Problems with Mold in the Air Conditioning Unit

A damp or musty odor is typically the first sign that mold is present in an air conditioner. Eliminating mold is a job best left to the HVAC professionals at Air Care Heating and Cooling.

Oftentimes, a Charlotte, NC, home that utilizes a window AC will see mold growth on the outside of the unit itself.

As tempting as it is to rid the unit of exterior mold, the more difficult issues often lie within. For this reason, it’s a good idea to let professionals take care of cleaning and eliminating mold problems in AC units of all types.

The Hidden Dangers of Mold in AC Units

Beyond the unpleasant odors that mold can create in a home, it’s also potentially detrimental to the health of the residents if left unchecked. Black mold spores can make their way into the air you breathe, triggering numerous health effects, including:

  •  Itchy eyes
  • Coughing
  • Skin rashes
  • Nasal congestion
  • Wheezing
  • Throat irritation

If you’re a homeowner who has a mold allergy, symptoms are often enhanced and can lead to more severe issues over time. Getting ahead of the problem by having a professional perform a thorough mold inspection and cleaning is essential.

The Causes of Black Mold in Home Air Conditioners

There are several reasons black mold might begin to grow in your AC unit. Sometimes, it’s simply a matter of underuse.

In the off-season, when temperatures are cooler, window air conditioners, in particular, sit dormant. During this time, dust and debris can collect within the unit and feed mold growth when paired with humidity.

Mold can also grow easily in AC units experiencing internal moisture pressure or a leak in the condenser. Cracks in the evaporator coil can also allow excess moisture to enter the unit and promote rapid mold growth.

Similarly, AC units with dirty filters are frequently found to have significant mold growth inside. If this is ignored, mold can spread across the unit and even be distributed through the air ducts in the home.

Simple Steps to Remove Exterior Mold

Above all, it’s important to have a professional technician take a look at your AC unit to pinpoint all areas of mold growth. In general, if mold has infested over two-thirds of the unit, it’s going to be necessary to invest in a new model to keep interior air quality at an acceptable level for health.

With that being said, if exterior mold is visible, particularly in window units, and you’re looking to remove it before an inspection, you’ll want to make sure to have the following supplies on hand:

  • Face mask
  • Protective eyewear
  • Non-porous gloves
  • Scrub brush
  • Mild detergent soap
  • Water

No matter what type of AC unit you’re removing mold from, make sure that you’re handling the job outdoors. Fresh air is the best way to combat mold spores that can be distributed when cleaning.

You’ll want to make sure to wear a face mask to protect yourself from mold in the air, while eyewear adds an extra layer of protection while you clean. Non-porous gloves keep mold from getting on your skin and should be worn whenever you’re coming in contact with AC mold.

Central Air Conditioner Mold Build Up

Charlotte, NC, homeowners who suspect they have mold growing in a central air system will need to contact the professionals. Even an exterior DIY cleaning won’t do much to reduce this problem.

Central air systems are intricate mechanisms, and at Air Care Heating and Cooling, our team knows how to tackle the job of removing mold without damaging other system parts.

Mold Prevention

Keeping up with regular maintenance and tune-ups is the best way to keep mold from growing in your AC unit. When technicians regularly have eyes on the system, they can stay ahead of any problems and likely extend the system’s lifespan as well.

Between maintenance appointments, make it a point to regularly check for mold buildup and vacuum any dust out of window units. Setting a system to fan mode can help remove any excess moisture during those times when the AC isn’t as needed.

Make sure to clean the AC filter regularly to deter mold buildup. Also, consider covering the unit with a weatherproof topper when your plans have you leaving home for extended periods.
