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.
Get Same-Day Heater Repair →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.
Get Same-Day Heater Repair →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.
Get Same-Day Heater Repair →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.
Get Same-Day Heater Repair →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.
Get Same-Day Heater Repair →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.
Get Same-Day Heater Repair →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.
Get Same-Day Heater Repair →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.
Get Same-Day Heater Repair →Recognizing any of these? Call (323) 471-1037 for same-day heater diagnosis - $89 flat-rate diagnostic, applied toward the repair.
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.
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 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.
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 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 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 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.
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 →
Five steps from your first call to a heated home. Live dispatcher. No surprise charges. No subcontractors.
A live AIRONE dispatcher answers - no voicemail, no call center. You describe the symptom and your system type (if known). We confirm same-day availability in your area and give you an arrival window. If you don't know your system type, that is fine - the technician identifies it on arrival.
The technician arrives with diagnostic tools, identifies your system type, inspects the root cause of the failure, and provides a written flat-rate repair quote before any work begins. The $89 diagnostic fee is applied toward the repair cost if you proceed.
You receive the repair price in writing before a single part is touched. Approval required. The price on the quote is the price on the invoice. No estimates that change mid-job.
Approximately 80% of common heater repairs are completed on the first visit. Parts for the most common failures are carried on every AIRONE service truck. Complex repairs or parts requiring special ordering are scheduled within 24–48 hours with a temporary solution provided where possible.
The system is tested before the technician leaves - heat output confirmed, safety systems verified, gas combustion checked where applicable. A written service report is provided on every job.
AIRONE services all heating system types across 126 cities in Southern California.
AIRONE services all heating system types across all of LA County. The San Fernando Valley - Burbank, Glendale, Pasadena, Arcadia, Alhambra - has the highest heating repair demand in the service area due to colder inland winters and a large stock of older homes with aging gas furnaces and wall heaters. Highland Park, Eagle Rock, and Silver Lake have a high concentration of older floor furnaces and wall heaters in pre-1960s housing stock. AIRONE services all of these system types.
South Bay heater repair with same flat-rate pricing. South Bay winters are mild but overnight lows in the 40s make heating systems essential from November through March. Coastal properties near Manhattan Beach, Redondo Beach, and Hermosa Beach have a high concentration of older wall heaters and electric heating in smaller units and condos. Salt air accelerates corrosion on all gas components.
OC heater repair with same permit compliance and flat-rate pricing. Inland OC cities - Anaheim, Yorba Linda, Orange - experience colder winters than coastal OC and have higher heating system usage. Many OC apartments and older homes use wall heaters rather than central forced-air systems. AIRONE services all heating types across all 32 OC cities in the service area.
