Tips to Save on Heating and Cooling

Change your air filters
Change your filters once a month during the heating and cooling season. If you have pleated filters, change them at least every three months. If you’ve replaced your air filters but your system still seems to be performing poorly, have it serviced by a licensed contractor.


Clear plants & brush away from your outside heating and cooling unit
Keep plants and brush at least three feet away from outside heating and cooling units so they can operate more efficiently.


Create an airtight thermal boundary
Your home’s thermal boundary—also called its “envelope” or “shell”—consists of its outer walls, ceiling, windows, doors and floors. Sealing your home’s envelope reduces drafts and helps prevent moisture problems. It can save you up to 10%* on your energy bill and keep you more comfortable during the hottest and coldest months of the year. Air sealing a home with gas appliances can cause safety issues and should be done by a professional.

Have your heating & cooling system serviced annually
Have your heating and cooling systems professionally serviced once a year to keep them running as efficiently as possible. If your system is older, consider installing a more efficient one. Take advantage of our HVAC Service program and receive a rebate toward the assessment and services performed on your equipment.


Install storm doors
A storm door creates a pocket of insulated air space between itself and your house’s exterior door. This reduces heat transfer into and out of your home, lowering heating and cooling costs.


Insulate your attic, walls & floors
Insulation is designed to resist heat flow, which reduces the amount of heat transferred inside your house during hot weather, and helps reduce heat losses when it’s cold outside. We recommend R-30 for the attic, R-19 for floors and R-13 for walls or local codes, whichever is higher. (Most homes built prior to 1978 were not required to have wall insulation.)


Keep doors & windows closed when using your heating or cooling system
There’s no need to heat or cool the outdoors. Save money and energy by keeping conditioned air inside where it belongs.


Keep your air vents free of obstructions
To maintain even temperatures throughout your home, keep air vents and registers clear of obstructions such as furniture, curtains and rugs.


Keep your supply registers open
Do not close supply registers in unused areas of your home. Keeping them open increases your system’s efficiency by allowing air to flow freely throughout the room and house.


Landscape with heating and cooling in mind
Well-placed trees around the house can provide natural shade and insulation, helping you save money and energy—between $100 and $250 annually—on your air conditioning costs.


Lower your thermostat for large gatherings
Lower your thermostat when large groups of people are expected during the winter. Because our bodies act as small heaters and humidifiers, a gathering will compensate for the lower setting.


Make sure your attic is well ventilated
Proper attic ventilation can reduce your energy consumption and increase your comfort during summer’s heat and winter’s chill. Natural air flow in the attic also keeps the roof decking cool and dry, extending the life of roof shingles. Be sure attic soffit, gable and ridge vents are not blocked so air flows freely through them.


Remember to turn off the vent fans
Turn off kitchen, bathroom and other ventilating fans as soon as they are no longer needed. In about one hour, these fans can pull out a substantial amount of warmed or cooled air.


Save up to $300 a year with an energy-efficient heat pump
If your heating and cooling system is older, consider installing a more efficient system with a higher SEER (Seasonal Energy Efficiency Ratio). The most energy-efficient way to heat and cool your home year-round, today’s heat pumps are easy to install and maintain.


Set your thermostat
Set thermostats at 78°F in the summer and 68°F in the winter. You can expect a 3-4% increase in energy use for every degree you set the thermostat lower in the summer and higher in the winter. Also consider installing a programmable thermostat, which will automatically adjust your home’s temperature settings when you’re away or sleeping—a benefit that can save you up to $100 a year.


Turn on your ceiling fan for summer savings
If you use air conditioning, a ceiling fan will allow you to raise the thermostat setting about 4°F with no reduction in comfort. During moderately hot weather, ceiling fans may allow you to avoid using your air conditioner altogether.

Use an electric blanket
Electric blankets save you money during the winter because they enable you to lower your thermostat setting. And, each degree you set your thermostat back saves you about 3-4% on heating costs. If you have an electric blanket, remember to use it wisely: Turn it off during the day and place another blanket on top of it to keep in the heat. Always follow the manufacturer’s instructions about covering it and securing the corners to your mattress.


Use heat-generating appliances when it’s coolest
Avoid using appliances that give off heat during the hottest times of the day as they will make your cooling system work that much harder. Cook your meals, wash your dishes and launder your clothes in the morning or in the late evening, when the demand on your cooling system is less.
