According to the US Department of Energy, Americans spend more than $29 billion each year on air conditioning. There are several things a homeowner can do to keep their homes cool during the summer without increasing their bill.
1. Use a programmable thermostat : It is a good idea to use a programmable thermostat and raise the temperature when you aren’t home. This prevents the house from unnecessarily cooling when no one is home.
2. Turn on ceiling fans : If they are used in conjunction with an air conditioning system, the fans are very effective at lower your indoor temperature. In the summer, ceiling fan blades should rotate counterclockwise to push cool air down to the floor.
3. Postpone the use of appliances: There are three major heat generating appliances in the home; oven, dishwasher and dryer. It is best to use these devices in the evening rather than the hottest part of he day.
4. Keep the doors inside the home open : While in the winter, closing interior doors helps keep heat in specific rooms. Doing so in the hot summer months is detrimental to your cause. You want air to flow freely through rooms and throughout the entire home. Good airflow means a cooler home.
5. Change air filters regularly : Clogged filters will force the air conditioning system to work harder and use more energy, resulting in higher utility bills. Clean filters also improve indoor air quality.
6. Check the window coverings: Thermal drapes, cellular shades or blackout curtains will keep the heat outside and the cool air inside your home.
7. Schedule an air conditioner tune-up : Proper HVAC maintenance, which includes having a professional clean coils, ﬁns, air ﬁlters and check for the proper refrigerant charge, is the best way to ensure that the unit runs efficiently and effectively.
