Second opinion on an HVAC replacement
Bring the other quote. We will test, not just undercut.
If another company condemned the heat exchanger, we look at the exchanger — not at how to steal the job.
Technical language can be used to make a $12 part sound like a failed compressor. Readings need context.
Use this as a field guide to HVAC second opinion, then book a visit if the house still misbehaves.
We document findings. If a capacitor, contactor, or flame sensor is the issue, that is what we quote.
We map HVAC second opinion 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.
System age alone is not a diagnosis. Plenty of well-maintained units run past brochure averages.
A company that skips testing on HVAC second opinion 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. Pleasanton, Walnut Creek, and Dublin 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 Pleasanton is not automatically right for a fog-belt house. We treat them that way.

Frequently asked questions
What do you test on a HVAC second opinion visit?
We document findings. If a capacitor, contactor, or flame sensor is the issue, that is what we quote. The visit is a flat $69. Repair work starts only after you approve the written findings.
Will you quote HVAC second opinion from a photo?
No. We do not price HVAC second opinion 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 Pleasanton and Walnut Creek?
Yes. We run Pleasanton, Walnut Creek, 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.
