When the heat goes out on a cold Seattle night, you need it back fast. Greenwood Heating and Home Services repairs furnaces, heat pumps, ductless systems, and boilers for homeowners across Seattle and King and Snohomish counties. Our technicians find the real cause of the problem, explain your options with upfront pricing, and get your home warm again, day or night.
Heating Systems We Repair
Furnace Repair
Gas and electric furnaces are the most common heating systems in the Seattle area. We repair igniters, flame sensors, blower and inducer motors, control boards, limit switches, gas valves, and thermostats, on all major brands. If your furnace is blowing cold air, won't turn on, or keeps shutting off, we can diagnose it in a single visit in most cases.
Heat Pump Repair
A heat pump that runs constantly, ices over, or blows lukewarm air needs a technician who knows both its heating and cooling sides. We repair compressors, reversing valves, defrost controls, fans, and refrigerant leaks, along with the backup heat that keeps your home warm on the coldest days.
Ductless Mini Split Repair
If one zone stops heating, leaks water, or shows an error code, we troubleshoot the indoor head, the outdoor unit, and the line set between them so every room is comfortable again.
Boiler Repair
Cold radiators, pressure problems, or a boiler that won't stay lit? Our technicians repair hot water boilers and radiator systems. See our boiler services for more.
Signs You Need Heating Repair
- No heat or not enough heat: The system runs, but some rooms never warm up, or it blows cold air.
- Short cycling: Your furnace turns on and off every few minutes instead of running full cycles. This wears out parts and wastes energy. Learn why it happens.
- Strange noises: Banging, squealing, rattling, or scraping usually points to a loose or failing part. What different furnace noises mean.
- Rising heating bills: A system that has to work harder to deliver the same comfort is often due for repair.
- Frequent resets or tripped breakers: A system that keeps shutting down has an underlying problem that won't fix itself.
- A yellow or flickering burner flame: A healthy gas flame burns steady and blue. A yellow flame can mean incomplete combustion and should be checked right away.
If you ever smell gas or your carbon monoxide alarm goes off, leave your home and call your gas utility or 911 first, then call us.
Before You Call: Quick Checks
Some no-heat calls have a simple fix. Before you schedule service, check that:
- Your thermostat is set to Heat, set above room temperature, and has fresh batteries
- Your air filter is not clogged (a dirty filter can cause overheating and shutoffs)
- The breaker for your furnace or heat pump has not tripped
- The furnace access panel is closed securely, since many furnaces will not run with it open
- Supply vents and return grilles are open and not blocked by furniture or rugs
If none of these solve the problem, don't keep resetting the system. Call us, and a technician will take it from there.
24/7 Emergency Heating Repair
Heating systems tend to fail on the coldest nights of the year. Our team offers 24/7 emergency service throughout the Seattle area for every system we repair: furnaces, heat pumps, ductless systems, and boilers. Depending on their tier, Club Members also get priority service during extreme weather and emergencies.
Should You Repair or Replace Your Heating System?
A repair usually makes sense when your system is in good shape and a single part has failed. Replacement is often the smarter investment when:
- Your furnace or heat pump is getting older and needs repairs more than once a season
- A major component, such as the heat exchanger or compressor, has failed
- Your heating bills keep climbing even after repairs
- Some rooms are always too hot or too cold
Our technicians will give you an honest assessment of both paths. If replacement makes more sense, see our furnace installation and replacement options.
Frequently Asked Questions About Heating Repair in Seattle
How much does heating repair cost in Seattle?
It depends on the type of system, the part that failed, and how easy it is to reach. Replacing a flame sensor or igniter costs far less than replacing a blower motor or control board. We'll diagnose the problem and give you an upfront price before any work begins. A diagnostic or trip fee may apply, depending on your Club Membership level.
Can you repair my furnace the same day?
Many common repairs, such as replacing an igniter, flame sensor, or capacitor, can be completed in a single visit. Our trucks carry common parts, and depending on their tier, Club Members get priority service during extreme weather and emergencies.
Why is my furnace running but blowing cold air?
Common causes include a thermostat set to "Fan On," a dirty air filter that triggered a safety shutoff, a failed igniter or flame sensor, or a problem with the gas supply. Here's a closer look at what can cause it.
Why does my furnace keep turning on and off?
This is called short cycling. It is often caused by a clogged filter, a dirty flame sensor, a poorly placed thermostat, or a system that is too large for the home. It puts extra wear on your furnace, so it is worth having it checked.
Do you repair all brands of furnaces and heat pumps?
Yes. Our technicians service all major brands of furnaces, heat pumps, ductless systems, and boilers.
Do you repair oil furnaces?
No, we don't repair oil furnaces. If your oil furnace is failing, we can convert your home to a high-efficiency gas or electric furnace. See our furnace installation and replacement options.
Is it safe to keep using my furnace if it is making noise?
Some noises are harmless, but banging, grinding, or screeching often means a part is failing. If you hear a new noise, turn the system off and call us. Running a damaged furnace can turn a small repair into a big one.
Prevent Breakdowns With Annual Maintenance
Most heating emergencies start as small problems that a yearly tune-up would have caught. Our heating maintenance visits include cleaning and inspecting key components, testing safety controls, and checking for carbon monoxide. Our Club Membership makes it simple. Membership comes in four tiers, and benefits depend on the tier you choose:
- Priority Service: Depending on your tier, members get priority, same-day, or 24-hour service during extreme weather and emergencies.
- Extended Repair Warranties: Repairs we complete while you are a member are covered by a parts warranty, with the length set by your tier.
- Member Savings: Save on repairs and diagnostic fees, with discounts that vary by tier.
- Never Miss a Tune-Up: We'll send a yearly reminder by text, email or phone, whichever you prefer.
