How Often Should You Service Your Heating System?

Is your home as warm as it should be? Or maybe your business feels drafty, even with the thermostat turned up? If you’ve ever wondered how often you should service your heating system, you’re not alone. At GOGO Heating, we hear this question from homeowners and building managers all the time.

Skipping regular heating maintenance is a bit like ignoring the oil change light in your car. It runs—until it doesn’t. Then, the fix is usually far more costly and inconvenient. Let’s break down exactly how to keep your heating system humming year after year.

Recommended Heating Service Frequency 🛠️

No matter what type of heating system you have—furnace, geothermal, radiant, or heat pump—routine care is essential. Here’s the short answer most experts agree on:

• Once a year. That’s the golden rule for most residential and commercial heating systems.
• Schedule your service in the fall, before the first real cold snap. This gives you time to fix any issues before you need steady heat.

The U.S. Department of Energy and the Air Conditioning Contractors of America recommend annual maintenance for both safety and efficiency. If your system is used heavily (such as in a commercial setting), consider scheduling service every six months.

Signs It’s Time for Immediate Service

• Unusual noises (banging, rattling, hissing)
• Uneven heating across rooms
• Higher-than-normal energy bills
• Strange smells (burning, musty, or “hot” odors)
• The system won’t start, or cycles on and off rapidly

If you notice any of these warning signs, don’t wait for your next routine appointment.

What Happens During Service

Think of heating system service as a wellness check-up. A qualified technician will:

• Inspect and clean burners, heat exchangers, and ignition systems
• Check and replace air filters
• Test safety controls, thermostat calibration, and system startup/shutdown
• Lubricate moving parts like fans and motors
• Inspect ductwork for leaks and blockages
• Verify carbon monoxide (CO) and combustion safety (see guidelines by the National Fire Protection Association)
• Assess indoor air quality, especially if you have allergies, pets, or recent construction

For commercial properties or more complex systems, tasks may include air balancing, hood & exhaust inspection, and IAQ (indoor air quality) testing.

Why Filters Matter

Clogged filters force your system to work harder, lowering efficiency and increasing wear. Changing filters every 1–3 months (or as recommended by the manufacturer) is one of the simplest ways to extend your system’s life. See our Filters service page for more details.

DIY vs. Professional Maintenance

You can—and should—do a few things yourself:

• Change or clean filters regularly.
• Keep outdoor units free of leaves, debris, and snow.
• Set thermostat schedules for efficiency.

But for everything else, call a trained technician. Why? Because modern heating systems are more complex than ever. Opening up a furnace or heat pump without proper knowledge can be risky. There’s also the invisible danger of carbon monoxide leaks—a serious health risk that must be checked with professional-grade tools.

Professional Service Advantages

• Thorough safety inspections
• Correct calibration and testing
• Early detection of worn or failing parts
• Code-compliant repairs and documentation

Benefits of Regular Service 🌡️

Why bother with annual heating system service? Here’s what you gain:

• Lower energy bills. Well-maintained heaters run more efficiently, using less power for the same comfort.
• Fewer breakdowns. Routine checks catch small problems before they snowball into expensive repairs.
• Longer system lifespan. Clean, tuned-up equipment simply lasts longer.
• Healthier indoor air. Filter changes and duct cleaning remove dust, allergens, and even mold spores.
• Peace of mind. Annual safety checks help prevent gas leaks or dangerous carbon monoxide exposure.

Industry sources like ENERGY STAR and the EPA recommend regular service for these reasons.

How to Remember Service Dates 🔔

Life gets busy. Here are a few tricks to make sure heating maintenance doesn’t slip through the cracks:

• Set a recurring calendar reminder every fall.
• Sign up for a maintenance plan (ask about options when you call).
• Change your filters with every new season—a natural cue before the cold hits.
• Pair service with another annual event (like daylight saving time).

Frequently Asked Questions

How long does a typical heating maintenance visit take?

Most visits last between 60–90 minutes for a standard residential system. Larger or more complex systems (like in commercial spaces) may take longer.

Can I skip a year if everything seems fine?

You can, but it’s risky. Many problems are invisible—like a cracked heat exchanger or a slow refrigerant leak. Annual service is like insurance for your comfort and safety.

Is heating maintenance required by law?

In most cases, it’s not legally required for homeowners. However, landlords and commercial property managers are often subject to local codes (check with your city or county building department).

Will regular maintenance affect my warranty?

Yes—most manufacturers require proof of annual service to keep your warranty valid. Save those receipts!

Local and Seasonal Considerations 🗓️

In North Carolina and similar climates, fall is the ideal time for heating maintenance. Winters can be unpredictable—one year it’s mild, the next it’s icy. Early service means you won’t be caught off guard when temperatures drop.

If you run a business, consider scheduling separate visits for peak and off-peak seasons, especially if your heating system supports sensitive environments (like food service or healthcare).
