AfterFast, Reliable Furnace Repair Across Kensington
Furnace repair in Kensington, CA typically runs $150 – $700, and most jobs are diagnosed and fixed in a single visit. We cover every neighborhood in Kensington, from the hills above Arlington Avenue down to the flats near Colusa Avenue, with response times under two hours for no-heat calls during heating season. If your furnace is short-cycling, tripping the high-limit switch, or blowing cold air, call (361) 306-9515 and a live person answers 24/7. We arrive in a marked van, put the price in writing before any work starts, and guarantee the repair in writing for a full year.
Kensington’s housing stock skews older, which means most furnaces we see are well past their tenth birthday. That’s not a bad thing. A decades-old Carrier or Rheem that gets a proper tune-up and an honest diagnosis can run reliably for years. Our job is to tell you when a $200 repair makes sense and when it doesn’t, without pushing a replacement you don’t need.
Why Dalton Heating & Air Is Kensington’s Preferred Furnace Repair Company
Dalton Heating & Air operates under The Garrison Standard, a set of rules that has governed how we work since 2003. Every Kensington call gets the same four commitments: we arrive inside the stated window, the price is in writing before any work begins, the job is done by the book, and the repair is guaranteed for a full year. If it fails in that time, we come back at no charge. That’s the 365-Day Done Right Promise, and it means exactly what it says.
Our Kensington customers know who is coming before we knock. Every technician is background-checked, uniformed, and factory-trained to service nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Marco Benitez leads the team that handles Kensington dispatch and scheduling from our San Francisco Bay Area office, so when you call, you’re talking to someone who knows the area’s homes and heating systems.
We’re not the cheapest crew in Kensington, and we won’t pretend to be. What we offer is a fixed price you approve before we start, a technician who explains the problem in plain English, and a written guarantee that backs the work for 365 days. Homeowners who have been burned by no-shows and door-price changes tend to stick with us.
Gas Furnace Repair in Kensington
Gas Furnace Repair in Kensington usually means one of three things: an ignition failure, a gas valve that won’t stay open, or a safety limit switch that keeps killing the burners. The first sentence of any repair call is diagnosis. We check the heat exchanger for cracks, measure gas pressure at the valve, and test the ignitor and flame sensor before recommending a fix. Most gas furnace repairs in Kensington fall between $150 and $700, depending on the part and the unit’s age.
Ignitor and Flame Sensor Work
An ignitor replacement is one of the most common gas furnace repairs we do in Kensington, especially on older Goodman and York units from the mid-2000s. The ignitor glows hot enough to light the burner, and when it weakens, the furnace either won’t fire or fires inconsistently. A flame sensor that’s coated in carbon can also shut the system down seconds after ignition. Both are quick fixes, usually in the $150 – $400 range.
Gas Valve Diagnosis
A gas valve that’s sticking or failing to hold pressure gets replaced, not band-aided. In Kensington, we see gas valve failures on furnaces that have gone years without a tune-up, especially in homes where dust from older ductwork has worked its way into the valve body. The part itself runs $200 – $500 installed, and we verify the valve is the actual problem before we replace it.
Furnace Tune Up in Kensington
Furnace Tune Up in Kensington runs $80 – $200 and is the single best way to prevent a no-heat night in December. The tune-up includes checking gas pressure and combustion, testing the high-limit and rollout switches, cleaning the flame sensor, inspecting the heat exchanger, and measuring temperature rise across the system. We also check static pressure, which matters a lot in Kensington’s older homes where undersized return ducts are common.
A furnace that hasn’t been tuned in three or four years is running dirtier and hotter than it should. That’s not a guess, it’s a measurement. We read the numbers, show you what we found, and adjust the system so it runs within manufacturer spec. The written report you get after the tune-up is yours to keep, whether you hire us for more work or not.
