Liwan is a dense cluster of low-rise apartment buildings in Dubailand, heavily tenanted and mostly on split systems. That is the starting point for how we scope and price work here.
Most properties here are apartments inside a managed tower, so the cooling arrives as chilled water from the building and the unit in your ceiling is a fan coil rather than a system of your own. There is no outdoor condenser to service, the landlord owns everything upstream of your riser valve, and access usually means a booked service lift and a work permit from building management.
Plant in a tower is shared, which makes the boundary the important question: the building owns the chillers, pumps and risers, and the tenant owns everything past the valve. We document which side a fault sits on before work starts, because that single piece of evidence settles more disputes between tenant and building management than any amount of argument.
None of that is guesswork on the day. We survey the property in Liwan first, tell you what we actually found, and fix the price in writing before any work starts.
Tell us about the property in Liwan and we confirm a fixed written price after inspection. No charge to quote.
