Furnace not working or no heat? Check these first
A few checks take about a minute and either fix the problem or tell you it's time to call:
- Power switch and breaker. Most furnaces have their own switch, often mounted near the unit and easy to mistake for a light switch — confirm it's on, then check the breaker panel for anything tripped.
- Thermostat. Confirm it's set to "Heat," not "Cool" or "Off," and the target temperature is above room temperature. Dead batteries can leave a display lit while the thermostat isn't actually calling for heat.
- Filter. A badly clogged filter can trigger a safety shutoff that stops the furnace from running at all — check it and swap it if it's visibly dirty.
- Pilot light or ignition. If your furnace has a visible pilot light and it's out, or you smell gas anywhere near the unit, don't try to relight it yourself — turn the system off and call. That's a safety issue, not a troubleshooting step.
If the power, thermostat, and filter all check out and there's still no heat, stop testing and call. One call connects you with one local HVAC professional in our network — no list of companies to compare.
Emergency heating repair near me in Napa County — common problems
If you're searching for emergency heating repair near me because the furnace just quit, you're not alone — here are the most common furnace and heater problems Napa homeowners run into:
No heat or won't ignite
Your furnace runs but produces little or no heat, or won't start at all. A licensed contractor can diagnose whether it's a pilot light, ignition issue, or something else entirely.
Uneven or weak heating
Some rooms stay warm while others feel cold, or the whole house heats slowly. This often points to ductwork issues, thermostat problems, or a blower that needs attention.
Short cycling
Your furnace turns on and off more often than usual. Short cycling wears out equipment and wastes energy, so it's worth having a pro take a look.
Strange noises
Banging, rattling, or squealing sounds from your furnace often signal a loose part, airflow issue, or component that's starting to wear out.
Thermostat not responding
Your thermostat won't turn the heat on, won't hold a set temperature, or reads incorrectly. Could be the thermostat itself or a wiring issue behind the wall.
Rising gas or energy bills
Heating costs climbing even though usage hasn't changed? An aging or inefficient furnace might be running harder to do the job and costing you more each month.
No heat vs. weak heat vs. short-cycling — what each usually points to
These three complaints sound similar but usually trace back to different causes. A closer look:
No heat at all
Often a dead pilot light or ignition failure, a tripped circuit breaker, a blown fuse on the control board, or a thermostat that's lost power or settings. Gas furnaces can also shut down entirely on a safety switch if they detect a problem — that's the system protecting itself, not a random glitch.
Weak or uneven heat
Usually a ductwork issue — leaks, blockages, or a duct system that was never balanced correctly for the home's layout. A clogged filter restricting airflow, or a blower motor losing strength, can also cause heat to trail off before it reaches the far rooms.
Short cycling
A furnace that starts and stops repeatedly is often overheating internally due to a dirty filter or blocked vent, oversized for the home, or dealing with a failing flame sensor or thermostat. Left alone, it accelerates wear on the heat exchanger.
A licensed contractor confirms the actual cause with proper diagnostic tools rather than guesswork — worth knowing before you decide whether it's a quick fix or something bigger.
Should I repair or replace my furnace?
When your furnace breaks, the first question is always: should I fix it or buy a new one? The answer depends on the furnace's age, the cost of the repair, and how often repairs happen.
Repair often makes sense if:
Your furnace is under 15 years old, the repair cost is significantly less than a replacement, and it's a single component failure—not multiple problems piling up.
Consider replacement if:
Your furnace is 15+ years old, repairs keep happening year after year, or energy bills have climbed significantly. A local contractor gives a free, honest assessment to help you decide.
What to expect on a heating service visit
A licensed technician diagnosing a heating problem will typically:
- Ask about the symptoms, when they started, and whether anything changed recently (a new thermostat, recent maintenance, etc.)
- Check the thermostat settings and wiring before assuming the furnace itself is at fault
- Inspect the pilot light, ignition system, or heating element depending on your furnace type
- Test airflow and inspect the filter, ductwork, and blower
- Check the heat exchanger for cracks — a genuine safety issue, not just a comfort one, since a cracked exchanger can leak carbon monoxide
- Walk you through the findings and provide a written estimate before starting repairs
If a contractor mentions the heat exchanger, that's worth taking seriously — it's the one component where "wait and see" isn't a safe option.
What drives heating repair cost up or down
We're not going to hand you an invented price range — furnace type, the specific part involved, and your system's age all change the number, and only a licensed contractor who's looked at your unit can quote it accurately. What tends to move the estimate:
Furnace type and age
Gas, electric, and heat pump systems each have different components and repair costs. Older furnaces can also mean harder-to-source parts, which adds to labor time.
Safety-related repairs
Issues involving the heat exchanger, gas lines, or ignition system are typically more involved — and non-negotiable to address properly — than a simple thermostat or blower fix.
Ductwork condition
If uneven heating traces back to leaky or damaged ducts, sealing or repairing them adds to the job but usually pays off in comfort and lower bills.
How many issues at once
One worn igniter is a quick fix. A furnace failing in multiple ways at once often signals it's nearing the end of its service life, and a contractor should say so plainly.
Furnace tune-ups & maintenance
A seasonal furnace tune-up before winter can catch small issues early—a dirty filter, loose connections, worn parts—before they become costly repairs or leave you without heat. Regular maintenance also keeps your furnace running efficiently and can extend its life. Napa Valley winters are mild but damp, and the first cold snap usually arrives by November — a fall maintenance visit from a local contractor means your furnace is ready before you need it. Homes near the valley floor and along the Napa River corridor tend to deal with more overnight humidity, which can be harder on older heating equipment and ductwork than the drier hillside neighborhoods. Yountville sits away from the river but still gets regular overnight valley fog, so the same pre-winter check applies there too. Calistoga, at the north end of the valley, sits at higher elevation and gets clearer, colder nights than the valley floor, so its furnaces work through a wider temperature swing over the year — worth a check before the season's first frost. St. Helena, further up-valley, shares that older-ductwork pattern in many of its homes built before central heat was standard, which makes the same pre-winter check worth the extra few minutes.

Frequently asked questions
How much does furnace repair cost?
It depends on the furnace type, the specific part involved, and your system's age — there's no honest flat number to give without an inspection. A licensed contractor provides a written estimate before starting any repair.
Why does my furnace smell strange when it first turns on?
A faint dusty smell when a furnace first runs after months of disuse is common and usually harmless. A persistent burning smell, or anything resembling rotten eggs (a natural gas additive), warrants turning off the system and calling a contractor promptly.
How often should a furnace be serviced?
Most contractors recommend an annual tune-up, ideally in the fall before Napa's first cold snap, to catch small issues before they become no-heat emergencies.
Is it safe to run my furnace with a cracked heat exchanger?
No. A cracked heat exchanger can allow carbon monoxide into your home's air supply. If a contractor identifies this, it should be addressed before the furnace runs again, and it's usually a driver toward replacement rather than repair.
Should I replace my furnace and AC at the same time?
If both systems are similar in age, replacing them together can simplify scheduling and sometimes reduces overall labor cost — but it's not required. A contractor can assess each system separately and tell you honestly whether pairing them makes sense for your home.
