3 Ways to Know Your Air Ducts Need Cleaning

When you’re at work, while you may not notice if your HVAC is working efficiently, you certainly will when it stops. Whether the temperatures plummet and you’re all shivering in your coats, or they shoot up and everyone is vying for the only available fan, there will have been several signs that your HVAC unit was about to give up long before you had to call out commercial HVAC contractors Minneapolis MN. Here are three ways you can tell that it’s time to call in the professionals before it’s too late.

Inconsistent Airflow

Are parts of your office freezing cold while others are the perfect temperature? HVAC units are designed to distribute air equally around a room. If air is unevenly dispersed, there’s a chance you have a blockage in your unit, and it needs cleaning.


Air conditioning units are damp places, which makes them a hotbed for mold to grow and spread. Mold is a dangerous thing to allow to develop in an office space; mold spores can be toxic and can make your employees very sick. If you start to smell a musty, old scent that lingers, you could have a mildew problem on your hands. Mold growth can often require cleaning care by a specialist, so be sure to call out an expert right away.


Is your office dusty even after the cleaning teams have come around? If there is more dust gathered around your air vent, it’s a reliable indicator that your vent is blocked. The more blocked your vent becomes, the less efficient it will be, and it will have to work harder to get the job done. The more power it uses, the more your energy bills will be.

If your HVAC vents are blocked and need a good clean, reach out to an experienced HVAC professional and schedule a call-out. They’ll have your heating and cooling system sparkling in no time.
