Heating calls in Los Angeles
What breaks on the heating side in Los Angeles depends on what the home runs. Gas furnaces fail at the igniter, the flame sensor and the limit switch. Heat pumps fail at the reversing valve and the defrost board. They are not interchangeable diagnoses.
These 94 ZIP codes cover Los Angeles inside Los Angeles County, and all of them route heating calls to the same line. Each links through to its own page where one exists.
Local considerations
Heating equipment replacement in Los Angeles normally needs a permit from the local building department, and venting is usually the part that gets inspected. The provider typically handles the permit as part of the job.
Heat pump performance in Los Angeles depends on outdoor temperature in a way that gas equipment does not. The capacity drop at low ambient temperatures is normal and predictable, and sizing accounts for it with auxiliary heat.

Furnace Repair in Los Angeles
Cold-snap calls arrive in clusters, which is why a furnace repair at 11 pm in January is a genuinely different urgency than a tune-up in September.

02 Furnace Installation and Replacement in Los Angeles
A cracked heat exchanger is a carbon monoxide risk, not a comfort problem, and it ends the repair conversation immediately.
Details
03 Heat Pump Repair in Los Angeles
Heating mode adds the reversing valve and the defrost cycle, and a unit stuck on auxiliary resistance heat still warms the house while the bill climbs.
Details
04 Boiler Repair in Los Angeles
Circulator pump failure stops the heated water from reaching the radiators. The boiler may fire and reach temperature while every room stays cold.
Details
05 Thermostat Installation and Repair in Los Angeles
Heat pump thermostats have additional complexity in the form of balance points and auxiliary heat staging, which means replacement requires matching the control to the equipment.
Details
06 HVAC Maintenance and Tune-Up in Los Angeles
Pre-heating-season maintenance costs a fraction of the emergency call it prevents, and it avoids the extended wait times that cold-snap season generates.

What is your thermostat reading?
Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

- Likely cause band
- Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.
- Urgency
- Call today
- Read next
- AC not cooling
What to do while you wait
- Switch the thermostat off so the system stops attempting ignition over and over.
- Confirm the gas supply valve is open and that a service switch has not been knocked off.
- Check the filter. A blocked one makes the furnace overheat and shut itself down.
- Keep interior doors open so the warmth remaining in the house distributes evenly.

Los Angeles HVAC questions
What if my furnace is still under warranty?
Parts warranties of five to ten years are common, labor warranties are not. Have the model and serial number ready when you call so the provider can check coverage before fitting anything.
My furnace locks out after three tries. What is that?
Three failed ignition attempts followed by a lockout usually means the flame sensor is dirty, the igniter is weak or gas pressure is wrong. After a long idle summer, cleaning resolves it more often than replacing parts does.
Is a cracked heat exchanger repairable?
No. A cracked heat exchanger is a carbon monoxide risk rather than a comfort fault, and the correct response is replacement of the furnace. Any provider suggesting a patch on one is giving you poor advice.
Can I run a space heater meanwhile?
Portable heaters carry their own fire risk and should never be left running unattended or near fabric. Never use a gas range or an outdoor appliance to heat a room, which is a direct carbon monoxide hazard.
Do I need a carbon monoxide alarm?
If any gas appliance runs in the home, yes. Carbon monoxide is colourless and odourless, and a working alarm near sleeping areas is the only reliable warning. If one sounds, leave the building and call 911 from outside.
