Most Emergency Ac Repair emergencies in Greenbrae, CA gave some warning first, even if it was easy to dismiss at the time.
A system that runs but never actually cools usually means a refrigerant charge issue, a failing capacitor, or restricted airflow — not something a thermostat adjustment will fix. Ignoring warm air from the vents rarely makes the underlying issue cheaper to fix later.
A furnace that clicks but never lights, or one that lights and shuts off within seconds, usually points to a failing ignitor, a fouled flame sensor, or a safety switch doing exactly its job. Ignoring furnace won't ignite or keeps shutting off rarely makes the underlying issue cheaper to fix later.
A system working harder than it should to hit the same setpoint is a system with a developing problem, even if it hasn't fully failed yet. Our Greenbrae, CA techs see this specific pattern often enough to diagnose it quickly rather than guess.
A grinding or squealing sound usually points to a motor bearing wearing out; a banging sound during startup often means a loose or broken internal component. Our Greenbrae, CA techs see this specific pattern often enough to diagnose it quickly rather than guess.
One room that's always too warm or too cold while the rest of the house is fine usually traces to a duct, damper, or airflow issue rather than the system itself. Ignoring uneven temperatures room to room rarely makes the underlying issue cheaper to fix later.
Turning on and off every few minutes instead of running a full cycle strains the compressor and rarely resolves itself. Ignoring system short-cycling rarely makes the underlying issue cheaper to fix later.

From a condenser that won't start to a full central air replacement, our Greenbrae, CA AC technicians handle refrigerant leaks, compressor diagnostics, capacitor failures, and complete system installs. Refrigerant leak detection uses electronic detectors and UV dye, not a repeated top-off that never addresses the actual leak. Techs handling ac repair & installation carry the specific parts and tools this job calls for, not a generic kit.
Gas and electric furnace repair, heat pump service, and full heating system installation are all within scope for our Greenbrae, CA technicians. Heat pump-specific diagnostics cover the reversing valve and defrost cycle, components that a generalist unfamiliar with heat pumps can easily misdiagnose. Techs handling heating & furnace services carry the specific parts and tools this job calls for, not a generic kit.
Leaky, disconnected, or undersized ductwork can waste a significant share of a system's output before it ever reaches a vent — we test static pressure and duct leakage rather than sealing blind. Mastic sealing, not just tape, on any duct joint we repair, since tape degrades in attic heat within a couple of seasons.
