Mini Split Deep Clean
Does the inside of your wall unit look like a science experiment? Is the blower wheel hairy?
A full pressure wash, coil cleaner treatment, blower wheel scrub, drain flush, and performance check — everything your system needs to run clean, cool, and efficient.

A dirty evaporator coil can reduce system efficiency by up to 30%, driving up your electric bill every month.
Buildup on the blower wheel reduces airflow enough to cost you 5°F or more of cooling capacity on the hottest days.
Mold and biofilm on the evaporator coil and blower wheel are the #1 cause of musty smells from mini splits.
If It Smells Musty, This Is Why
Mini splits don't have filters that catch everything. Over time, dust, mold, and biofilm build up on the evaporator coil and blower wheel — the two components that touch every cubic foot of air in your home. A standard filter rinse doesn't reach them.
Our deep clean uses a professional cleaning bag to contain the water, then pressure washes and treats the coil and blower wheel directly. It's the only way to actually remove the buildup — not just cover it up.
Recommended every 12–18 months in Arizona. Dust, heat, and monsoon humidity accelerate buildup faster than most climates.
Typical buildup on a mini split that hasn't been deep cleaned — this is circulating through your home's air
What We Do on Every Deep Clean
This isn't a filter rinse. Every deep clean covers all eight steps below — no shortcuts, no upsells.
Full Pressure Wash — Indoor & Outdoor Units
We bag the indoor wall unit with a professional cleaning cover and pressure wash the evaporator coil, blower wheel, and drain pan. The outdoor condenser coil gets a full rinse to restore airflow and heat exchange efficiency.
Coil Cleaner Treatment
Professional-grade foaming coil cleaner is applied to both the evaporator and condenser coils. It breaks down grease, biofilm, and oxidation that pressure alone can't remove — restoring the coil surface to near-factory condition.
Blower Wheel Deep Clean
The blower wheel is the most neglected part of any mini split. We clean every blade individually, removing the thick buildup of dust, mold, and debris that chokes airflow and circulates contaminants through your home.
Drain Pan & Drain Line Flush
We flush the condensate drain pan and drain line with a biocide treatment to eliminate mold, algae, and slime buildup — preventing drain clogs, water damage, and foul odors.
Filter Cleaning & Inspection
All filters are removed, cleaned, and inspected. We check for damage, proper fit, and airflow restriction — and advise on replacement if needed.
Electrical & Refrigerant Visual Inspection
While the unit is open, we visually inspect electrical connections, capacitors, and refrigerant line connections for signs of wear, corrosion, or early failure — catching problems before they become expensive repairs.
Airflow & Temperature Delta Check
After cleaning, we verify the system is performing correctly by measuring supply and return air temperatures. A properly cleaned unit should show a 15–20°F temperature split — we confirm yours is hitting that mark.
Mold & Odor Elimination
Dirty mini splits are a leading cause of musty odors and indoor air quality problems in Arizona homes. Our deep clean removes the mold and biofilm at the source — not just masking it.
