The wise use of energy plays one of the most important roles in that effort. But it requires a working partnership between those who supply energy and those who use it. Here are some ways you can help conserve energy and save yourself some money the rest of this summer. You cal dial II) aid hold y'our Costs down. Don't overcool your home. That's a wasteful use of energy. And expensive. For the most comfort and the most efficiency, set your thermostat no lower than about 10 degrees below the outside temperature. If it's 85 degrees outside, then set your thermostat at about 75 degrees. Otherwise your air conditioner has to work extra hard and your costs go up and up. In a typical house, you can save about 5 percent in operating costs for every degree you move the thermostat up. So, if your house is going to be empty for a few hours, move your thermostat up 5 more degrees and pocket the savings. Staying comfortable this summer can be a breeze. When the sun beats down, the heat in your attic builds up and it can be like living under an oven. An attic exhaust fan will get the hot air out and let the cooler night air in, and take the strain off your air conditioner. Good attic insulation works wonders at keeping your home cooler in summer and it will pay off again by saving on heating costs next winter. And don't forget light- colored shingles reflect heat. Whatever you do to keep heat out of your house saves money in air conditioning. Window fans work, too. Shades of the past. Before you had air conditioning, there were things you did to keep comfortable, like pulling down the window shades and closing the draperies on the sunny side of the house. That's smart. Because a bare window lets in as much as 35 times more heat than an insulated wall. So do the same now and you can reduce your air-conditioning costs by as much as 12 percent. Shade your windows from the outside with ventilated awnings or trees and save even more-up to 22 percent of your air-conditioning operating costs. Maintain your cool. If you want your air conditioner to take good care of you, keep it clean. This means changing or washing the air filters often. Also, vacuum the inside coils and keep outside coils free of debris. Clean registers and return ducts regularly on central air-conditioning systems, and keep the cooling drain open for free condensate flow. And don't block air flow with furniture or draperies. Your owner's manual lists other maintenance tips. Follow them and keep cool all summer. Buying a new air conditioner- Maybe the most important numbers aren't on the price tar. First of all, it's important that you get the right size unit (BTU's). Your salesman can help on this if you tell him the length and width of the area you want to cool. Another number that's important is the EER number. This stands for Energy Efficiency Rating. 0 MODEL NUMBER ACR2OB 74F VOLTS CYCLE PHASE 115 60 1 COOLING BTU/HR AMPS WATTS 6400) 75 8O7 j BTL~s WATTS You can figure this out yourself. Just divide the BTU number by the number of watts. For example, a unit that delivers 6400 BTU's with 800 watts has an EER rating of 8. (800 goes into 6400 8 times.) The recommended EER number for any air conditioner is 8 or more. You may pay a little more, but you'll save on energy costs in the long run.
