Can You Change an Air Filter While It's Running? - A Guide for Homeowners

If you're a homeowner looking to replace the air filter in your heating, ventilation, and air conditioning (HVAC) system with a heat pump, it's essential to take the necessary safety precautions. Victor Belavus, an air conditioning specialist and owner of 212 HVAC, an air conditioning repair and installation company based in Brooklyn, New York, recommends disconnecting the power supply to the unit itself and also to the circuit breaker before attempting to remove the clogged filter. This will prevent air from introducing dust and sand into the system. Once the power is off, open the ventilation grille and remove the used filter.

Air filters are designed to capture large particles suspended in the air that can clog the system. Replacing your home air filter is a quick and easy way to keep your air conditioner, boiler, or central air system running efficiently.

Filters should be changed every 30 to 90 days

, depending on the type and efficiency of the filter. In addition to air conditioning and air conditioning units, Victor also specializes in furnace repair and air duct cleaning.

Before changing a household air filter in the air conditioning unit, it is important to turn it off to prevent injury or damage to the machine. A dirty filter can cause poor air quality and cause the system to operate inefficiently by reducing or preventing air flow, causing the entire system to work even harder to heat or cool the house (depending on the season). During peak winter and summer months, it is recommended to change the air filter every month. If you have an air filter in your basement, there is a chance that it will be exposed to moisture which can cause mold to form.

Once you have placed the new filter in its slot, check for gaps or any other signs that it is not properly adjusted. Keeping an air filter clean can keep energy costs low and reduce the risk of mold or bacteria growing in your air system. Air filters are usually available in multiple packages but before you make an investment, keep in mind that they are not universal in size.

Check your filter at least once a month

if you use it frequently and change it at least every 3 months.
