AfterFast, Reliable Furnace Repair Across Fresno
Furnace repair in Fresno typically costs $150 – $700 depending on the part that failed, and most jobs are completed same-day when the call comes in before noon. We’re Dalton Heating & Air, and our Furnace Repair team works throughout Fresno, from Fig Garden to Tower District to the newer subdivisions off Herndon Avenue. If you’re getting no heat, short cycling, or a burner that lights and then kicks off, call (361) 306-9515 and a live person answers. Not a voicemail tree. The price goes in writing before we touch a single component.
Why Dalton Heating & Air Is Fresno’s Preferred Furnace Repair Company
Fresno homeowners call us because they’ve been burned before. A technician misses the window, quotes $89, then finds $900 in “additional work” once the furnace is apart. The Garrison Standard exists to make that disappear. Since 2003, every Dalton Heating & Air job has run on the same terms: written price before work begins, written guarantee on every repair, and a free return visit if the repair fails within the guarantee period. Marco Benitez runs our Fresno operation and holds every tech to The Garrison Code: arrive inside the stated window, do the job by the book, clean up, and stand behind the work for a full year.
Our technicians are background-checked, uniformed, and factory-trained on nine major HVAC brands. When you book, you get a name and a photo before the truck rolls. The 365-Day Done Right Promise covers every repair we make in Fresno. If it’s not done right, we make it right. That’s the standard, not a marketing line.
Furnace Maintenance in Fresno
Furnace Maintenance in Fresno runs $80 – $200 and is the single best defense against the inversion-season failures we see every winter. A tune-up here isn’t a filter swap. It’s a combustion-air inspection, a heat exchanger check, a static pressure reading, and a flame sensor and ignitor test, all documented in a written report you keep. Valley dust and winter fog coat ignition assemblies and clog evaporator coils faster than almost anywhere else in the state, so skipping maintenance in Fresno means a breakdown will find you, usually on the coldest week of January.
Combustion Air and Heat Exchanger Inspection
Fresno’s San Joaquin Valley air traps winter inversion fog and smoke for days at a time. That means furnaces here pull restricted combustion air far more often than coastal or Sierra properties. Our maintenance visits include a specific check for flame rollout and heat exchanger stress because those are the exact failure modes restricted air creates.
Ignitor and Flame Sensor Testing
We test the hot-surface ignitor and clean the flame sensor on every Fresno tune-up. Airborne particulate from inversion season coats these parts and causes failures that strand homeowners on 34-degree mornings. A five-minute test catches the fault before it catches you.
Heat Pump Repair in Fresno
Heat Pump Repair in Fresno runs $150 – $700, and it’s increasingly common as homeowners in Clovis and northeast Fresno replace aging furnaces with dual-fuel or all-electric heat pump systems. A heat pump heats and cools, so when it fails in winter, you lose both. The most common culprit we see in Fresno is a weak capacitor on the outdoor unit. It’s a $20 part that mimics a compressor failure and leaves the system dead. We test capacitors on every call and replace them when they’ve drifted below spec.
Refrigerant and Reversing Valve Checks
Refrigerant is the working fluid that moves heat into your home. A low charge from a slow leak drops heat output fast. We check pressures, find leaks with an electronic detector, and repair the source, not just top off the system.
Defrost Board and Sensor Diagnostics
When a Fresno heat pump ices over in cold, damp conditions, the defrost board should cycle the system out of heating to melt the coil. A failed board or sensor locks the outdoor coil in ice. We bench-test boards and verify sensor resistance before recommending replacement.
Trusted Brands We Service in Fresno
We service Trane, Lennox, Goodman, Rheem, and five other major HVAC brands with factory training and locally stocked parts. That matters in Fresno because a Trane gas valve behaves differently than a Goodman, and ordering parts by VIN-style serial lookup beats waiting a week for the wrong board. Our trucks carry the high-failure components for Fresno’s climate: ignitors, flame sensors, capacitors, pressure switches, and blower motor modules. Most repairs finish in one visit.
