What to Check Before You Call
Before paying for an emergency visit, make sure the fix isn't something simple. These three checks take under five minutes:
- 1
Check your thermostat
Make sure it's set to "Cool" (or "Heat" in winter), the temperature is set correctly, and the batteries aren't dead. A blank thermostat screen often just means dead batteries.
- 2
Check your air filter
A clogged filter can cause weak airflow, ice on the coils, or a system shutdown. If it's gray and dusty, replace it and give the system 30–60 minutes to recover.
- 3
Check your electrical panel
Look for a tripped breaker labeled "AC," "Furnace," or "Air Handler." Reset it once. If it trips again, stop — that's an electrical problem that needs a technician.

Emergency HVAC Situations We Handle in South San Francisco
If your South San Francisco home is experiencing any of these, call us immediately — don't wait for business hours.
No Heat
South San Francisco winter nights can drop below 40°F. A heating failure is a health emergency, especially for families with young children or elderly residents. We prioritize no-heat calls above all others.
No Air Conditioning
Inland San Mateo & San Francisco Counties cities can reach 100°F+ during summer heat waves. AC failure during a PG&E heat advisory requires same-day service — don't delay.
Gas Smell from Furnace
Evacuate your South San Francisco home immediately, call PG&E at 1-800-743-5000 to shut off gas, then call us. Never run an HVAC system when you smell gas or burning.
Frozen AC or Heat Pump
Ice on your outdoor unit or evaporator coil means a refrigerant leak or airflow problem. Turn the system off (leave the fan on) and call us. Running a frozen system destroys the compressor.
Water Leaking from HVAC
A backed-up condensate drain or cracked heat exchanger can cause water damage to your South San Francisco home. Shut off the system at the thermostat and call us before the leak spreads.
System Not Responding
If your thermostat shows no response, your breaker keeps tripping, or the system won't start at all — these indicate electrical or control board failures that need immediate diagnosis.
