AfterFast, Reliable Furnace Repair Across Kentfield
Most furnace repairs in Kentfield run $150 – $700, and we can typically have a technician at your door the same day you call. That’s the range you should expect for a proper diagnostic and fix on a gas furnace, whether it’s an ignitor on a Rheem or a blower motor on a Carrier. Call (361) 306-9515 and a live person answers, 24 hours a day, no voicemail queue.
We know Kentfield’s heating demands aren’t the same as a mountain town’s. Homes here sit under mature oak and redwood canopy, on slopes and shaded lots off Sir Francis Drake. The marine air keeps winter temperatures moderate, which means your furnace runs long, low-demand cycles instead of hard, deep-freeze blasts. That changes what fails and how it gets fixed.
Why Dalton Heating & Air Is Kentfield’s Preferred Furnace Repair Company
Dalton Heating & Air operates under The Garrison Standard, a set of rules in place since 2003 that most HVAC companies won’t put in writing. Every repair gets a written price before any work starts. Every repair carries a written guarantee for a full year. If the repair fails inside that year, we return at no charge. Those aren’t upgrades or add-ons. They’re the terms of every single call.
Marco Benitez leads our team. He holds every technician to The Garrison Code: arrive inside the stated window, put the price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year. We don’t send subcontractors. You’ll know who’s coming before they arrive because our technicians are background-checked and uniformed.
For Kentfield specifically, response time matters. Whether you’re up in the canyon neighborhoods or down in the flats near College of Marin, a no-heat call shouldn’t mean waiting until tomorrow. We dispatch locally from our San Francisco Bay Area office and prioritize Kentfield calls the same day they come in.
Gas Furnace Repair in Kentfield
Gas Furnace Repair in Kentfield usually means diagnosing a furnace that won’t light, won’t stay lit, or blows cold air. We inspect the ignitor, flame sensor, gas valve, and heat exchanger, then give you a written price for the exact part and labor before we touch anything. A typical gas furnace repair in Kentfield runs $150 – $700, and most jobs are finished in a single visit.
Ignitor and Flame Sensor Work
Older gas furnaces in Kentfield often fail to light because the ignitor has cracked or the flame sensor has built up oxidation from years of on-and-off cycling through mild winters. We carry common ignitors and sensors for Goodman, Rheem, York, and Daikin units on our trucks, so there’s no second trip to a parts house across the county.
Gas Valve and Heat Exchanger Checks
When a furnace fires but won’t produce consistent heat, we test gas pressure at the valve and inspect the heat exchanger for cracks. Here’s the safety truth: a compromised heat exchanger can leak carbon monoxide, so this is not a repair to attempt yourself. Our technicians carry combustion analyzers and carbon monoxide detectors on every call to Kentfield homes.
Furnace Tune Up in Kentfield
Furnace Tune Up in Kentfield is the service we recommend every fall, before temperatures drop into the marine-influenced cool season. A tune-up runs $80 – $200 and takes about an hour. We clean the burners, check the flame sensor, test the capacitor, measure static pressure, and verify the thermostat is reading accurately.
Static Pressure and Airflow Correction
Kentfield homes built with ductwork sized for cooling-only loads often have static pressure problems that show up as uneven heat, cold rooms, and a blower that runs too long. During a tune-up we measure static pressure at the return and supply and adjust blower settings to match what the ductwork can actually handle. That correction alone fixes a surprising number of “furnace isn’t heating evenly” complaints.
Thermostat Calibration Check
A thermostat that’s off by even three or four degrees makes a furnace behave strangely. It short-cycles, overheats the room it’s in, or never satisfies the call for heat. We calibrate or reposition thermostats during every tune-up, which is especially useful in Kentfield homes where the thermostat sits near a shaded wall or a drafty window.
Trusted Brands We Service in Kentfield
Our technicians are factory-trained to service nine major brands, and in Kentfield we see a lot of Carrier, Lennox, Goodman, and Rheem equipment that’s been in service since the early 2000s. We stock common parts for Goodman, Rheem, York, and Daikin furnaces on the truck, which means faster turnaround for Kentfield customers. If your unit is one of those brands and the part is a common failure item, there’s a good chance we fix it the same day without waiting on supply house runs.
