SplitClean provides professional air conditioner cleaning services, specializing in the deep cleaning and sanitizing of mini-split and ductless AC indoor units, as well as HVAC coils. Our focus is on cleaning the indoor unit to remove mold, bacteria, dust buildup, and odor-causing contaminants that affect air quality and system performance.

With SplitClean, you can enjoy cleaner, healthier air that supports overall wellness by improving indoor air quality. Without regular professional cleaning, mini-split and ductless air conditioning units can become a breeding ground for mold, mildew, bacteria, and other airborne contaminants that may contribute to allergies, respiratory issues, and unpleasant odors.

A clean air conditioning system doesn’t just improve health—it also improves efficiency. Removing buildup from the indoor unit and coils allows your system to operate more effectively, helping reduce energy consumption and extend the lifespan of the unit. We take pride in delivering prompt, professional service and completing every job to the highest standards for both residential and commercial properties across Brooklyn and New York City.

1. Lower Your Energy Costs
A dirty air conditioner or mini-split heat pump can increase energy usage by up to 30%. When filters and coils become clogged with dust, debris, and buildup, the system has to work much harder to cool or heat your space. This extra strain causes higher power consumption and increased electricity bills. Keeping your air conditioner clean allows it to operate efficiently, helping reduce monthly energy costs and improving overall performance.

2. Reduce Health Risks from Microbial Contamination
Mini-split and ductless air conditioning units can become breeding grounds for mold, mildew, bacteria, and fungi when they are not properly cleaned. These contaminants are then circulated into the air each time the system runs, potentially triggering allergies, asthma, respiratory irritation, and unpleasant odors. Regular professional cleaning removes these harmful contaminants from the indoor unit, helping maintain cleaner, healthier indoor air.

3. Extend the Life of Your Air Conditioner
Just like any mechanical system, your air conditioner benefits from regular maintenance and cleaning. Skipping routine cleaning can lead to excessive wear, reduced efficiency, and premature system failure. A well-maintained mini-split or ductless AC unit will last longer, perform more reliably, and help you avoid the high cost of early replacement.
Regular professional cleaning is a simple step that leads to a more efficient, healthier, and longer-lasting air conditioning system.

Foul or Musty Odors
A dirty-sock or cheesy smell coming from your mini-split is a common sign of mold or bacterial buildup inside the indoor unit. These odors often worsen when the system is running.

Black or Discolored Splotches on the Indoor Unit
Visible dark spots or discoloration on the wall-mounted unit—especially noticeable when lifting the AC cover—can indicate mold growth or heavy dirt buildup inside the system.

Reduced Cooling Performance
If your air conditioner is not cooling as effectively as before, it may be due to a dirty blower wheel or clogged coil. When left uncleaned, this buildup can also cause a persistent musty smell and reduced airflow.

Increased Respiratory or Allergy-Like Symptoms Indoors
Mold, bacteria, and airborne contaminants inside a dirty mini-split can circulate throughout your space, potentially triggering allergies, asthma symptoms, headaches, or respiratory irritation.

Water Leaking from the AC Unit
AC leakage is often a sign of a clogged drain line or excess moisture buildup inside the unit. This creates the perfect environment for mold growth and should be addressed promptly.

Consumers are often unaware that cleaning the Many consumers are unaware that cleaning the filters is only one part of properly maintaining a mini-split or ductless air conditioning system. While filter cleaning is considered basic maintenance, regular use requires a thorough cleaning of the entire indoor head unit, including the coils, blower wheel, and drainage components. To ensure proper performance, air quality, and longevity, the system must be professionally and correctly SplitCleaned.
