Energy savings discussions always surface in the fall as we prepare our homes for the winter heating season. It is worth the time to review those efforts before summer's oppressive heat brings astronomical cooling bills.
Window Units
Change the filter on your window unit, and make certain it has adequate space to vent and drain. Consider replacing it if the Energy Star rating is below 8 - opt for a unit 13 or higher - to minimize cost. Think about the size of the area you are cooling. A small space is best served by a smaller unit. Larger units will increase your energy bill by working harder for shorter periods of time.
Maintain Your Central Air Unit
Change your filters regularly and ensure it has been properly serviced for peak efficiency. Those Energy Star ratings matter on central air units too. We know central air units aren't the most attractive things in your landscaping, but don't hide them behind bushes or a fence - they need space to disperse the heat. Crowding them can boost your bill up to 20%.
Plant Shrubs and Trees
Planting shrubs around the foundation serves two purposes. First, it keeps the sun from hitting the exterior of your home. Second, it serves as a sort of insulation to help keep the cool air inside your home. A shade tree's canopy can keep your home cool, too, if it helps to block the sun.
Buy a Thermostat Timer
Thermostat timers ensure your home is comfortable when you are in it. Leaving your thermostat at 78 all day is a waste if no one is there. The thermostat timer ensures your home is at your preferred temperature when you arrive home without running needlessly all day long.
Seal Up Cracks and Weatherstrip Openings
Keep all that cool air inside your home by applying weatherstripping and caulking around those tiny openings where heat can escape. Make sure your chimney flue remains closed, and keep the doors and windows shut unless absolutely necessary.
A Word About Windows
Storm windows may help keep cool air in, but consider new windows if yours aren't energy efficient. Double - or even triple - planed glass is preferred. If you can't afford new windows, you can apply a window glaze that will help reduce sun warming and can help keep your home cool. Keep the curtains drawn, too, to prevent the sun from heating your rooms. Awnings are an excellent way to keep the sun off your window glass altogether.
Minimize Appliance and Lights Usage
Leaving your PC on generates heat, as does your television, microwave, refrigerator and, of course, your lights. Make your air conditioner work less by minimizing the amount of work it needs to do. So turn off all household appliances whenever possible and reduce your number of trips to the fridge.
Modify Cooking Habits
Turn off the oven to keep cooling costs low during the summer. Roll out the grill and prepare dinner outside, use the microwave, or just stick with food that can be prepared on the stovetop.
