"Why is my AC blowing dust?"

If you’re local, you can seek our professional AC repair services in Cedarburg, WI. In the meantime, consult our post below to learn why your air conditioner’s dust problem isn’t one to ignore for too long. 

Why Excessive Dust in Cedarburg Houses Reveals a Serious HVAC Problem

You can't escape dust; it's in every Cedarburg home in various concentrations. Still, you don’t want to breathe in these particles day after day. Dust isn’t harmless, as it potentially contains contaminants and particles, including: 

• Lead
• Decaying insects
• Lint
• Soil
• Smoke particles
• Pet dander
• Soot
• Carpet fibers

PFAS, a family of chemicals, may also be present in dust in carpets, waterproofing materials, nonstick coatings, and even in the air. Prolonged exposure to these common household contaminants can trigger anything from hormonal changes to cancer, which is why inhaling too much dust can be hazardous to your health. Excessive dust levels coming from your air conditioner also negatively affect your indoor air quality, leaving you with an unhealthy home environment.

Reasons Air Conditioners in Cedarburg Properties Blow Dust

Why is my AC blowing dust throughout my Cedarburg home? One or more of the following situations could be the reason for your property's poor indoor air quality:

Your HVAC Filters Are Dirty

One thing Cedarburg homeowners should remember about their cooling systems is that air conditioners need consistent airflow to work efficiently. Clogged air filters are problematic since the HVAC filters are responsible for trapping airborne particles as air passes through the air conditioner. This component isn't self-cleaning, so it needs replacement or cleaning to deal with the PFAS chemicals, dust, dander, and other particulates that stick to the filter over time. 

Replacing your HVAC filters regularly is essential for dust buildup prevention. Inspect your home's filter at least once a month. If the medium appears filthy or clogged, replace it. 

Why not invest in filters with a higher MERV rating? Highly rated filters trap smaller particles. 

Your Ductwork Is Leaky

You may assume that having a duct leak only means that a reduced amount of conditioned air is reaching the rooms. However, ductwork leaks can also contribute to dust accumulation in your Cedarburg home.

The leak may pull in contaminated air from its surrounding environment. For example, ducts sit in attics, basements, and behind walls, so their surrounding environments are naturally dusty. If dirty air is bypassing the filter by getting into the ducts this way, it’s also spreading into your living spaces right through the vents.

Your Ducts Are Dirty

Why is my AC blowing dust? It could be due to dirty air ducts. Debris can settle inside air ducts and line them, meaning that every time the air conditioner runs, the dirt will blow out along with the conditioned air. 

Households with pets or family members with allergies should schedule professional ductwork cleaning every two to three years. Everyone else may be able to schedule this service every three to five years for similar results. 

Your Intake Vents Are Filthy

All vents in your home could collect dirt and dust over time. However, in a Cedarburg home, the intake vent is usually the dustiest. It sucks air into the air conditioner, so it's not uncommon for dirt, dust, dander, and pet hair to build up inside this intake vent and start restricting airflow. 

Any airflow restriction is a problem. Blockages have an adverse effect on an air conditioner's performance and efficiency. You might notice that your house appears dustier than usual. 

You Need To Upgrade Your HVAC System

Sometimes, cooling units blow dust because they’re inefficient. Does the unit need repairs? Have you possibly skipped routine HVAC maintenance? 

If your system is over ten years old, a complete system replacement may be the best option.
