Fast, Reliable Furnace Repair Across Kent
A furnace that quits on a January night in Kent isn’t something to wait out. We know, because our techs take those calls from the valley floor, the East Hill, and the West Hill every winter. Most furnace repairs in Kent run between $150 and $700, and we can usually have a background-checked, uniformed technician at your door the same day you call. You’ll get a written price before any work starts, and a live person answers our phone 24/7. Call (747) 966-3037 and tell us what your furnace is doing, or not doing.
Why Meadowsweet Heating & Air Is Kent’s Preferred Furnace Repair Company
We’re part of the Cedarwell family of HVAC companies, founded in 2004, and we built our reputation in Kent by actually understanding how homes here behave in winter. That means we don’t guess. A furnace that short-cycles on the valley floor near downtown usually has a different root cause than one doing the same thing on East Hill, and we’ve seen enough of both to know the difference before we open the access panel. Our techs work on nine major brands, including Trane, Lennox, Goodman, and Rheem, so we’re not learning your equipment for the first time when we arrive.
Every visit follows the Cedarwell Care Promise. That’s a written price before any work begins, shoe covers and drop cloths on your floors, and a photo of the clean-up before the crew walks out. The C.A.R.E. values code is how our techs actually behave: Clean up like it’s their own home, Ask before moving anything, Respect your family’s time and quiet hours, and Explain the price before the work. If something isn’t done right, our 365-Day Done Right Promise means we make it right. No runarounds.
For furnace repair in Kent, our team coordinates dispatch from the Seattle office and keeps crews close to the Green River Valley so response times stay short. Luis Serrano, who leads our crew, has made the call that we’d rather send one tech who knows Kent’s housing stock than two who don’t.
Boiler Repair in Kent
Boiler repair in Kent is its own skill, and older valley-floor homes with original hydronic systems account for a steady share of our winter calls. Many of the 1950s and 1960s ranches between downtown and the Green River levee still heat with boilers, and when one stops firing, the whole house goes cold in a few hours. A typical boiler repair in Kent runs $150 to $700 depending on what failed. We work on gas valves, circulator pumps, expansion tanks, and aquastats, and we’ll give you a written price before we touch anything. If the boiler is older but the loop is sound, a repair usually makes sense. If the heat exchanger is compromised, we’ll tell you that plainly and walk you through the replacement math.
Gas Valve and Circulator Work
On older Kent boilers, the gas valve and the circulator pump are the two most common failure points. A stuck gas valve means no ignition or a weak flame, and a failing circulator usually shows up as heat in one room and cold radiators in others. Both are repairable same-day if we have the part on the truck, and we stock common valves for older hydronic boilers still common in Kent.
Expansion Tank and Pressure Issues
Hard water in the Green River aquifer makes sediment a real variable in Kent hydronic systems. A waterlogged expansion tank or a pressure-reducing valve that’s drifted out of spec will cause the relief valve to drip and pressure to swing. We’ll test the tank, check the fill valve, and show you the gauge readings before we leave.
Gas Furnace Repair in Kent
Gas furnace repair in Kent covers everything from failed ignitors to cracked heat exchangers, and the bulk of our work is on forced-air units in the 1980s and 1990s tract homes on the East and West Hills. Most gas furnace repairs here fall between $150 and $700. Ignitor replacement is the most common fix, often under $300. A blower motor runs higher. A gas valve usually lands mid-range. Before any repair, our tech explains what failed, what it costs to fix, and what the furnace will do afterward. No pressure, just the numbers.
Ignitor and Flame Sensor Issues
When a gas furnace clicks but won’t light, the ignitor is often the culprit. In Kent, we see a concentration of these failures in valley-floor homes where cold-air pooling makes furnaces cycle more often during inversions. More cycles per winter means more wear on hot-surface ignitors. The part itself is modest; the repair usually sits at the lower end of our $150 to $700 range.
Heat Exchanger and Safety Findings
A cracked heat exchanger is the one furnace finding we never patch. It’s a carbon monoxide risk, and we’ll show you the crack with a camera before recommending anything. If the furnace is under warranty or young enough to justify a heat exchanger replacement, we’ll quote it. If not, we’ll give you a fixed price for a proper replacement sized for your Kent home’s actual heat loss.
Blower Motor and Airflow Repairs
A furnace that heats but won’t move air usually points to the blower motor or a failing run capacitor. In Kent homes with under-floor ductwork, we also check for collapsed or waterlogged returns before assuming the motor is bad. Saturated valley soils near the river keep crawl spaces damp year-round, and a rotted duct liner can strangle airflow enough to make a healthy blower look faulty.
