Importance of Filter Changes

Importance of Filter Changes

Changing your air filter is one of the most important things you can do for your system. Not only do the air filters filter out pollen and dust particles from the air, but they also protect your HVAC system from getting things like bits of insulation pulled into your system and causing damage. A clogged air filter is the number one cause of HVAC failure, so it is vital to change your air filters regularly.

All the air handled by your HVAC is pulled through these filters at one point or another. Over time, more and more particles such as dust, mold, fungal spores, and pet dander are accumulated on the filters, which begins to block the air flow into your HVAC system. Once your air filter becomes clogged, your HVAC system has to work harder to keep up.

HVAC System Damage with a Dirty Air Filter

System has to work harder: The blower fan has to work harder to push the air. This causes the system to pull more energy and puts strain on the system.

Risk of overheating: The air can’t blow out of the HVAC system easily, which can cause it to overheat or freeze up.

Bacteria Growth: The particles on the dirty air filter can cause moisture to collect and mold or bacteria can begin growing. This can cause the filter to become even more clogged and send harmful allergens into the air. It can also damage parts of your HVAC system.

Dirty Air Ducts: When your air filter is dirty, particles can settle in onto the air ducts which puts a strain on your HVAC system.

Benefits of a Clean Air Filter

Clean Air Quality: Your air filter’s primary goal is to keep harmful particles and contaminants out of the air. Changing the air filters regularly will reduce allergies and reduce risk of airborne contaminants such as mold and bacteria.

Save Money: When an air filter becomes clogged, the HVAC system is put under strain and is no longer running efficiently. The air flow is restricted, causing the system to work harder to maintain the desired temperature. The HVAC system requires more energy, therefore increasing your utility bill.

Increase Life Span: Changing air filters regularly keeps your HVAC system clean. This prevents unnecessary wear and tear on the HVAC system components.

When to Change Your Air Filter

Typically, your air filters should be changed every month. Air filters are normally inexpensive and easy to replace. Check your unit’s specifications for the correct filter size and minimum efficiency reporting value (MERV) before replacing.
