Service, cleaning, sanitising – three different jobs or the same thing at three prices?

Editorial guide · Updated 18 September 2026

In short Short answer: in practice, a correct service includes all three, because you cannot sanitise what you have not cleaned and cannot check what you have not opened. See current rates on the Prices page.

This page explains a situation in an editorial format. It is not an open discussion board or a verified customer review. Contact us on WhatsApp about your own appliance.

Situation discussed

I do not understand what differs. The units are Gree, 12,000 BTU, 3 years old, one in the living room, one in the children's room. See current rates on the Prices page.

What is really happening

The terms do mean something: 'service' = checking the condition (visual, drain, temperature, noise); 'cleaning' = physically removing dirt and biofilm from the evaporator, roller and pan; 'sanitising' = applying a disinfecting solution to surfaces that are already clean. The EPA principle is clear: mould must be physically removed, not just 'killed', and biocides on dirt have no demonstrated effect. See current rates on the Prices page.

Explanatory diagramFour services, different purposes
Four services, different purposes
  1. Inspection: assessing condition and symptoms.
  2. Service check: checks and measurements appropriate to the unit.
  3. Cleaning: removing deposits.
  4. Sanitising: suitable treatment of cleaned surfaces.

The actual scope is confirmed before the visit.

What the studies say
  • EPA principle: mould must be physically removed, not merely 'killed'; biocides are not recommended as routine practice. [US EPA, 2024]
  • EPA warns that the effectiveness of biocides sprayed into air systems has not been demonstrated and their health effects are uncertain. [US EPA, 2024]
  • Mould remains allergenic even when dead, so merely 'killing' it with a spray does not solve the problem – it must be physically removed. [US EPA, 2024]
  • Washing with alkaline detergent, brushing and high-pressure rinsing reduces fungi inside the unit by more than 99%. [Indoor Air, 2023]

What we do on site

  1. Inspection (the 'service'): evaporator, roller, pan, drain, connections visually, temperature split – on both units.
  2. Cleaning: sealed double waterproof cover, hose to the bucket, alkaline solution, adjustable pressure wash of the evaporator, roller, pan and hose, in place.
  3. Sanitising: the second solution on the clean surfaces, including pan and louvres; filters washed.
  4. Outdoor units in the yard: washed in place.
  5. Final test, bucket with clear water, photos. See current rates on the Prices page.

What you can do yourself

  • When you get a list, ask: 'does sanitising involve washing the evaporator with water or only spraying?' – the answer says it all.

What NOT to do

  • Do not buy 'sanitising' separately from cleaning; it is spray on dirt.
  • See current rates on the Prices page.

Prevention

Living room: once a year. Children's room: twice a year if used at night too.
