Why Dalton Heating & Air Is Bothell’s Preferred Furnace Repair Company
We are a Garrison Partners company, in operation since 2003 and held to The Garrison Standard on every single job. That standard is not a slogan. It means the price is in writing before any work starts, the repair is guaranteed in writing for a full year, and if the repair fails inside that window, we return at no charge. Bothell homeowners don’t get a different version of that promise than anyone else. They get the same written guarantee, the same background-checked and uniformed technicians, and the same live-answer phone line at 2 a.m.
Marco Benitez oversees our Bothell-area dispatch and scheduling, and he holds every tech to The Garrison Code: arrive inside the stated window, price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year. That discipline matters in a market where a lot of HVAC companies overbook and then no-show. Dispatch for Bothell is coordinated from the brand’s Seattle office, but the crews who knock on your door are local, and they know the housing stock here.
Boiler Repair in Bothell
Boiler Repair in Bothell is a different trade than forced-air furnace work, and the two require different training. We see boilers in older Bothell homes, especially 1960s and 1970s builds around Westhill and the neighborhoods south of downtown along Bothell Way. A boiler that loses pressure, makes knocking sounds, or fails to heat all zones usually needs a circulator pump, an expansion tank, a zone valve, or a pressure-reducing valve. Most boiler repairs in Bothell run $150 to $700, with the higher end involving pump or valve replacement rather than a simple wiring or thermocouple fix.
Circulator Pumps and Zone Valves
A boiler that heats one room but not another is not a mystery. It is almost always a failed zone valve or a circulator pump that has seized. In Bothell, where many older homes run baseboard heat on multiple zones, this is one of the most common boiler failures we see. The repair is usually straightforward: replace the valve or pump, purge the air, and verify flow to every loop.
Pressure and Expansion Tank Problems
Boiler systems run on a specific pressure range, typically 12 to 15 PSI cold. A full expansion tank causes pressure to climb and spill from the relief valve. We see that a lot in Bothell homes with original bladder tanks. Replacing an expansion tank is a quicker fix than most homeowners expect, and it prevents bigger problems down the line.
Gas Furnace Repair in Bothell
Gas Furnace Repair in Bothell is the bulk of what we do between October and March. The climate here is mild but damp, and furnaces run long, low-stage cycles for months. That steady runtime exposes failed ignitors, dirty flame sensors, and worn blower motors faster than a harsher cold climate would. Most gas furnace repairs in Bothell run $150 to $700. A flame sensor cleaning or ignitor replacement lands on the low end. A blower motor or control board replacement lands higher.
Ignitors and Flame Sensors
The ignitor is the part that glows hot to light the gas. When it cracks or burns out, the furnace tries to start and quits. The flame sensor is a thin rod that confirms the flame is actually lit. When it gets coated with carbon, the furnace shuts down seconds after starting. Both are common in Bothell because furnaces cycle on and off constantly through the shoulder seasons, and the sensor gets filthy faster than it would in a single-digit climate.
Gas Valves and High-Limit Switches
A gas valve that will not open means no heat, period. A high-limit switch that keeps tripping usually means the furnace is overheating, which points to a bigger problem: restricted airflow, an oversized blower, or a heat exchanger that is beginning to fail. When we see a high-limit trip on a furnace in Bothell, we do not just reset it and leave. We find out why it tripped, because a tripping limit switch on a gas furnace is a real CO safety concern.
Trusted Brands We Service in Bothell
Our technicians are factory-trained to service nine major residential HVAC brands, and on Bothell service calls we routinely work on Goodman, Rheem, and Carrier equipment. The Bothell housing stock spans decades, so one day we are opening a 1990s Rheem in Canyon Park and the next we are troubleshooting a newer Goodman in a North Creek townhouse. We stock common replacement parts for the brands we service most, which means less waiting on a distributor and faster turnaround when the weather turns cold. If your furnace is a York or a Daikin, you are covered too. The training applies across all nine brands; the parts run is just a little longer.
