The Benefits of Annual Furnace Maintenance

It’s always most important to actually know what you’re getting out of a service. So what does professional maintenance have to offer you and your home? Quite a bit! Benefits of routine service include:

  • A more comfortable home. The calibrations, cleaning, and optimizations that are administered during a professional service all go toward making your system much better at its job. Maintenance restores your system to perfect heating power, equipping you to take on even the worst of winter’s days and nights.
  • Higher energy efficiency. A well-maintained furnace will do a better job overall, for sure, but it will also need less fuel to do it! Whether you rely on a gas furnace or an electric furnace, the system’s efficiency governs how much you pay to get your comfort. And with our maintenance, you’re guaranteed to be paying in less.
  • Lower breakdown risks. A tune-up service gives our professionals an opportunity to check for malfunctioning parts, loose electrical connections, and other common problems. That means you get to avoid these completely, ensuring your system can heat your home with no interruptions.
  • Less-costly repairs. If you do happen to need repairs mid-season, it’s far less likely to be a high-cost service because your major components are protected by a thorough professional maintenance service.
  • Better indoor air quality. Clearing out accumulated dust and grime goes a long way in boosting your system’s effectiveness, but you’ll benefit from it, too! Less muck in the ducts and machine means less muck in your home air, and less of it getting into your lungs!

9 Signs You Need Furnace Maintenance

Regular furnace maintenance will save you money and time in the long run. It’s a good idea to schedule furnace maintenance services at least twice a year, but how do you know when your furnace needs immediate attention? Here are the top nine signs that your furnace needs to be looked at right away:

1. Your furnace is making strange noises

If you hear banging or groaning noises coming from your furnace, chances are it’s time to schedule a furnace maintenance appointment. There could be a loose belt, a problem with the ignition, or another issue.

2. Your furnace is more than 10 years old

The average life span of a furnace is anywhere between 10 and 20 years. If your furnace is more than 10 years old, you should schedule a furnace inspection soon.

3. Your furnace smells bad

If you notice a strange smell coming from your furnace, it is probably a sign that it needs maintenance. Whether the filter is just dirty or an electrical component needs to be repaired, it is important to schedule an appointment with an HVAC professional to get it taken care of.

4. The pilot light is yellow or orange, instead of blue

When oxygen levels are restricted, the pilot light on your furnace can turn yellow or orange instead of blue. The air intake valve could be clogged with dirt, so it’s probably time to schedule a furnace maintenance appointment.

5. Your utility bills are much higher than usual

If your energy bills are increasing, your furnace may not be running properly. Furnace maintenance will ensure your system is running as efficiently as possible so you won’t keep overpaying on utility bills.

6. Your furnace isn’t keeping you comfortable

When your furnace is functioning properly, it should keep your house at comfortable temperatures throughout the year. If you turn up your thermostat and your home stays chilly, you need furnace maintenance right away.

7. Your furnace keeps turning off and on

If you notice your furnace turning on, running for a few seconds, and then turning off again, it’s a good idea to schedule a furnace inspection in case it needs to be repaired.

8. You’ve gotten multiple furnace repairs in the past two years

If you’ve needed furnace repairs more than once in the past two years, there’s a good chance your furnace is not in the best condition. Regular furnace maintenance will help detect any issues so you can get them repaired before any more damage is done.

9. Your carbon monoxide detector goes off

If the carbon monoxide detector goes off, your furnace may not be burning fuel completely. Shut off all your gas appliances―including your furnace―open the window, and call the fire department immediately. When your home has been cleared for re-entry, call an HVAC contractor for furnace maintenance.

How Important Is a Furnace Tune-Up?

Scheduling an annual furnace tune-up is absolutely imperative if you want the system to operate at its peak efficiency, and if you want to avoid mid-season breakdowns. A tune-up includes vital services like in-depth cleaning, component inspections, performance evaluation, and more—all of which go a long way in reducing potential complications and improving performance.

Going into a tune-up, expect the service to last around two hours, and for the cost to be based on service plus needed parts.

When Should I Schedule a Furnace Maintenance Service?

If you notice your furnace is not working properly, do not hesitate to call GAC Services. We’ll send a technician to inspect and tune up your furnace right away. Your entire heating system will benefit from scheduling an annual furnace tune-up in the fall or beginning of winter, just before the peak of heating season.
