Common HVAC Issues That Make Your Home Dusty

Dusting is nearly top of the list of most hated chores for many people. After all, who likes watching all that grime accumulate on the rag or lifting each piece on a shelf to get underneath it? It’s a pain that we, unfortunately, have to deal with to keep a clean, safe home.

That said, if your home is excessively dusty, it might not be that you’re procrastinating, but your HVAC needs a little help.

How Can Your Home’s HVAC System Affect Air Quality?

Air conditioning systems, furnaces, and other HVAC systems are directly connected to the quality of air in your home. They take air in, whether hot or cold, and release filtered air, again.

When your HVAC system works properly, is installed professionally, and receives appropriate maintenance and repairs, the air quality in your home is clean and safe. However, any damage or pending repairs adversely affect the air in your home.

Indeed, quite a few HVAC issues can lead to a dense layer of filth throughout the house, and the exact source of the issue isn’t always easy to pinpoint. However, Furnace Doctors, your local Saint Paul Park HVAC contractor, can shed some light on the subject.

The Most Common HVAC Problems That Cause Dust

Let’s discuss a little more about three of the most common HVAC system problems that can leave your home drowning in dust.

1. Damaged Ducts

As the “highways” through which filtered air flows through your home, your ductwork is essential in how clean—or dirty—your residential indoor air quality is. It’s equipped with filters at critical points to police dust-causing particles, but when this system becomes damaged, these filters can’t catch what they need to catch.

One primary sign that your home’s air ducts may be damaged or malfunctioning is an unpleasant odor. Because ventilation is the critical purpose of your duct system, poor airflow causes mold growth, offering this smell up to you and your family.

Ducts can spring leaks from age or physical damage, and these leaks tend to be tricky to find. Air that hasn’t been filtered gains access to your ductwork through these gaps, thus distributing dust throughout your home.

Much like mold growth in your ducts, air from outside, and other homes or buildings, also gets into your home. This poses a danger to your entire family, not only those with asthma or allergies.

2. Filters With Low MERV Ratings

Air purification happens thanks to your HVAC system's physical filters—the large, frequently panel-shaped things that you need to check monthly for cleanliness purposes.

However, even if you're doing your system its due justice, your filter can still let dust-causing particles through if it isn't at a high enough MERV rating. According to the United States Environmental Protection Agency, MERV ratings "report a filter's ability to capture larger particles between 0.3 and 10 microns (µm)."

The higher this rating, the more potentially dust-causing particles your filter will catch, so if your home is dusty, it's possible your filter might not be up to snuff.

3. Systems That Blow Air at High Speeds

If you notice that your HVAC system is blowing air too fast, you’ve always felt the discomfort caused by this action. Thermal sensation from your HVAC system is affected by humidity, temperature, and air speed.

Typically, air blowing at excessive speeds is caused by oversized fans or excessive air duct pressure. Ventilation systems offer a greater control of airflow, so if you notice unusual air speeds, you may need an HVAC professional to take a look at your system.

4. Too Little Humidity Inside the House

Homes with humidity that is too low—air that is too dry, in other words—tend to have problems with dust. This is due to a variety of reasons, but one thing is for sure: You need a pro to install a whole house humidifier if your humidity levels are unbalanced.

Of course, dust isn’t the only problem with low humidity, as we covered in our HVAC services blog Why Is Managing Your Home’s Humidity Important?”
