We always emphasize the importance of having annual, professional maintenance performed on your heating system in Cedar Grove, NJ. We also warn customers against DIY maintenance or repair, as this can injure you, damage your equipment, and void your warranty. However, you should regularly change the air filter to protect your heating system. Here’s everything you need to know.
Yes, Furnaces Have Air Filters
We’re not talking about an air filtration system for your home, to reduce germs and other particles and improve your indoor air quality. No, we’re just talking about a simple component of your furnace. It’s there to catch dust and grit before it can make its way into all the small and precise moving parts of the heating system itself.
If all that mess got into your furnace, it would blanket everything in an insulating coat of dust and grime. Friction between components and overheating from essentially wearing a fuzzy sweater would be the result. But if you let the filter get too clogged and dirty, it will prevent airflow. That can also cause overheating, system shutdowns, short cycling, wear and tear, and wasted energy.
How Often to Change the Air Filter
Most manufacturers recommend changing furnace air filters monthly. This is a good baseline to keep in mind. During seasons of light furnace use, such as spring and fall, the filter might not need to be changed quite as often. However, if your home has extra dust (renovations, deep cleaning, nearby construction, shedding pets), you should check the air filter more often.
How to Change the Air Filter
The first thing to do is turn off the furnace. Next, you need to know where to find the filter. It’s usually located in the blower compartment, which you can access through a panel door. Sometimes, you’ll find it where the air return duct connects with the furnace, often on the lower right. If you’re struggling, consult your owner’s manual or reach out to us with your questions.
To change out a disposable filter, simply slide the old one out, slide the new one in, and turn the furnace back on. You’re done! If you’ve got a reusable filter, it can be washed with water. Make sure it dries completely before you put it back in place. Again, turn the furnace back on, and you’re done. One tiny reminder: if there’s an arrow on the filter, make sure it’s pointing in the same direction as the airflow.
