Mold in your home is a serious issue that should be addressed quickly and with the help of a professional. Aside from random places mold might grow in your home, you can also have mold growing inside your heating and cooling system. If you notice mildew smells, have your home inspected by an HVAC contractor for mold. Call KS Services for an HVAC repair to check for unwanted mold that can affect your health and the performance of your system.  

Mold Environment

Before mold can take root in your home and begin to grow, there are certain things you can look for to prevent your chances of developing mold indoors. The conditions promoting mold growth are:

  • Where there is moisture present. If you have a water leak or high humidity levels in your home, mold can grow. Moisture is the biggest reason for mold to become an issue in a home.
  • Just like any living organism, mold has to have oxygen to grow.
  • Areas in your home that get warm are prime places for mold growth.
  • Mold can grow on food sources, such as wood, drywall, or cotton.
  • Dark areas are typical places for mold to grow.
  • The most common way for mold to grow in your home is if there are already mold spores present.

If mold spores are left in any of these conditions between 24 to 48 hours, mold will start to grow.

Causes of a Moldy HVAC system

  • Humidity: High humidity levels in your home are the biggest cause of mold growth in your home. Summer months are usually the time when humidity is at its highest. With regularly scheduled HVAC maintenance from KS Services, our NATE-certified technician can keep your system clean, so that it can control the moisture level in your home.
  • Condensation: While your HVAC units run, your system develops condensation through the air ducts. There can also be condensation in your drip pans that doesn’t dry out completely.
  • Poor ventilation: If your home is vented poorly, it causes pockets of stagnant moist air to form inside your home. Any steam or evaporating water in your air creates more humidity that cannot be circulated out because of poor ventilation.

Prevent a Moldy HVAC system

There are measures you can take to prevent mold growth inside your heating and cooling system. With these helpful tips and calling an HVAC contractor for mold issues, you can breathe fresher, healthier indoor air.

  • Replace your air filter on your system every three to four months. During HVAC maintenance, your filter is checked by an HVAC contractor for mold every time.
  • Insulate your air ducts to control the amount of condensation that is produced. Schedule an HVAC repair to have your air ducts insulated correctly.
  • Have your ducts inspected by a KS Services’ HVAC contractor for mold growth. If mold is present, our professional can clean your ducts during the HVAC repair.
  • Inspect your drip pans and make sure they are clean on a regular basis. This prevents condensation from building up, causing mold to form.
  • If you notice wet areas around your vents, registers, or air ducts, dry them within 24 hours.
  • If your heating and cooling system isn’t maintaining a healthy level of moisture in your home, you should consider buying a dehumidifier for your house.
  • Install ultraviolet lights in your unit to kill any mold or mold spores around your coils.