Trusted Brands We Service in Kent
Our techs service nine leading equipment brands, and in Kent we stock common replacement parts locally so a furnace repair can happen in one visit instead of two. That matters in February. If your furnace is a Trane, Lennox, Goodman, or Rheem, we know the failure patterns for each model line and we carry the ignitors, flame sensors, gas valves, and blower motors those units need most often. For less common parts, our supplier network gets them to Kent fast, usually within one business day. You’ll know the timeline before we order anything.
Common Furnace Repair Problems We See in Kent Homes
- Oil-era ductwork choking a heat pump. Valley-floor homes converted from oil in the 1990s often have ducts sized for slow oil-furnace airflow. A modern heat pump pushing through those ducts builds high static pressure and short-cycles, which shows up as cold rooms and an electric bill that doesn’t match the thermostat setting.
- Inversion nights driving auxiliary heat for hours. During winter inversions, the Green River Valley floor runs 5 to 8 degrees colder than East Hill minutes away. Heat pumps drop into auxiliary resistance heat to keep up, and a failing capacitor or low refrigerant charge hides behind the strips until the house goes cold in the middle of the night.
- Damp crawl spaces rotting duct liner. The high water table near the river keeps valley crawl spaces humid. Over time that moisture degrades the liner on under-floor ductwork, and the leaks steal conditioned air before it reaches the far bedrooms. Cold spots are the tell.
- Tight closet installs on the hills. On East and West Hill, 1980s and 1990s tract homes pack furnaces into narrow closets with tight clearances. A blower motor or control board replacement there takes longer simply because access is restricted, and noise ordinance limits on outdoor units shape how a repair gets planned. We factor that in before we quote.
Pricing for Furnace Repair in Kent, WA
In Kent, a furnace repair lands between $150 and $700, and the spread comes down to what failed and how hard it is to reach. A diagnostic visit identifies the problem, and you’ll get a written quote with the exact repair cost before we begin. Pricing is honest and line-itemed.
| Service | Typical Kent Price Range |
|---|---|
| Gas furnace diagnostic and repair | $150-$700 |
| Boiler repair | $150-$700 |
| Furnace tune-up | $80-$200 |
What moves a repair toward the top of the range is part cost plus access time. A gas valve on a furnace in a roomy East Hill basement is different from the same valve on a closet unit in a tight 1980s tract home where the tech has to work around water heaters and shelving.

FAQs About Furnace Repair in Kent
Because the valley floor traps cold air during winter inversions, and your property sits 5 to 8 degrees colder than the plateaus around it. Cold, dense air pools between downtown and the Green River levee on clear winter nights, which forces heat pumps into auxiliary resistance heat far more often than a unit on East Hill would ever experience. If that’s happening regularly, we’ll evaluate whether your thermostat is wired to lock out the strips at realistic temperatures, or whether the heat pump itself needs a service check. Call (747) 966-3037 for a diagnostic visit.
The ductwork was sized for oil-furnace airflow, which moves air slower and at lower static pressure than a modern heat pump. When a heat pump was dropped into those same ducts without a duct audit, the system fights itself. A January call in the valley-floor streets between downtown Kent and the Green River levee made this exact problem clear: a 1990s conversion was short-cycling every few minutes, and its auxiliary heat was carrying the house. We ran a load calculation, opened up the return, and rebalanced the branch runs. The heat pump stopped leaning on backup strips even as the inversion layer settled in. On the East Hill the same symptom usually traces to a failing blower motor or a thermostat calibration issue, but in the valley it’s almost always ductwork fighting a heat pump.
Most furnace repairs in Kent do not require a permit. Replacing a furnace or modifying gas piping or venting usually does require a mechanical permit, which the city issues through its building department. We handle permit paperwork for replacements and confirm code compliance on venting and clearances during repairs. If your repair uncovers a venting issue that predates the visit, we’ll document it and tell you what’s needed to bring it up to current Kent code.
Yes. The high water table near the Green River keeps valley crawl spaces humid year-round, and that moisture rots the liner on under-floor ductwork. Deteriorating liner means air leaks, and air leaks mean the furnace works harder to heat the far end of the house. The fix isn’t always a furnace repair; sometimes it’s sealing or replacing duct runs and adding a crawl-space vapor barrier. We’ll inspect the ductwork when we’re out, and we’ll show you photos of what we find before recommending anything.
Most furnace repairs in Kent cost between $150 and $700. A diagnostic visit pinpoints the failed component, and you’ll receive a written quote with the exact cost before work begins. Ignitor replacements sit at the low end. Gas valves and blower motors run higher. Boiler repairs span the same range. A tune-up is $80 to $200. For an exact quote on your specific furnace, call (747) 966-3037. Estimates are free, and a live person answers 24/7.
