6 Key Furnace Maintenance Tips to Be Ready for Winter

Every furnace is going to be subject to wear and tear over time.

After all, it’s one of the things we rely on most in our homes, and as the temperature drops, we rely on it even more!

But just because your furnace is working hard for you, doesn’t mean it can’t always be working as efficiently as possible. When the furnace efficiency is what it should be, you’ll be more comfortable, the air will be cleaner in the home, you’ll be helping your system last longer‑and you’ll be saving money, too.

Knowing furnace maintenance is critical this time of year, we’re breaking down 6 simple tips to help your furnace perform efficiently and optimally this winter:

  1. Check that your thermostat is working properly
  2. Keep the air filters clean
  3. Make cleaning around the HVAC part of your routine
  4. Rely on your programmable thermostat
  5. Listen for any noises that aren’t normal
  6. Check your garage to be sure it is sealed well

1. Check that your thermostat is working properly

It’s true that old age, problems with wiring, or even issues with the transformer could be at fault for the problems you are experiencing. When it comes to troubleshooting on your own, what you can do is check that the batteries are working as they should.

All thermostats are different, and some models don’t actually require batteries. If you have trouble changing or finding out more details about your specific thermostat and its source of power/batteries it requires, let us know.

If you have reason to believe it is a mechanical or operational issue, then call us so we look further into the issue.

2. Keep the air filters clean

Air filters are a key part of proper HVAC filtration and efficiency, and that filtration and efficiency is really the foundation of indoor air quality. Put simply, your air filters are one of the most powerful parts you can control of your HVAC working as it should.

Proper filtration keeps indoor air clean and free from dust and particulates that make your system work harder and that have other harmful risks you’re your health. So while you may say the job of an air filter is to protect your HVAC from harmful particles, arguably, a byproduct of that is that they improve your overall indoor air quality.

Ask us and we can help you know the right filter change-out frequency. Here are some guidelines to help:

  • For small apartments/condos or single occupant without a pet: at least twice a year, although certain pets will change that frequency.
  • Office setting: this can really vary, but an average, every two months. If you are near construction, it may even be more often.
  • Typical home with 1 pet: at least every 90 days, or more often if we told you so.
  • Anytime you have a pet, young child, or someone with allergies, we recommend changing the air filter out every 20-60 days.

3. Make cleaning around the HVAC part of your routine

If debris or materials are getting in the way, of course it’s going to impact its ability to work as it should. Also keep in mind it is not just debris, it is also dust and dirt. You want to do anything you can to make sure the burners don’t have a layer of dust o them and you want to be sure the heat exchangers don’t have dust or materials on them either (1, 2).

4. Rely on your programmable thermostat 

The beauty of a programmable thermostat is you set it and you save and you don’t have to think twice about your comfort.

If you set your thermostat about 1 to 2 degrees lower than the normal temperature you keep it at in the winter months, you can see up to 3 percent savings (sometimes less) on your energy bill.

Say that your energy bill is normally $100. That’s going to be $3 per bill, but you may not even realize the difference and you may not even be home—or you could be sleeping and truly not feel the difference, but still see the savings.

5. Listen for any noises that aren’t normal

Squealing, rattling, clanking, squealing, clicking or “thwapping”—or really any non-typical noise coming from your system— is reason to be concerned. Don’t ignore it and give us a call because it could be a sign of a malfunction.

6. Check your garage to be sure it is sealed well

People don’t often know just how much energy is being lost in the garage. If you are able, see if your garage door is touching all the way down to the ground. You don’t want any major drafts that can get in along the bottom or sides (2).
