Energy Savings Tips: Home Heating

Change your air filter. Check your filter monthly during summer and winter when the system is used the most. If the filter looks dirty, change it. At minimum, you should change the filter every 3 months. A system with a dirty filter has to work harder to keep you warm or cool. A clean filter will also prevent dust and dirt from building up in the system, which can reduce maintenance costs.

Install a programmable thermostat A programmable thermostat can save you 10% or more on your heating and cooling costs. Adjust the program to keep your home 8 to 10 degrees cooler (in winter), or 8 to 10 degrees warmer (in summer) while you are asleep or at work.

Seal your heating and cooling ducts. Leaky air ducts can waste as much as 25% of the warm or cool air produced by your HVAC system. Sealing and insulating ducts can improve efficiency and make your house more comfortable.

Focus on sealing ducts that run through the attic, crawlspace, unheated basement, or garage. Use duct sealant (mastic) or metal-backed (foil) tape to seal the seams and connections of ducts. (Do not use cloth-backed Duct Tape.) After sealing the ducts in those spaces, wrap them in insulation to keep them from getting hot in the summer or cold in the winter.

Find and seal air leaks This is one of the most cost-effective things you can do to reduce your energy bills. It will also make your home more comfortable by eliminating drafts. Use caulk or weather-stripping to seal the air leaks around windows, doors, wall penetrations for pipes and wires, dryer vents, air conditioners, etc. For step-by-step instructions, see DIY Guide to Sealing and Insulating with ENERGY STAR.

Add insulation to the attic If the insulation in your attic is just level with or below your floor joists (i.e., you can easily see your joists), you should add more. It is important that the insulation be evenly distributed with no low spots; sometimes there is enough insulation in the middle of the attic and very little along the eaves. The amount you save will depend on many factors, like the condition of the existing insulation and the efficiency of your heating system. Download Energy Star’s DIY Guide for more details.

Use ceiling fans to save on heating costs In winter, run the fan in reverse at the lowest speed to force warm air near the ceiling down into the occupied space. Bringing the warm air down from the ceiling will enable to feel comfortable a lower thermostat setting. For each degree you lower your thermostat, you'll reduce heating costs 3 percent to 5 percent.

Upgrade to more efficient furnace or boiler If your furnace or boiler is more than 15 years old, consider replacing it with Energy Star qualified equipment. Energy Star rated furnaces are at least 15% more efficient than conventional models. Here’s what to look for:

  • Gas furnaces: Look for models with an Annualized Fuel Utilization Efficiency (AFUE) rating of at least 95%.
  • Oil Furnaces: Look for models with an AFUE of of 90% or higher.
  • Hot Water Boilers: Look for models with an AFUE of of 90% or higher.
