3 Tips to Make Your HVAC More Energy Efficient In the Winter Months

The cold months of winter arrive this week. After the deep freeze we experienced last week, it looks like Middle Tennessee may be in for a challenging winter in 2017. During these long, cold winter months your furnace will work much harder and will require more energy than any other time of year. Fortunately, there are some steps you can take now to make your HVAC more energy efficient and save you money during the winter months!

1. Change the filter.

This is one of the easiest ways to make your furnace more energy efficient. If your filters are dirty the furnace will have to work harder to heat the home. Here's a helpful resource we put together for choosing the right air filter for your home. We recommend filters with MERV ratings between 8 and 11. They seem to be the most cost-effective.


2. Locate and take care of drafty areas in your home.

A good exercise is to get near a drafty area, close your eyes and imagine dollar bills leaving your home along with the heat. In our previous blog post, 4 THINGS YOU CAN DO NOW TO PREPARE FOR WINTER we took you through some of the most drafty areas of your home and provided some tips on sealing them to prepare your home for winter. Managing your drafts can result in energy savings during the winter months

3. Lower your thermostat while sleeping or away from home.

If you do not yet have a smart thermostat you will need to do this manually. There's really no need for your HVAC unit to work hard when everyone is sleeping or no one is home. The Department of Energy says You can save as much as 10% a year on heating and cooling by turning your thermostat back 7°-10°F for 8 hours a day- a normal workday!

There are further steps you can take to continue to reduce energy costs in your home but just starting with these 3 will get you off to a good start!
