A heater that stops working on a cold Calaveras County night isn't just uncomfortable — it can be a safety concern. West Coast Air Conditioning diagnoses and repairs all types of heating systems, quickly and honestly.
Our technicians are trained in gas furnace diagnostics, heat exchanger inspection, ignition systems, and heat pump heating repair. We work on all brands and don't recommend unnecessary parts or services. If your furnace can be repaired, we'll repair it. If it can't, we'll tell you honestly.
We service gas furnaces, propane furnaces, electric furnaces, and heat pump heating systems for homes throughout Valley Springs, San Andreas, Stockton, Lodi, and surrounding Calaveras and San Joaquin County communities.
If your furnace is blowing cold air, common causes include a tripped limit switch due to overheating, a dirty filter restricting airflow, an ignition or pilot failure, or a thermostat set incorrectly. A heat pump blowing cold air in temperatures below 35°F may be in defrost mode — that's normal. If it persists, call us at (209) 598-8889.
A well-maintained gas furnace can last 20–30 years. If you're having repeated repairs on a furnace over 20 years old, the money is often better spent on a new, more efficient system. We'll give you an honest side-by-side comparison — no pressure.
Yes. A cracked heat exchanger can allow carbon monoxide to enter your living space, which is a serious safety hazard. If we find a crack during an inspection, we'll show you what we found and explain your options clearly. This is one situation where we may recommend replacement over repair.
Furnace repair costs vary by the part and labor involved. Minor fixes like a thermostat or igniter replacement cost less; heat exchanger or control board work is more involved. We always give you a clear price before starting any work. Call (209) 598-8889 for a diagnosis.
