Furnace Repair Across Los Angeles

Los Angeles winters are mild by most standards, but that doesn't mean furnaces get a free pass. Many homes here run older equipment that was installed decades ago and only gets heavy use for a few months a year, which is exactly the kind of system that tends to fail right when it's needed most. Ignition problems, worn blower motors, and thermostat miscommunication are some of the most common culprits.

Purified Air repairs furnaces of every make and age throughout Los Angeles. Our technicians diagnose the actual cause of the problem rather than guessing, and we carry common parts on our trucks so most repairs are completed in a single visit.

Signs Your Furnace Needs Repair

Furnace trouble usually shows warning signs before a full failure. Call us if you notice:

  • Furnace Won't Ignite: Often a pilot light, ignitor, or gas valve issue.
  • Blows Cold or Lukewarm Air: The blower may be running while the burner isn't firing correctly.
  • Frequent Cycling: A furnace that turns on and off repeatedly is working harder than it should.
  • Unusual Smells: A burning odor when the furnace starts up can indicate dust buildup or an electrical issue that needs attention.
  • Rising Gas Bills: An inefficient furnace uses more fuel to produce the same amount of heat.

Common Furnace Problems We See

Certain issues come up more often than others, especially in furnaces that only run seasonally.

  • Ignition System Failures: Pilot lights and electronic ignitors can fail after sitting unused through the summer.
  • Worn Blower Motors: Motors that have been running for years can develop bearing issues or stop working entirely.
  • Thermostat Miscommunication: A faulty thermostat can prevent the furnace from cycling correctly.
  • Clogged Filters: Restricted airflow forces the system to work harder and can trigger safety shutoffs.
