AfterTrusted Furnace Repair Nationwide
Furnace repair means getting your heat back on when a burner won’t light, a blower won’t spin, or a thermostat stops talking to the unit. Brandt HVAC has handled this work since 2003 as part of the Threshold Group family of home-service companies, and we still do it the old way: a written price before any work starts, a live person on the phone, and a repair that’s guaranteed in writing. Most our Furnace Repair in Los Angeles jobs run $150 – $700, and our technicians carry common parts on the truck for same-day fixes. If your furnace is acting up, call (984) 538-9003 and talk to a real person right now.
Furnace Maintenance
Furnace Maintenance is the scheduled service that keeps a heating system running before it breaks, not after. Brandt HVAC recommends it once a year, ideally in early fall, before the first cold snap puts real demand on the equipment. During a maintenance visit we inspect the heat exchanger, test the ignition system, check gas pressure, clean the flame sensor, and replace or clean the air filter. You get a written report of what we found and what it means. A furnace tune-up typically runs $80 – $200, and it catches the small stuff before it becomes a $700 repair.
What a Maintenance Visit Covers
We test the full startup sequence from thermostat call to burner ignition. That includes checking the safety switches that shut the system down if something goes wrong. We also measure the temperature rise across the heat exchanger, which tells us how efficiently the furnace is moving heat into your home.
Why Once a Year Is the Right Interval
Gas furnaces produce condensation and combustion byproducts that build up over a heating season. A dirty flame sensor is the most common cause of a furnace that starts and then quits after a few seconds. Annual service keeps that sensor clean and catches cracked heat exchangers before they become a carbon monoxide risk.
Heat Pump Repair
Heat Pump Repair addresses a system that both heats and cools your home by moving heat from one place to another rather than burning fuel. When a heat pump fails in heating mode, it’s usually the reversing valve, the outdoor defrost board, or low refrigerant, and Brandt HVAC diagnoses all of it. Our technicians work on every major residential brand and arrive with the test equipment to find the fault without guessing. You’ll get a written price before we touch anything, and most heat pump repairs fall in the $150 – $650 range we use for cooling and heating equipment work.
Heat Pump Systems That Run Constantly
A heat pump that never shuts off is often low on refrigerant or fighting a failing defrost cycle. We measure subcooling and superheat to know which one it is before we recommend anything. Guessing at a heat pump costs you money; measuring does not.
Cold Air Coming From Your Vents in Heat Mode
This usually means the system is stuck in cooling mode or the auxiliary heat strips aren’t engaging. The fix can be as simple as recalibrating the thermostat or replacing a reversing valve solenoid. Either way, we’ll show you the test results and the fixed price before work begins.
Heating Repair
Heating Repair is the broad term for fixing any part of the system that warms your home, whether it runs on gas, electricity, or a heat pump, and it’s worth reading DIY vs Professional Furnace Repair: What’s Safe to Do Yourself before deciding how to proceed. Brandt HVAC treats every heating repair the same way: diagnose the real cause, write the price down, and do the work only after you approve it. The most common heating repairs we make are failed igniters, dead blower motors, faulty limit switches, and control boards that won’t respond. Most heating repairs cost $150 – $700, and we carry the parts that fail most often so we can finish the job in one visit.
All-Electric Heating Systems
Electric furnaces and air handlers fail differently than gas units. We see burned-out heating elements, failed sequencers, and tripped high-limit switches. These repairs are often straightforward, but the wiring carries real voltage, so we test everything with the power off before we open a panel.
Older Systems With Original Parts
If your furnace is 15 years old or more, we’ll check whether the failed part is still available and worth installing. Some original control boards are obsolete, and we’ll tell you honestly if a repair is throwing money at a system that’s near the end. The decision stays yours, but you’ll have real numbers to make it.
Boiler Repair
Boiler Repair covers hydronic heating systems that heat water and circulate it through radiators or baseboards. Brandt HVAC services residential boilers including gas and electric models, and we diagnose problems at the circulator pump, pressure relief valve, expansion tank, and aquastat. A boiler that loses pressure or makes banging noises needs attention fast, because the fix is usually cheaper before water damage spreads. Boiler repairs typically fall in the $150 – $700 range depending on the part and how long it takes to reach it.
Low Boiler Pressure and Kettling Noises
Low pressure usually points to a leak or a failed expansion tank, while a banging or kettling sound means sediment has built up on the bottom of the heat exchanger. We check the expansion tank’s air charge and test the pressure relief valve during every boiler call. Catching a bad relief valve early prevents a flooded mechanical room.
Radiator and Baseboard Trouble
Cold spots in radiators usually mean trapped air or a balancing problem, not a failing boiler. We bleed the system and check that each zone is getting proper flow before we condemn any equipment. Sometimes the fix is ten minutes with a bleed key, and we’ll tell you that instead of selling you a part you don’t need.
