Frequently asked questions
Chemical wash or chemical overhaul?
A chemical overhaul goes further: the unit is dismantled and washed off the wall. The two are priced separately.
What does a chemical wash cost?
A chemical wash is usually priced per unit, and the price depends on the type of unit and the provider. Ask for a total across all your units and what the visit covers.
Is a chemical wash covered by my warranty?
Daikin lists general servicing of the air-conditioner among what its warranty excludes, so a chemical wash is your cost.
