Regularly checking and replacing your HVAC filter is the best way to protect your system and help it run more efficiently. An HVAC filter removes particles, debris, and other contaminants from the air being pumped through your home's ductwork and air handler. These filters also protect your HVAC unit's internal components by keeping them free of dust and other materials that can cause buildup and slow the unit's performance. Ideally, HVAC filters should be replaced every 30 to 60 days depending on usage and climate conditions. If you notice your unit working harder than usual, or if the air coming from vents seems dusty or dirty, it's time to change your HVAC filter. In some climates, you may need to change your HVAC filter more often than others. It's also important to know when to throw away an old filter altogether and install a new one. This article will teach you everything you need to know about HVAC filters, including how to check them, how often they should be changed, and when they need to be replaced with a new one.
One of the first things to do when checking your HVAC filter is to locate where the filter is located. Your filter is likely located inside your air handler or on the outside of your home near the HVAC unit. If you're not sure where your filter is located, here's how you can check it:
When you check your HVAC filter, you'll know when it's time to replace it. The length of time you can use one HVAC filter before it needs to be replaced varies based on climate, location, and other factors. Here's what you can expect from your HVAC filter:
Dirty Filter - If your HVAC filter is dirty, it may be blocking air flow and causing other problems for your HVAC system. Your HVAC unit may have to work harder to push air through the filter and out of the home, which can lead to higher energy bills.
30-Day Filter - If your HVAC filter is dirty, you can install a new one within 30 days. You'll want to clean your filter more frequently if you live in a dusty or dusty-dry climate.
60-Day Filter - If your HVAC filter is dirty, you can install a new one within 60 days. You'll want to clean your filter more frequently if you live in a dusty or dusty-dry climate.
100-Day Filter - If your HVAC filter is dirty, you can install a new one within 100 days. You'll want to clean your filter more frequently if you live in a humid climate.
If your HVAC filter is dirty, you'll need to throw it away and replace it with a new one. However, you'll also want to know when it's time to throw away an HVAC filter even if it isn't dirty. Some filters can be reused, but others should be thrown away after a certain amount of time. Here's when you should throw away your HVAC filter:
Worn Out - If your HVAC filter is worn out, it may need to be replaced. Worn-out HVAC filters can cause your HVAC system to work harder to push air through the filter and out of the home. This can lead to higher energy bills.
Loose Fibers - If you see loose fibers in your HVAC filter, it's time to throw it away. Loose fibers can cause a buildup of dust and other materials in your HVAC system, which can damage your HVAC unit and cause other problems.
Buildup - If you see buildup in your HVAC filter, it may need to be replaced. Buildup can cause a reduction in airflow, which can cause other problems for your HVAC system.
Mold - If you see mold in your HVAC filter, throw it away. Mold can spread throughout your HVAC system and cause other problems.
Now that you know when to change your HVAC filter, you'll need to know how to install a new filter. Keep in mind that you'll need to clean the filter before you put it back in place. This will remove any debris and dust that may have collected on the filter. Here's how to install a new HVAC filter:
Turn off the power to the HVAC unit. This will help you avoid any damage that may occur if you accidentally shut off the power too soon.
Loosen the bolts that hold the filter basket in place. If you're replacing an old filter, you may need to remove the bolts. If you're installing a new filter, you may need to tighten the bolts.
Remove the old filter from the HVAC unit. You'll want to use a pair of channel-lock pliers to grip the filter and remove it.
Insert the new filter into the HVAC unit. Make sure the filter is fully inserted into the HVAC unit and there's no space between the filter and the unit. You may need to jiggle the filter to make sure it's fully seated.
Tighten the bolts that held the filter basket in place. If you're replacing an old filter, you may need to tighten the bolts. If you're installing a new filter, you may need to loosen the bolts.
Turn the power back on to the HVAC unit. Your HVAC system should be back to normal within a few hours.
