Residential Retrofits

Conducting a self home energy audit helps a homeowner quickly determine areas within a home that waste energy. A self audit process should be made for each room and include a list of items inspected with problems found. All windows and doors must be closed, along with turning off exhaust fans and HVAC system.

Have you ever head of the TED The Energy Detective?
LEDS use about 1/10th the power of traditional outdoor light bulbs - so you can use much smaller (and cheaper) power transformers to power them. Lower power consumption also means lower electric bills Led also last much longer than traditional lighting sources!
Occupancy sensors or photo cells are a great option for a hands free system. You can even tie your lighting into your security system.

Ways To Save

Small Appliances

Clean or replace air filters. Replace filters on exhaust hoods, humidifiers, vacuums, etc. Clogged filters impair performance and cause the units to run longer. Run cold water for disposal. Hot water requires energy to warm the water. Cold water saves energy and solidifies grease, movin it more easily through the garbage disposal and pipes.

Refrigerators and Freezers

Purchase an ENERGY STAR model. When buying a new refrigerator or freezer, look for the ENERGY STAR label. ENERGY STAR refrigerators and freezers can save you hundreds of dollars on your electric bill over the life of the appliance. Remember, older refrigerators and freezers use two to three times more electricity than ones that are 10 years old or less. Select the right size. Determine your household's needs before purchasing a refrigerator or freezer. One that is too large wastes energy. Only use one refrigerator or freezer. You can spend up to $120 in electricity per year using a second refrigerator or freezer. If you want to use a second refrigerator or freezer during holidays or for special occasions, turn it on one to two days before you need it. Don't set the temperature colder than necessary. Set the refrigerator temperature between 36° F and 42° F. Set the freezer control so the temperature is between -5° F and +6° F. A small thermometer placed in the refrigerator or freezer will help you set it correctly. Clean the unit. Clean dust off the condenser coils, fins, evaporator pan and motor once or twice a year. A clean unit runs more efficiently. Unplug the unit and clean with a vacuum cleaner or long-handled brush. Do not place the unit in unheated space.


Run full loads. Always wait until you have a full load before running your dishwasher. Full loads use the same amount of hot water and energy as smaller loads. You run fewer loads and save energy. Use short cycles. Select the shortest cycle that properly cleans your dishes. Shorter cycles use less hot water and less energy. Clean the filter. If your dishwasher has a filter screen, clean it regularly. A clean appliance runs more efficiently.

Ranges and Ovens

Reduce the heat. Begin cooking on a higher heat setting until liquid begins to boil. Then, lower the temperature and simmer the food until fully cooked. A fast boil doesn't cook faster than a slow boil, but it does use more energy. Don't peek in the oven. Resist the urge to open the oven door while baking. Every time you peek, the temperature drops 25° F and requires additional energy to bring the temperature back up.

Washers and Dryers

Adjust the water level. If you have a washer that allows you to control the load's water level, adjust the level according to laundry load size. You can save energy by using less hot water for small loads. Run full loads. Always run a full load in your washer or dryer. Running a partial load uses the same amount of energy as a full load - but you get less done. Running full loads allows you to run your washer or dryer less often.

Water Heaters and Water Usage

Purchase an energy-efficient model. The initial cost may be more but operating costs are less in the long run. Consider a tankless or instantaneous water heater, which uses energy only when hot water is needed, rather than maintaining 40 gallons or more of hot water all the time. Look into alternatives like Tankless Waterheaters!


Use ENERGY STAR compact fluorescent light bulbs. ENERGY STAR compact fluorescent light bulbs last longer and use up to 75 percent less energy than standard light bulbs. You can cut your electric bill by $60 per year if you replace the standard bulbs in your five most frequently used light fixtures. Properly dispose of compact fluorescent light bulbs at your local household hazardous waste collection site.
Consider LED (Light Emitting Diode) lighting. LEDs are becoming more common for can, track, under-cabinet and holiday lighting. Initial cost is more, but the lights use 10 times less energy and last 50 times longer than incandescent lights. They use one-third the energy and last 5 times longer than compact fluorescent lights.


Use fans with your air conditioner. Fans help reduce energy costs by circulating the cool air from your air conditioner. This allows you to raise the temperature and still be comfortable. Use oscillating fans for greater circulation.
Maintain your fan. Keep your fan in good working order. Check the manufacturer's recommendations for care and maintenance. This helps control the operating costs.
