Heating & Cooling Tips
No Cost
* Check the settings on the room air conditioner. Make sure the "fresh air" vent on the air conditioner is closed so you are not cooling outside air.
* Close drapes, blinds and shades to keep sun's rays out of the home during the warmer months.
* Close drapes, blinds and shades to help retain heat at night or during unoccupied periods.
* In the winter, reverse your ceiling fan motor so that the blades push air up toward the ceiling, where hot air normally rises. The fan will drive the warm air back down around the edges of the room, which can result in more even heating. Better heat circulation will help combat the problem of sweating windows that some homes experience in the wintertime because of condensation on the glass.
* Keep the fireplace damper closed when the fireplace is not in use. Closing the damper prevents up to 8% of furnace-heated air from going up the chimney. If the fireplace is never used, the damper should be sealed with weather-stripping and the chimney stuffed with fiberglass insulation. Remove this material from the chimney before a fire is lit in the fireplace.
* Move the room air conditioner. If possible, put the air conditioner in a north-facing or shaded window; direct sunlight reduces efficiency. Remove and store the air conditioner during the winter rather than keeping it in the window.
* Set the temperature lower in the winter when your home is unoccupied. Use a programmable thermostat to automatically lower and raise the temperature according to your settings.
* Set the thermostat as low as comfortably possible in the winter. The less difference between the indoor and outdoor temperatures, the lower your overall heating bill will be.
Low Cost
* Clean furnace filters monthly. Dirty filters restrict airflow and increase energy use. Keep the furnace clean, lubricated and properly adjusted to save up to 5% of heating costs.
* Install an ENERGY STAR programmable thermostat away from natural cool and hot spots. An ENERGY STAR thermostat can save as much as $115 per year, provide more flexibility than standard models and perform one or more of the following functions: Save and repeat multiple daily settings, which you can change when needed without affecting the rest of the daily or weekly program; store four or more temperature settings a day; and adjust heating or air conditioning turn-on times as the outside temperature changes.
* Remove and clean room air conditioner filters monthly. Dirty filters reduce the efficiency of the air conditioner.
Good Investment
* Consider installing a whole house fan. An attic whole house fan draws cooler air into the home and forces hot air out through attic vents. Use it when the air is cool outside, such as in the early morning. Whole house fans typically use about one-third of the electricity of a central air conditioner.
* Consider installing a whole-house evaporative cooler if you live in a dry climate. An evaporative cooler uses as much as 75% less electricity as an air conditioner, saving approximately $150 a year. For hotter desert climates, the savings can be much more.
* Consider planting trees and shrubs in strategic locations to help reduce the temperature and airflow in your house. Deciduous trees planted on the west and south sides of your home help to keep the house shaded during the season's peak heating times.
* Fireplace inserts or wood stoves are available to fit into an existing fireplace. These inserts are equipped with glass or metal doors, outside combustion air vents, and heat circulation blowers. Fireplace inserts dramatically improve fireplace efficiency by blowing heat from the fire into the room and limiting the amount of heat and conditioned air lost up the chimney. Fireplace inserts are recommended for fireplaces that are regularly used. Before installing a fireplace insert, be sure to check the manufacturer's safety specifications and make sure the fireplace insert is compatible with the existing chimney or vent flue.
* If you use electricity to heat your home, consider installing an energy-efficient heat pump system. Heat pumps are the most efficient form of electric heating in moderate climates, providing up to three times more heating than the equivalent amount of electrical energy it consumes. A heat pump cools your home by collecting the heat inside your house and effectively pumping it outside. A heat pump can trim the amount of electricity you use for heating as much as 30 to 40%.
* If your furnace is more than 15 years old, replace it with an ENERGY STAR qualified furnace, which is 15% more efficient than a conventional furnace. If you have a boiler, consider replacing it with an ENERGY STAR qualified boiler that is 10% more efficient than a new, standard model.
* If your heat pump is more than 10 years old, replace it with an ENERGY STAR heat pump, which uses at least 20% less energy than a standard new model.
* If your old central air conditioner is more than 10 years old, consider replacing it with an ENERGY STAR model, which uses 20% less energy than a standard new model. Look for a SEER rating of at least 12.
* If your room air conditioner unit is more than 10 years old, consider replacing it with an ENERGY STAR room air conditioner, which uses at least 10% less energy than a standard new model. Select the unit with the highest Energy Efficiency Ratio (EER) for greater savings. Ask a trained salesperson for help choosing the size that's right for your needs.
* Install glass doors on fireplaces, which act as a barrier against warmed air returning up the chimney. Some models of glass doors are equipped with small vents along the bottom or sides to allow a controlled amount of combustion airflow into the fireplace. The glass allows the heat from the fire to radiate into the room. Because glass doors reduce the amount of conditioned air that is drawn up the chimney, they also reduce infiltration of outside air into the home.
* Look for a room air conditioner with a filter that slides out easily for regular cleaning. Clean filters help keep the unit in good working condition.
* When buying an air conditioner, enlist the services of a qualified technician to ensure your unit is properly sized and installed for your home/building. A unit that is too large will not only cost you more up front, but will actually work less efficiently, costing you more to operate over its lifetime.
