Concerned the cold, desert-like nights are increasing your energy bills? Check out these tips from the heating experts at Johnson Air to find out how you can keep your energy bill low and your home comfort level high.

Tip #1: Check Your Heating System’s AFUE Rating

The Annual Fuel Utilization Efficiency (AFUE) tells you what percentage of fuel consumed by your furnace, water heater or boiler is used to heat your home and what percentage is being wasted. The higher the AFUE number, the greater the efficiency. For example, a 90% rating means that 90% of the heat a furnace creates is used directly by the home while 10% is lost (1). Fuel is typically ‘lost’ or wasted through ventilation. To make sure you are not overpaying for the fuel used by your heating system, call a licensed HVAC contractor who can perform an inspection of your heating and ventilation.

Tip #2: Lower Your Thermostat Setting

While this may seem obvious, it is a surefire way to lower your energy bills during the months you need your heating system the most. According to the American Council for an Energy-Efficient Economy (ACEEE) you can save about 3% on your gas bill for every degree you decrease the temperatures on your thermostat. Furthermore, if you turn it down 10 degrees when you leave the house and at night (approximately 16 hours a day), you can save up to 14% (2).

Tip #3: Lower Your Water Temperature Setting

Thermostats have preset internal temperatures when you purchase them and water heaters are no exception. Manufacturers typically preset water heaters to 140 degrees Fahrenheit, however most homeowners won’t require more than 120 degrees for their water to stay an ideal temperature. According to the U.S. Department of Energy, you can lower your energy costs by 3-5% by decreasing your water temperature by 10 degrees (3).

Tip #4: Perform Regular Maintenance

The best thing you can do for your heating system is to have a reliable, NATE-certified technician perform regular service on it. Unmaintained gas furnaces, especially older models, not only increase energy costs but can be serious safety concern. The rule of thumb for HVAC maintenance is twice a year to keep it running at optimal performance. However, there are several DIY maintenance tasks that can be performed in-house. For example, changing out your air filter regularly will help reduce strain on your system, ultimately reducing the amount of energy consumed by your furnace.    

Tip #5: Replace Your Outdated Heating System

Understanding when you need to replace an outdated furnace can be the difference between a healthy, energy-efficient home, or expensive utilities and poor indoor air quality. Furnaces generally have the same life expectancy around 15-20 years, whereas heat pumps work year-round and have a slightly shorter life, typically 10-15 years. Today’s high-efficiency heating systems are 60 percent more efficient than technologies from just a decade ago (4) and you can see a return on your HVAC investment in as little as 2 years through drastically lower energy costs.

Other useful tips to lower heating costs:

  • Use the fireplace instead of the furnace if you have one
  • Uncover all vents and remove any obstacles around them
  • Insulate your doors and windows
