Split-Type AC Cleaning, Repair and Installation

Split-type units separate the indoor and outdoor components for quieter operation and are the most common residential choice in Hong Kong. Learn about cleaning prices (including the outdoor-unit add-on), repair, and installation.

When this service is suitable

Split-type air conditioners consist of an indoor evaporator and an outdoor compressor/condenser connected by refrigerant pipework. The indoor unit runs quietly; outdoor unit placement and ventilation are the main installation planning concerns. Cleaning follows a fixed price schedule; outdoor-unit cleaning is an optional add-on. Repair and installation are inspection-first, quote-after.

  • Indoor unit cleaning follows a published price schedule with multi-unit discounts
  • Outdoor-unit cleaning is an optional add-on, not included in the base clean
  • Repair and installation require an on-site assessment before a quote is given

Cleaning

Split-type cleaning covers the indoor unit: disassembling and washing the fan blades, filters and cover, deep-cleaning the cooling coil, and flushing the drain. A 90-day drip and leak follow-up is included. The outdoor condenser is not in the base clean; outdoor-unit cleaning is an optional add-on at an additional per-unit cost.

  • Disassemble and wash indoor fan blades, filters and cover
  • Deep clean indoor evaporator and cooling coil
  • High-pressure flush of the drain pipe and drain pan
  • Reassemble, test run, and 90-day drip and leak follow-up
  • Optional outdoor-unit cleaning available at an additional cost

Repair and Fault Inspection

Common split-type issues include weak cooling, indoor unit dripping, poor drainage and unusual noise. Repair is inspection-first, quote-after: the technician assesses on-site and explains the findings before any repair is agreed.

  • Weak cooling: check for dust blockage before assessing refrigerant and outdoor unit
  • Indoor unit dripping: assess drain pipe, installation angle or parts
  • Unusual noise: check indoor and outdoor unit operation
  • Low refrigerant: locate and fix the leak first, then top up
  • Repair only confirmed and quoted after on-site inspection

Installation and Removal

Split-type installation involves planning the outdoor unit location, refrigerant pipework routing and drainage. Installation is site-review-first: the technician reviews conditions before proposing a plan and quote.

  • Plan outdoor unit location (rooftop, exterior wall or AC platform)
  • Route refrigerant pipework; extra length beyond standard is charged separately
  • Ensure drain pipe maintains a continuous downward slope
  • Check building management rules on exterior modifications
  • Post-installation test run to confirm cooling and drainage

Price and quote factors

  • Outdoor-unit cleaning: base clean covers the indoor unit only; outdoor-unit cleaning is an add-on at extra per-unit cost
  • Pipework length: refrigerant pipework beyond the standard length is charged by the actual length
  • Repair scope: fault cause determines the work needed; a quote is only given after on-site inspection

Frequently asked questions

Does split-type cleaning always include the outdoor unit?

No. The base clean covers the indoor unit only. Outdoor-unit cleaning is an optional add-on; the additional cost is calculated per unit.

Can I top up the refrigerant myself if cooling is weak?

This is not recommended. Refrigerant circulates in a sealed system and does not deplete in normal use — if it is low, there is a leak that should be found and fixed first. Refrigerant handling requires specialist equipment; book a fault inspection instead.

What happens if the pipework is longer than standard?

Pipework length beyond the standard allowance is charged at the actual length. The technician will explain the required length and the additional cost during the site visit.