Static Pressure and Airflow Check
Kensington homes built before 1980 often have return duct systems that were sized for gravity heat, not forced air. When a modern furnace pushes air through those undersized returns, static pressure climbs, the high-limit switch trips, and the furnace shuts down. Our tune-up includes a static pressure reading that catches this problem before it becomes a winter emergency.
Blower Motor and Capacitor Inspection
Failed capacitors and weak blower motors keep showing up as no-heat or intermittent-heat calls in aging Goodman and Rheem units that haven’t had a tune-up. During the tune-up, we test the capacitor under load and inspect the blower motor bearings. Replacing a weak capacitor during a tune-up costs less than a service call at 2 a.m. when the motor finally gives out.
Trusted Brands We Service in Kensington
Dalton Heating & Air services all nine major residential HVAC brands, and in Kensington we see a lot of Rheem, York, Daikin, and Bryant furnaces in the older hillside homes. We keep common components for these brands on our trucks, which means faster turnaround when a Kensington furnace goes down. Whether your system is a 1998 Carrier, a 2007 York, or a newer Daikin, our technicians are factory-trained on the specific ignition systems, control boards, and gas valves those brands use. You won’t find us guessing at a wiring diagram. We know the equipment, and we stock the parts that fail most often.
Common Furnace Repair Problems We See in Kensington Homes
- High-limit switch trips from dirty filters and blocked returns. Kensington’s older homes often have undersized return ducts, and when filters clog or vents get blocked, the furnace overheats and shuts down. A static pressure test catches the airflow problem fast, and the fix is usually a filter replacement or a return duct adjustment, not a new furnace.
- Failed capacitors and blower motors on aging Goodman and York units. We get no-heat calls every winter on furnaces that haven’t had a tune-up in years, and the culprit is often a capacitor that costs under $50 to replace. Testing these components during a tune-up prevents the 2 a.m. failure.
- Thermostat calibration drift causing short cycling. When the thermostat reads wrong, the furnace turns on and off too often, wearing out the ignitor and gas valve. We see this a lot in Kensington homes with older mechanical thermostats, and the fix is usually a calibration or a thermostat replacement in the $100 – $300 range.
- Cracked heat exchangers on furnaces past 15 years old. A cracked heat exchanger is a carbon monoxide risk and means the furnace should be replaced. We inspect the heat exchanger on every repair call, because in Kensington’s older housing stock, the difference between a repairable furnace and a dangerous one comes down to this check.

FAQs About Furnace Repair in Kensington
Short-cycling usually means a thermostat calibration problem, a dirty flame sensor, or a clogged filter, all of which are repairs in the $100 – $400 range, not replacement-level work. We diagnose the cause before recommending anything. If the short-cycling is caused by an oversized furnace or a failing control board, we’ll tell you honestly and run a load calculation so you know what a correctly sized replacement would cost. Call (361) 306-9515 to schedule a diagnosis.
A furnace tune-up in Kensington runs $80 – $200 and includes gas pressure and combustion testing, flame sensor cleaning, high-limit and rollout switch verification, heat exchanger inspection, blower motor and capacitor testing, and a static pressure reading. You get a written report of what we found, with photos and measurements, whether or not you approve additional work.
The high-limit switch trips when the furnace gets too hot, usually because airflow is restricted by a dirty filter, a blocked return duct, or an undersized duct system, which is common in Kensington’s older homes. We run a static pressure test to pinpoint the restriction, and the fix is often a filter change or a duct adjustment rather than a major repair. Call (361) 306-9515 for a diagnosis.
SEER2 is the updated efficiency testing standard that went into effect in 2023, and it reflects more realistic operating conditions than the old SEER rating. For a furnace repair, SEER2 doesn’t change the parts or labor, but it matters if you’re weighing repair versus replacement, because a new high-efficiency furnace will carry a SEER2 rating that directly affects your gas bill. We’ll explain the numbers on the label so you know what you’re paying to run.
Yes. We’re factory-trained on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If your furnace isn’t on that list, we’ll still diagnose it, but we stock parts for the nine brands we know best, which covers the large majority of furnaces in Kensington.
