Keep unoccupied rooms closed with localized heating or cooling, open your doors if your system is centralized.

If you have localized heating or cooling,(such as baseboard heating or a window A/C unit), and a room that's not in use, make sure to close the door and the vents so that energy is not wasted to cool or heat the room.

However if you have a centralized HVAC unit, open your internal doors to maximize your units efficacy. A centralized system is designed to move air through your entire home. When a room is closed air becomes trapped and pressurized, the pressurized air will escape from your home in any way it can. This puts extra strain on your HVAC unit and waste energy. 

Clear around radiators and vents

Furniture that is placed within 2 to 3 feet of the radiator will absorb the heat that would otherwise rise to circulate and heat the room. Don’t place anything on top of the radiator or position furniture or rugs directly on top of floor vents as it prevents air circulation.

Manually regulate your thermostat, or use a programmable thermostat

The Environmental Protection Agency (EPA) recommends that you set the thermostat to 68°F in winter when you’re at home and down to 65°F when you go to bed or when you’re away. In the summer, set the thermostat to 78°F for cooling.

When programmable thermostats are installed and used with the four pre-programmed temperature settings for weekend and weekdays, you can save about 10% each year on heating and cooling costs while staying comfortable. Programmable thermostats automatically adjust the temperature when you’re sleeping or when you’re away. Make sure to adjust your settings or program your thermostat for when you are going on vacation or changing your normal occupancy routine.

Use ceiling fans to supplement air conditioning and heating

Ceiling fans efficiently circulate air throughout a home during winter and summer.  They can increase the cooling effects of air conditioning so you can set your thermostat higher or not use A/C at all on mild days. In summer, run your fan counter-clockwise; in winter, run it clockwise so it pushes warm air up against the ceiling and down along the walls. For maximum energy saving benefits, purchase an ENERGY STAR® ceiling fan. These fans circulate an average of 15% more air than other ceiling fans.

Change HVAC filters on a regular basis

Air conditioning and heating can account for half of a household’s energy consumption. Changing your heating, ventilating, and air conditioning (HVAC) system filters regularly will allow the systems to operate efficiently, and will keep the indoor air clean. Use HEPA (High Efficiency Particulate Air) filters on your HVAC system so that you have maximum filtration in your home.

The frequency recommended for filter changes can vary depending on your household environment. Most homes should have a filter change every 90 days, but more frequent changes may be needed for homes with pets or during peak seasonal usage. A monthly visual check is enough to see if the filter is dirty and needs replacement. Learn more about changing your filter from the Service Experts guide or Energy Star® guide.

Have HVAC systems professionally evaluated and maintained

It is important to have your HVAC system evaluated and maintained, especially if you are living in a home with a pre-existing system. Annual, pre-season check-ups can ensure that your system is operating correctly and efficiently, and help to avoid costly maintenance problems. A typical check-up should include checking thermostat settings and system controls, lubricating moving system parts, and inspecting the condensate drain. Additional evaluations may be performed specific to the heating or cooling system being checked.
