When And How To Change A Furnace Filter?

Filters in furnaces remove particles from the air before entering your heating system via return ducts. Eliminating these particles can help protect delicate components of your furnace (such as the blower motor) and enhance your home’s air quality. It’s important to change their HVAC system filters regularly to maintain the air quality. 

When Do You Have To Change The Air Filters?

Affordable Heating & Cooling, Inc. experts for heating replacement in Lasalle recommend that you change your furnace filter at least every 90 days. The filters with a higher thickness can hold dust and dirt and need not be replaced frequently. Specialists recommend changing smaller than two inches in thickness filters every 30 to 90 days. 

The filters of three or four inches can last between 6 and 9 months, and you should replace the filters of up to 6 inches in thickness at least once per year. Our experts for furnace installation in Lasalle, the air quality in your area could influence how often you should replace the furnace’s filter. 

Larger houses will have more significant amounts of air moving around, so the filter will require replacement more frequently. 

Smaller homes and vacation properties could require less frequent filter replacements. The most effective way to determine whether you’ll need to change your filter is to examine it. If it’s gray and covered with dirt and debris, it’s time to change. 

Dander and fur from pets will block the filter fast, and you’ll need to replace it more frequently. Switching filters every two months is sufficient if you only have one pet. If you have several cats and dogs, you should change the filter every three to six weeks.

Method To Change The Filters In Your Furnace

  • Determine Which Size Filter You Need: The first thing to determine is what type of filter you have. Once you’ve turned the furnace off, you must remove the old filter. It is located within the furnace or in the vent for air returns. You will see an indentation on the furnace filter that will show which direction the air is flowing.

    Our experts for furnace installation in Lasalle advise using a sticky notepad to indicate the airflow direction outside the furnace. So you’ll know the proper procedure to put in the filter. Once you’ve removed your filter, note its dimensions on the cardboard frame so that you know the size you need to purchase.

  • Find The Right Replacement: If you’ve decided on the size of the furnace filter, the only thing you need to do is to purchase it. You can usually purchase furnace filters from hardware stores, home stores, or the internet. 

  • Install Your New Filter: When you install the furnace’s new filter, you’ll notice markings indicating where the filter is supposed to be facing the furnace. Place the filter in place and then put the cover back over it. Please note the date you changed the filter to ensure you are aware of when you can alter it once more.