Common Furnace Repair Problems We See in Kentfield Homes
- Short-cycling gas furnaces. Kentfield canyon homes and heavily shaded properties often have oversized furnaces that blast heat for a few minutes, shut off, and repeat. That’s usually an airflow or sizing issue, not a cracked heat exchanger. We check static pressure and return-air sizing before recommending any replacement.
- Blower motor and capacitor failures. Mild winters mean Kentfield furnaces run long, low-demand cycles. That wear pattern ages blower motors and capacitors on older Carrier and Lennox units, which fail as a no-heat call even though the burner itself is fine.
- Thermostat calibration drift. Older thermostats in Kentfield homes, especially analog units near shaded exterior walls, can read several degrees off. The furnace responds by running too long or short-cycling, and the fix is often a simple calibration or thermostat replacement.
- Duct static pressure imbalance. Homes on slopes and under heavy tree canopy often have return-air openings that are too small or blocked. The furnace works harder than it should, which shortens component life and makes some rooms consistently colder. This is a tune-up fix, not a replacement.

FAQs About Furnace Repair in Kentfield
Most short-cycling in Kentfield is a repair issue, not a replacement one. We trace it to blocked returns, improper blower settings, or an oversized furnace installed for a house that never needed that much heat. A tune-up and airflow correction fixes many of these for $80 – $200. Replacement only makes sense if the heat exchanger is cracked or the unit is beyond its service life. Call (361) 306-9515 and we’ll tell you straight which one you’re dealing with.
Shade, slope, and ductwork. Homes in Kentfield that sit under mature oak and redwood canopy, or that back up against a shaded hillside, have a higher heating load than a sun-exposed home on the flats. If your ductwork is sized for cooling-only, the furnace also has to push air through undersized returns, which makes it run longer to satisfy the thermostat. We measure both the load and the static pressure before recommending a fix.
A tune-up catches flame sensor oxidation, capacitor wear, thermostat calibration drift, gas valve pressure issues, and static pressure problems. In Kentfield, where furnaces run long mild cycles rather than short hard ones, the most common tune-up findings are blower-related: capacitors that are about to fail and blower settings that don’t match the ductwork. Expect a written report of what we found and what it costs to fix.
An honest quote is written, specific, and doesn’t change at the door. It names the part, the labor, and the total before work starts. That’s exactly what Dalton Heating & Air provides on every call. If a quote shifts after the technician arrives, or if you’re told a part needs replacing without being shown why, get a second opinion. Our price is in writing, every time, without exception.
Fifteen years is the age where repair-versus-replace gets serious, but it’s not automatic. In Kentfield’s mild climate, a well-maintained Carrier or Lennox from the late 2000s often has several good years left. The decision comes down to the heat exchanger and the blower. If the heat exchanger is sound and the blower tests fine, repair usually makes sense. If both are failing, replacement is the better money. We’ll show you the test results and give you both options in writing. Call (361) 306-9515 for an honest assessment.
In the flats off Sir Francis Drake in Kentfield, our tech answered a no-heat call on a 2008 Carrier gas furnace where the blower motor was pulling high amps and the thermostat calibration was reading 4°F off. We tested the capacitor, confirmed the heat exchanger was sound, corrected the blower settings against the home’s static pressure, and had heat restored the same visit. We also advised the homeowner that the unit was still well within its service life and did not need replacement.
Kentfield’s furnace load is driven by cool, marine-influenced nights and heavily shaded lots under mature oak and redwood canopy, not by deep freezes. So most “furnace failures” we see are short-cycling and airflow problems rather than cracked heat exchangers from hard freezing. Because homes here sit on slopes and in shade, duct static pressure and return-air sizing matter more to heating performance than the outdoor design temperature does.
If your furnace is acting up in Kentfield, call (361) 306-9515. A live person answers, the price is in writing before work starts, and the repair is guaranteed for a full year.
