Questions San Diego homeowners ask

From our article What Is Included in a Furnace Tune-Up?.

What does a furnace tune-up involve?

A furnace tune-up involves a thorough inspection, cleaning, and testing of your heating system. This includes checking and calibrating the thermostat, inspecting the heat exchanger for cracks, testing electrical components, lubricating moving parts, replacing or cleaning the air filter, checking for gas or carbon monoxide leaks, and ensuring safe and efficient operation. It’s designed to prevent breakdowns, improve energy efficiency, and extend the lifespan of your furnace.

Is a furnace tune-up worth it?

Yes, a furnace tune-up is absolutely worth it. It helps catch minor issues before they turn into costly repairs, improves energy efficiency, ensures safe operation (especially by checking for carbon monoxide), and prolongs the life of your HVAC system. Routine maintenance can also maintain warranty coverage for newer systems.

How often should I get my furnace tune-up?

You should schedule a furnace tune-up at least once a year, ideally in the early fall before the heating season starts. Annual maintenance helps keep your system in peak condition and ensures you’re not left without heat during the colder months.

How long does it take to tune a furnace?

A professional furnace tune-up usually takes between 60 to 90 minutes. However, the time may vary depending on the type of system you have, its age, and whether any minor repairs or part replacements are needed during the service.
