrive.
How often should I service my furnace or boiler?
Annual heating system maintenance is the standard recommendation, and in San Francisco the best time is typically in the fall before the heating season begins. Annual service for a gas furnace includes cleaning the burner assembly, testing the igniter and flame sensor, inspecting the heat exchanger, checking the blower motor, lubricating moving parts, and verifying all safety controls are functioning correctly. For a boiler, annual service includes checking the pressure, testing the expansion tank, inspecting the heat exchanger and burner, and verifying zone controls. Consistent maintenance prevents most mid-season failures and extends the service life of the equipment significantly.
We are San Francisco Plumbing and Air Pros, your local heating services connection for every furnace, boiler, and heat pump need across San Francisco, California.
