In the larger setting of Dubai property markets, 'chiller-free' apartments are those where the building management or landlord covers the cost of air conditioning, which is covered by the monthly rent.
This is a more thorough explanation:
In contrast to traditional apartments, where air conditioning expenses (also known as "chiller charges") are billed separately and paid by the renter as a portion of their utility bill, "chiller-free" rental arrangements do not charge tenants for air conditioning.
A central chiller mechanism is installed (typically on the building's roof) and linked to the main electricity meter in apartments without chillers. The renters only have to pay for their regular electricity, water and sewerage use (DEWA bill), and the landlord or property manager takes care of the cooling.
Tenants may benefit from this arrangement since it removes the need to monitor and pay for varying air conditioning expenses, which can change depending on usage and weather.
You may get a DEWA bill for electricity, water and sewerage in a flat without a chiller, but no separate invoice for air conditioning.
In certain places, especially freehold areas, tenants receive separate bills for demand and consumption charges, and cooling is managed by businesses like Palm Utilities, Empower, or Emicool. However, the tenant is not required to move the account into their name if the owner bears these costs.
