When your furnace quits on a cold Santa Clarita night, you need a technician who shows up, diagnoses the problem, and puts the price in writing before turning a single wrench. That’s how Dalton Heating & Air Santa Clarita has run every furnace repair since 2003. Most Santa Clarita Furnace Repair calls run $150 – $700 depending on the part, and our technicians arrive in uniform, background-checked, and factory-trained on nine major brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Call (661) 621-3712 and a live person answers, 24/7, not a voicemail queue.
Furnace Maintenance
Furnace Maintenance is scheduled service that keeps your heating system from failing during the months you need it most. In Santa Clarita’s high desert climate, furnaces work hard through cold valley nights, and dust from the surrounding hills coats internal components faster than homeowners expect. Dalton Heating & Air Santa Clarita performs a full inspection, cleaning, and safety check for $80 – $200 per visit, with a written report of what we found and what needs attention. Skipping this service is how a $200 fix becomes a $700 repair in January. We recommend scheduling once a year, ideally in early fall before the first cold snap hits Stevenson Ranch and the surrounding foothills.
Seasonal Readiness Check
We test the ignition sequence, measure gas pressure, and verify the heat exchanger is intact. This takes about an hour on most systems and catches small problems before they become no-heat emergencies. A furnace that runs cleanly uses less gas, which matters when Santa Clarita utility rates climb in winter.
Filter and Airflow Inspection
A clogged filter makes your blower motor work harder and can trip the high-limit switch. We check static pressure and replace standard filters during the visit. In homes around Porter Ranch and Granada Hills with pets or recent construction nearby, we often recommend more frequent filter changes.
Styles & brands we work with
Heat Pump Repair
Heat Pump Repair covers systems that both heat and cool by moving heat rather than burning fuel, which is common in newer Santa Clarita homes without gas lines. When a heat pump fails in heating mode, the symptom is usually cold air blowing from the vents or the outdoor unit running constantly without raising indoor temperature. Repairs typically run $150 – $650 depending on whether the issue is electrical, refrigerant-related, or a failed reversing valve. Dalton Heating & Air Santa Clarita technicians carry diagnostic gauges and multimeters to isolate the problem in one visit, then hand you a written price before any work starts.
Reversing Valve and Defrost Issues
The reversing valve is the component that switches your heat pump between heating and cooling. When it sticks, the system may heat when you want cooling or vice versa. In Santa Clarita’s temperature swings, a failed defrost cycle causes the outdoor coil to ice over on cold mornings, which is a call we handle regularly in the Castaic and Stevenson Ranch areas.
Refrigerant Leak Detection
Low refrigerant, the cooling fluid your system needs to reach set temperature, usually points to a leak somewhere in the line set or coil. We use electronic leak detectors and bubble testing to find the source before recharging. Guessing is not a repair method, and a recharge without finding the leak is money wasted.
Heating Repair
Heating Repair is the broad category covering any problem with a furnace, heat pump, or ducted heating system that keeps your home from reaching set temperature. If your system is short cycling, making grinding noises, or blowing lukewarm air, those are heating repair calls. Most fall between $150 and $700, with electrical components like igniters, flame sensors, and control boards on the lower half and blower motors or gas valves on the upper end. We service all nine major residential HVAC brands and stock common parts for Goodman, Rheem, and York units on our trucks.
Electrical and Control Board Diagnosis
Modern furnaces depend on control boards that interpret signals from the thermostat, flame sensor, and limit switches. When a board fails, the system may refuse to start or shut down mid-cycle. We trace voltage through the circuit rather than swapping parts blindly, which saves Santa Clarita homeowners money and repeat visits.
Blower Motor Replacement
A failing blower motor often announces itself with a high-pitched whine or a burning smell. If the motor seizes, your furnace heats but can’t push air through the ducts. We replace both standard and ECM motors with OEM or equivalent parts and balance the wheel before we leave.
