Is Your Heater Doing Any of This?

Heater not turning on at all

The system does not respond to the thermostat - no sound, no airflow, no heat. Most common causes: failed igniter, tripped circuit breaker, pilot light outage, or a safety limit switch that has shut the system down. Diagnosable and repairable same day in most cases.

Heater running but blowing cold air

The system turns on and runs but delivers no warmth. In gas systems, this typically means ignition failure - the blower runs but the burner never fires. In heat pumps, it may indicate a refrigerant issue or a reversing valve failure. Do not run the system continuously - call for diagnosis.

Short-cycling - turns on and off repeatedly

The system fires and shuts off every few minutes without completing a full heating cycle. Common causes: dirty flame sensor, clogged filter triggering the safety limit switch, or an oversized system. Short-cycling accelerates wear on every mechanical component in the system.

Banging, booming, or rattling noise on startup

A loud bang when the heater fires is most commonly caused by delayed ignition - gas accumulates before igniting, causing a small explosion. This is a gas safety concern. Do not continue running a system that makes this noise. Call AIRONE immediately.

Heater not reaching the set temperature

The system runs continuously but the home never reaches the thermostat setpoint. Causes range from undersized equipment to a failing heat exchanger, blocked flue, low gas pressure, or significant duct leakage. Common in older SoCal homes during cold snaps.

Yellow, orange, or flickering pilot light

A healthy gas flame is blue. A yellow, orange, or flickering flame indicates incomplete combustion - potentially producing carbon monoxide. If your CO detector is sounding, leave the building and call 911 before calling AIRONE. If no CO alert, call AIRONE same day for a gas combustion inspection.

Burning smell from vents

A brief dusty smell at the start of heating season is normal - dust burning off the heat exchanger. A persistent burning smell, plastic odor, or smell of burning wire is not normal and should be diagnosed immediately. Shut the system off and call AIRONE.

Uneven heat - some rooms warm, some cold

Uneven heating is most often caused by duct imbalance, blocked registers, or a failing zone control system. In older LA homes with wall heaters, it may indicate a failing thermocouple or gas valve issue in a specific unit. Multiple causes - requires diagnosis to identify the root issue.

All Heating System Types AIRONE Services in Los Angeles

Los Angeles homes use a wider variety of heating systems than most US markets - partly because of the mild climate, partly because of the age and diversity of the housing stock. AIRONE services and repairs all of them.

Gas Furnace

The most common heating system in LA County. A forced-air gas furnace heats air and distributes it through ductwork. Most LA homes built after 1975 use a central gas furnace. Common repairs: igniter replacement, flame sensor cleaning, control board replacement, blower motor repair, heat exchanger inspection. AIRONE services all major gas furnace brands - same day in most areas. See our dedicated furnace repair page: Furnace Repair →

Wall Heater

Wall heaters are recessed gas units mounted in the wall - extremely common in pre-1980 Los Angeles apartments, condos, and mid-century homes. They operate independently of a central duct system. Common repairs: pilot light issues, thermocouple replacement, gas valve replacement, thermostat replacement, and burner cleaning. AIRONE services all major wall heater brands including Williams, Empire, Comfort Glow, and others.

Heat Pump - Heating Mode Failure

A heat pump provides both cooling and heating by reversing the refrigeration cycle. When a heat pump fails to heat, common causes are a failed reversing valve, low refrigerant charge, a defrost cycle malfunction, or outdoor unit issues in cold weather. Heat pump heating mode failures require a C-20 licensed technician with refrigerant handling certification. AIRONE diagnoses and repairs heat pump heating failures same day in most areas.

Electric Baseboard and Electric Wall Heaters

Electric resistance heaters - baseboards, electric wall units, and fan-forced electric heaters - are common in condos, apartments, and additions where gas is unavailable. Common repairs: failed heating element replacement, thermostat replacement, and wiring issues. AIRONE services electric heating systems across LA County, South Bay, and Orange County.

Package Unit - Heating Mode

Package units are all-in-one rooftop or ground-mount systems that provide both heating and cooling. Gas/electric package units have a gas burner section for heating. Heat pump package units use refrigerant-based heating. Common heating mode repairs: igniter failure, gas valve issues, heat exchanger problems, reversing valve failure (heat pump models). Common in flat-roof LA properties and commercial buildings. See Package Unit AC → for the cooling-side reference.

Floor Furnace

Floor furnaces are recessed gas units installed in the floor, covered by a floor grate. They were common in Los Angeles homes built in the 1930s–1960s. Many are still in use in older neighborhoods including Highland Park, Silverlake, Echo Park, and mid-city areas. Common repairs: pilot light issues, thermocouple replacement, gas valve service, and burner cleaning. Not all HVAC companies service floor furnaces - AIRONE does. Call (323) 471-1037.

