Compare the work scope before booking
These providers publish different servicing, cleaning, repair and installation routes. Ask what each quote includes for your unit type and number of units. Compare taxes, transport and access charges, contract terms, and whether any additional work needs your approval.
Which option matches your enquiry?
Compare the same unit count, visit count and work scope. 338 publishes one-time servicing from $65 for one unit and a separate quarterly four-visit contract table. Billy publishes one-unit servicing at $50 and three units at $70 before GST. Confirm transport and any extra work rather than inferring inclusions.
Letscool publishes $30 plus $20 transport for one unit, $50 for two, $75 for three and $100 for four. It says transport is free for two or more units. The page labels offers as limited-time and subject to terms; confirm eligibility and GST treatment before booking.
Luce’s $16.35 including GST is a contract rate per unit in the 11-or-more-unit tier. It is not a one-off one-unit price. Ask for the total for your own unit count and contract frequency. A low advertised unit rate cannot be compared with a single visit until these conditions match.

Is Luce’s $16.35 rate a one-off one-unit price?
