Heating Repair in Commerce, CA

The short answer

AllPro HVAC repairs gas furnaces, heat pumps, and wall heaters in Commerce homes, starting with a diagnosis of the actual fault before recommending parts. If repair no longer makes sense, we explain how local furnace emissions rules and utility rebates affect a replacement. We also offer 24/7 emergency service.

Commerce winters are mild, so many furnaces and heat pumps sit idle for months and then get switched on during the first cold night. That is when weak igniters, dusty burners, clogged filters, and tired blower motors show up. AllPro HVAC Services repairs heating systems in Commerce homes in ZIP code 90040, about 8 miles southeast of our Los Angeles base. We find the actual cause of the problem, explain it in plain terms, and fix it so your home stays comfortable through the cool months.

Common Heating Problems in Commerce Homes

Los Angeles has a Mediterranean climate with dry summers and mild winters. Heating systems in Commerce often run only on cool evenings and early mornings. Long idle stretches let dust settle on burners and sensors and let small electrical problems go unnoticed until the heat is needed.

These are the problems we see most often on heating calls:

  • Furnace runs, but the air coming out is cool or lukewarm
  • Igniter clicks or glows, but the burners never light
  • Burners light and then shut off after a few seconds
  • Burning-dust smell that does not fade after the first few minutes
  • Blower that will not start, or that runs nonstop
  • Heat pump stuck in cooling mode, or iced up on cool mornings
  • Thermostat that does not respond or reads the wrong temperature
  • Rattling, banging, or squealing from the furnace closet, attic, or garage

How We Diagnose and Repair Your System

We start by asking what you have noticed and when it began. Then we check the system step by step: thermostat signals, power and safety switches, filter and airflow, ignition sequence, flame sensor, gas pressure, blower operation, and venting. On heat pumps, we also check the reversing valve, defrost controls, and outdoor coil.

Once we find the fault, we explain what failed and why, and we tell you what the repair involves before we start. Many problems come down to a single part, such as a flame sensor, igniter, pressure switch, capacitor, or control board. We also look for anything else that could cause the system to fail again soon, so you are not calling us back for the same issue.

Safety Comes First With Gas Heat

Many Commerce homes heat with natural-gas furnaces or wall heaters. A cracked heat exchanger, blocked flue, or poor combustion can let carbon monoxide into living spaces. If you smell gas, leave the house and call your gas utility from outside. If a carbon monoxide alarm sounds, get everyone outside and get help before anyone goes back in.

During every gas heating repair, we check venting and combustion. If we find a safety hazard, we tell you directly and explain the options for fixing it.

Repair or Replace: What Commerce Homeowners Should Know

When an older furnace needs major repairs over and over, replacement may be the better choice. In the Los Angeles region, South Coast AQMD Rule 1111 limits NOx emissions from natural-gas fan-type central furnaces sold and installed here. The district has been amending the rule toward zero-emission requirements and sets and revises the compliance dates. Before you choose a replacement, check the current rule. We can walk you through how it applies to your home.

Some homeowners choose an electric heat pump instead. Rebates depend on the utility that serves your address. Commerce is outside the City of Los Angeles, and many homes outside the city are served by Southern California Edison rather than LADWP. We confirm the current offer for your address before we quote it. The federal 25C tax credit for heat pumps applied only to equipment placed in service before December 31, 2025. It is not available for new installations after that date.

FAQ

Common questions

Don’t see your question? Call (213) 444-2507 and we’ll talk it through.

Why does my furnace smell like burning when I first turn it on?

Dust settles on the burners and heat exchanger during the warm months, and it burns off when the furnace first runs. A smell that fades within a few minutes is usually normal. If it lingers, smells electrical, or smells like gas, turn the system off and call for service.

My furnace lights and then shuts off. What causes that?

A dirty or failing flame sensor is a common cause. Other possibilities include a blocked vent, a faulty pressure switch, or a restricted filter that causes overheating. We test each of these to find the actual fault.

Do you repair heat pumps as well as gas furnaces?

Yes. We repair heat pumps, gas furnaces, and wall heaters in Commerce homes. On heat pumps, we check heating mode operation, defrost controls, refrigerant-side issues, and the outdoor unit.

Can I get a utility rebate if I replace my furnace with a heat pump?

It depends on which utility serves your address. Many homes outside the City of Los Angeles, including in Commerce, are served by Southern California Edison rather than LADWP. We confirm the current rebate offer for your address before quoting it.

Is the federal tax credit for heat pumps still available?

No, not for new installations. The federal 25C credit covered qualifying heat pumps placed in service before December 31, 2025.

Do you offer emergency heating repair in Commerce?

Yes. AllPro HVAC Services offers 24/7 emergency service in Commerce and nearby communities, including Bell, Maywood, Vernon, Monterey Park, and Huntington Park.
