We check static pressure and return airflow alongside the condenser and coils.
One diagnostic visit, one flat-rate quote, no push toward an unnecessary full-system replacement.
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 Cotati, 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.
You get a repair quote first — replacement is discussed only when the numbers genuinely favor it.
Manometers and airflow hoods confirm whether the problem is refrigerant, ductwork, or a failing blower.
From the first symptom to the final fix, these are the specific air conditioning repair services our Cotati-area crews are equipped for.
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.

Coil access panels get inspected properly, not just glanced at. Techs handling evaporator coil service carry the specific parts and tools this job calls for, not a generic kit.
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 Cotati, 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 Cotati, CA.

That detail shapes which diagnostic tools ride along on the truck.
We confirm your Cotati address and give a realistic arrival window.
Full system check — condenser, coils, ductwork, zoning — before any single component gets blamed.
Workmanship is guaranteed and documented on your invoice.

Upstairs bedroom never cooled below 78 no matter what we set the thermostat to.
This tech found a duct leak in the attic with a static pressure test and it fixed the recurring problem for good.
Two-stage system kept locking into low stage and never fully cooling.
Whole system died on the hottest day of the year.

We test airflow at the affected register before assuming anything about the outdoor unit.
Constant running without recovery is not normal and shouldn't be ignored.
Yes — damper motors, zoning control panels, and the wiring between them are all within scope.
Absolutely — a large share of 'weak cooling' complaints trace back to duct leaks or undersized returns, not the condenser.
Central systems involve ductwork, zoning, and a much larger air-handling path, so diagnostics go beyond the outdoor unit alone.
