Ductless Mini-Split Deep Cleaning & Restoration

Ductless mini-split systems deliver high-efficiency year-round comfort. However, constant air recirculation creates breeding grounds for dust, pet dander, mold, and bacteria that lower indoor air quality and drive up utility costs.

Complete Teardown & Care

Beyond Standard Filter Rinsing

At O2 Clean Breathing Inc., our certified technicians perform meticulous internal component teardowns that standard maintenance misses.

Coil & Pan Sanitization

Blower Wheel Flushing

Efficiency & Protection

We thoroughly sanitize evaporator coils and drain pans using eco-friendly solutions to stop mold spores before they spread into your living spaces.

The blower wheel accumulates dense layers of dust that restrict airflow. Our custom pressure-washing process completely flushes out hidden contaminants.

Deep cleaning extends equipment lifespan, lowers energy bills, and protects your family's health by eliminating airborne allergens at the source.

• Questions & Answers

Mini-Split Cleaning FAQs

How often should mini-splits be cleaned?

Why isn't washing reusable filters enough?

We recommend a professional deep clean once a year for residential units, or every 6 months for homes with pets, high humidity, or heavy year-round heating and cooling usage.

Reusable mesh filters catch large dust particles, but micro-spores, bacteria, and moisture pass directly onto internal blower wheels and coils where toxic mold thrives out of reach.

What are signs my system needs deep cleaning?

How long does a service appointment take?

Musty odors when turning on the unit, visible black specks blowing from the louvers, reduced airflow, or unexplainable increases in monthly electric bills are clear indicators.

A thorough deep clean takes approximately 60 to 90 minutes per head unit. Our bib system prevents water or debris from touching your walls, furniture, or flooring.
