If you notice a musty or “dirty sock” smell when your ductless mini-split is running, it’s a clear sign of mold spores or bacterial growth on the evaporator coils. This is a common issue in Maine’s humid summers. A professional sanitization from Moran Heat Pump Cleaning will eliminate these odors at the source and improve your indoor air quality (IAQ).

Why Mold Grows in Heat Pumps

The dark, damp environment inside your indoor unit is the perfect breeding ground for mold. Standard filter cleaning isn’t enough to reach the deep-seated growth on the blower wheel and coils. Our deep cleaning process uses specialized tools to ensure every component is sanitized, preventing respiratory issues and allergies.
