Emergency Breakdown Services
Best Air maintains emergency response capability across Al Ain, Abu Dhabi, and Ajman, deploying certified HVAC engineers equipped with refrigeration manifold gauges, electronic leak detection instruments, clamp-on current meters, insulation resistance testers, and electrical diagnostic tools.
Engineers carry on-vehicle inventory of high-demand replacement components — including compressor contactors, overload relays, time delay relays, high and low pressure switches, fan belts, capacitors, thermostat assemblies, and filter drier cores — enabling immediate corrective action without awaiting component procurement. Our emergency response team is trained to rapidly diagnose and resolve the following high-impact RTU fault conditions:
Following emergency restoration of unit operation, Best Air provides a formal incident report within 24 hours covering root cause analysis, corrective actions undertaken, measured post-repair operating parameters, and preventive recommendations to reduce recurrence probability.
Annual Maintenance Contracts (AMC)
Best Air Conditioning Works & Maintenance offers structured Annual Maintenance Contracts for packaged rooftop unit installations, providing facility operators with a planned, budget-certain approach to RTU asset management. Our AMC programmes are aligned with SKM M-S Series and equivalent manufacturer service requirements, adapted to the UAE’s demanding operating environment where condenser coil fouling, belt degradation, and refrigerant circuit stress accumulate at rates significantly above temperate-climate benchmarks.
Clients operating under a Best Air RTU AMC benefit from reduced energy consumption through sustained coil cleanliness and optimal refrigerant charge; extended equipment lifespan through early detection of belt wear, bearing degradation, compressor current deviation, and refrigerant loss before they progress to failure; minimised unplanned downtime through proactive fault identification; budget certainty through a fixed annual contract value; and documented maintenance records supporting regulatory and insurance compliance.
Why Best Air Services for Your Rooftop Package Unit?

Certified Professionals
Our technicians are trained and certified in current HVAC technology, manufacturer service procedures, and UAE HSE requirements, ensuring every service meets the highest industry standards.
Quality Assurance
We use genuine OEM and approved equivalent replacement parts, structured inspection protocols, and documented commissioning procedures on every job — with detailed service reports provided after each visit.
Energy Efficiency
Our maintenance program sustain condenser coil cleanliness, correct refrigerant charge, proper belt tension, and accurate control calibration, the four factors that most directly reduce rooftop unit energy consumption and operating cost.
Industries We Cater to
Commercial Property
Office buildings, malls, and mixed-use facilities rely on rooftop units for consistent, energy-efficient comfort in high-footfall environments. Best Air ensures uninterrupted operation during peak commercial hours.
Healthcare Facilities
Hospitals, medical clinics, and care centres require precise temperature control and reliable air quality for patient safety and medical equipment performance — environments where HVAC failure is not an option.
Colleges and Universities
Educational campuses require quiet, reliable cooling that supports focused learning environments without disruption. Our structured AMC program keep rooftop units operating through peak academic periods.
Industrial and Manufacturing
Heavy-duty cooling loads in factories and warehouses demand rooftop units that are robustly maintained against UAE dust loading, high ambient temperatures, and sustained full-load operation. Our industrial RTU programmes are designed for exactly these conditions
Retail and Food Service
Supermarkets, restaurant chains, and food processing facilities must maintain consistent indoor temperatures for customer comfort and product integrity. Best Air serves clients including Al Ain Dairy, Al Ain Poultry, and International Royal Bakery.
Entertainment and Cultural Facilities
Theatres, entertainment venues, and cultural centres experience highly variable occupancy loads throughout the day. Our rooftop unit maintenance programmes ensure reliable performance across all occupancy conditions.
Specialized Facilities
Data centres, telecommunication facilities, and research laboratories requiring high-precision, continuous temperature control are served with dedicated AMC programmes and priority emergency response.

Frequently Asked Questions
A rooftop package unit is an all-in-one system of heat, cooling, and air handling confined to one unit on a building’s roof. It is meant for commercial and industrial applications.
A well-maintained rooftop package unit lasts 15-20 years. However, its efficiency may decline later, making replacement more economical.
After proper rooftop package unit installation, we recommend quarterly service visits, with a more detailed service visit before the height of the cooling season. That way, you are ensured superior performance and avoid any unscheduled breakdowns.
The most common indicators include:
- Abnormal noises or vibrations
- Cooling or heating problems
- Increased energy bills
- Poor indoor air quality
- Increased system cycling
Yes, we can upgrade existing units with today’s controls, variable speed drives, and other efficiency-enhancing components. We will evaluate your existing system and give you some budget-friendly upgrade options.
