Failed compressor or a cheap capacitor?
The most expensive mix-up in residential HVAC.
If the fan is still and the can is swollen, start there. We measure. We do not condemn compressors from the driveway.
Many “dead compressors” are capacitors, contactors, or a breaker that trips on a failing fan motor.
The internet version of compressor vs capacitor is usually missing a meter reading. Ours is not.
We measure start and run current in context. A high LRA on a locked rotor is different from a dirty filter making a blower work harder.
We map compressor vs capacitor to the actual failed part or design limit. Age of the system is a data point, not the diagnosis.
You approve any repair after the findings are written down. Diagnostic visits are a flat $69. New installation estimates are free in-home with a load calculation — not a number invented from square footage on Zillow.
Replacing the compressor because amps “look high” without a capacitor test is a five-figure mistake.
A company that skips testing on compressor vs capacitor will skip it on the next call too. We would rather lose a job than install the wrong thing.

OTTER HVAC is based at 2939 Santos Ln, Walnut Creek. Clayton, Clayton, and Lafayette are regular routes, along with the rest of our listed East Bay cities. Hours are 7am–5pm, seven days a week. We do not advertise 24/7 because we do not staff a night shift.
Inland heat (Pleasanton, Livermore, Concord) and marine air (Alameda, Daly City) are different loads. A note written for Clayton is not automatically right for a fog-belt house. We treat them that way.

Frequently asked questions
What do you test on a compressor vs capacitor visit?
We measure start and run current in context. A high LRA on a locked rotor is different from a dirty filter making a blower work harder. The visit is a flat $69. Repair work starts only after you approve the written findings.
Will you quote compressor vs capacitor from a photo?
No. We do not price compressor vs capacitor from a driveway photo. $69 diagnostic, then a quote — or a free in-home install estimate if replacement is the honest path.
Do you handle this in Clayton and Clayton?
Yes. We run Clayton, Clayton, and the rest of our East Bay list from 2939 Santos Ln, Walnut Creek. Hours are 7am–5pm every day — not 24/7. Call (650) 900-0440.
