Regular HVAC maintenance helps ensure not just clean indoor air, but also reliable HVAC performance. Part of its upkeep includes replacing its air filter. But have you wondered what happens if it’s not replaced? Read on as local air con specialist Kemnitz Air Conditioning & Heating Inc. shares a look at what can happen.

Why Do HVAC Systems Need New Air Filters?

According to the EPA, the levels of air pollutants in indoor spaces are often two to five times higher than outdoor levels. This, and the fact that most people spend up to 90% of their time indoors, require the need to remove indoor air pollutants before it gets into the HVAC system.

Air filters are a cost-effective and efficient way to do so, as they are made with material that can trap particles as small as viruses and microbes. Depending on the concentration of air pollutants in a space, air filters can get filled to capacity quickly, sometimes as fast as within a month during seasons of peak usage. Fortunately, they don’t need a service appointment with an AC repair technician, as most air filters are designed to be user-replaceable.

What Happens When You Don’t Replace Air Filters

Air filters can get clogged when filled to capacity, affecting airflow within the air ducts, even redistributing indoor air pollutants back into indoor spaces. The longer the clogged air filter remains in use, the following issues become more apparent:

• Increased energy bills. HVAC systems that struggle with airflow tend to run for longer hours, which equates to greater energy consumption.

• Respiratory problems. People who suffer from seasonal allergies and respiratory problems triggered by mold can greatly benefit from regular air filter replacement. For better filtration, you can upgrade to HEPA air filters, which can capture even smaller particles.

• Reduced efficiency. As described above, poor airflow can affect HVAC efficiency, which can increase the strain on the system and increase the risk of an early failure.

• Dust buildup. Dirty air filters can end up letting dust and other particles into the air ducts, defeating its purpose, which may necessitate more frequent air duct cleaning appointments. Ideally, air ducts require cleaning every five years — regularly replacing air filters can help make sure that air duct cleaning appointments are few and far in between.
