Commercial HVAC & Chiller Maintenance done properly
In a UAE commercial building, cooling is usually the largest single line on the energy bill and the fastest route to a complaint when it underperforms. Chillers, air handling units, VRF systems and package units all degrade quietly through fouled coils, drifting refrigerant charge, failing belts and uncalibrated controls. The first visible symptom is normally a comfort complaint months after the efficiency was already lost.
We maintain commercial HVAC across offices, retail, warehouses, clinics, schools and hospitality. Our programs are built on measurement: approach temperatures, delta-T, amperage, static pressure and water quality are trended over time so that degradation is visible on a chart long before it becomes a breakdown or an energy penalty.
Priced after survey, never from a rate card
Every commercial scope is different, so we price after a survey rather than guessing. Tell us the building, the systems and the outcome you need.
Typical response: within one working hour, Saturday to Thursday.

How commercial HVAC and chiller maintenance is executed
The instruments we carry, the values we record, the standards we work to and the materials we install. Ask any contractor for the same four lists before you compare prices.
Instrumentation on the van
- Refrigerant analyzers and oil sampling kits
- Vibration analyzer
- Ultrasonic flow meter
- Water-treatment test kits
- Thermal imaging camera
- BMS interface tooling
Values we measure and record
- Chiller approach temperatures, condenser and evaporator
- Coefficient of performance under measured load
- Condenser and chilled water flow, delta-T and differential pressure
- Conductivity, pH, inhibitor and biocide residual in water circuits
- Vibration signature on rotating plant
- BMS reported values verified against physical instrument readings
Standards and method
- Manufacturer overhaul intervals by running hours, not calendar alone
- Water treatment program with documented dosing and monitoring
- Legionella risk control measures on cooling towers
- Testing, balancing and commissioning recorded, not declared
Materials and components
- OEM compressors, tube bundles and control components
- Approved refrigerants with recovery and reclaim documentation
- Corrosion inhibitors, biocides and scale control chemistry
Our seven-stage method
Every commercial HVAC and chiller maintenance job follows the same documented seven-stage method, whether it is a single call-out or a full building program.
Plant survey and baseline measurement
We record every item of cooling plant with capacity, age and condition, and take a baseline set of readings: approach temperatures, delta-T, amperage, pressures and water quality where applicable.
Service program design
A maintenance schedule is built around actual duty and operating hours rather than a generic annual template, with frequencies set by criticality and manufacturer guidance.
Scheduled mechanical servicing
Coils are cleaned, filters replaced, belts and bearings checked, drains cleared, electrical connections inspected and refrigerant circuits verified against manufacturer specification.
Water-side maintenance
Cooling towers, condenser water circuits and chilled-water systems receive cleaning, water treatment, dosing checks and strainer servicing to protect heat transfer performance.
Controls and calibration
Sensors, actuators, valves and control sequences are verified and calibrated. BMS points are checked against physical readings, because a control system reporting the wrong value causes more waste than a dirty coil.
Performance trending and analysis
All readings are logged and trended visit by visit. Degradation shows on the chart while it can still be corrected cheaply, rather than after a failure.
Reporting and efficiency recommendations
Each visit produces a written technical report, and each quarter we report on plant performance, energy trend and recommended interventions ranked by payback.
What sets our commercial HVAC and chiller maintenance apart
- Measured, trended data on every visit, not a tick-box service sheet
- Technicians experienced on chillers, AHUs, VRF and district cooling interfaces

Commercial HVAC in your community
We publish a dedicated page for commercial HVAC and chiller maintenance in every one of the 109 communities we serve, so you can see local considerations and response times before you call.
Four good reasons to book this week
These apply to every service we run, on every property type, without small print you have to hunt for.
Same-day slots
We hold a limited number of same-day slots each morning for urgent AC, plumbing and electrical faults. Call before 11:00 and we will tell you immediately whether one is free.
Two services, one visit
Book any two services at the same property on the same visit and the second is discounted by 10%. One trip, one team, one invoice.
Diagnosis you do not pay twice for
If we diagnose a fault and you go ahead with the repair, the diagnosis is absorbed into the job. You are never charged twice for the same visit.
Annual contract credit
Take out an annual maintenance contract within 30 days of any completed job and the value of that job is credited against your first contract year.
Commercial HVAC, frequently asked questions
Chillers and AHUs typically need quarterly attention with an annual major service, while FCUs and package units are usually serviced two to four times a year. High-duty plant in continuous operation needs a tighter schedule, which we determine from the running hours.
Yes. We service the building side of district cooling connections: heat exchangers, ETS units, valves, strainers, BTU meters and the distribution network of FCUs and AHUs beyond it.
Yes, and the mechanism is straightforward: clean heat exchange surfaces, correct refrigerant charge, calibrated controls and correct airflow all reduce the work the plant has to do. We trend the readings so the improvement is visible in data rather than asserted.
Yes. Most commercial servicing is scheduled outside trading or office hours precisely to avoid disrupting occupiers, and this is built into the contract from the start.
Yes. We begin with a full condition survey and baseline readings, produce a rectification list to bring the plant back to a maintainable standard, and then move it onto a normal program.
A written technical report with readings after every visit, plus quarterly performance and energy trending with prioritized recommendations.
