A furnace that won't start on a wet, 38°F Auburn night leaves children, older adults, pets, and tenants without dependable heat. We repair gas, propane, and electric furnaces — and we treat every no-heat call with the urgency and safety it deserves.
Common Furnace Problems We Fix
Auburn's January normals — an average high of 56.3°F and a low of 37.8°F — mean your furnace works hard through wet winters. The failures we see most often include:
- Furnace won't ignite or the burners light then shut off
- Blower runs but the air is cold, or no air moves at all
- Short cycling — heat kicks on and off every few minutes
- A cracked or failing igniter, flame sensor, or gas valve
- Loud bangs, rattles, or a persistent burning smell
- The thermostat calls for heat but nothing responds
- Repeated breaker trips or a furnace that keeps locking out
Gas or burning smell? Act first.
If you smell gas, leave the building and call the gas utility or 911 from a safe location. If you smell burning or see smoke or arcing, shut the furnace off at the switch and breaker. Don't keep resetting a furnace that locks out — see our guide on when to shut your furnace off immediately.
Safe, Thorough Furnace Diagnosis
Heating repair is safety work. We inspect the ignition system, flame sensor, gas or propane controls, blower motor, control board, and safety switches, and we check the heat exchanger for cracks that can leak combustion gases. We test the failed component instead of guessing from the furnace's age, then explain exactly what failed and why before any chargeable repair.
Propane and Rural Foothill Heating
Many homes in Bowman, Applegate, Ophir, and the rural stretches around Auburn run on propane rather than natural gas. Propane furnaces have their own quirks — regulator issues, different orifices, and tank-supply problems that mimic furnace faults. We service them regularly; our propane furnace troubleshooting guide covers the rural-specific issues. If your system is failing repeatedly, ask about furnace replacement or a heat pump.
Repair Cost and Honest Options
We quote the diagnostic fee up front and the repair in writing before proceeding. On an older furnace with a cracked heat exchanger or repeated failures, we'll show you the repair-versus-replace math honestly — a safety-critical crack is one of the few times we recommend replacement without hesitation.
What's Included When We Repair Your Furnace in Auburn
Heating repair is safety work, so our furnace calls go further than getting the burners lit again. Before we call a furnace fixed, we confirm it's safe to breathe around and won't lock out an hour after we leave. On a standard repair visit you get:
- A carbon-monoxide check and combustion inspection, because a heating fault can be a safety problem and not just a comfort one
- The heat exchanger inspected and photographed for the cracks that let combustion gas leak into the air you breathe
- A gas or propane manometer reading to confirm the burner is actually getting the correct fuel pressure
- The hot-surface igniter and flame sensor tested, then cleaned or replaced — the two most common no-heat culprits by a wide margin
- Limit switches, pressure switches, and the control board checked so a safety lockout isn't quietly covering for a deeper fault
- The blower motor, capacitor, and airflow verified, with the temperature rise confirmed inside the furnace's nameplate range
- A written summary of what failed, what we did, and the flat diagnostic fee
What Affects the Cost of Furnace Repair in Auburn
Furnace repair is diagnostic-based — the price follows the specific failure, not a flat menu. A quick flame-sensor cleaning and a failed gas valve are worlds apart in cost, and until we've actually tested the system we can't tell you honestly which one you're dealing with. Here's what drives it:
- The failed part — a flame sensor or igniter is a modest fix, while a gas valve, inducer motor, control board, or blower motor costs more
- Fuel type — propane systems in the rural foothills have regulators, orifices, and tank-supply issues that need their own diagnosis and can mimic a furnace fault
- Whether the heat exchanger is cracked, which turns a repair into a safety-driven replacement decision we won't sugarcoat
- Parts availability for older or discontinued furnaces, which can mean a sourcing delay in the middle of a cold snap
- Access to the furnace — a cramped closet, attic, or crawlspace unit adds labor time
- After-hours or freezing-night emergency timing versus a scheduled daytime call
We quote the flat diagnostic fee before we come out and the repair in writing before proceeding — always get both in writing. On an older furnace with a cracked heat exchanger or a string of piling-up repairs, we'll show you the repair-versus-replace math honestly rather than nursing a system that's ready to be retired.
Don't keep resetting a locked-out furnace
A furnace that ignites and then shuts off, or that trips a lockout, is protecting you from something — a flame, overheating, or venting fault. One reset is fine to rule out a fluke. If it locks out again, leave it off and call us. Repeated resets can override a safety response to a real problem.
Why Auburn Homeowners Choose The HVAC Auburn CA

Furnace Repair Across Auburn & Placer County
Plenty of the homes we heat run on propane rather than natural gas, so we know the rural foothills as well as the city streets. We repair gas, propane, and electric furnaces in North Auburn, Meadow Vista, Bowman, Applegate, and Colfax, and across the rest of Placer County. On a hard-freeze night we treat every no-heat call as urgent, since a cold house quickly turns into a frozen-pipe problem on top of an uncomfortable one. Tell us if there are infants, older adults, or pets in the home when you call so we can prioritize the dispatch.

Frequently Asked Questions
Confirm the thermostat is set to heat and above room temperature, check that the furnace switch and breaker are on, and make sure the filter isn't badly clogged. If it still won't run — or if you smell gas or burning — stop there and call us. Don't repeatedly reset a furnace that keeps locking out; that lockout is a safety feature protecting you.
Yes. We service gas, propane, and electric furnaces throughout Auburn and rural communities like Bowman, Applegate, and Ophir. Propane systems have specific regulator, orifice, and tank-supply issues we diagnose regularly rather than mistaking a supply problem for a furnace fault.
Yes. A cracked heat exchanger can leak carbon monoxide into your home's air. If we find one, we'll show you the evidence and recommend shutting the furnace down until it's replaced or the furnace is replaced. This is one failure where we don't soft-pedal the safety risk.
We prioritize no-heat calls, especially during cold snaps, and offer 24/7 emergency furnace service. Same-day service is typical in Auburn and North Auburn. Call +1 (327) 210-5999 and tell us if vulnerable occupants are in the home so we can dispatch accordingly.
A dusty, faintly burning smell during the first heating cycle of fall is usually normal — it's dust that settled on the heat exchanger over the summer burning off, and it should clear within an hour or two. What isn't normal is a persistent burning-plastic or electrical smell, a hot metallic odor that lingers, or any smell of gas. If the smell doesn't fade, or it comes with smoke, shut the furnace off and call us.
Most common no-heat repairs — a flame sensor, hot-surface igniter, or pressure switch — take about an hour once diagnosed, since we carry those parts on the truck. A gas valve, inducer motor, control board, or blower motor can take longer, especially if the part has to be sourced for an older furnace. We give you a time estimate with the written price before we begin.