Boiler Repair
Boiler Repair involves hydronic heating systems that circulate hot water through radiators or baseboards instead of forcing air through ducts. While less common in Santa Clarita than forced-air furnaces, some older homes in San Fernando and Northridge were built with boilers, and they develop their own set of problems. Common issues include failing circulator pumps, air-locked pipes, and expansion tank failures, with most repairs landing between $150 and $700. Our technicians are factory-trained to diagnose boiler systems and we write the price down before any parts are ordered or installed.
Circulator Pump and Zone Valve Service
The circulator pump moves hot water from the boiler through your piping. When it fails, you get cold radiators even though the boiler fires. Zone valves control which rooms get heat, and a stuck valve can leave one part of the house cold while another overheats. Both repairs are straightforward for a trained tech and should be done the same visit.
Expansion Tank and Pressure Problems
An expansion tank absorbs pressure changes as water heats and cools. When it fails, the pressure relief valve may drip constantly or the system may shut down on high pressure. We check the tank’s air charge with a pressure gauge and replace it if the bladder has failed, usually the same day.
Gas Furnace Repair
Gas Furnace Repair addresses furnaces that burn natural gas or propane, which covers the majority of heating systems in Santa Clarita. Symptoms range from a furnace that won’t ignite to one that lights and then shuts off after a few seconds. Repairs generally run $150 – $700, with igniters, flame sensors, and thermocouples on the lower end and gas valves or heat exchangers higher. Dalton Heating & Air Santa Clarita prioritizes gas furnace calls because a malfunctioning burner can produce carbon monoxide, and we test gas pressure and combustion on every call, not just when something is visibly wrong.
Igniter and Flame Sensor Replacement
Hot surface igniters glow orange to light the gas. Over time they crack or burn out. A dirty flame sensor tells the control board there’s no flame even when the burner is lit, causing the furnace to shut down seconds after ignition. Both are common repairs we complete in a single visit, often with parts on the truck.
Gas Valve and Burner Service
If the gas valve fails, the furnace gets no fuel. If the burners are corroded or misaligned, the flame is uneven and inefficient. We inspect the manifold, clean burners where possible, and replace gas valves with proper calibration so the system fires reliably and safely. Never attempt gas work as a DIY project. A mistake can leak gas into your home, and that risk is not worth the savings.
Furnace Tune Up
Furnace Tune Up is preventive maintenance that runs $80 – $200 and is designed to catch failures before they happen, not after. In Santa Clarita, we book most tune-ups between September and November as homeowners prepare for the cold season. The visit includes a combustion analysis, thermostat calibration, safety inspection, and a written report with photos. Dalton Heating & Air Santa Clarita technicians are not paid on what they sell, so when we flag a repair, it’s because the system needs it, not because someone is working on commission.
Combustion Analysis and Carbon Monoxide Check
We use a digital combustion analyzer to measure oxygen, carbon monoxide, and flue temperature. This tells us if the furnace is burning fuel completely or wasting gas and producing dangerous byproducts. A healthy furnace runs clean. One that doesn’t needs attention before the heating season starts.
Thermostat and Safety Control Verification
We test the thermostat for accurate temperature readings and check every safety switch, including the high-limit switch, rollout switch, and pressure switch. These components shut the furnace down when something is wrong. Confirming they work is the difference between a minor fix and a house fire, and we take that seriously on every tune-up in Santa Clarita.
Emergency Furnace Repair
Emergency Furnace Repair is same-day service for furnaces that fail on the coldest nights or the busiest mornings. Dalton Heating & Air Santa Clarita answers the phone with a live person 24 hours a day, 7 days a week, and we dispatch technicians to Santa Clarita, San Fernando, and Castaic with no overtime charge for emergency calls. If your furnace is blowing cold air or refusing to start, don’t wait until morning. Cold indoor temperatures are dangerous for infants, seniors, and anyone with respiratory issues. Most emergency furnace repairs fall between $150 and $700, and the price goes in writing before we touch anything.
