Frequently Asked Questions
Air-cooled chillers reject heat through ambient air using condenser fans, making them ideal for rooftop and outdoor installations without requiring a cooling tower or water supply. Water-cooled chillers use a cooling tower and condenser water circuit to reject heat, offering higher efficiency for large-capacity applications. Air-cooled chillers are generally easier to install and maintain, and are the most widely used chiller type in the UAE’s commercial and industrial sector
We recommend monthly condenser coil inspection and cleaning, quarterly refrigerant pressure checks and oil system verification, and a comprehensive annual service covering full coil cleaning, motor testing, electrical inspection, sensor calibration, and performance verification. In the UAE’s dusty environment, condenser coil cleaning may be required more frequently — monthly for units in high-dust locations.
Common signs include reduced cooling output, higher than normal chilled water supply temperature, elevated compressor current draw, unusual noises or vibration, frequent alarm activations, visible refrigerant oil staining around joints or coil headers, sight glass showing bubbles during operation, and higher than expected energy consumption. If you notice any of these symptoms, contact Best Air for a diagnostic assessment before the issue escalates.
A Best Air AMC includes scheduled monthly, quarterly, and annual preventive maintenance visits; condenser coil cleaning; refrigerant circuit checks; oil system inspection; electrical panel servicing; sensor calibration; performance testing; emergency callout response; and detailed maintenance reports after each visit. The full scope is defined in the contract schedule, providing complete budget certainty for your chiller maintenance expenditure.
Under a structured preventive maintenance programme, a well-maintained air-cooled chiller can deliver 15 to 20 years of reliable service. Key factors that extend chiller life include regular condenser coil cleaning, correct refrigerant charge maintenance, timely compressor and oil system servicing, and early diagnosis and repair of developing faults before they progress to major failures.
Yes. Best Air maintains 24/7 emergency response capability across Al Ain, Ajman, and Abu Dhabi. Our engineers are equipped with electronic leak detectors, refrigeration manifold gauges, electrical diagnostic instruments, and on-vehicle replacement parts — including oil filters, filter driers, contactor assemblies, thermistors, transducers, EXV components, and CPM boards — to enable immediate corrective action without awaiting procurement lead times.
