We check static pressure and return airflow alongside the condenser and coils.
Zoned systems, single-stage, and two-stage units are all within scope.
If you're dealing with one room that never cools evenly, a system that runs constantly without ever hitting the set temperature, or a total shutdown mid-August, you already know central air complaints are frequently misdiagnosed as a simple refrigerant top-off when the real cause is airflow, ductwork, or a failing zone damper.

Most air conditioning repair problems give some warning before they turn into one room that never cools evenly, a system that runs constantly without ever hitting the set temperature, or a total shutdown mid-August — catching it early usually means a shorter, cheaper fix.
Our technicians treat every air conditioning repair call in Greenbrae, CA the same way, whether it's a straightforward fix or a stubborn intermittent fault that two other companies already missed.
We're licensed, insured, and staffed with techs who've spent years specifically on air conditioning repair, not general handyman work with an HVAC certificate bolted on.

We evaluate condenser, coils, ductwork, and airflow together instead of assuming the outdoor unit is always the culprit.
Trucks are positioned regionally to keep response windows realistic.
Diagnosis and labor are quoted together before any work starts.
A system that's 'low on freon' repeatedly is often actually restricted on the air side.
Every job starts with a real diagnosis, not a guess — here's the full scope of what our air conditioning repair technicians handle across Greenbrae, CA.
Outdoor unit diagnostics cover compressor, fan motor, contactor, and capacitor together. Techs handling central air condenser repair carry the specific parts and tools this job calls for, not a generic kit.
We test each zone's damper motor individually rather than assuming the whole system is at fault. Techs handling zone damper & control repair carry the specific parts and tools this job calls for, not a generic kit.
Coil access panels get inspected properly, not just glanced at. This is one of the most requested air conditioning repair calls we get across Greenbrae, CA.
Uneven room-to-room cooling frequently traces to duct leaks, disconnected runs, or undersized returns. Techs handling ductwork airflow diagnosis carry the specific parts and tools this job calls for, not a generic kit.
We pull manufacturer-specific fault codes on these systems rather than guessing. This is one of the most requested air conditioning repair calls we get across Greenbrae, CA.
A zoning control panel that's miscommunicating with dampers can mimic a full mechanical failure. This is one of the most requested air conditioning repair calls we get across Greenbrae, CA.

Describe whether it's total failure, uneven cooling, or constant running without reaching temperature.
We confirm your Greenbrae address and give a realistic arrival window.
Full system check — condenser, coils, ductwork, zoning — before any single component gets blamed.
Most airflow and component repairs finish in one visit.

Upstairs bedroom never cooled below 78 no matter what we set the thermostat to.
Two other companies just wanted to add refrigerant every summer.
Tech pulled the fault code and traced it to a bad pressure switch.
Whole system died on the hottest day of the year.

We test airflow at the affected register before assuming anything about the outdoor unit.
This pattern often points to restricted airflow, an undersized system for the space, or a refrigerant issue — a full diagnostic separates the three.
Yes — damper motors, zoning control panels, and the wiring between them are all within scope.
We check airflow as a standard part of central air diagnostics.
Central systems involve ductwork, zoning, and a much larger air-handling path, so diagnostics go beyond the outdoor unit alone.
Total outages during extreme heat get priority routing across Greenbrae, CA.
