Here’s How to Reduce the Load on Your Furnace


Your home’s heating load indicates the amount of energy your furnace needs to use to keep you warm and comfortable. If you lower the load, you will save energy and potentially help your heating system last longer with fewer repairs. Help make your furnace’s job easier with these tips.

Regular Filter Changes

Start with an easy one first by checking your air filter. A dirty filter makes your heating system work much harder to pull airflow across the heat exchanger. Further, you’ll save energy by staying on top of filter changes.

Thermostat Settings

Frequently changing the thermostat temperature can reduce heating efficiency. Your best bet for saving energy and maintaining the comfort level you desire is by upgrading to a programmable or Wi-Fi thermostat.

Check Ductwork

In addition to increasing your energy bills, duct leaks increase the stress and load on your furnace. If you find a disconnected duct seam or locate a leak, you can make a quick repair by wrapping it with heat-resistant metal tape.

Air Sealing and Insulation

Air sealing and insulating your Portland area home is a great and practical way to lessen the load on your heating system. Additionally, sealing and insulation lasts for many years and you will save energy and be more comfortable year-round.

  • Air sealing — Use foam and silicone weatherstripping to seal your attic door and entry doors respectively. A thin line of caulk seals window frames from the outside. Caulk rope and tension strips seal your windows from the inside.
  • Insulation — If you use fiberglass insulation in your attic, it should be higher than the joists. Energy Star recommends attic insulation as high as R-60, which is about 15 to 18 inches of standard fiberglass.

Professional Maintenance

Schedule professional preventive maintenance each spring and fall seasons to keep your furnace, A/C, and ducts in great shape. Professional cleaning, system inspection, and testing ensures that your furnace is operating efficiently and safely.
