A Local Guide to HVAC Service in San Francisco, CA
Living in San Francisco means enjoying iconic fog, mild summers, and surprisingly chilly winters. But when your furnace gives out during a damp, cold snap in the Sunset District or your AC fails during a rare heatwave in SoMa, comfort becomes an urgent need. This guide covers everything you need to know about HVAC service in San Francisco, CA—from routine maintenance to 24/7 emergency repairs—so you’re prepared for whatever our unique climate throws your way.
What Full-Scope HVAC Service Means for San Francisco Homes
HVAC service in San Francisco isn’t just a single task; it’s complete care for your home’s heating and cooling system. For local homeowners, this includes seasonal tune-ups before our foggy summer or our wet winter, same-day repairs for sudden issues, and of course, 24/7 emergency response for true safety crises. Think of it as a partnership to keep your Noe Valley Victorian warm or your Mission District condo’s air clean and cool year-round.
What Really Counts as an HVAC Emergency?
Not every HVAC problem needs a midnight call. But some situations are true emergencies. If you have no heat during freezing overnight temperatures in Potrero Hill, that’s an emergency. If your AC fails completely during a dangerous heatwave, that’s an emergency. Most urgent are safety threats: the smell of natural gas from your furnace, your carbon monoxide alarm sounding, visible smoke or burning smells from the unit, or a major water leak from your AC flooding a room. In these cases, don’t wait.
How San Francisco’s Climate Stresses Your System
Our coastal climate is gentle but presents specific challenges. Salt air from the bay can corrode outdoor AC units and heat pumps. Our famous humidity encourages mold and clogged drain lines. Older homes in neighborhoods like Haight-Ashbury or the Marina often have aging furnaces or boilers that struggle with efficiency, while newer constructions in Dogpatch might use modern heat pumps. Whether it’s a central AC, a gas furnace, or a ductless mini-split, the salt, moisture, and temperature swings mean your system needs knowledgeable, local HVAC service.
Common HVAC Problems We See in San Francisco
Local technicians stay busy with a few repeat issues. AC not cooling enough on hot days is common, often due to dirty coils or failing capacitors. Furnaces in older Richmond District homes may have ignition problems when winter hits. A frequent call we get is for AC units leaking water inside—this is usually a clogged condensate line from our humid air. Another local story: a homeowner in Bernal Heights heard strange banging; it was a loose blower wheel in an old furnace, a simple fix that prevented major damage. We also see carbon monoxide risks from poorly vented, aging equipment, which is why regular checks are so vital.
Emergency HVAC vs. Same-Day vs. Routine Service
Knowing when to call can save you stress and money. Call for emergency HVAC service in San Francisco immediately for safety issues (gas smells, CO alarms) or total comfort loss during extreme weather. For problems like weak airflow or a thermostat acting up on a mild day, same-day HVAC service is a great option. And for annual check-ups or minor, non-urgent noises, scheduling routine HVAC service near me during business hours is perfectly fine. This full spectrum is what comprehensive HVAC service is all about.
Understanding HVAC Service Costs in San Francisco
Being transparent about costs builds trust. Most local HVAC services include a standard diagnostic fee, typically between $75 and $150, to pinpoint the problem. For true emergency or after-hours calls, there is often an emergency call-out fee, which can range from $100 to $250. Labor rates during these times may be 1.5 to 2 times the standard hourly rate, which in San Francisco generally falls between $90 and $150 per hour. Parts are additional. For example, a common after-hours fix for a failed capacitor causing no AC might cost $250-$450 total, while a more complex furnace ignition repair on a weekend could be $400-$700. Major replacements require permits per local codes and have higher project costs.
Signs You Need Immediate HVAC Service
- No heat during freezing or wet winter weather.
- Your carbon monoxide alarm is sounding.
- You smell a strong odor of natural gas.
- There’s smoke or a burning electrical smell from the unit.
- Water is pooling from your indoor AC unit.
- You hear loud banging, screeching, or buzzing noises.
- Your AC has completely failed during a period of dangerous heat.
Safety Checklist While You Wait for Help
- If you smell gas, evacuate immediately and call your gas utility from outside.
- If the CO alarm sounds, get everyone outside to fresh air.
- If it is safe to do so, shut off the HVAC system at the thermostat or circuit breaker.
- Keep away from any electrical components that are sparking or smoking.
- Move children, elderly family members, or pets to a safe, comfortable location.
- Never attempt to repair gas lines or high-voltage electrical components yourself.
Local Codes, Permits, and Why Licensing Matters
In San Francisco, proper HVAC work must follow strict codes. This includes correct furnace venting to prevent CO poisoning, EPA 608 certification for handling refrigerants, and permits for any major system replacement. Hiring a licensed professional for your HVAC service ensures the work is safe, efficient, and compliant, protecting your home and family.

When you call for emergency service, a local team will typically be dispatched within 60 to 120 minutes. Response can vary based on traffic on the 101 or I-280, severe weather, and how many calls are coming in from across the city. We work to get to you in the Bay Area as fast as safely possible.
