Weak cooling in one room, a unit that runs longer than it used to, or a power bill that climbs without a clear reason usually leads to the same question: does the air conditioner need cleaning, a gas refill or a repair? An AC service in Abu Dhabi can mean three different jobs that cost very different amounts and fix very different problems, yet in a phone call they often get booked under one name. DesiBhai Abu Dhabi, an Abu Dhabi home services company, publishes a price for each of the three on its website. This guide sets those listed prices against the symptom each job fixes, and shows how to avoid paying for a fix the unit does not need.

An AC service for dirt: cleaning restores airflow without adding gas
A cleaning covers the parts that collect dust: the filter, the indoor coil and the drain pan. The company's list gives AED 60 a unit for a split AC, AED 50 for a window AC and AED 90 for a cassette or ceiling unit, as listed on DesiBhai Abu Dhabi's website. A cleaning takes about 30 to 45 minutes a unit, and the company offers a group discount for three or more units in one visit, without publishing a figure.
Dirt is the sensible place to start, because it is usually the first thing to check. ENERGY STAR, the joint US EPA and Department of Energy efficiency programme, says in its maintenance checklist for heating and cooling that dirty evaporator and condenser coils reduce a system's ability to cool a home and make it run longer, which raises energy costs. The same checklist says a dirty filter can increase energy costs and damage the equipment, leading to early failure. If a cleaning restores the airflow, a refill or a part may not be needed.
Gas refill starts with a leak check
The refill is the job most worth reading slowly. The listed labour is AED 50 only, with you supplying the gas. The company's list also gives AED 150 to 200 with R410A gas and AED 200 to 250 with R22 gas; the final price depends on the gas used and is confirmed on site. A leak check comes before any refill, and the company says it works on R22, R32 and R410A systems.
The check matters because the refrigerant level is not a guess. The same ENERGY STAR checklist says that too much or too little refrigerant makes a system less efficient and shortens the life of the equipment, so the level should be checked and adjusted, not topped up by habit. If the unit has lost gas through a leak, the leak has to be found first.
Repair starts with a diagnosis
Repair is a different kind of job. The company's visit and full diagnosis costs AED 80. After the diagnosis, repair labour is AED 25 an hour, and spare parts are charged at cost and approved by you first. The faults it lists include a PCB board, a capacitor, a fan motor, a drain blockage, a thermostat and a remote receiver. The symptom alone does not show which fault it is.
| What you notice | The job it usually points to | Listed price and what it covers |
|---|---|---|
| Dust on the vents, weaker airflow | Cleaning of the filter, indoor coil and drain pan | Split AC AED 60 a unit; window AC AED 50; cassette or ceiling AED 90 |
| Cooling is low and the unit has lost gas | Leak check, then a refill | Labour only AED 50 (you supply the gas); R410A AED 150 to 200, R22 AED 200 to 250; final price confirmed on site |
| Water near the indoor unit | Diagnosis first; the symptom alone does not show the fault | Visit and full diagnosis AED 80, then repair labour AED 25 an hour; parts at cost, approved first |
| The fan is noisy, the unit will not start, or the remote does nothing | Diagnosis first; the symptom alone does not show the fault | Visit and full diagnosis AED 80, then repair labour AED 25 an hour; parts at cost, approved first |
What to check between jobs
Simple habits between visits can delay some of these jobs. The ENERGY STAR checklist advises inspecting, cleaning or changing the air filter once a month in a central air conditioner or heat pump, because a dirty filter can increase energy costs and lead to early equipment failure.
Keep a note of the date of the last cleaning and the last refrigerant check, and write down any change you see: a longer run time, a new smell, water on the floor or a sound that was not there before. Those notes make the diagnosis faster and stop you paying for the same visit twice. Writing down the history helps whoever diagnoses the unit.
Be realistic about what this does. Monthly filter care does not replace a leak check or a diagnosis when the unit has a fault. It only keeps the filter clean between visits.
When a yearly contract is worth pricing
If you would rather not book each job separately, the same list includes an annual maintenance contract for AC units. It covers four scheduled visits a year per unit, each with a full clean, a refrigerant check, an electrical inspection and a written performance report, at AED 350 a unit a year for one to two units and AED 300 a unit for three or more, as listed on DesiBhai Abu Dhabi's website. Parts are at cost and approved first. Compare that yearly figure with what you would spend on separate cleanings and checks for your own number of units.
Four ways to spend less without skipping the fix
- Clean before you refill. Dirty coils reduce a system's ability to cool, per the ENERGY STAR checklist, so a cleaning is a sensible first check when cooling is weak.
- Do not refill blindly. Ask for the leak check before the gas goes in. The list gives different figures for R22 and R410A gas, so ask for the final price for your gas type before the refill.
- Approve the parts first. Spare parts are charged at cost and approved before they are fitted. Ask for the part name and its price before the technician starts.
- Group the visits. If you run three or more units, put them in one visit to use the group discount. The company lists no figure, so ask for the discount in writing before you book.
Questions to ask before you book
Is the listed price the final price? The prices are the company's published list, as listed on its website. Ask for the figure for your own unit before any work starts, and expect the gas price to be confirmed on site.
Should I refill the gas before anything else? Not as a first step. The company lists a leak check before any refill, and dirt is usually the first thing to check.
Will a cleaning fix weak cooling? Only if dirt is the cause. A cleaning removes dust from the filter, indoor coil and drain pan. A failed capacitor or a faulty thermostat needs the diagnosis and an approved part.
