AC & Heating near Excelsior, San Francisco

What we work on

Full automotive AC and heating systems on every make and model. R-134a and the newer R-1234yf refrigerants both. We can test the system under pressure, find leaks with UV dye or an electronic sniffer, replace failed components, and recharge to the exact spec for your car.

• AC performance testing (vent temp, pressures, system check)
• Refrigerant leak diagnosis with UV dye or electronic detector
• AC recharge (R-134a and R-1234yf)
• Compressor, condenser, evaporator, and expansion valve replacement
• Heater core diagnosis and replacement
• Blower motor and resistor replacement
• AC blend door actuator replacement (the click-click-click sound)
• Cabin air filter replacement

Diagnose before recharge

A common scam in the AC business is to just recharge a leaking system and send the customer away. The refrigerant escapes again in weeks, the customer comes back, gets another recharge, and pays twice. We do not do that. If your system is low on refrigerant, it is leaking. We will find the leak first, give you an estimate to repair it, and then recharge. If you just want a top-off knowing it will leak again, we will tell you straight what we think and let you decide.

Heater problems

When the heater stops working, the usual suspects are a stuck thermostat, low coolant, an airlock in the cooling system, a clogged heater core, or a failed blower motor. We diagnose which one in under an hour most of the time. Heater core replacements are the bigger jobs — the whole dash usually has to come out — and we will give you a real estimate before you commit.

When to come in

AC blowing warm air, weak airflow even on max, a sweet smell from the vents (coolant leak from the heater core), water dripping inside the cabin, a clicking sound from behind the dash, or no heat after the engine warms up. All of those are AC or heating problems we can fix.
