Furnace tune-up and maintenance services in Los Angeles

Mike Diamond’s furnace technicians provide tune-ups and maintenance for gas and electric heating systems in Los Angeles. Our technicians inspect the furnace, check airflow and controls, clean components that collect dust and buildup, and test how the system starts, heats, and shuts off.

Furnace inspection and tune-up

Our furnace technicians inspect, clean, test, and adjust the components that affect heating performance.

Filter and airflow check

Our technicians check the installed filter and look for airflow restrictions that can reduce comfort or make the furnace work harder.

Thermostat and operating cycle test

Our technicians test thermostat response and confirm that the furnace starts, heats, and shuts off normally.

Gas furnace safety checks

Our technicians check the ignition system, burners, venting, and safety controls on gas furnaces.

A furnace that does not heat, repeatedly shuts off, or has another active problem needs furnace repair rather than routine maintenance.

How can a furnace tune-up help?

Help the furnace heat your home reliably

Regular furnace maintenance removes dust and buildup, checks airflow, and confirms that the controls and heating cycle respond normally. These steps help the system run more consistently and give the technician a clear picture of its current condition.

Catch developing problems

Our technician may find a worn part, loose connection, airflow restriction, or other problem that needs repair. You receive a clear explanation of the issue and the recommended next step, so you can address it before it causes a larger interruption.

When should you schedule furnace maintenance?

About once a year

ENERGY STAR recommends an annual heating-system check. A yearly tune-up gives the filter, airflow, controls, and heating components regular attention.

When you do not know the last service date

Our technician can inspect the furnace’s current condition and identify the maintenance it needs. When you request furnace maintenance, share the system type, approximate age, filter information, and any recent change in comfort or operation.

What happens during a furnace tune-up?

Our technician completes the following steps as part of your furnace tune-up:

1. Review how the furnace has been running
We ask about filter changes, comfort concerns, maintenance history, and any recent change in furnace operation.
2. Inspect the furnace
The inspection covers the furnace, airflow, electrical connections, controls, and heating components that apply to the system.
3. Clean, test, and adjust the system
We remove dust and buildup, test the controls and operating cycle, and make adjustments that help the furnace run correctly.
4. Explain the results
You receive a review of the completed maintenance, filter needs, and any repair that deserves attention.

When does your furnace need repair instead of a tune-up?

The furnace does not heat or keeps shutting off

A furnace that produces no heat, repeatedly shuts off, fails to ignite, or cannot reach the thermostat setting needs diagnosis. Our technician tests the controls, airflow, electrical components, ignition system, and other equipment to find the cause. Schedule furnace repair for these symptoms.

You notice a new noise, burning odor, or possible gas smell

A new mechanical noise or persistent burning odor can signal a problem that needs repair. If you smell natural gas or suspect a gas leak, leave the area immediately and call SoCalGas from a safe location. Do not operate switches or attempt a repair. After the area is safe, Mike Diamond can inspect the furnace and explain the heating repair it needs.

Furnace tune-up and maintenance questions

How often should I schedule a furnace tune-up?

ENERGY STAR recommends an annual heating-system check. Schedule service sooner if the furnace begins operating differently, comfort declines, or the maintenance history is unknown.

What is included in furnace maintenance?

Furnace maintenance typically includes checking thermostat response, the operating cycle, electrical connections, moving components, the filter, airflow, and the heating components that apply to the system. Gas-furnace maintenance can also include ignition, burner, venting, and safety-control checks; an active failure or damaged part requires repair rather than routine maintenance.

How often should I check the furnace filter?

ENERGY STAR advises homeowners to inspect the filter monthly and clean or replace it when dirty. Check it more often during heavy use or when dust and pet hair collect quickly, and follow the furnace and filter manufacturers' instructions.

How much does furnace maintenance cost in Los Angeles?

Furnace maintenance pricing depends on the furnace type, condition, access, and maintenance history. Ask whether the quoted tune-up price excludes repairs or replacement parts discovered during the inspection.

Can a furnace tune-up fix a system that is not heating?

A furnace that is not heating needs repair diagnosis because the cause may involve the thermostat, controls, airflow, electrical components, ignition system, fuel delivery, or a failed part. Describe the no-heat condition when scheduling so the appointment is treated as a repair request rather than routine maintenance.

What should I do if I smell gas near the furnace?

SoCalGas instructs people who smell natural gas or suspect a leak to leave the area immediately and call 1-800-427-2200 from a safe location. Do not operate anything that may create a spark, call 911 when there is an immediate threat, and arrange an inspection only after the area is declared safe.