Common Furnace Repair Problems We See in Fresno Homes
- Cracked heat exchangers from restricted airflow. Fresno’s dust and pet hair clog evaporator coils and filters faster than most markets. Static pressure climbs, the heat exchanger runs hotter than design, and cracks form above the burners.
- Failed hot-surface ignitors and flame sensors. Winter inversion fog and airborne particulate coat the ignition assembly. The ignitor fails, the sensor won’t prove flame, and the system locks out on a cold morning.
- Oversized replacement furnaces in older housing stock. Fig Garden and Tower District bungalows with leaky single-pane windows and uninsulated attics get rule-of-thumb replacements that are too big. Short cycling, high bills, and early heat exchanger failure follow.
- Weak capacitors on heat pump outdoor units. A capacitor drifts, the compressor or fan won’t start, and the homeowner thinks the compressor is dead. We test first and replace the $20 part before it becomes a $2,000 diagnosis.
Pricing for Furnace Repair in Fresno, CA
Here’s the honest math for Fresno. A standard repair with diagnostic, parts, and labor runs $150 – $700. The full line-item breakdown is below.

What We See in Fresno That a Generic Contractor Misses
Fresno’s San Joaquin Valley air traps winter inversion fog and smoke, so furnaces here run with restricted combustion air far more often than the coast or Sierra foothills. Our combustion-air and heat exchanger checks on Fresno furnaces are built around that reality. A Bay Area or Tahoe crew simply doesn’t prioritize the failure modes our techs see weekly because their air moves. Ours sits. We got a no-heat call off Van Ness Boulevard near Fresno High where the homeowner’s 22-year-old Carrier furnace would light, run 90 seconds, then trip the high-limit switch. The heat exchanger had cracked above the burners, and our static pressure reading showed 0.9 in. w.c., nearly double the design rating, because a clogged evaporator coil from years of Valley dust was choking airflow. We showed the homeowner the crack, ran a load calculation, and replaced the 80% furnace with a properly sized 96% two-stage unit matched to their existing ductwork. That’s the kind of repair you only get from a crew that works in Fresno year-round.

FAQs About Furnace Repair in Fresno
The high-limit switch trips when the furnace gets too hot, and in Fresno it’s almost always airflow. Valley dust and pet hair clog the evaporator coil or filter, static pressure rises, and the heat exchanger can’t shed heat. We measure static pressure on every call and correct the airflow problem rather than just resetting the switch. Call (361) 306-9515 for a diagnosis, and the price is in writing before we start.
Use the multiplication rule: if the repair cost times the furnace age exceeds $5,000, replacement usually wins. A $400 repair on a 22-year-old unit is a bandage. A $400 repair on a 7-year-old furnace is a sound decision. We’ll show you the failed part and the numbers either way, and we’ll never push replacement when repair makes sense. Call (361) 306-9515 and we’ll walk you through the math honestly.
A load calculation, also called a Manual J, measures your home’s actual heating demand: window area, insulation, orientation, and air leakage. In older Fresno neighborhoods like Fig Garden and Tower District, rule-of-thumb sizing often overshoots by 30% or more. That oversized furnace short cycles, wastes gas, and dies early. We run the calculation on every replacement quote, and the price is fixed before any equipment is ordered.
SEER2 is the updated efficiency rating for cooling, and because Fresno summers run long, it has a real effect on your bill even though this page is about heating. A SEER2 16 system uses about 20% less electricity to cool than a SEER2 13 unit. On a $300 summer bill, that’s roughly $60 a month back in your pocket. If you’re replacing a furnace and AC together, we’ll show the SEER2 math specific to your house and usage.
Because a weak capacitor mimics a compressor failure. The capacitor gives the compressor and fan motor the starting jolt they need. When it drifts below spec, the motor hums but won’t turn, and a homeowner hears “dead compressor” when the actual fix is a $150 – $250 part. We test capacitors on every heat pump call in Fresno and replace them before they strand you on a cold night. Call (361) 306-9515 with any heat pump issue, and a live person answers.
