How often should tenanted unit aircons be serviced?

Whats the norm - quarterly with receipts to prove?

Hi there,

The norm for aircon servicing is quarterly (with receipts), but there are somewhat landlords who are ok with 4month intervals as well.
Usually better to ask owner if they have a contract or regular service company, and the tenant can just continue that. Always ask for prior receipts as well.
Getting a new service person may end up in disputes where the landlord may not be happy with the quality.

Hope this helps.
