Which one of these will NOT increase the efficiency of your air conditioner?
Adding attic insulation
Using LED lights (instead of incandescent or halogen bulbs)
Adding a HEPA filter to your HVAC
Getting a yearly tune-up of your system
If you answered “C” Adding a HEPA filter, you’re right! HEPA filters are not recommended for HVAC units, as they restrict air flow and make your air-conditioner work harder, causing it to fail earlier. Adding attic insulation is one of the best things you can do to increase your heating and air-conditioning efficiency, and reduce energy costs. Swapping out your incandescent and halogen lights for LED lights will prevent your air-conditioner from having to overcome the heat these lights emit, so it’s a great efficiency-booster as well! And, getting a yearly tune-up is essential for keeping your air-conditioner running at peak performance and maintaining its efficiency.
