How to Help Your Furnace Work Better in Your Home

Although your furnace might appear to be working, the question is, how well?

It’s not uncommon for a furnace to be in good condition, but still not reach optimum performance. In fact, issues such as poor insulation or old doors and windows can keep even a brand-new furnace from working efficiently. If you would like to keep your furnace working better, here are some easy tips to keep your home toasty warm this winter.

How Long Should a Furnace Last?

First, it helps to know the age of your furnace. According to the experts at This Old House, a furnace should last about 15 to 20 years. If your furnace is over 15-years-old, it’s reaching the end of its expected life span.

Although a well-maintained furnace could last beyond its years, you should pay attention to the factors that will age your furnace, as well as signs it has seen better days.

Signs Your Furnace is Aging

An obvious sign your furnace is aging is frequent breakdowns. If you find you’re calling in a repair team every fall, ask them if it makes more sense to replace your furnace instead of investing in constant repairs.

Some less obvious signs your furnace is aging include:

  1. Rising energy bills as your furnace becomes less efficient at heating your home.
  2. Uneven heating where you find some rooms or areas of your home tends to be colder than others.
  3. Frequent cycling where you can hear your furnace turning on and off often as it tries to maintain the set temperature.
  4. Issues with air quality such as noticeable humidity or more dust in your home.

If you are noticing any of these signs, you can speak to our heating experts. We can assess your furnace to determine if it is time for a new heating system.

Tips to Improve Your Furnace’s Efficiency

Although your goal is to help your furnace work better, a lot of the steps you should take don’t directly involve the furnace itself. Instead, you want to ensure your home is properly insulated to reduce wasted energy.

To improve your home’s heating efficiency, you can try the following:

Improve insulation: Your home has insulation in the walls, ceiling, and attic to prevent heat (and cool air) from escaping. Making sure your attic is properly insulated can help keep heat inside your home.

Caulk door and window frames: Check your door and window frames and make sure there aren’t any cracks. You can also hold up your hand to see if you feel cool air or air movement around windows and doors.

Add new weather-stripping: You can use weather-stripping as an added seal where doors and windows have moving parts. This provides a tighter seal when your doors and windows are closed.

Change furnace filters: Your furnace filters should be changed at least every one to three months. You can put a reminder in your phone, so you don’t forget!

Annual maintenance: Annual maintenance will help keep your furnace operating efficiently. Every fall you should call your local heating and cooling experts to arrange a furnace tune-up.

These tips will help your furnace work better in your home. If you’d like more information about heating efficiency for your home, speak to our team.



Is Your Furnace Making a Loud Buzzing Noise? Here’s What You Can Do About It.

Is your furnace making a loud buzzing sound? Or a crackling or humming sound? There are a few common noises that may be coming from your furnace. Read on for these and more issues, what they mean and how you can remedy them.

Is Your Furnace Making a Loud Buzzing Noise?

  • Your furnace has a transformer box. If it is dying or not secured properly, it can buzz. You can fix a poorly mounted box with a screw driver. However, if the transformer itself needs to be replaced, you must call in a professional.
  • The capacitor might also be broken which could cause the motor to buzz. The capacitor is a silver device that stores electricity and helps the motor start. Call in a professional to replace the capacitor, which is quite easy and inexpensive to replace.
  • If the blower motor has blown, it will often buzz or hum when the power to the furnace is turned on. Replacing a motor is complicated and requires you to disconnect the old wires and remove the motor shaft from the blower housing. This is a job for a professional HVAC specialist.

Other Common Furnace Noises

Crackling Noise:

If your furnace is making a crackling noise, it could be operating normally. Just after your furnace turns off you may hear a crackling sound coming from it. This sound could be the ducts cooling after operation. Pay attention to when the sound occurs. If it’s persistent, or occurs when the furnace is in use, it might be a sign of a bigger problem.

Knocking Noise:

Your furnace making a knocking noise or a loud pop or bang when starting up could mean problems with the expanding and contracting of your air ducts. They may have issues that need to be repaired such as undersized ducts, flimsy ducts, closed vents or a clogged air filter.

If dirt builds in your furnace burners it can delay ignition and cause gas to build up. When it does ignite you will hear a loud pop or bang. If not checked out, this process could crack or damage your heat exchanger, which can be expensive to repair.

Humming Noise:

Your furnace making a humming noise could simply be the blower motor. This sound could be a result of improper lubrication. Turn off your motor and check it when it is cooled enough to touch.

Clicking Noise:

If your furnace is making a clicking noise while running it will need immediate attention. This sound could be an indication of a faulty flame sensor, or a problem between the ignition and the gas.

These are just some of the problematic noises that your furnace can make. If you hear any noises that concern you, please don’t hesitate to get your furnace checked out by a professional at D&B ClimateCare.
