How To Clean Mold in Air Conditioner

Finding mold in air conditioner motors, circuit boards, and filters can be alarming. Fungi can multiply rapidly, reducing your appliance’s energy efficiency and service life. Severe mold outbreaks may even necessitate a total system replacement.

In the following article, Lubbock’s AC maintenance experts at On the Double! Heating & Cooling explain how to keep your air conditioner in pristine condition. This way, you won’t need to worry about expensive repairs for moldy or broken components.

How Does Mold Develop Inside of an Air Conditioner?

Mold and mildew thrive in moist, dark environments. Consequently, air conditioning drip pans, ventilation ducts, and refrigerant coils are vulnerable to these harmful elements. Knowing how to identify the at-risk areas in your air conditioner unit can help you clean and avoid mold in the future.

Here are a few examples to consider:

  • Refrigerant Leaks: The refrigerant coil enables the transfer of cool air into your home. However, pest activity, wear and tear, and storm damage can cause this coil to leak liquid. Pooling refrigerant can attract mold within just a few days and corrode other internal components.
  • Water Damage: Rain and snow can collect in the gaps and cracks of your window AC unit. As a result, mold may creep onto the surface of your appliance.
  • Dirty Air Filters: When was the last time you replaced your AC’s air filter? Visible mold may grow on the surface of this internal component, creating a significant health hazard. You might experience acute or severe respiratory problems by ignoring this issue.

Safe Cleaning Methods To Remove Mold From an AC

Here is a step-by-step guide to eliminating mold in air conditioners without stress:

  • Identify the Mold Problem: Before you can clean your air conditioner, you must identify the source of the problem. If you find mold in your air filter, replace it. Alternatively, if a refrigerant leak causes a mold outbreak, hire a professional HVAC technician for replacements.
  • Use the Proper Tools: You want to avoid using harsh chemical cleaners on your air conditioner’s electronics and coils. These products can corrode your appliance, leading to premature malfunctions and performance issues. Instead, fill two separate bowls of hot water and distilled white vinegar, keeping a vacuum and non-abrasive cloth nearby.
  • Wear Protective Gear: Turn off your HVAC system to avoid electrocution while you clean. It’s also wise to wear a mask and latex gloves to reduce the chance of mold exposure and inhalation.
  • Prepare Your Cleaning Solution: Mix a one-to-three ratio of hot water and distilled white vinegar into a bowl and vacuum debris from the surfaces of your appliance.
  • Soak and Wash the Unit: Use your non-abrasive cloth to absorb your cleaning solution and wipe away mold from affected surfaces. Let the cleaning solution sit for half an hour, then wash it away with warm water.
  • Dry Your Appliance: Always let your AC unit dry before turning it back on to prevent mold growth from reoccurring.

Preventing Mold Growth in the Future

Explore the following tips to avoid mold after you clean.

Monitor Your Temperature Settings

Set your AC to a reasonable temperature (professionals recommend 70-80 degrees Fahrenheit). This method prevents overperformance issues that cause leaks or excessive condensation from forming in your unit. Keeping your surfaces dry is an excellent way to avoid mold in air conditioners.

Check Your Vents

Mold can grow in hard-to-reach areas like your air ducts. In this situation, it’s best to hire a professional HVAC technician to inspect and repair your vents. They can eliminate spores and treat your vents with house-safe products to resist mold growth in the future. They can also inspect your outdoor units and mini-split systems if your home does not have an extensive ventilation network.

Upgrade Your HVAC System

Mold can eat away at old air conditioners, costing you hundreds in frequent repairs. Upgrading your home with a modern and durable HVAC system can help you prevent mold outbreaks in the future. Ask your HVAC technician for professional recommendations before you commit to a new installation.
