What Does A Ductless AC Cleaning include?
Our comprehensive AC tune-ups include a multi-point inspection of your entire system. Our highly trained and experienced technicians will look for common issues and address any problems they may find.
Our ductless AC cleaning service includes:
- Check And Clean/Replace The Air Filter
- Clean Any Secondary Filters
- Inspect Evaporator Coils And Clean As Needed
- Balance Fan Wheel And Blower Assembly, If Necessary

Our technicians can service all makes and models, including those by Fujitsu, Samsung, Daikin, Mitsubishi, Trane, Lennox, and Carrier. Since 2001, working on ductless systems, we understand what goes in to properly maintaining these types of systems.
A professional mini split cleaning removes the dust, mold, and biofilm that build up on the evaporator coil, blower wheel, and drain pan, which no filter rinse can reach. Dr. Ductless has cleaned and serviced ductless systems across Los Angeles and the South Bay since 2001, and a standard cleaning of a single indoor head takes our technician 60–90 minutes in your home.
What you need to know
- A standard cleaning is $199 for the first indoor head and $59.99 for each additional head. A three-zone system is $318.98.
- Clean the filters yourself monthly. Have the coil, blower wheel, and drain line professionally cleaned once a year, or twice if you are within a mile of the coast or run the system year-round for heat.
- A musty smell when the unit starts, water dripping from the indoor head, or weaker airflow on the same fan setting are the three signs it is overdue.
- We service every major ductless brand and are an Elite Diamond Contractor for Mitsubishi Electric.
- Cleaning is included in our maintenance plans, which also cover priority scheduling during summer heat waves.
What a professional mini split cleaning costs in Los Angeles
A standard mini split cleaning from Dr. Ductless is $199 for the first indoor head and $59.99 for each additional head. The price depends on three things: how many indoor heads you have, whether the blower wheel needs to be pulled for a deep clean, and how long it has been since the last service. Systems that have never been cleaned almost always need the deep clean.
| Service | What's included | Time on site | Price |
|---|---|---|---|
| Standard cleaning, first indoor head | Filters, coil surface, drain pan and line flush, outdoor coil rinse, operational test | 60–90 min | $199 |
| Each additional indoor head | Same scope per indoor unit, same visit | +30–45 min | $59.99 |
| Three-zone system (example) | All three heads cleaned in one visit | About 2½ hours | $318.98 |
| Deep clean | Everything above plus blower wheel removal and wash, coil foam treatment, antimicrobial rinse | 2–3 hours | Quoted per job — typically around $1,300 for three zones |
| Diagnostic visit (if something is broken) | Full inspection, error-code readout, written repair quote | — | $189, applied toward the repair |
| Maintenance plan | Annual cleaning, priority scheduling, repair discount | — | See plans |
Prices are for residential systems in our Los Angeles service area and are current as of September 2026. Commercial systems and rooftop or high-ceiling installations are quoted after a site visit.
How often should a mini split be cleaned?
Once a year for most Los Angeles homes, and twice a year if the home is near the coast, the system runs for heat in winter, or anyone in the house has asthma or allergies. Salt air in Redondo Beach, Manhattan Beach, and Hermosa Beach accelerates corrosion on the outdoor coil, and year-round use means the indoor coil never gets a dry season to shed moisture, which is when mold takes hold.
Rule of thumb: if the unit has run more than about 1,500 hours since the last cleaning, it is due. A bedroom head running eight hours a night reaches that in six months.
Mitsubishi Electric units with Dual Barrier Coating on the fan and coil resist buildup noticeably longer than uncoated units, which is one reason we specify them for beach-city homes. They still need the drain line and pan serviced on the same schedule.
What you can clean yourself and what you should not
The mesh filters behind the front panel are designed to be removed and rinsed by the homeowner every two to four weeks in summer. Everything behind them is where the professional work starts.
| Component | DIY? | Why |
|---|---|---|
| Mesh pre-filters | Yes, monthly | Pull out, rinse, air dry, reinstall |
| Front panel and louvers | Yes | Wipe with a damp cloth while the unit is off |
| Evaporator coil | No | Fins bend easily; requires a no-rinse coil cleaner and a bib to protect the wall and electronics |
| Blower wheel | No | Must be removed to clean; this is where the musty smell lives |
| Drain pan and condensate line | No | Biofilm clogs cause the dripping most homeowners call about |
| Outdoor unit coil | Light rinse only | Never pressure-wash; fins collapse and capacity drops |
Do not use spray-can coil cleaner on a running unit. Most aerosol cleaners sold for mini splits are not safe for the control board behind the coil, and overspray into the electronics is the most common cause of the “it worked before I cleaned it” repair calls we get in July.
How our technicians clean a ductless system
Every cleaning follows the same order, so you know exactly what you are paying for:
- Operational test and photos before work — airflow, supply temperature, and any error codes are recorded.
- Filters and panel — pre-filters and any secondary filters are removed, washed, and dried.
- Coil and blower — a cleaning bib is fitted under the head, then the evaporator coil and blower wheel are treated with a no-rinse foaming cleaner and flushed. Deep cleans pull the wheel.
- Drain pan and line — the pan is cleaned and the condensate line is flushed or vacuumed clear, including the lift pump if one is installed.
- Outdoor unit — coil rinsed from the inside out, debris cleared, line set insulation inspected.
- Test after work — supply temperature and airflow re-measured, remote and wall controller functions checked, and you get the before-and-after readings.
Frequently asked questions
How much does it cost to get a mini split cleaned?
A standard cleaning is $199 for the first indoor head and $59.99 for each additional head, so a three-zone system is $318.98. A deep clean with blower-wheel removal is quoted per job and typically runs around $1,300 for three zones. If the unit is leaking or not cooling, a $189 diagnostic visit comes first and is applied toward the repair.
Do mini splits need to be professionally cleaned?
Yes. Homeowners can and should rinse the mesh filters, but the evaporator coil, blower wheel, and drain pan sit behind the filters and accumulate mold and biofilm that only a proper coil cleaner, bib, and flush can remove. A unit that has never been professionally cleaned is also the most common source of the musty “dirty sock” smell on startup.
How often should I get my mini split cleaned?
Once a year in most Los Angeles homes. Twice a year for coastal homes exposed to salt air, systems used for heating in winter, and households with allergies or asthma.
Can I clean my mini split myself?
You can clean the filters and wipe the front panel. Cleaning the coil and blower wheel yourself risks bent fins, water in the control board, and a voided manufacturer warranty. Mitsubishi Electric, Daikin, and Fujitsu all require professional service to keep their parts warranties in force.
What are the signs a mini split needs cleaning?
A musty or sour smell when the unit starts, water dripping from the indoor head or down the wall, weaker airflow at the same fan speed, black specks blowing out of the louvers, and higher electric bills with no change in use.
Do you clean brands other than Mitsubishi?
Yes. We service Mitsubishi Electric, Daikin, Fujitsu General, and the other major ductless brands. If you are not sure whether we work on your unit, call with the model number and we will tell you on the spot.
