Your heating and air conditioning system is by far the largest energy consumer in your home. Except for a brief bout of snow and ice, we have experienced a pleasant, mild weather thus far. However, a cold front this weekend will usher in cooler temperatures and could signify a shift in the weather pattern.

Homeowners can significantly impact their energy usage for the remainder of winter by making a few small changes. In our next two articles, we will discuss Ten Tips for Improving Your HVAC’s energy efficiency.

1) Regularly Change Your Air Filters

It may seem like we write this in every article, but there is not a more important maintenance procedure than changing your air filters. The efficiency and effectiveness of your HVAC system depends on maximizing airflow.

When your filters are clogged with debris, airflow is reduced, and your unit will require more energy to push air through your ducts. For greater energy efficiency, homeowners should check them at least monthly, and replace them at least every two months.

2) New Doors and Windows

Drafty windows and doors can release as much as 25% of your home’s heat. Signs your windows and doors need to be replaced include:

  • Cracked or broken window panes
  • Moisture and condensation inside windows and on window sills
  • Worn weather seals around windows and doors
  • Draftiness
  • Higher energy bills

Replacing windows and doors with energy efficient options can significantly reduce your energy costs. Additionally, some window and door upgrades are available for tax credits and deductions.

3) Open Supply and Return Vents

One widely believed HVAC myth is that closing off rooms and vents improves energy efficiency. Open and unblocked air vents are important for airflow and energy efficiency. Make sure supply and return vents are not blocked by furniture or other debris.

4) Spray Foam Insulation in Attic and Crawlspace

Heat energy escaping from your home drastically affects your energy usage and costs. Having spray foam insulation added to your attic and crawlspace reduces heat loss significantly. Over the life of your home, it is possible to recoup the installation costs.

5) Keep Outdoor Unit Clear of Debris and Obstruction

Fall and winter wind and storms can cause leaves and debris to collect on or around your HVAC unit. Debris reduces airflow, so it is important to keep your system free of obstructions. Additionally, make sure you maintain at least two feet of clearance between your unit and any beautifying shrubbery and fencing.
