Cleaning Multiple AC Units: How Multi-Unit Pricing Works

If a home or office has several window or split-type units, multi-unit cleaning follows a decreasing per-unit schedule. Arranging them together saves time and reduces visits.

When this service is suitable

Multi-unit cleaning is a common arrangement for homes and small to medium commercial spaces. The more units cleaned together, the lower the average per-unit price. This page explains the pricing structure, what is included and the practical considerations for arranging multiple units. Window and split-type units can be combined in a single count for the base clean.

  • More units cleaned together means a lower average per-unit price
  • Window and split-type units can be combined for the multi-unit base price
  • Arranging all units in one visit reduces the need for multiple bookings

Arranging a Multi-Unit Clean

Confirming the unit types, quantity and any add-ons before booking makes the visit smoother.

  • List all unit types (window or split) and the total count
  • Decide whether to add outdoor-unit cleaning or steam for any units
  • Large window units over 18,000 BTU (2.5 HP or more) carry a per-unit surcharge
  • Confirm all units have working power for the post-clean test

What Each Unit's Clean Covers

Each unit receives the full base clean; add-ons are selected per unit.

  • Pre-clean power-on test for each unit
  • Removal and washing of filters, fan blades and covers
  • Deep cleaning of the cooling coil and clearing of the drain pipe
  • Reassembly and post-clean test for each unit
  • Tidy-up of all work areas

If a Fault Is Found in Any Unit

Cleaning and repair are separate services; any issues are reported after cleaning.

  • Faults found in any unit during cleaning are reported honestly after completion
  • Repair is a separate inspection-first, quote-after service
  • Removal or installation of any unit is a separately quoted service
  • Cleaning includes a 90-day drip and leak follow-up (covering issues caused by the cleaning only)

Price and quote factors

  • Number of units: the price follows a published decreasing per-unit schedule
  • Unit type: large window units over 18,000 BTU carry a per-unit surcharge
  • Add-ons: Kärcher steam and outdoor-unit cleaning are optional and priced separately

Frequently asked questions

Can window and split-type units be combined for the multi-unit price?

Yes. The base clean is calculated on the total unit count. Large window units or optional outdoor-unit cleaning are added on top of that.

How long does a multi-unit clean take?

Cleaning time per unit depends on the type and level of build-up. Provide the total unit count when booking so the technician can schedule sufficient time.

Can cassette or ducted units be included in the same visit?

Ceiling cassette and ducted units have separate pricing and cleaning arrangements from window and split-type units. Check the relevant service pages or mention the unit types when booking.