Gas Furnace Repair
Gas Furnace Repair is the work of fixing furnaces that burn natural gas or propane to heat your home, as detailed in The Complete Furnace Repair Guide for Los Angeles Homeowners. Brandt HVAC handles igniter replacements, gas valve failures, flame sensor cleaning, burner assembly problems, and heat exchanger inspections on every common residential brand. Our technicians are trained on the combustion analyzer readings that tell us whether the burn is clean and safe. Most gas furnace repairs cost $150 – $700, and the written guarantee tells you exactly what’s covered and for how long, including a free return visit if the repair fails.
Carbon Monoxide and Combustion Safety
A cracked heat exchanger can leak carbon monoxide into your home, and we inspect for it on every gas furnace call. If we find a crack, we’ll show you the evidence and shut the system down with your permission. This is the one repair where waiting is never worth the gamble, and we treat it that seriously.
Igniters and Flame Sensors
Hot surface igniters are a wear item on modern gas furnaces, and they usually fail at the worst possible moment. A failed igniter means the furnace won’t light at all, while a dirty flame sensor means it lights and then shuts off in seconds. Both are common, and both are usually fixable on the first visit.
Furnace Tune Up
A Furnace Tune Up is a preventive service visit that gets your heating system ready for winter, and Brandt HVAC prices it between $80 – $200. We clean the flame sensor, test the igniter, check gas pressure, inspect the heat exchanger, and measure the temperature rise. You’ll get a written report of what we found and what’s wearing down, so you can plan before you’re surprised. The best time to schedule is late summer or early fall, before the equipment has run for months without attention.
The Tune-Up Checklist
Our tune-up runs through the manufacturer’s own service checklist for your specific brand and model. That includes checking the condensate drain for blockages, testing the limit switches, and verifying that the blower wheel is clean and balanced. We also test the thermostat calibration so your furnace isn’t running longer than it should.
After the Tune-Up Report
If we find something that needs repair, you get a written quote and time to decide. Our technicians are not paid on what they sell, so the report is just the facts. You’ll know what is urgent, what can wait, and what looks fine.
Emergency Furnace Repair
Emergency Furnace Repair is the service you need when the heat goes out on the coldest night of the year and you can’t wait for a scheduled appointment. Brandt HVAC answers the phone with a live person 24 hours a day, 7 days a week, including nights, weekends, and holidays. We’ll tell you who is coming, send their name and photo before they arrive, and give you a written price before any work starts, even at 2 a.m. Emergency furnace repairs run the same $150 – $700 range, with no overtime charge for the call.
What Counts as an Emergency
No heat during freezing weather is an emergency, and so is a gas smell or a furnace that won’t shut off. If you have young children, elderly family members, or anyone with a health condition in the home, don’t wait until morning. Call us and we’ll talk through what you’re seeing and whether it’s safe to stay in the house.
What Happens When You Call at Night
You’ll speak to a person, not a voicemail tree. They’ll ask what you’re seeing, listen to you describe the symptoms, and dispatch a technician with the parts most likely to match the problem. Every technician arrives in uniform, shows a photo ID badge at the door, and is someone you were told to expect by name.
Brands We Service
We service Carrier furnaces and heat pumps every week, and our technicians know the brand’s control board quirks and common failure points. We’ve worked on Carrier units across every major configuration, from gas furnaces to all-electric air handlers, and we stock the OEM parts that fail most often.
We’ve also serviced hundreds of Trane and Goodman systems, which gives us a good read on which repairs hold up and which ones signal a unit that’s nearing retirement. We work on Daikin and Bryant equipment regularly as well. Whether you have one of these brands or any other make, we can help.
Signs You Need a Pro Right Now
- Your furnace runs but won’t produce heat. The burner may not be lighting, or the gas valve may not be opening. If you hear the blower running and feel only cold air, something in the ignition sequence has failed.
- You smell gas or a burning odor. A gas smell means call us and your utility company immediately. A burning smell that doesn’t go away can point to an overheating motor or wiring.
- The furnace turns on and off every few minutes. Short cycling usually means a dirty flame sensor, a failing limit switch, or an overheating heat exchanger. It wastes fuel and adds wear to every component.
- You hear banging, popping, or screeching. Banging can mean delayed ignition or expanding ductwork. Screeching usually points to a blower motor or belt that’s about to fail.
- Your energy bills jumped without a reason. A furnace that’s working harder than it should is often running longer or heating less. That inefficiency is usually traceable to a specific failing part.

How Much Does Furnace Repair Cost?
Most Furnace Repair in Huntington Park jobs run between $150 and $700, depending on what failed. A flame sensor cleaning or igniter replacement on a common brand typically lands in the $150 – $300 range, parts and labor included. A blower motor or control board replacement runs higher, usually $300 – $700, because the parts themselves cost more. A full furnace replacement is a different conversation, and we’ll give you honest numbers for that too.
The biggest factor in price is the part that failed and how long it takes to reach it. A simple flame sensor takes minutes; a heat exchanger replacement can take hours and involves real safety testing. The age of your furnace matters too. Parts for older units can be harder to source, and sometimes the right call is not to repair at all. We’ll tell you if a repair is throwing money at a furnace that should be replaced, and we’ll show you the math. Our estimates are free, the price is written before work starts, and you’ll never pay a cent you didn’t agree to in advance.
