Heating Repair in Northwest Washington
No Heat · Cold Rooms · Strange Noises · Short Cycling · Leaking. Licensed heating specialists diagnosing and fixing every system type fast across Bellingham, Mount Vernon & Anacortes.
When Your Heating System Stops, Every Room Goes Cold at Once
Whether your furnace won't ignite, your boiler is leaking, your heat pump is blowing cold air, or your radiant floor has gone cold, the result is the same — no heat in your home during a Northwest Washington winter. Pipes start freezing within hours. The problem will get worse and the repair will get more expensive the longer you wait. You need a company that can diagnose and fix any heating system, not just one type.
LaVergne's diagnoses and repairs every type of heating system including furnace ignition failure, boiler circulator and zone valve problems, heat pump compressor and refrigerant issues, gas valve malfunction, control board failure, cracked heat exchangers, blower motor problems, thermostat wiring issues, pressure relief valve failures, and radiant loop problems across Bellingham, Mount Vernon, Anacortes, and all of Whatcom and Skagit Counties.
What to Look for in a Heating Repair Specialist
Heating repair spans gas combustion systems, pressurized hydronic loops, refrigerant circuits, high voltage electrical, digital controls, and mechanical components. A technician who only knows furnaces can't fix a boiler. One who only knows forced air can't diagnose a heat pump. And one who guesses replaces parts that aren't broken, misses the real cause, and leaves you with the same problem. Here's what matters.

Most Common Heating Problems We Repair
Heating systems in Northwest Washington face cold snaps, aging components, deferred maintenance, and normal wear. Each system type has its own predictable failure points, but the result is always the same — no heat when you need it most. Here are the four heating problems we repair most often.
Our trucks carry parts for furnaces, boilers, and heat pumps so the majority of heating repairs are completed in a single visit regardless of system type.
No Heat at All
Furnace ignition failure, boiler pilot out, heat pump compressor down, or thermostat not calling. The most common heating emergency. We diagnose the exact cause on any system and restore heat fast.
Fix It →Uneven Heat / Cold Rooms
Zone valve stuck on a boiler, duct damper closed on a furnace, ductless head not responding, or air in radiant loops. We trace the distribution problem and restore heat to every room and zone.
Balance →Strange Noises
Banging from delayed ignition, kettling from boiler scale, squealing from blower bearings, gurgling from air in hydronic lines, or clicking from a failing relay. We identify the source and fix it.
Quiet →Leaking or Dripping
Boiler pressure relief valve discharging, condensate leak from a high efficiency furnace, refrigerant line sweating on a heat pump, or hydronic pipe joint leak. We find the source and stop it.

Why Professional Heating Repair Matters
Heating systems involve gas combustion, pressurized water, refrigerant circuits, high voltage electrical, and mechanical components depending on type. Improper repair on a furnace creates CO exposure. A bad fix on a boiler creates pressure hazards. Incorrect refrigerant work destroys a heat pump compressor. Misdiagnosis replaces parts that aren't broken while missing the real cause.
Licensed heating specialists diagnose systematically using combustion analysis, pressure testing, refrigerant gauges, electrical testing, and experience across every system type. They test before and after every repair, verify safety devices, and ensure your heating system operates safely and correctly before leaving.

Heating Repair FAQs
Common heating repair questions answered by our licensed specialists serving Whatcom and Skagit Counties.
How much does heating repair cost?
Most heating repairs run $150 to $800 depending on system type and component. Simple fixes like igniters and flame sensors are lower. Compressor, circulator pump, or control board work runs higher. We always quote upfront.
What heating systems do you repair?
Gas furnaces, boilers, heat pumps, ductless mini splits, radiant floor systems, electric baseboard, wall heaters, dual fuel hybrids, and commercial heating equipment. Every type, every brand, every component.
Why is my heating system not working?
Most common causes depend on type. Furnaces: igniter or flame sensor. Boilers: circulator pump or zone valve. Heat pumps: refrigerant or defrost board. We diagnose the exact cause on any system and restore heat fast.
Why are some rooms cold?
Uneven heat comes from stuck zone valves on boilers, closed dampers on furnaces, air in radiant loops, failed ductless heads, or restricted ductwork. We trace the distribution problem and restore heat to every room.
Should I repair or replace?
Under 15 years and repair is less than half replacement cost, repair makes sense. Over 15 to 20, frequent repairs, cracked heat exchanger, or failed pressure vessel means replacement is safer and more cost effective.
Do you carry parts on your trucks?
Yes. Our trucks stock common parts for furnaces, boilers, and heat pumps including igniters, flame sensors, capacitors, circulators, zone valves, gas valves, control boards, thermostats, and filters for same day repair.
Why is my boiler making noise?
Kettling from scale buildup, banging from air in lines, gurgling from low water level, clicking from a failing relay, or humming from a failing circulator pump. We identify the exact source and eliminate it.
Do you offer 24/7 emergency repair?
Yes. When your heating system fails in freezing weather, we respond 24/7 regardless of system type. A heating failure in winter risks frozen pipes and serious discomfort. Call anytime and we will get there fast.
What areas do you serve?
We repair all heating systems across Whatcom and Skagit Counties including Bellingham, Mount Vernon, Anacortes, Burlington, Sedro Woolley, Ferndale, Lynden, and surrounding areas.
