There are a number of things you can do to trim heating bills in the winter and keep your cool in summer. Make sure hard-won comfort stays indoors by bulking up insulation, sealing leaky ductwork, and adding new weatherstripping to drafty doors and windows. Create climate control with a programmable thermostat. Keep heating and cooling systems in tune with annual service inspections, and be vigilant about changing filters. And if you’re able, begin replacing inefficient windows with Energy Star qualified models, which will improve your home’s value as well as its indoor climate.
