AfterFast, Reliable Furnace Repair Across Inverness
Furnace repair in Inverness, CA typically costs $150-$700 and is usually completed in a single visit, with most calls dispatched same-day during heating season. Our technicians are trained specifically on propane-fired heating systems, which is what every home in Inverness runs on.
We answer calls live 24 hours a day, 7 days a week at (817) 402-2972. When your furnace won’t light on a foggy January morning off Sir Francis Drake Boulevard, or you’re driving up from the city to find your Point Reyes cabin ice-cold inside, we’ll get a technician out fast. Our Furnace Repair in Inverness crews understand the local housing stock, the coastal corrosion issues, and the propane-specific problems that dominate service calls here.
Coldharbour Heating & Air has served the Point Reyes area since 2003 as an independently owned and operated member of the Kingswell network. We dispatch and schedule from our Los Angeles office, but our technicians live and work in West Marin. They know the difference between a weekend cabin on Tomales Bay and a year-round home near the Inverness post office, and they treat both with the same written guarantee.
Why Coldharbour Heating & Air Is Inverness’s Preferred Furnace Repair Company
Homeowners in Inverness choose us because we show up in the window we promise, hand you a written price before touching a tool, and back every repair with a 365-Day Done Right Promise on paper. No verbal assurances. No changing the price at the door.
Our technicians are background-checked, uniformed, and trained to service nine major residential HVAC brands including Rheem, York, and Daikin. When you call (817) 402-2972, a live person answers, day or night. We don’t do voicemail trees, and we don’t make Inverness homeowners wait until morning when the temperature inside their cabin is dropping through the fifties.
The Kingswell Way governs how we operate: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, and come back if it fails. Victor Mancini built Coldharbour on these standards, and they apply to every job from a pilot-assembly cleaning to a full heat-exchanger inspection.
Boiler Repair in Inverness
Boiler Repair in Inverness means working on propane-fired hydronic systems, not natural-gas boilers, because there are no gas mains serving this part of West Marin. Most calls involve standing-pilot or electronic-ignition boilers in mid-century cabins that were never designed for year-round occupancy. When a boiler quits here, the technician starts with LP regulator pressure, not a standard gas-line test.
Our boiler repair range runs $150-$700, same as furnace repair. Most jobs fall in the $250-$450 band for igniter replacement, aquastat troubleshooting, or circulator-pump work.
Propane Regulator and Combustion Issues
Boilers in Inverness depend on two-stage propane regulators that degrade in the constant marine humidity. A regulator delivering inconsistent pressure causes erratic firing, sooted burners, and eventual safety lockouts. We test high-side and low-side pressure, rebuild or replace the regulator, and verify combustion with a digital analyzer before we leave.
Corroded Ignition Components in Seasonal Cabins
Many Inverness boilers sit idle through the foggy summer while owners are away. Standing moisture attacks pilot assemblies, flame sensors, and burner orifices. We see this constantly in the vacation-rental stock near Tomales Bay. The fix is usually straightforward: clean or replace the affected parts, check the heat exchanger for flue corrosion, and document the condition for the owner.
Gas Furnace Repair in Inverness
Gas Furnace Repair in Inverness is always propane furnace repair. Every system we touch runs on LP from an on-site tank, which changes the diagnostic sequence entirely. Our technicians check tank level, regulator output pressure, and LP orifice condition before they ever open the furnace cabinet. The salt-laden, near-100% humidity air off Tomales Bay corrodes outdoor regulators, flex connectors, and flue terminations years faster than in inland Marin.
Typical gas furnace repair in Inverness runs $150-$700. A failed igniter or dirty flame sensor usually lands around $180-$320. Heat-exchanger inspection adds time but catches the corrosion that coastal exposure drives into flue components.
Ignition Failures After Idle Periods
This is the call we get every October. Owners return to their Inverness cabin after six foggy weeks away, turn the thermostat up, and nothing happens. The pilot assembly or hot-surface igniter has corroded to the point it won’t hold flame. We replace the assembly, check the flex connector for cracks, verify regulator function, and test-fire the system. Most of these repairs stay well under $400.