Same-Day No-Heat Response
When you have no heat, our team prioritizes your call. In most cases, we can have a technician at your door the same day, often within hours of your call. We stock the most common failure parts on our trucks so many Santa Clarita emergency calls are fixed in one visit.
Winter Storm and Cold Snap Coverage
Santa Clarita’s cold snaps catch furnaces that have been idle all year. When temperatures drop, our phone lines get busy, and we staff extra technicians to handle the volume. If you’re in Stevenson Ranch, Porter Ranch, or Sylmar and your furnace fails overnight, call (661) 621-3712. A real person picks up.
Brands We Service
Dalton Heating & Air Santa Clarita is factory-trained on nine major residential HVAC brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Our technicians know the failure patterns specific to each brand. Goodman furnaces, for instance, are workhorses but their igniters tend to burn out after several seasons. Rheem units are common in Santa Clarita track homes, and we see a fair share of pressure switch issues as they age. York systems often need attention on their control boards around the ten-year mark.
Beyond the common brands, our experience in the field means we can diagnose and repair most makes without making you wait for a specialist. We carry OEM parts for the brands we service most, and for everything else, we source parts locally so your repair doesn’t stall. Whether you have a Daikin heat pump, a Goodman furnace, or anything else, we can help. If you need Furnace Repair in San Fernando, we cover that area too.

- Yellow or flickering burner flame – A healthy gas furnace burns with a steady blue flame. Yellow or orange flames indicate incomplete combustion, which can produce carbon monoxide. Shut the system down and call a furnace professional immediately.
- Furnace lights then shuts off after a few seconds – This is called short cycling, and it usually points to a dirty or failed flame sensor. The furnace thinks the flame went out and shuts off as a safety measure. It’s a quick fix, but ignoring it strains the system and leaves you without reliable heat.
- Grinding, squealing, or banging sounds – A grinding noise often means a failing blower motor bearing. Banging could be a delayed ignition in the burner chamber. Neither resolves itself. Both get more expensive the longer they run.
- Cold air blowing from your vents – If your furnace runs but the air is cold, the burners may not be lighting, or the heat exchanger could be cracked. Either way, this is not a filter problem. Call for a diagnosis, not a YouTube tutorial, especially with gas involved.
- Rotten egg smell near the furnace – Natural gas is odorized to smell like rotten eggs. If you smell it, leave the house immediately and call your utility company first, then call us. Do not flip light switches, use your phone inside, or start your car in the garage. Gas leaks are emergencies, and the proper sequence saves lives.
Our Process, Step by Step
- 1
Call and talk to a live person – You call (661) 621-3712 and speak with a real dispatcher, not a machine. We log your address, ask what the furnace is doing, and give you a straight answer on when a technician can arrive. No callback windows. No waiting for a text.
- 2
Diagnosis with documented findings – The technician arrives in a marked Dalton Heating & Air vehicle, in uniform, and inspects the system. We test gas pressure, check electrical connections, and use diagnostic tools to pinpoint the failure. You get a clear explanation of what’s wrong in plain language, using trade terms and then explaining them, like “your thermocouple, which is the safety sensor that confirms the pilot flame is lit, has failed.”
- 3
Written price before any work starts – Before a single part is ordered or any repair begins, you get the total price in writing. That’s The Garrison Standard, active since 2003. If the job requires a part we don’t have on the truck, we tell you when it will arrive and what the cost is. No surprises at the door.
- 4
Repair completed by the book – The technician performs the work to manufacturer specifications, following code and safety standards. For gas furnace repairs, we verify combustion readings and test every safety switch after the repair. For electrical work, we check voltage and amperage. The job isn’t done until the system runs correctly and safely.
- 5
Clean site and written guarantee – We leave your furnace area cleaner than we found it, walk you through what we did, and hand you a written guarantee covering the repair for a full year. If the same part fails within 365 days, we return at no charge. That’s the 365-Day Done Right Promise, and it’s included on every repair, not sold as an upgrade.
