Dealing with Mold in Your HVAC System

Mold can grow practically anywhere and everywhere in your home. However, it’s commonly found in HVAC systems, which presents significant problems for everyone in your family, particularly those who are allergic to mold growth. Why does mold grow in heaters and air conditioners, and does it necessitate HVAC repair in Grand Rapids, MN to set it straight? Continue reading to learn the answers to these questions and to learn everything else there is to know about mold growth!

Why does mold grow in HVAC systems?

Mold grows inside furnaces and air conditioners for several good reasons: moisture, food and the fact that it can grow and spread without being detected. The constant process of heating and cooling your home creates high levels of moisture that are never fully evaporated, making the system a perfect breeding ground for mold. Additionally, the mold gets nourishment from the organic material found in dust particles, which accumulate quickly in HVAC systems.

What are the signs?

If there’s one bit of good news regarding mold growth in your HVAC system, it’s the fact that you don’t necessarily need to look inside your AC or furnace to know that mold is present. The first sign you might notice is a musty odor throughout your home, as the mold spores are spread through your air ducts. You might even see mold around the outside of your AC unit or around your ductwork. Finally, if there are any big puddles around your HVAC system, you can bet that there’s a good amount of mold growing inside.

What are the dangers?

Though mold could technically prevent your HVAC system from working the way it should, that’s not the biggest danger when it comes to mold growth. You should be worried about the side effects on your health, including coughing, asthma attacks, headaches, bronchitis or even pneumonia. Though minor mold growth won’t cause immediate severe reactions such as these, mold spreads quickly and can take over your HVAC system faster than you think.

What can be done?

Even if you haven’t experienced any side effects yet, here’s what you need to do to combat that mold:

  • Regular maintenance: First and foremost, have your AC cleaned every spring, and your furnace cleaned every fall. In addition to cleaning, an HVAC technician can tune up your system and help you avoid the need for major HVAC repair in Grand Rapids, MN.
  • Change filters: Air filters are responsible for keeping the air inside your home nice and clean. However, they become less effective as they start to collect more dust and debris. Change or clean your air filter every month to ensure it’s as effective as possible.
  • Duct cleaning: As mentioned above, mold is also often found up in your air ducts. We recommend having those professionally cleaned every few years to eliminate any sort of threat.
