Heating tips

Here are some low- and no-cost ideas of things you can do to reduce the amount of energy it takes to heat your house.

             Make sure heat vents and return air vents aren't covered.

Change your air filter at least twice a year and have your furnace cleaned and serviced during the heating season. 

Set the thermostat at a maximum of 68 degrees. 

Set back the thermostat a maximum of 10 degrees at night, unless you have a heat pump or cable heat. Save up to three percent on heating costs for every degree your thermostat is lowered. Consider installing an automatic setback thermostat for your furnace. 

If you have zonal heating (thermostats in each room) you can turn down the heat to 50 or 55 degrees and close doors. 

If you suspect your thermostat is not accurate, place a thermometer nearby and see if they record the same number. 

Weatherstrip and caulk around all doors and windows. 

Keep dampers closed when fireplace isn't in use. Unblocked, a good chimney can draw up to 20 percent of the warm air out of the house each hour. 

In cold weather, keep drapes and shades open on sunny days and close them at night.

The cost of heating your home is usually the biggest energy cost in a household.

Cooling tips

Here are some ideas for saving energy on air conditioning:

Set air conditioning at 78 degrees or higher.

Close drapes on the sunny side of the house.

Keep windows open at night and close in the morning before it warms up.

Add bamboo or vinyl blinds outside sunny windows to block heat transfer.

If inside draperies are used to shade the window, there is still considerable heat buildup in between the drapes and the window. If nothing else does the job put aluminum foil on the window.

Plant trees and shrubs to shade south and west-facing windows.

For a quicker solution add a lattice screen with a vine plant on it. Make sure the screen is far enough from the house wall to keep the plants off the building.

Self-adhesive window tints can be cut to fit most standard windows.

Also available are movable shades in dark-tinted mylar that roll up like a fabric window shade.

Use cross-ventilation.

Open a window high on one side of your house and another one low on the other side. This will promote natural cross ventilation. Do this in the cool of the early morning or evening.

Use the kitchen and bathroom exhaust fans to help pull cool air through. The furnace fan helps circulate cool outside air around the house.

Keep windows closed during the heat of the day.

Avoid cooking indoors to keep oven and stove heat from contributing to the home's temperature.

Re-schedule baking and broiling to a cooler time of day. If you have to cook indoors, use the kitchen range hood to help vent away hot air.

Keep lights off when possible.

A 100-watt standard light bulb puts out about 90 watts of heat and halogen torchiere uplights are equivalent to small space heaters. Change as many lights as you can to cooler operating fluorescent and you'll reduce the lighting-related heat in the house.
