An energy audit can help detect home cooling waste, and gauge the efficiency
of your current cooling system. Your utility company may offer free or low-cost
energy audits, or you can conduct your own.
Energy Audit Ideas
Have your central air conditioning (AC) system serviced each spring. Your
utility company may provide this service.
Hire a professional to seal and insulate leaky ducts, and to ensure that
the airflow distribution system is operating at peak efficiency.
Clean or replace AC and furnace filters once a month or as needed, and seal
holes around plumbing and heating pipes.
Install a programmable thermostat. You can save money by keeping the home
warmer than normal when you are out, and by setting the thermostat at 78 degrees
when you are home.
Install drapes, shades, blinds, or another window covering. Keeping them
closed during the day blocks most sun heating rays.
Consider replacing single-pane windows with double-pane windows with high-performance
glass. Look for low-emissive (low-e) rating, or spectrally selective glass. In
warmer climates, select windows with spectrally selective coatings to reduce
heat gain. In colder climates, select windows that are gas filled with low-e
coatings on the glass to reduce heat loss.
Open your foundation vents each spring with crawl space homes.
Install ceiling fans. The air circulation promotes cooling in the summer
and heating efficiency in the winter.
Prune back shrubs and remove grass or debris that may block airflow to your
Plant a tree. Landscaping is a natural way to shade your home. Well-placed
trees and shrubs not only deliver shade, but also add value to your property.
Shade room air conditioners from direct sun exposure to reduce their workload.
