Regular maintenance of your home heating, ventilation and air conditioning system (HVAC) is critical to ensure its long life and efficient operation. Proper maintenance of this system can help keep your loved ones safe from extreme temperatures —and may also help save you some money.
The HVAC system heats your home during the cold winter months and keeps your home cool in the sweltering summer. Regularly changing the HVAC air filter is critical for its long life. The air filter keeps pollution and debris out of your HVAC system, ensuring proper and efficient operation. A dirty filter will slow down the air flow, making both the furnace work harder to heat your home and your AC work harder to cool it. This wastes energy and can result in higher energy bills.
According to Energystar.gov, the filters on your home system likely need to be changed either once a month or once every three months, depending on the type you’re using. You should check the product information on the filters for the manufacturer’s suggested frequency of change. Depending on where you live, the time of year, and how much you’re using your AC or furnace, you may end up having to change your air filter more frequently. For instance, during a steamy summer when you’re running your system constantly, you may end up having to change the filter more often than if the weather is nice and you’re relying on open windows.
