AC Smells Musty? Here Are 5 Things You Can Do

When the first hints of summer appear, we turn to our trusty air conditioners for relief. But sometimes, instead of a wave of cool, clean air, we’re greeted with a musty odor that’s anything but refreshing. At Indoor Air Quality, Inc., we understand that an air conditioner that smells musty is more than a minor nuisance—it can be a sign of underlying issues that may affect your home’s air quality and your system’s efficiency.

Let’s explore the causes of this common problem and uncover the solutions to keep your Denver home’s air fresh and clean.

Identify the Source of the Mustiness

• Condensation and Moisture:
  Excess moisture within your AC unit can lead to mold and mildew growth, thus creating that unwelcome musty smell.
• Dirt and Debris:
  Over time, your air conditioner’s filters and coils can gather dust and organic matter, which can start to decompose and emit odors.

Effective Solutions to Combat Musty Air Conditioner Odors

1. Routinely Replace or Clean Air Filters

• DIY Task:
  Check and replace or clean your air filters every 1-3 months, depending on usage.
• Professional Service:
  Schedule regular maintenance with Indoor Air Quality, Inc. to ensure your filters are always in top shape.

2. Clean the Condensate Drain Line

• Regular Checks:
  At least once a year, inspect the condensate drain line for clogs that can trap moisture and cause mustiness.
• Preventive Maintenance:
  Have our NATE-certified technicians clear the line and treat it with anti-algae products as needed.

3. Inspect the Ductwork

• Seal Leaks:
  Leaks in the ducts can introduce moisture from unconditioned spaces, leading to odor issues.
• Professional Duct Cleaning:
  Consider having your ducts professionally cleaned if there is significant visible mold or debris inside them.

4. Monitor the Coil and Evaporator

• Coil Cleaning:
  Dirty coils can harbor fungus and bacteria. Cleaning them can often eliminate the source of the smell.
• Expert Handling:
  Our skilled team can carefully inspect and clean the evaporator coil, utilizing the latest in HVAC advancements to maintain the peak performance of your system.
