HVAC installation in Al Majaz: local context
Al Majaz surrounds Khalid Lagoon and Al Majaz Waterfront in central Sharjah, a district of high-rise residential towers, hotels, offices and retail that grew mostly from the 1990s to 2010s. Its lagoon-front towers are some of the city's most recognisable, and many are now in their second cycle of MEP upgrades. Streets are busy and plots are tightly packed.
- Lagoon proximity means humid, salt-bearing air, so cooling towers, condenser coils, roof pipework and steel supports need corrosion protection and regular inspection.
- Refurbishment of occupied towers involves replacing chillers, pumps and risers floor by floor, with coordinated shutdowns agreed with building management and SEWA where supplies are affected.
- Sharjah Civil Defence typically requires fire alarm, firefighting and emergency lighting upgrades to meet the current UAE Fire & Life Safety Code during major refurbishments.
Building types we serve in Al Majaz
For office buildings, the work concentrates on VAV or FCU zoning for flexible floor plates, tenant fit-out interfaces, energy metering and BMS integration.
Approvals and authorities in Al Majaz
HVAC installation in Al Majaz sits within Sharjah's regulatory framework. The authorities you will meet are:
- Sharjah Municipality (SM)
- Sharjah Civil Defence (SCD)
- Sharjah Electricity, Water & Gas Authority (SEWA)
- ASHRAE standards (62.1, 90.1) (ASHRAE)
- UAE Fire & Life Safety Code of Practice (UAE FLSC)
Scope of work
- Heat load verification against the consultant's calculation, checking glazing ratios, occupancy and fresh-air volumes before equipment orders are released.
- Installation of AHUs, fan coil units, VAV boxes and fresh air handling units with vibration isolation, condensate drainage and service access.
- Toilet extract, car park ventilation and general exhaust systems sized to keep negative pressure where odours and fumes are generated.
- Controls wiring of thermostats, sensors and actuators linked to the BMS so zones can be scheduled and monitored centrally.
Systems we install
- Ceiling-concealed and floor-standing fan coil units
- Dedicated outdoor air units for dehumidification
UAE site and climate challenges
- Outdoor air in summer is both very hot and very humid, so fresh air must be pre-treated by dedicated units or heat recovery before it reaches occupied spaces, otherwise rooms feel clammy even when the thermostat reads 23°C.
- Ceiling voids under roofs can exceed outdoor temperatures, so ducts and pipes in those zones receive thicker insulation and continuous vapour barriers to stop dripping and loss of cooling capacity.
- Fan coil units versus VAV systems: FCUs suit hotels and apartments with individual room control, while VAV suits open offices but needs more ceiling depth and careful minimum fresh-air settings.

Frequently asked questions
Which authorities approve HVAC installation in Al Majaz?
Approvals in Al Majaz typically involve Sharjah Municipality, Sharjah Civil Defence, Sharjah Electricity, Water & Gas Authority and ASHRAE standards (62.1, 90.1). Exact routes depend on the plot, the master developer and whether the site sits in a free zone, so we confirm the authority matrix during mobilisation and prepare submissions accordingly.
Does Manolia work in Al Majaz?
Yes. Al Majaz is in Sharjah, roughly 20–60 minutes from central Dubai depending on traffic. Site teams are mobilised from our Dubai headquarters with supervision, QA/QC and HSE staff assigned to each project.
Why do some new buildings in Dubai feel humid even with the AC on?
Usually the fresh air is not dehumidified properly. If untreated outdoor air is supplied directly, or fan coils are oversized and cycle off too quickly, moisture stays in the space. Correct fresh-air treatment, right-sized coils and balancing to design flows solve this, and these are checked during commissioning.