Common Furnace Repair Problems We See in Bothell Homes
- Oversized furnaces short-cycling. Bothell has a lot of 1980s and 1990s builds that were sized against a generic design temperature, not a real Manual J load calculation. The result is a furnace that fires, slams off, and fires again, never running a full cycle and never heating the house evenly.
- Failed capacitors and blower motors on long low-stage runtime. Bothell’s mild, damp winters mean furnaces run a lot of hours at low stage. That steady runtime wears out capacitors and blower motors faster than in places where furnaces only fire in hard bursts during deep cold.
- Heat exchanger cracks on 20-plus-year-old units. A furnace that was never tuned up may look fine from the outside. Inside, the heat exchanger has been expanding and contracting for two decades, and hairline cracks form. Those cracks are a carbon monoxide risk, not just a repair bill.
- Condensate drain clogs on high-efficiency furnaces. The 90 percent-plus furnaces common in newer Bothell subdivisions produce acidic condensate. When the drain line clogs with sludge, the furnace shuts down on a pressure switch. It is a simple fix when caught early and a bigger one when ignored.
Pricing for Furnace Repair in Bothell, WA
Here is what furnace repair actually costs in Bothell, in writing. A diagnostic call plus a common part replacement, like an ignitor, flame sensor, or capacitor, runs $150 to $700. The range is wide because a bad capacitor is a fifteen-minute job and a blower motor is not. Below is the breakdown we quote from, and these are the same numbers we give on the phone before we arrive.
| Service | Typical Bothell Price |
|---|---|
| Furnace repair (diagnostic + common part) | $150 – $700 |
| Boiler repair | $150 – $700 |
| Seasonal tune-up / thermostat calibration | $80 – $200 |
What moves the number is the part, not the neighborhood. A flame sensor costs less than a control board. We do not charge extra to come to Bothell, and we do not charge more because it is 2 a.m. on a January morning. Call (361) 306-9515 for a free estimate, and the price we give you before any work starts is the price you pay.

FAQs About Furnace Repair in Bothell
Replace it if the heat exchanger is cracked, the furnace is over 20 years old, or the repair bill is more than a third of what a new system costs. In Bothell specifically, we also replace a lot of furnaces that are simply oversized for the house. If your furnace short-cycles, never reaches setpoint upstairs, and your January gas bill is higher than your neighbors’, a load calculation will usually show the unit is 20 to 40 percent bigger than the house needs. Fixing that problem with another repair will not help. Call (361) 306-9515 and we will run the numbers before recommending anything.
Your furnace turns on and off every few minutes because it is overheating or oversized, and the high-limit switch is doing its job by killing the flame. In Bothell, the oversized case is extremely common in 1980s through early 2000s builds. Our tech was called to a 1994 two-story in Canyon Park where a Carrier gas furnace was short-cycling every few minutes and the house never felt warm upstairs. A static pressure reading showed the oversized blower was tripping the high-limit switch, and the heat exchanger had hairline cracks from years of thermal stress. We ran a proper load calculation, confirmed the correct tonnage, and replaced the unit, and the homeowner’s January gas bill dropped noticeably the next month. That is the difference between resetting a switch and fixing the actual problem.
SEER2 is the new federal efficiency rating for cooling equipment, and it matters here because most Bothell homeowners asking about a furnace are really deciding between a gas furnace, an electric heat pump, or a dual-fuel setup. The new standard took effect in 2023, and it means a heat pump rated 15.2 SEER2 under the new test is roughly equivalent to a 16 SEER unit under the old rating. For a Bothell home, a heat pump sized correctly with a real Manual J load calculation will handle our mild winters efficiently. The decision is not just about equipment cost. It is about your actual gas rate, your insulation, and whether the house has ductwork or baseboard heat. We will show you the math in writing before you decide.
Most furnace repairs in Bothell run $150 to $700. The low end covers a diagnostic call plus a simple part like a flame sensor or capacitor. The high end covers a blower motor, control board, or gas valve. We price in writing before any work starts, every time, with no exceptions. That is the Garrison Standard, and it is not a negotiating tactic. Call (361) 306-9515 for an exact quote, free.

If your boiler is knocking, losing pressure, or heating unevenly between zones, call (361) 306-9515 and we will diagnose it the same day.