Prices reflect typical Los Angeles market ranges for parts and labor as of 2026. Your exact cost depends on system type, brand, part availability, and repair complexity. AIRONE provides a flat-rate quote before any work begins - you are never charged more than the approved amount.

When does it make more sense to replace than repair your heating system?

As a general rule, if a repair costs more than 50% of a new system and the heater is over 15 years old, replacement is typically the better long-term investment. This applies to all system types - gas furnaces, wall heaters, and heat pumps. AIRONE technicians will tell you honestly which direction makes financial sense and provide written quotes for both options when the decision is close. For gas furnace replacement, reference: Furnace Installation →

Heater Repair Los Angeles - Frequently Asked Questions

Heater repair in Los Angeles typically costs $100–$400 for most common repairs such as thermocouple replacement, igniter replacement, and flame sensor cleaning. More complex repairs - gas valve replacement, control board replacement, or reversing valve replacement on heat pumps - typically cost $300–$900. AIRONE charges an $89 diagnostic fee applied toward the repair cost if you proceed, and provides a flat-rate quote before any work begins.
Most common heater repairs - thermocouple replacement, igniter replacement, flame sensor cleaning, and thermostat replacement - take 1–2 hours from diagnosis to completion. More complex repairs involving gas valve replacement, control board replacement, or heat pump reversing valve repair may take 2–4 hours. AIRONE technicians complete approximately 80% of heater repairs on the first visit.
The most common causes of a heater running without producing heat are ignition failure in gas systems - where the blower runs but the burner never fires - and reversing valve failure in heat pumps, where the system stays in cooling mode rather than switching to heating. Igniter failure and flame sensor issues are the most common and least expensive causes in gas systems. Call (323) 471-1037 for same-day diagnosis.
Short-cycling is most commonly caused by a dirty flame sensor that cannot confirm the burner is lit, a clogged air filter causing the furnace to overheat and trip the safety limit switch, or an oversized heating system. A dirty flame sensor is the most common and least expensive cause - cleaning or replacement typically costs $100–$200. Short-cycling causes accelerated wear and should be repaired promptly.
AIRONE repairs all residential heating system types including gas furnaces, natural gas wall heaters, floor furnaces, heat pumps in heating mode, electric baseboard heaters, electric wall heaters, and package units in heating mode. AIRONE also services propane heating systems in areas of LA County and OC without natural gas service. If you are unsure of your system type, describe the symptom when you call - the technician will identify the system on arrival.
Yes - AIRONE repairs natural gas wall heaters, which are common in pre-1980 Los Angeles apartments, condos, and mid-century homes. Common wall heater repairs include thermocouple replacement, pilot light service, gas valve replacement, and thermostat replacement. AIRONE services Williams, Empire, Comfort Glow, and other wall heater brands across LA County, South Bay, and Orange County.
AIRONE services all major heating brands across all system types including Carrier, Trane, Lennox, Rheem, Goodman, Ruud, York, Bryant, American Standard, Amana, Daikin, Mitsubishi, Fujitsu, Williams, Empire, Comfort Glow, and others. CA License #114807 covers all makes and models across Los Angeles County, South Bay, and Orange County.
As a general rule, if a heater repair costs more than 50% of the cost of a new system and the heater is over 15 years old, replacement is typically the better long-term investment. This applies to all system types - gas furnaces, wall heaters, and heat pumps. AIRONE technicians will tell you honestly which direction makes financial sense and provide written quotes for both options when the decision is close.
Heating system lifespan in Los Angeles is longer than national averages due to the mild climate and lower annual heating hours. Gas furnaces in SoCal typically last 15–25 years. Wall heaters can last 20–30 years with proper maintenance. Heat pumps typically last 12–20 years. Electric baseboard heaters can last 20+ years. A system approaching end of expected life is a candidate for replacement rather than major repair, regardless of apparent condition.
Yes - AIRONE provides 24/7 emergency heater repair dispatch across Los Angeles, South Bay, and Orange County. Emergency calls are dispatched within 2–4 hours. For gas odors, contact SoCalGas first at 1-800-427-2200 before calling any HVAC company. For CO detector alerts, leave the building and call 911 first, then call AIRONE at (323) 471-1037.

C-20 covers gas appliance repair and replacement under California Contractor State License Board requirements. All gas line work follows California Plumbing Code. CSLB license verification available at cslb.ca.gov - search license #114807.
Yes - the $89 diagnostic fee is charged for the technician's time and assessment regardless of whether you proceed with the repair. If you do proceed with the repair, the $89 is applied toward the repair cost - you do not pay it separately. AIRONE provides a written flat-rate repair quote before any work begins. You decide whether to proceed before a single repair is made.
