Making energy-efficient upgrades to your home is a great way to add value, but you should figure out what changes are actually necessary before you make any significant improvements. A home energy audit can give you an idea of what improvements can give you the biggest bang for your buck.
Follow these steps to conduct your own energy audit:
- Check for air leaks. Inspect your home for air leaks, which can waste up to 10 percent of your home’s energy. Seal any obvious leaks, such as those around windows or baseboards, with caulk or weather stripping to ensure your hot and cold air isn’t just blowing outside.
- Perform a pressurization test. Not every leak will be easy to find. For the smaller energy-wasters you’ll need to conduct a pressurization test.
- Examine your insulation. Since heating and cooling your home represents more than half of your energy expenses, adding insulation can provide a nice return on investment. Check to see whether you have adequate insulation by using a thermographic leak detector. The detector uses colors to show hot or cold spots in your home. Any irregularities could mean there’s not enough insulation.
- Inspect your ductwork. Make sure your heating and cooling is moving through your system as efficiently as possible. Inspect your ductwork for dirt streaks, which can be a sign of air leaks. Seal obvious problem areas with duct mastic or invest in a professional to examine the ducts more thoroughly.
- Think about replacing your appliances. Calculate the energy consumption of your appliances and compare them with newer models. You may be able to save on energy costs by upgrading.
