Heating and air conditioning are usually the largest loads in a home and responsible for 40-50% off your monthly energy bill.
- Set your thermostat to 78oF in the summer and 68oF in the winter. A one degree increase or decrease can increase energy use by 3-5%.
- Install a programmable thermostat to save even more.
- When using the fireplace, turn down your heating system thermostat.
Heating and Cooling
- Change central HVAC system filter by manufacturer recommendation, or when dirty. Dirty filters can impact your home comfort and increase your electric bill.
- When installing new air filters, make sure they are facing in the correct direction of air flow (look for the arrow on the side of the filter).
- When heating or cooling, keep windows locked.
- Do not close off unused rooms that are conditioned by forced-air systems.
- Do not close supply air registers.
- Make sure outside soffit vents are not blocked.
- Do not use roof-top power ventilators for attic exhaust as they may draw conditioned air from your home.
- Have your HVAC system serviced yearly by a NATE-certified technician.
- Monitor your home's relative humidity in the summer. If it consistently stays in the 60% range or higher, ask your HVAC technician about lowering your central air conditioning unit's indoor fan speed.
- Remove and clean filters on window units monthly.
- Keep "fresh-air" vents on window A/C units closed.
- Ensure your outdoor heat pump/air conditioning unit is kept clean and free of debris.
- Ensure floor registers are not blocked with rugs, drapes or furniture.
- Run ceiling fans counterclockwise on medium to push cool air down.
- Close shades and drapes during the heat of the day to help your home stay cool.
- Turn off fans when not in the room. Fans cool people, not rooms.
- Plant trees and shrubs to provide shade on the east, south and west sides of your home.
- Minimize use of electric space heaters, except for limited or temporary spot heating. Turn space heaters off when leaving the room. An electric space heater can cost more than $100 per month to operate.
- Adjust ceiling fans to spin clockwise to bring warm air down.
- Open shades and drapes on sunny days to allow the sun to warm your home.
- Close shades and drapes at night to keep heat in your home.
- Remove window A/C units and close and lock the window.
- Use heavy-duty, clear sheets of plastic sealed tightly on the inside of windows to reduce the amount of cold air entering your home.
- When using the fireplace, open the outside air vent in the fireplace (if provided) or open the nearest window slightly. Keep fireplace dampers closed unless a fire is burning.
