There are three completely different cooling arrangements in Dubai apartments. Most brokers use "chiller-free" to mean at least two of them. Getting this wrong can cost you thousands of dirhams a year.
Every Dubai apartment has a DEWA bill — electricity and water, always. What differs is how the cooling cost is handled on top of that. Three completely different arrangements. One misleading term used for all of them.
We have seen real bills from all three types. Here is exactly what each one means, what it will actually cost you, and the three questions to ask before you sign any lease.
A broker says "chiller-free." This can mean the building has DEWA-managed cooling (you still pay for cooling, just through your DEWA bill) or it can mean true chiller-free (landlord pays all cooling). These are completely different financially. Always ask which one specifically.
Based on real bill data and practical experience across multiple Dubai properties, here is how the three cooling arrangements rank for residents:
In all three types you will receive a DEWA bill every month for electricity and water. What changes is whether cooling is a separate bill, embedded in DEWA, or paid by the landlord.
Every apartment has a DEWA bill. The question is how much cooling adds on top. Here is a realistic annual cooling cost estimate for a 2-bedroom unit under each arrangement.
| Cooling cost | AED 0 |
| Fixed floor | None |
| DEWA (normal) | AED 4,000–6,000/yr |
| Chiller deposit | None |
| Rent premium | +10–15% |
| Best for | Heavy AC users |
| Summer DEWA | AED 700–1,200/mo |
| Winter DEWA | AED 200–400/mo |
| Fixed floor | None |
| Chiller deposit | None |
| Rent premium | None |
| Best for | Moderate users |
| Fixed floor/mo | AED 220–420 |
| Peak summer | AED 600–1,100/mo |
| Annual total | AED 6,000–12,000 |
| Chiller deposit | AED 2,000–3,500+ |
| Rent premium | None |
| Best for | Light AC users |
True chiller-free is best for heavy AC users, families, and year-round residents. The rent premium is usually recovered in 6–12 months of cooling cost savings. Always confirm in writing — a verbal assurance means nothing.
DEWA building is excellent for most residents — no fixed floor, no deposit, professionally maintained, usage-based billing. The summer DEWA bills will be higher but you are only paying for what you use.
District cooling works for light AC users or those who travel frequently — but watch the fixed capacity floor. Even with no AC usage in winter you still pay AED 220–420/month minimum. And the upfront deposit adds to your move-in costs.
Many brokers use "chiller-free" to mean "no separate chiller company bill" — which is technically true for both Type 1 and Type 2. From the broker's perspective, both mean "no Empower/Aquacool bill" — which sounds the same but is financially very different.
A DEWA building resident in a 2BR can easily pay AED 6,000–8,000/year in cooling through their DEWA bill. That is not free. Never accept "chiller-free" at face value — ask specifically which of the three arrangements the building uses.
Compare apartments on annual rent plus estimated annual cooling cost plus chiller deposit amortised over your tenancy. A district cooling apartment with a lower headline rent can easily cost AED 5,000–8,000 more per year than a true chiller-free apartment once cooling bills are included. Run the numbers before you decide.
