Why choose central air conditioning?

Central packaged air conditioning (Package Unit) is the ideal solution for large commercial projects that require continuous operation and stable, uninterrupted cooling.

Central air conditioning systems are ideal for malls, hospitals, and administrative buildings thanks to their ability to serve multiple spaces using a single outdoor unit.

Heavy-duty central air conditioning systems are designed to handle high loads and operate efficiently in the hot climate of Saudi Arabia.

The success of a central air conditioning system depends on proper engineering design and execution more than just the type of unit used.

Central AC engineering design

Designing duct routes and air distribution points according to precise engineering standards.

First-Fix Preparation

Preparing the concrete bases and openings, thermostat locations, and wall penetrations.

Installation stage

Installing the Package Unit on the rooftop, then connecting it to the main duct network (Supply / Return).

Testing and Handover

Operating the hvac for a period of (72 hours) to ensure the efficiency of cooling, ducting, air flow strength and distribution, then hand over the warranty

The performance of a central AC system depends on precise engineering design and high-quality installation, not only on the cooling unit’s power or brand.

FAQs about Central AC Systems

How does central air conditioning help reduce operating costs for my project?

Modern package units come with high energy efficiency (EER). In addition, their maintenance is easier and faster since they are single, integrated units, which reduces the time and cost of periodic maintenance contracts compared to maintaining dozens of separate units.

Can a central AC system be integrated with a Building Management System (BMS)?

Yes, most of the modern central air conditioning units we provide can be integrated with BMS systems for centralized control and remote monitoring, which is a preferred option for administrative buildings and shopping malls.

What is the warranty period for package units, and do you offer annual maintenance contracts?

Most global brands (such as Carrier and York) offer a compressor warranty of up to 5 or 7 years. At United HVAC, we also provide annual preventive maintenance contracts for projects to ensure continuous, efficient operation of the units and to prevent any unexpected breakdowns that could impact your business operations.

I have an old building with a deteriorated central AC system—can it be replaced with a new one without disrupting operations?

Yes, we have a specialized team for replacement projects. We dismantle old units and install new ones using cranes within a short timeframe (often over the weekend) to ensure business operations are not disrupted, while connecting them to the existing duct network after inspection and cleaning.

What are the specifications of the ductwork used, and how do you ensure there is no air leakage?

We use high-quality galvanized steel sheet (G90) from SABIC, compliant with international standards (SMACNA). All joints are precisely sealed and tested to ensure zero leakage, guaranteeing that cooling reaches the space efficiently with no loss.

My business is a restaurant / central kitchen and requires strong ventilation—Is central air conditioning sufficient?

For kitchens and restaurants, we design a hybrid system: central (package) air conditioning for the dining area to ensure customer comfort, along with a dedicated fresh air and exhaust ventilation system for the kitchen to remove heat and odors. We also perform air balancing to prevent cooking smells from transferring to the dining area.

Can the thermostat be installed only in the manager’s office or the control room?

Yes. To prevent temperature tampering by staff or visitors, we can extend control points and install the thermostat in secure central locations or within dedicated management control rooms.

Can the temperature of each room be controlled separately?

In the standard configuration, a package unit operates on a “single-zone” system, controlling the entire open area (such as a showroom) through a single thermostat. However, for offices and enclosed rooms, the system can be upgraded by adding (VAV – Variable Air Volume) technology. This technology relies on smart dampers inside the ductwork, allowing fully independent temperature control for each room or office, providing comfort and privacy for every employee.

What is your installation and project completion timeline?

We understand that ‘time is money’ in commercial projects. We have dedicated installation teams and our own duct fabrication facility to ensure timely supply and installation in line with the project schedule, without any delays.

Does central air conditioning affect the leasable area of the building?

On the contrary, central air conditioning is the best investment option, as it does not occupy any internal space (no wall-mounted or floor-standing units), giving you complete freedom to utilize the area for shelving or interior décor.
