Filters: Replace or clean furnace filters once a month during the heating season. Dirty filters restrict airflow and increase energy usage. Consider a permanent filter. Electostatic filters are better at controlling the bacteria, mold, viruses and pollen that cause illness and irritation. Another good choice is a genuine HEPA filter. Be sure your furnace is in good working order. Many utility companies or heating/cooling contractors offer free or reduced cost annual checkups by qualified technicians.
Ducts: Studies show 10% to 30% of heated (or cooled) air in an average system escapes from the duct work. Hire a professional technician to come out and test your system. Properly sealed ducts can save the average home up to $140 annually.
Thermostats: Most households shell out 50 to 70% of their energy budgets on heating and cooling. For every degree you lower the thermostat during heating season, you’ll save between 1 and 3% of your heating bill. Programmable thermostats are available for as little as $50, and the average family will save $180 a year with one.
Insulation: It is one of the best ways to save energy. It can make a big difference to add more insulation between walls, and make sure your attic insulation is adequate.
Counterclockwise rotation is for cooling breezes while switching to clockwise makes it warmer: air pooled near the ceiling is circulated back into the living space – cutting your heating costs as much as 10%.
A/C and Water Lines
Drain any hoses and air conditioner pipes. If your a/c has a water shutoff valve, turn that off. Don’t forget to remove any window A/C units to avoid cold drafts all winter. Make sure any hoses are drained and stowed away. Turn off exterior water spigots.
Many conventional water heaters are set to 140 degrees F by installers. By lowering the temperature to 120 degrees F (or lower) would reduce your water heating costs by 6% to 10%. Pay less for hot water by insulating your pipes and hot water heater. You can get pre-slit pipe foam at most hardware stores. Cut it to size and fasten in place with duct tape.
Storm Doors and Windows
Installing a storm door can increase energy efficiency by sealing drafts. Storm windows can make a huge difference when the cold wind starts blowing. It is worth it to get your storm windows installed for the season.
