Mini-splits collect dust, mold, and bacteria inside the blower wheel and coil — where you can't see it. Without an annual deep clean, that buildup blows straight into your living space.

All deep-clean tasks complete
Mini-splits collect dust and mold faster than ducted systems. Annual cleaning is essential.
Mini-splits have no ductwork to filter air. Everything collects inside the indoor unit — right where you breathe.
Every mini-split deep clean follows a thorough 8-point process. Nothing gets missed.
Filters removed, washed, and reinstalled. Damaged filters replaced. Dirty filters are the first thing that chokes airflow.
The blower wheel is where mold hides. We disassemble and hand-wash it to remove every trace of buildup.
Coil cleaned with professional-grade solution. Removes grime that blocks heat transfer and breeds bacteria.
Drain pan cleared and flushed. A clogged condensate line causes water leaks, mold growth, and system shutdowns.
Condenser coil rinsed and cleared of debris. A dirty outdoor unit forces the compressor to overwork and overheat.
All wiring inspected and tightened. Loose connections cause arc faults, tripped breakers, and board damage.
Pressures measured against manufacturer spec. Low refrigerant means a leak — and a compressor that won't last.
Every interior surface inspected for biological growth. If found, treated and sanitized before reassembly.
"They pulled out the blower wheel and it was covered in black mold. I had no idea. After the deep clean, the air smells completely different — fresh and clean. Should have done this years ago."
"We have three Mitsubishi mini-splits. Next Phase cleaned all three in one visit. Thorough, on time, and they showed us before-and-after photos. The difference was shocking."
"Our Daikin unit was blowing warm air and had a musty smell. The tech found the coil was completely caked with dust. After the deep clean, it's cooling like the day we installed it."
"We've had annual maintenance for four years now. Our Fujitsu units are seven years old and still run perfectly. The technicians are always professional and explain what they're doing."
"The condensate drain was completely blocked and starting to leak. They caught it during the tune-up before it damaged the wall. That alone made the service worth it."

Mini-splits don't have ductwork, so dust, pollen, and moisture collect directly on the blower wheel and evaporator coil inside the indoor unit. A filter change alone doesn't reach these components. Without a full disassembly and wash, mold and bacteria build up and blow into your living space.
Very common, especially in the Pacific Northwest. The combination of moisture from the cooling cycle and organic dust creates ideal conditions for mold growth inside the blower wheel and drain pan. Most homeowners don't notice until they smell it or see dark residue on the vanes.
Once a year is the standard recommendation. If you run your mini-split year-round for both heating and cooling, or if anyone in your household has allergies or asthma, twice a year is ideal. Between professional cleanings, rinse your filters monthly.
You can wash the filters, but the blower wheel and evaporator coil require disassembly, specialized cleaning solutions, and a bib kit to contain runoff. Incorrect cleaning can damage the fins, push mold deeper, or cause electrical issues. Professional service is strongly recommended.
Most manufacturers — including Mitsubishi, Daikin, and Fujitsu — require proof of annual professional maintenance to honor warranty claims. If your compressor fails and you have no service records, the manufacturer will likely deny the claim.
