Resolve to be more energy efficient: April tips

energy efficiency resolutions for 2021

New Year’s diet resolutions, exercise resolutions, we’ve heard them all. But what about New Year’s energy efficiency resolutions?

For each month of 2021, OPPD Energy Advisor Eric BenSalah will offer a brief set of tips and video to help you get on track with your energy efficiency, and save you money.


Resolution: Spring cleaning – clean out your home’s air return registers. These registers, usually those without an open/close lever without air moving through them, often collect dust, pet hair and other things in the air of a home.

There are a few ways to clean them:

  • Use the brush attachment of your vacuum and move it against the grate of the register to remove any lingering dust on the surface or just inside the register.
  • Remove the register from the wall (it is usually attached by two screws) and clean it, again, using the brush attachment of your vacuum. Even give the area around the opening a good cleaning, too.

Other tips to reduce buildup:

  • If you have pets, it is recommended that you clean out the registers every two months, otherwise a few times a year can also do the trick.
  • Keeping the return registers clean helps maintain good air flow within your home and helps prolong the life of your furnace filter.

Resolution: Choose the best furnace filter for your home. Not all furnaces are created equally. The primary job of a furnace filter is to protect the internal components of your HVAC system. But its ability to help clean the air in your home can become just as important to your health and safety.

Here are some facts about furnace filters:

  • Furnace filters, like many other things, have ratings that tell you a filter’s ability to capture and hold particles and pollutants. Most furnace filters have a MERV rating (3M has MPR and The Home Depot has FPR, but have equivalents to the MERV rating).
  • The higher the MERV Rating, the smaller the particles that can be trapped when the system is running.
  • The ratings you will see:
    • MERV 6, 8, 11 and 13
    • MPR 300, 600, 1000-12000, 1500-1900
    • FPR N/A (to MERV 6), 5, 7, 10 respectively
  • The recommended MERV rating for most homes is between 8 and 11. In some cases, a high MERV Rating can affect your HVAC system’s ability to move air throughout the home making it work harder than necessary, costing you extra money and wear on your system.


Resolution: Use LED lightbulbs as much as possible. It’s an up-front investment with long-term savings. We have all heard “replace your lights with LED”, but how much can you save by switching? Below, we compare LEDs with CFLs and incandescent bulbs.

  • Light on for 10 hours per day (cost is per bulb)
    • 60w Incandescent: $1.72/month
    • 15w CFL equivalent: 0.43¢/month
    • 6w LED equivalent: 0.17¢/month
  • Cost per bulb – Life
    • Incandescent: $1.00 – 12-18 months
    • CFL: $2-3.00/bulb – 4-7 years
    • LED: $4-6/bulb – 10-15 years

The payback period for an LED is about 3 months. Meaning, you will pay off the cost of the LED from the savings (vs. an incandescent bulb) in 3 months. In turn, it could cost you more than 10 incandescent bulbs during the life of one LED light, on average, not including the increased cost of an incandescent bulb.


Resolution: Use your thermostat to your advantage

  • Working from home? Turn the thermostat down and use a space heater to supplement heating, if needed. Adding an extra layer of clothing always helps, too!
  • When leaving your home in winter, consider lowering your thermostat by four to five degrees to reduce your energy costs while you’re away. In summer, raising your thermostat by four to five degrees can have the same effect.
  • If you have a programmable thermostat, it can do the work for you. Programming the thermostat to automatically run or stop when you wake up, sleep, leave the house can help you save on energy costs.
