Summer Time Energy-Saving Tips


These tips are designed to help you choose effective ways to reduce your energy bills. Some measures may not be relevant depending on climate, the age of your home and appliances, and past improvements made to your home.

Cutting back unnecessary energy use is an easy way to reduce energy consumption while saving money. Here are some additional suggestions you can do at home, at absolutely no cost to you.

Buying a bigger room air conditioner won’t necessarily make you feel more comfortable during the hot summer months. In fact, a room air conditioner that’s too big for the area it is supposed to cool will perform less efficiently and less effectively than a smaller, properly sized unit. The reason: an oversized unit will cool the room(s) to the thermostat set-point before proper dehumidification occurs, making the area feel “clammy†and uncomfortable. Central air-conditioning systems need to be sized by professionals.

Turn up your thermostat

Set your thermostat to 78 degrees when you are home and 85 degrees or off when you are away. Using ceiling or room fans allows you to set the thermostat higher because the air movement will cool the room. Always take into account health considerations and be sure to drink plenty of fluids in warm weather. (Save: 1 – 3 percent per degree, for each degree the thermostat is set above 72 degrees)

Inexpensive Energy Solutions

Make a quick trip to your local hardware store to purchase inexpensive energy-saving tools and equipment.

Replace air conditioner filters

Dirty filters restrict airflow and can cause the system to run longer, increasing energy use. Replace filters monthly for maximum benefit.

Plug your home’s leaks

Weather-strip, seal, and caulk leaky doors and windows and install foam gaskets behind outlet covers.