Heat Exchanger and Flue Corrosion
Marine air doesn’t stop at the furnace cabinet. It works into flue pipes, draft hoods, and heat-exchanger seams. We inspect visually and with a borescope when indicated. A compromised heat exchanger is a safety issue: combustion gases can enter the living space. We document our findings in writing and explain exactly what we’re seeing before recommending any next step.
Trusted Brands We Service in Inverness
Our technicians carry training and common parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Inverness homeowners, that means faster resolution without waiting for a parts run to Santa Rosa or San Rafael. We stock Rheem and York igniters, Bryant flame sensors, and Daikin control boards on our trucks. When a propane furnace fails on a Friday evening near Point Reyes Station, that inventory difference can mean heat by bedtime instead of a weekend of space heaters.
Common Furnace Repair Problems We See in Inverness Homes
- Corroded pilot assemblies on propane furnaces after foggy off-seasons. The standing moisture in an unheated cabin attacks brass and steel components. We replace the pilot assembly and adjacent flex connector, then verify the rebuilt regulator holds steady pressure before lighting the system.
- Degraded LP flex connectors and regulators on on-site tanks. The rubber and braided-steel connectors between tank and house harden and crack in the marine environment. We treat every no-heat call as a potential leak hazard until we’ve inspected the full gas path.
- Flue and heat-exchanger corrosion from salt-laden bay air. This is the hidden damage. The same coastal exposure that rusts out air-conditioner coils in five years instead of fifteen also eats flue fittings and heat-exchanger seams. We inspect these every time we open a furnace.
- Standing moisture in ductwork and cabinets from weeks of vacancy. Inverness’s near-100% humidity mornings mean a shut-down system can accumulate condensation inside. That moisture corrodes blower motors, control boards, and burner assemblies. We check for water staining and mold indicators during every service.
Pricing for Furnace Repair in Inverness, CA
We don’t guess at prices over the phone, and we don’t change them at the door. A written estimate is handed to you before any work begins. That’s The Kingswell Way.
| Service | Typical Range in Inverness |
|---|---|
| Gas Furnace Repair | $150-$700 |
| Boiler Repair | $150-$700 |
| Tune-Up | $80-$200 |
Most Inverness furnace repairs fall between $180 and $450. A simple igniter replacement runs $150-$280, parts and labor included. More involved work, like regulator rebuilding plus multiple corroded components, can push toward the upper end. What drives cost: accessibility of the unit (crawl spaces are common in the cabin stock), age and parts availability for older propane boilers, and whether the heat exchanger needs inspection or repair.
Every repair comes with our written 365-Day Done Right Promise. If the same failure returns within a full year, we come back and correct it at no charge. Call (817) 402-2972 for an exact quote on your system. Estimates are free.

FAQs About Furnace Repair in Inverness
The pilot assembly or hot-surface igniter has corroded from weeks of fog and near-100% humidity. We replace the affected components, inspect the flex connector for cracks, and verify the two-stage regulator is delivering clean LP pressure before relighting. Call (817) 402-2972 for an exact quote - estimates are free.
Inverness has no natural gas mains at all. Every gas appliance runs on propane, so furnace repair starts with tank-level and regulator diagnosis, not a standard gas-line pressure test. Technicians must be fluent in LP-specific orifices, combustion settings, and code provisions that differ from natural gas. This is why a generic furnace tech from inland Marin can miss the root cause.
We recommend an annual tune-up before heating season, and a mid-season check if the property sits vacant more than it is occupied. The $80-$200 tune-up catches corrosion before it causes a no-heat failure. For rental properties near Tomales Bay, we can set up a pre-arrival inspection so guests never walk into a cold cabin.
Yes. The same marine air that rusts outdoor equipment corrodes flue terminations, regulator fittings, and cabinet components. We inspect for this specifically on every Inverness call and can recommend coated or stainless options when replacement makes sense. The damage is often hidden until a technician looks for it.
We service most propane boilers regardless of age, provided parts are available and the heat exchanger is sound. Many Inverness cabins run boilers from the 1970s and 1980s that just need a new aquastat, circulator, or ignition assembly. We give you a written condition assessment and let you decide. If replacement is the better path, we provide a fixed-price quote with no pressure.
