Keep your ductless AC running clean, cold, and efficient. Our technicians provide thorough mini split deep cleaning for all major brands — removing mold, dust, and buildup from coils, blower wheels, filters, and drain lines.
Ductless mini split systems are one of the most popular heating and cooling solutions on Nantucket — and for good reason. They’re efficient, quiet, and perfect for island homes that don’t have traditional ductwork. But like any HVAC system, mini splits need regular maintenance to perform their best.
Over time, dust, pollen, pet dander, and moisture accumulate inside your mini split’s indoor unit. The evaporator coils get coated, the blower wheel collects debris, the filters clog, and the drain line can develop blockages. In Nantucket’s humid coastal environment, this moisture creates the perfect conditions for mini split mold — a hidden health hazard that can circulate spores throughout your home every time the unit runs.
Our professional mini split cleaning service goes far beyond what a homeowner can do with a basic filter rinse. We perform a comprehensive mini split deep cleaning of every component inside your indoor unit — restoring airflow, eliminating odors, improving efficiency, and protecting your indoor air quality.
1
Pre-Cleaning Inspection
We inspect your mini split unit, check for visible mold or excessive buildup, test airflow, and note any issues with the system before we begin. We’ll also lay down protective coverings to keep your walls and floors clean during service.
2
Mini Split Filter Cleaning
We remove, wash, and sanitize the air filters. Clogged filters are the most common cause of reduced cooling performance and increased energy consumption. Regular mini split filter cleaning alone can make a noticeable difference.
3
Evaporator Coil Cleaning
The evaporator coils are where the real buildup lives. We apply professional-grade coil cleaner and flush the coils thoroughly, removing layers of dust, grime, and mold that restrict airflow and reduce cooling capacity. This mini split coil cleaning is the most critical step in the process.
4
Blower Wheel Deep Clean
The blower wheel (fan) is one of the dirtiest components inside a mini split. Dust and mold cling to every blade, reducing airflow and creating musty odors. Our mini split blower wheel cleaning removes all buildup so air moves freely and cleanly.
5
Drain Line Clearing
A clogged condensate drain line can cause water leaks, mold growth, and even unit shutdowns. We clear the mini split drain line of all algae, slime, and debris to ensure proper drainage and prevent water damage.
6
Sanitize & Reassemble
After cleaning every component, we apply an antimicrobial treatment to inhibit future mold growth, reassemble the unit, and verify that the system is running properly with improved airflow and cooling performance.
Remove mold, dust, and allergens that circulate through your home every time the unit runs. Breathe cleaner, healthier air.
Dirty coils and clogged filters force your mini split to work harder. Clean components mean lower energy bills and faster cooling.
Regular ductless mini split maintenance prevents premature wear on compressors, fans, and electrical components — saving you from costly replacements.
That musty smell when your mini split kicks on? That's mold and bacteria on the coils and blower wheel. A deep cleaning eliminates it completely.
We clean all ductless mini split brands commonly found on Nantucket, including:
Mitsubishi
Fujitsu
Daikin
LG
Samsung
Carrier
Whether you have a single wall-mounted unit or a multi-zone system with units throughout the house, we clean them all. Cleaning a Mitsubishi mini split is our most common request, but every brand gets the same thorough service.
We recommend a professional mini split deep cleaning at least once per year — ideally in the spring before cooling season begins. If your unit runs year-round for both heating and cooling, or if you notice reduced performance or odors, twice-yearly cleaning may be appropriate. Basic filter cleaning should be done monthly by the homeowner between professional services.
Mini split cleaning cost depends on the number of indoor units and their condition. We offer per-unit pricing with discounts for multi-unit cleanings. Call us at (508) 901-2939 or book online for a quote. Most homeowners find that the energy savings and extended equipment life more than pay for the service.
Yes. Most of the buildup inside a mini split is invisible from the outside. Mold grows on the backside of the coils and deep inside the blower wheel where you can’t see it. By the time you notice reduced performance or a musty smell, the contamination is often significant. Annual cleaning prevents problems before they start and keeps your indoor air quality high.
Absolutely. Many Nantucket homes have multi-zone ductless systems with 2, 3, or even 5+ indoor units connected to one outdoor compressor. We clean each indoor head unit individually and offer volume pricing for homes with multiple units. The outdoor condenser unit can also be cleaned as part of the service.
Most likely, yes. A musty or sour smell when your mini split runs is the most common sign of mold growth inside the unit. Nantucket’s humid coastal climate makes mini split mold especially common. A professional deep cleaning removes the mold, and our antimicrobial treatment helps prevent it from returning quickly. Don’t ignore the smell — mold spores circulating through your home can affect respiratory health.
