11 Steps to Savings
- Air filter(s) MUST be clean. Check the manufacturer’s instructions for the filter you’re using and find out how often it should be replaced. Roughly 35% of service calls are caused by a dirty filter, as it causes the system to work harder and use more energy.
- If you have a variable speed or an energy saving fan motor, leave your fan in the “ON” position instead of “AUTO”. The outside unit will still cycle on and off as needed, but the fan inside will constantly circulate air. This will also maintain a more balanced temperature in homes with multiple levels. This is not recommended with an older furnace. If you’re furnace is 15 years or older, the thermostat should be left on “AUTO”.
- Have the system cleaned and checked every year. The dust that builds up on the outdoor coil can increase energy bills by 20%. The cost of the visit will nearly pay for itself each year.
- Continuing from #3, having the refrigerant pressures checked annually will keep the unit cooling better and lower energy usage.
- Keep the majority of registers open. It’s okay if you need to close a few, but keep it limited to no more than 10% of the total registers in the home.
- Do not block cold air returns. This restricts airflow and will cause the system to work harder, use more energy, and causes discomfort in the home.
- When setting your thermostat, consistency is important. It is not recommended to turn the thermostat up and down on hot days. Instead, find a temperature that you’re comfortable with (average is around 72 degrees) and leave it there.
- Consider having your duct work cleaned by a NADCA (National Air Duct Cleaners Association) certified company. It will reduce the amount of dust in your duct work and help the system run more efficiently.
- Keep blinds closed, and curtains and window shades drawn. Make sure your walls and ceilings are well-insulated, and storm windows and doors are air-tight. Limit opening doors and windows to prevent heat gain. A working attic fan is always a great way to help remove excess heat from the home.
- Never cover the outdoor unit with plastic or an air tight cover; this will cause it to rust.
- Keep grass & weeds away from the outdoor unit. If not done, this will cause airflow restriction.
These simple steps will help to lower the cost of operation, which will in turn help keep your money where it belongs….in your wallet!
