1 - Perform regularly scheduled maintenance on your air conditioning unit.
Replace the filter monthly during the season and have a professional service
your system at the beginning of each new season.
Install a programmable thermostat so you can change the temperature according to
when you're home and at work. Set it to 78 degrees when you're home and set
it the air conditioning at 85 degrees while you're gone..
3 - Plant shady trees and shrubs around your house to help reduce its exposure
to the sun, especially on the west and south sides. This can reduce your AC
costs by up to 30%.
4 - Close drapes & blinds on the sunny side of your house.
5 - Sealing up air leaks in your house will help reduce your air conditioning
costs. Caulk or seal places where utilities come into your home (electricity,
plumbing, dryer vents, etc.). Fill gaps around your chimneys and weather strip
around windows and doors.
6 - Install energy efficient ceiling fans. If it's just a little too warm for
comfort, use the ceiling fan without air conditioning. If it's hot enough to
require your air conditioning, using you ceiling fans will add even more
7 - A lighter colored house will not absorb as much heat and a
darker colored one. So if you're buying or considering repainting, choose
lighter colors for your exterior.
