Burning smell from the furnace
Dust on the heat exchanger vs an electrical smell. Different urgency.
A brief dusty smell on the first heat call of fall is common. A hot electrical smell is not.
No heat is usually an ignitor, flame sensor, pressure switch, or thermostat — not an automatic furnace replacement.
If the search that brought you here was “burning smell furnace,” start with a test, not a replacement pitch.
We test ignition, flame proving, inducer, and safety switches. Age is a data point, not a diagnosis.
On this call we confirm the symptom you described — burning smell from the furnace — before we open a price book.
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.
“It’s 15 years old, you need a new system” without readings is a pitch. We show the failed part first.
A company that skips testing on burning smell furnace 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. Dublin, Clayton, and San Ramon 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 Dublin is not automatically right for a fog-belt house. We treat them that way.
