Emergency HVAC Services in San Francisco, CA

A heating or cooling system doesn’t wait for a convenient time to fail. When your furnace goes out on a cold January night or your AC stops working during a summer heat wave in San Francisco, CA, you need a technician at your door fast, not a voicemail and a callback the next business day.

24-Hour HVAC Response from Same Day Air Conditioning & Heating

• Refrigerant leaks: Urgent diagnosis and repair of refrigerant issues that are causing your AC to lose cooling capacity or shut down entirely
• No heat or no cooling: Full system diagnostic when your HVAC isn’t producing heat or cool air, regardless of the underlying cause

• System shutdowns and electrical faults: Diagnosis of tripped breakers, failed capacitors, control board issues, and other electrical failures that leave your system unresponsive

When to Call for Emergency HVAC Service

Not every HVAC issue demands an emergency call, but some situations shouldn’t wait. In San Francisco, CA, these are the scenarios where calling immediately is the right move:

• Complete loss of heat in cold weather: Temperatures in San Francisco can drop into the 40s overnight, making a heating failure a genuine health and safety concern, particularly for young children, elderly residents, or anyone with health conditions
• Complete loss of cooling during a heat wave: Extreme heat events in the Bay Area can push indoor temperatures to dangerous levels without air conditioning, especially in upper-floor units and poorly insulated homes
• Yellow furnace flame or smell of gas: Either of these signals a potential combustion or carbon monoxide issue. Shut down the system, leave the space, and call immediately
• Water leaking from HVAC equipment: A flooding indoor unit or a boiler leak can cause structural damage quickly if not addressed
• Burning smell from vents or the unit: An electrical burning odor coming from your HVAC system is a potential fire hazard that warrants an immediate call
• Loud banging or grinding from the system: Sudden severe mechanical noises often indicate a component failure in progress that will worsen with continued operation

When in doubt, call. Our team can help you assess whether the situation needs urgent attention or can wait for a scheduled appointment.

What to Expect from Our Emergency Response

When you call Same Day for urgent HVAC repair in San Francisco, here’s how we handle it.

Fast Dispatch, Prepared Technicians

We dispatch a licensed technician to your home as quickly as possible. Our trucks are stocked with the most common replacement parts for both heating and cooling systems, which means most emergency repairs are resolved in a single visit rather than requiring a return trip once parts are sourced.

Honest Diagnosis Before Any Work Begins

Even in an emergency, our technicians don’t skip the diagnostic step. We inspect the full system to identify the root cause before recommending a repair, so you’re not paying to fix a symptom while the underlying problem remains. You’ll know exactly what’s wrong and what the repair will cost before we start.

Repair and Replacement Options on the Spot

If a diagnostic reveals that the system is beyond cost-effective repair, we won’t leave you without options. Our team handles both emergency AC repair and furnace repair on the same visit, and if replacement is the right call, our installation team can discuss next steps and get the project moving quickly.
