Clean Homes are Healthy Homes

Keeping your home clean is a great way to keep your family healthy. Excess dust, germs, and grime can weaken your immune system and cause sickness that could be easily prevented with frequent, thorough cleaning.

Mold is another pollutant that can severely impact your health and home, and it can easily thrive throughout your household. The DG Heating & Air Conditioning is here to teach you the most common places mold grows in your home, how to spot it, and how to prevent it.

Air Ducts

As HVAC specialists, we’ve come face to face with mold growth in air ducts many times. If your air ducts are too warm and too humid, mold will likely begin to develop quickly. These conditions could happen when:

  • Your HVAC unit is too big for your home, causing an increase in condensation.
  • Your AC is set to a very low temperature, increasing humidity.
  • Your ductwork has leaks, creating an imbalanced environment.

When you discover mold in your air ducts, it’s important that you trust professionals to take care of its removal. They will be able to diagnose what went wrong, solve the issue, and make sure the mold is properly cleaned up.

Showers and Tubs

It’s no secret that our showers and bathtubs see a lot of water every day. When this water sits on a ledge or shelf for an extended period of time, you’ll begin to experience mold growth. To prevent this from happening, be sure to use your bathroom exhaust fan while bathing to reduce moisture build-up.

Mold can also develop in loofahs, sponges, and shower curtains. Be sure to regularly inspect these items before use.


The attic can easily become a mold hotspot for many reasons including:

  • A leaking roof
  • Improper insulation
  • Poor ventilation
  • Kitchen, dryer, and bathroom fans are vented to the attic

If undetected, attic mold growth can spread to the rest of your home. Be sure to check your roof for damage, maintain good ventilation, and consider rerouting your vents to avoid excess moisture.

Take Action

Mold can be extremely dangerous to your home and health. Be sure to take action as soon as you spot mold growth to avoid spreading!
