Heating and cooling is the single largest energy consumer in a home, and accounts for about 40% of the energy used in a home. Taking steps to ensure the unit is running as efficiently as possible can help lower cooling costs this summer.
These tips will keep your central air conditioning and heat pump units running efficiently:
Check the filter and change it if it’s dirty, or according to the manufacturer’s recommendation, to help keep dust from collecting on the evaporator coil fins. Keeping your filter clean can cut energy consumption 5- to 15-percent. Turn off the air conditioner before pulling the filter out so that the fan doesn’t come on and blow dust throughout the home. Be sure to position the new filter according to the air flow pointer usually printed on the side.
Clear leaves, grass, weeds, plants, and other debris that block airflow through the outdoor condensing unit, which is the outside unit in your yard next to your home. Anything that collects on the unit’s fins will block airflow and reduce its efficiency. Grass clippings thrown by the lawn mower are common offenders.
Clean the outdoor condensing unit with a water hose.
Check to make sure air vents inside your home are not blocked.
Close off unused rooms and closing vents in those rooms can help.
