Type of air cond servicing for rental

[yh2511]

Hi,

I rental a whole unit and recently handover the unit back to owner and we did the aircond service.

However, owner insist we must do chemical wash (which he says about 400-500 for 3 units). The chemical wash and general service we did is not sufficient.

Is this common or what can i do about this? Appreciate everyone's advices.

Thanks and happy new year.

Does your rental agreement stipulate that the required A/C maintenance must include a chemical wash?
Does it have any other wording suggesting any criteria about the A/C servicing done?

Unless there is a high amount of dust in the air or if there is mould growing, a chemical wash is usually unnecessary & a waste of money, especially if you have kept the filter screen clean.
