AC Commissioning and Testing in Masdar City

What is included
Supply and installation of split, ducted, cassette and multi split air conditioning for Abu Dhabi homes, offices and shops, sized to the room and tested at handover. Most cooling complaints in Abu Dhabi trace back to the day the unit was fitted: a pipe run too long or kinked, lines never vacuumed, a drain with no fall. Our own technicians check the room load and the power supply first, fit the unit to the manufacturer's instructions and record the temperatures on a test run. We fit a unit we supply or one you bought, and say so plainly if it is the wrong size for the room.
- Nitrogen pressure test held and the gauge reading logged
- Vacuum pulled and held on the gauge before the valves open
- Running current and voltage compared with the nameplate
- Supply and return air temperatures recorded at each unit
How we carry out AC commissioning and testing
Before start up the pipework is pressurised with dry nitrogen and the joints are checked with leak detection fluid. The system is then evacuated with a vacuum pump until the gauge shows it is dry and holding. Electrical connections are tightened and the voltage is measured. With the unit running we record the operating pressures, the compressor current, the air temperature going onto and coming off the coil, and the condensate flowing at the drain. Controllers and safety cut outs are operated in turn.
Many units in Abu Dhabi are switched on and handed over on the strength of cold air at the grille, and the faults show in the first summer: a slow leak, a low charge, a fan wired to the wrong speed. A record of readings from day one gives every later service something to compare against. We also test systems fitted by others, for example after a fit out. The site visit checks access to each unit and whether drawings exist. Where a building or its consultant has to witness or accept the tests, that acceptance is theirs.
How it works
The same method on every job, so the result does not depend on who is on shift.
- Survey and diagnosis. A technician inspects the system or surface, takes readings and photographs, and explains what was found in plain language.
- Written quotation. You receive a written quotation against a defined scope before any work starts. Anything outside that scope is quoted separately.
- Protected, supervised work. The work area is protected and isolated, and the job is carried out by our own technicians under a named supervisor.
- Testing. Every job ends with a measured test suited to the discipline, so the result is a reading and a photograph and not an opinion.
- Report and warranty. The completed report reaches you within the hour. Any failed point is put right free of charge within 48 hours.

AC Commissioning and Testing in Masdar City: what we plan for
Masdar City is a planned low carbon district near the airport, built with narrow shaded streets and low rise buildings. Its homes are mainly apartments and townhomes in Oasis Residences One and Two, The Gate and Leonardo Residences.
The city is surrounded by open desert, so fine sand blows through the streets and settles on balconies, screens and window ledges. Shaded courtyards stay cooler but slower to dry after washing or rain. Filters and coils clog with fine desert dust faster here than on the coast, so AC servicing is planned more often, with drains and fan coil units checked at the same visit.
Residential buildings ask for a work permit and a lift booking through management, and townhomes in gated clusters need the resident to register our crew. These are confirmed at the site visit and we prepare the paperwork asked for.
What your quotation depends on
A quotation for AC commissioning and testing in Masdar City follows a site visit. The supervisor looks at the points listed here and you receive a written quotation with a defined scope before any work begins. Once you accept it, nothing is added on the day.
- Size and type of the system or surface
- Present condition and ease of access

Questions about AC commissioning and testing in Masdar City
What does AC commissioning and testing include?
Commissioning is the measured check that an installed system works as designed: pressure test, vacuum, electrical checks and a test run with every reading written down. The work includes nitrogen pressure test held and the gauge reading logged; vacuum pulled and held on the gauge before the valves open; running current and voltage compared with the nameplate.
What do I receive after commissioning?
A sheet for each unit showing the pressure test, the vacuum reading, the voltage, the running current and the air temperatures, with photographs. It comes with the 14 Point Standard checks signed by the supervisor.
Can you test an AC system that another company installed?
We can. Our technicians inspect the installation, run the tests and report what they find in writing with photographs. Faults are listed with the work needed to correct each one, and that work is quoted once you have seen the report.
How much does AC commissioning and testing cost in Masdar City?
We do not publish prices, because no two jobs are the same. The main factors: size and type of the system or surface; present condition and ease of access. Book a site visit: a supervisor from The MELLS looks at the work and you receive a written quotation with a defined scope before anything begins.
Who provides AC commissioning and testing in Masdar City?
The MELLS provides AC commissioning and testing in Masdar City, Abu Dhabi. The work is carried out by people The MELLS employs directly, under a named supervisor, 08:00 to 19:00, Monday to Saturday. To arrange it, book a site visit on this page or call +971 55 444 0084.
How long does AC commissioning and testing take?
Typically half a day for one split unit, longer for ducted systems. The time for your property is confirmed with the quotation.
Can you install a unit I have already bought?
Yes. We fit units supplied by us or by you. If the one you have bought is the wrong size for the room we tell you before it goes on the wall. An oversized unit cools fast but leaves the air damp, and an undersized one runs all day without reaching the set temperature.
What size of air conditioner does my room need?
Capacity follows the heat the room gains, not only its floor area. Glazing that faces the afternoon sun, ceiling height, a roof directly above, the number of people and any kitchen or equipment all add load. We measure and work it out at the site visit.
Can a split unit be fitted in any apartment?
No. The building decides where an outdoor unit may stand, and towers on chilled water do not take split units at all. We check the system and the building rules at the site visit and prepare the paperwork that management asks for.
Do you arrange the building permit in Masdar City?
Yes. Most buildings ask contractors for a work permit, trade licence, insurance and staff IDs, and a service lift booking. We submit all of it for you.
Do you work in Oasis Residences and The Gate?
Yes. We arrange the building permit and lift booking with management, and visits are by appointment, Monday to Saturday, 08:00 to 19:00.
How do I choose a company for AC commissioning and testing in Masdar City?
Ask four things: who employs the people who will come, whether the scope is written down before work starts, how the result is checked, and what happens if something is missed. The MELLS uses its own staff, quotes in writing after a site visit, checks every job (a measured test for every job, with photographs before and after) and puts right any failed check free of charge within 48 hours.
How are visits to Masdar City arranged?
Visits in Abu Dhabi are booked by appointment between 08:00 and 19:00, Monday to Saturday. Call or send the form and we agree the earliest time a supervisor can come to you.
