What Happens If You Don't Change Your HVAC Filter?

July 15, 2022 | Blog

Your HVAC system is a complex piece of machinery. Your system’s air filter is a tiny component, but it plays a massive role in your unit’s performance! Changing your HVAC filters regularly is necessary to prevent any future problems.

The Channell Heating and Cooling team wants to keep your system running smoothly! Read ahead to learn why you should change your air filter routinely.

What Does an Air Filter Do?

HVAC filters are made of different materials, usually thin fiberglass, polyester, or cotton. They clean the air that passes through your heating and cooling system. Filters trap harmful airborne particulate, such as:

  • Dust and dander
  • Pollen
  • Mold
  • Animal fur
  • Dirt
  • Gases
  • Pesticides
  • Bacteria and other microorganisms

These contaminants are bulkier than the air that passes through air filters, causing them to become trapped. Your AC redistributes the clean air into your home, keeping it healthy and breathable!

Consequences of Not Changing Your Air Filter

Unfortunately, air filters do not last forever! If you aren’t regularly changing your HVAC filters- the consequences could be costly.

Causes Wear and Tear on AC Unit

Clogged air filters are one of the most common causes of malfunctions in your HVAC system. Dirt buildup can cause the fans in your air conditioner to work harder and increases the possibility of breakage.

Buildup can also cause physical stress to your unit motors. These issues can shorten the lifespan of your HVAC system, enhancing the need for AC repair.

Increases Energy Bills

Dirty filters prevent air from flowing through your system, causing it to work harder. Your air conditioner may have to run for extended periods to cool your home. The increase in energy drives up your energy bill, costing you more money.

Lowers Indoor Air Quality

Air filters remove contaminants from your household air. If you are not regularly changing your HVAC filters, your household members will continue to breathe in harmful air. These materials can also accumulate in your home’s ductwork, compromising the efficiency of your HVAC system.

Poor indoor air quality can be the root of various illnesses. Breathing in unhealthy particles can cause watery eyes, headaches, respiratory irritation, and more. These symptoms are often a sign of sicknesses. Contaminants can also trigger asthma attacks with consistent exposure.

Poor Temperature Regulation

Debris buildup in your AC filter makes it difficult for air to pass through. As a result, air cannot properly circulate through the vents. Improper airflow makes it difficult for your home to remain cool, making it uncomfortably warm indoors.

So, if incorrect temperatures persist after changing your air filter, there may be a problem with your system. Professional AC maintenance can correct the issue to help cool your home.

How Often You Should Replace Your Air Filter

Professionals recommend changing your air filter every 2-3 months. If you have pets in your household, it may need to be changed sooner. You can inspect your filter to assess whether or not you should replace it.

Very Thankful for Their Service

They installed our old system and took care if all maintenance since 1995. This year it finally needed replacing. They installed a quality Trane system and it’s been running efficiently ever since. Very thankful for their service.
