Keep your thermostat at the lowest comfortable temperature setting. You can save about 3 percent of your heating costs for every degree you lower your thermostat during the winter.

If you don’t have a programmable thermostat consider getting one. These easy to use “smart” thermostats can change your home’s temperature up to four times a day.

Add a humidifier to your system to give you greater comfort at lower temperature settings.

Clean or replace your filters regularly. This should be done at least once a month during peak winter usage. Filter maintenance is a breeze with Trane’s innovative hinged door design on all 80 upflow furnaces.

14 of the best Summer Cooling Tips

Set your thermostat to 78. Go higher, if the humidity is low enough and you feel comfortable. Turning a thermostat down to cool a room quicker doesn’t work, by the way-it makes the a/c run longer, not colder.

Wear short-sleeved, loose clothing. You dress lightly to go out on a summer day. Do the same indoors. Absorbent, wickable cotton (organic, of course!) is the hot weather classic.

Drink lots of water. This is good practice, anyway. Cold drinks drop your body’s core temperature and cools you down quickly.

Draw your drapes. Keeping you blinds, shades, and curtains closed-particularly on the west side of the house-helps keeps heat from getting inside in the first place.

Turn off unnecessary heat-producing devices. Incandescent light bulbs are a big heat generator. Shut down electronic gear when you’re not using it.

Use the microwave. Conventional cooking dumps heat in the house, but microwaves cook the food directly.

Wash and dry clothes when the day is cool. Do laundry early in the day and late at night. Don’t forget clotheslines: they generate no heat in the house.

Skip your dishwasher’s dry cycle. Rack your dishes and let them air dry, instead.

Open the bathroom window when showering. Vent heat and humidity outside, rather than back into the house. Obviously, you don’t want to put on a show for the neighbors. If you have privacy concerns, open up after dressing. Keep the bathroom door closed.

Run your air conditioner fan on low. this is particularly helpful in areas with high summer humidity. the low air volume helps your a/c dehumidify.

Keep heat-producers away from your thermostat. Don’t allow a closely located TV or water heater to convince your thermostat that it’s hotter than it really is.

Check your refrigerator settings. The fridge takes heat out of your food and transfers it to your kitchen, so be sure you’re running efficiently. The refrigerator is best set between 37 and 40 degrees Fahrenheit. Put the freezer around five degrees.

Turn off your furnace pilot light. You can always re-light it next autumn.

Close the fireplace damper. Don’t send cool air up the chimney. If your fireplace has a glass door, shut it.
