AfterFast, Reliable Furnace Repair Across Hillsborough
Furnace repair in Hillsborough typically costs $150 – $700 depending on the failed part, and most calls we take in this town are resolved in a single visit. If your heat kicked off last night on Skyline Boulevard or near Carolands, you want a straight answer on cost and a real arrival window, not a callback queue. Dalton Heating & Air fixes furnaces across Hillsborough with written pricing before any work starts, a live person answering the phone 24/7, and a full-year written guarantee on every repair. Call (361) 306-9515 and you’ll get a real scheduler, not a recording.
Why Dalton Heating & Air Is Hillsborough’s Preferred Furnace Repair Company
Hillsborough homeowners call us because we hold to a standard most contractors in this area don’t even put in writing. Dalton Heating & Air is a Garrison Partners company, which means every job follows The Garrison Code: arrive inside the stated window, put the price in writing before touching a screwdriver, do the work by the book, clean up after ourselves, and stand behind the repair for 365 days. That’s not a warranty upsell. It’s the default on every call, from a quick ignitor replacement to a full heat exchanger job.
Marco Benitez, our service lead for Hillsborough, runs the crew to a simple rule: if the repair fails within a year, we return at no charge. No prorated parts, no trip fee, no argument. That matters in a town where homes sit on hillsides and furnace issues tend to reappear when temperatures drop. We also text you the technician’s name and photo before they arrive, so you know exactly who’s walking up your driveway.
Heat Pump Repair in Hillsborough
Heat pump repair in Hillsborough is a call we get more often as newer construction, particularly the homes built around Trousdale Drive and the lower slopes, replaced older gas furnaces with all-electric systems. A heat pump that isn’t holding temperature in winter usually points to a failing reversing valve, a refrigerant leak, or a defrost board that has stopped cycling. Hillsborough’s foggy mornings and damp winters mean the outdoor coil gets a workout, and any strain on the system shows up first as uneven heat or a system that runs constantly without reaching set temperature. Most heat pump repairs in Hillsborough fall between $150 and $700, depending on the component.
Refrigerant and Reversing Valve Work
When a heat pump won’t switch between heating and cooling, the reversing valve is often the culprit. Our techs test the valve’s solenoid and coil before replacing anything, because a dead solenoid is a $200 fix while a new valve runs higher. In Hillsborough, where many systems are zoned and running different temperatures room to room, we also check that auxiliary heat strips aren’t kicking on unnecessarily and driving up your bill.
Defrost and Coil Service
Fog sitting over Hillsborough’s canyons means outdoor coils collect moisture that freezes overnight. A failed defrost sensor leaves the coil iced over and the heat pump blowing lukewarm air. We diagnose the sensor, test the defrost timer, and clear any coil ice before it damages the fan blades. The price stays within the $150 – $700 range, and we hand you a written quote before any part gets ordered.
Heating Repair in Hillsborough
Heating repair in Hillsborough covers furnaces, heat pumps, and the ductwork decisions that come with homes built from the 1920s through the 2000s. When a furnace loses ignition on a cold night near Burlingame Country Club, the fix is usually an ignitor, flame sensor, or gas valve, and most of those repairs land in the $150 – $450 range here. Larger jobs, like a cracked heat exchanger or blower motor replacement on a high-end Trane or Lennox system, run toward the upper end of the $150 – $700 spectrum. Every price is in writing before work starts.
Ignitor and Gas Valve Replacement
Older furnaces in Hillsborough ran on standing pilot lights, but most homes have since converted to hot surface ignitors that fail every 8 – 12 years. If your furnace clicks but won’t light, that’s usually the ignitor failing to glow. Gas valve replacement is less common but shows up in homes where either the valve’s internal regulator has worn out or debris from old gas lines has fouled the seat. We stock common ignitor and valve parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so Hillsborough calls rarely wait on a part order.
Blower Motor and High-Limit Switch Work
Hillsborough’s ductwork, much of it retrofitted into older homes, tends to run undersized for the furnaces installed with it. High static pressure makes the blower motor work harder than it was designed to, and capacitors and motors fail sooner as a result. We measure static pressure on every heating call, not just when the motor has already seized. That test catches a failing capacitor before it takes the motor out with it; a $40 part is a lot cheaper than a $600 blower motor.
Trusted Brands We Service in Hillsborough
Dalton Heating & Air technicians are factory-trained on nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We carry common replacement parts for these systems in our trucks when we head into Hillsborough, which cuts the time between diagnosis and repair. For less frequent parts, our San Francisco Bay Area supply chain and dispatch office coordinates overnight turnaround, so you’re rarely waiting more than a day. If it’s a Trane heat pump with a failed defrost board or a Rheem furnace with a worn inducer motor, we’ve likely got the part on the van.
Common Furnace Repair Problems We See in Hillsborough Homes
- Blocked flue and intake vents from oak and redwood litter. Hillsborough’s mature tree canopy drops leaves, needles, and debris directly onto flue terminations and combustion air intakes. A blocked flue starves the burner, causing short-cycling and stress on the heat exchanger.
- Undersized returns and high static pressure. Many Hillsborough homes were built before central air standards existed, and their return ducts are too small for the furnace tied to them. The blower motor overworks, capacitors fail, and motors burn out years early.
- Oversized furnaces short-cycling through the heat exchanger. Furnaces installed without a proper load calculation are often 20 – 40% oversized for Hillsborough’s mild winter climate. They heat too fast, shut off, and cycle again, which stresses the heat exchanger and wastes fuel.
- High-limit switch trips from restricted airflow. When filters clog, returns are undersized, or vents are blocked, the high-limit switch trips to protect the furnace from overheating. It’s a symptom, not a disease, and the root cause matters more than resetting the switch.

FAQs About Furnace Repair in Hillsborough
No, you don’t need a load calculation just to repair a furnace. A load calculation, called a Manual J, determines the correct furnace size for a new installation. What you do need before a repair is a proper diagnosis, which is why we test static pressure, temperature rise, and combustion air on every heating call in Hillsborough. If the furnace was oversized from the start, we’ll tell you, because that affects whether repairing an aging heat exchanger is money well spent.
Most furnace repairs in Hillsborough run $150 – $700, with simple parts like ignitors and flame sensors at the lower end and blower motors or heat exchangers at the higher end. A tune-up runs $80 – $200. The exact number depends on which part failed and which brand of furnace you have. Call (361) 306-9515 for a free, written estimate before any work starts.
We use a simple framework: if the repair is under $700 and the furnace is under 12 years old, repairing usually makes sense in Hillsborough’s mild climate. If the heat exchanger is cracked or the system is over 15 years old and you’re also seeing higher gas bills, replacement might be the better call. Marco Benitez and the Dalton team will give you an honest read, not a sales pitch, and the repair-or-replace estimate is always in writing.
For Hillsborough’s mild winters and cool, foggy summers, a heat pump with a SEER2 rating of 16 or higher will likely keep energy bills flat compared to older systems. Furnaces are measured by AFUE rather than SEER2; an AFUE of 95% or better is the practical ceiling for our climate. Higher efficiency ratings pay off more slowly in Hillsborough than in hotter inland zones, so we’ll run the numbers before recommending equipment.
Short-cycling in Hillsborough usually traces to three causes: a blocked flue or intake from oak and redwood debris, an oversized furnace that heats the house too quickly, or a clogged filter choking airflow. On wooded lots near Skyline Boulevard, we find restricted combustion air more often than anywhere else in the Bay Area. The fix depends on which cause we find, and we’ll show you the test results before recommending work. Call (361) 306-9515 and we’ll dispatch a tech to Hillsborough today.
