Heating Services in San Francisco, CA

San Francisco’s mild but persistently cool and foggy climate means heating systems work harder than most Bay Area cities. Fog-belt neighborhoods like the Outer Sunset, Outer Richmond, and Daly City border see temperatures that rarely break 65°F even in summer. A reliable heating system isn’t optional in SF — it’s essential year-round.

San Francisco Heating Maintenance

Annual heating maintenance is the single best way to avoid mid-winter breakdowns. Our HVAC service experts inspect heat exchangers, test ignition systems, check gas pressure, clean burners, and verify that your system is running safely and efficiently. SF’s salt air and fog accelerate corrosion on heat exchangers — an annual inspection catches these issues before they become dangerous.

San Francisco Heating Repair

From floor furnaces in pre-war flats to modern forced-air systems in newer construction, we repair every heating system type found in San Francisco homes. Common SF heating repairs include failed ignitors, cracked heat exchangers, faulty thermostats, and blower motor failures. We carry parts for all major brands and complete most repairs on the same visit.

San Francisco Heating Installation

When your heating system is past its useful life, we help you select and install the right replacement for your home’s layout, ductwork situation, and budget. For SF homes without existing ductwork — which is the majority of Victorian and Edwardian flats — ductless mini-split heat pumps are often the best solution. We handle permits, installation, and startup.

Air Conditioning Services in San Francisco, CA

Most San Francisco homes were built without central air conditioning — the city’s famously mild summers made it unnecessary for decades. But climate patterns have shifted, and summer heat events now regularly push SF temperatures into the 80s and 90s. More homeowners are adding cooling for the first time, and ductless mini-split systems are by far the most practical solution for SF’s older housing stock.

San Francisco AC Installation

Installing air conditioning in an older SF home requires expertise. Most Victorian and Edwardian flats have no ductwork — making traditional central AC impractical without major construction. Ductless mini-split systems solve this elegantly: one outdoor unit, one or more indoor air handlers mounted on walls, no ductwork required. We size, permit, and install the right system for your home.

San Francisco AC Repair

SF’s salt air and coastal moisture are hard on AC equipment — particularly outdoor condenser units. Corrosion on coils and electrical components is more common near the coast than inland. Our service experts inspect and repair all AC system types, and we stock parts for all major brands to complete most repairs same-day.

San Francisco Ductless Mini-Split Services

Ductless mini-split systems are the ideal HVAC solution for San Francisco’s older homes. They provide both heating and cooling in a single system, require no ductwork, offer room-by-room temperature control, and qualify for California energy rebates. We install and service all major brands including Mitsubishi, Daikin, LG, and Fujitsu throughout SF.

Air Quality Services in San Francisco, CA

Common HVAC Issues in San Francisco Homes

San Francisco’s unique combination of old housing stock, coastal climate, and dense urban environment creates a specific set of HVAC challenges our service experts deal with every day:

• No ductwork in Victorians and Edwardians — The majority of SF’s pre-1940 housing was never built with forced-air systems. Wall heaters, floor furnaces, and radiant heat are the norm. Ductless mini-splits are now the most practical way to add both heating efficiency and cooling to these homes.
• Floor furnace failures — Floor furnaces are common in older SF flats and are frequently neglected. When they fail — often from cracked heat exchangers or failed thermocouples — they can be dangerous. We repair and replace floor furnaces throughout the city.
• Coastal corrosion on HVAC equipment — Salt air and persistent fog accelerate corrosion on heat exchangers, condenser coils, and electrical components. Fog-belt neighborhoods see this faster than the rest of the city. Annual inspection catches corrosion before it becomes a safety issue.
• Undersized heating systems — Many SF homes have wall heaters or floor furnaces that were adequate for one unit but can’t keep up with modern usage. Upgrading to a properly sized system — or adding a mini-split — dramatically improves comfort.
• Increasing demand for cooling — SF’s summer heat events are becoming more frequent and intense. Homes that never needed AC before now regularly see indoor temperatures in the mid-80s during heat waves. Mini-splits are the most practical first-time cooling solution for SF’s older housing stock.

My SF home has no ductwork — what are my options for heating and cooling?

Ductless mini-split systems are the best solution for SF’s older homes without ductwork. One outdoor unit powers one or more indoor air handlers mounted on walls or ceilings — no duct installation required.

Do you work on floor furnaces and wall heaters?

Yes — floor furnaces and wall heaters are some of the most common heating calls we get in San Francisco. We repair and replace both types throughout the city. If your floor furnace has a cracked heat exchanger or your wall heater won’t ignite, call us — these are safety issues that need prompt attention.
