Start a Mini-Split and Portable AC Deep Cleaning Service

1. 1

   Learn the wash procedure properly

   Power off and verify, remove the shell and filters, bag the head with a bib that drains into a bucket, protect the electronics, apply the correct cleaner to the coil and blower wheel, rinse, flush and vacuum the condensate line, clean the shell and filters, reassemble, and test. Practice on a used head bought secondhand until the sequence is muscle memory.

2. 2

   Draw the line at refrigerant work

   Cleaning does not require opening the sealed refrigerant circuit, and you should not open one. Recovering or charging refrigerant requires an EPA Section 608 certified technician, and some states regulate HVAC work under a contractor license. Advertise cleaning and maintenance only, refer repairs to a licensed partner, and get a referral relationship in exchange.

3. 3

   Price per head with an additional-head discount

   The setup and drop cloths take as long as the wash. Quote a first-head price that reflects a real two-hour job and a lower price for each additional head at the same address; multi-head homes and short-term rentals are where the day becomes profitable.

4. 4

   Sell the smell, then show the water

   Customers call because of an odor. Photograph the coil and blower wheel before, and photograph the bucket water after. That contrast closes the neighbors, the property manager, and next season's repeat with no argument about price.

5. 5

   Target the addresses with the most heads

   Short-term rental hosts, small offices, dental and salon suites, converted garages and ADUs, condo buildings that went ductless, and homes with additions. Property managers and cleaning companies serving rentals are the best partners, because a musty unit generates guest complaints they already dread.

6. 6

   Build a seasonal recall and a maintenance plan

   Sell an annual or twice-yearly plan at a modest discount, scheduled before cooling season and after heavy use. Recurring bookings smooth the calendar and turn a summer trade into a year-round route, especially in climates where these units also heat.
