Air conditioning in Riyadh is not a luxury, and it is the hardest-working system in the car all summer. Its performance depends on a refrigerant charge accurate to the gram, a healthy compressor, a clean condenser and fans running at the correct speed. A small refrigerant shortfall does not mean "top it up" — it means there is a leak, and topping up without fixing it brings you back in weeks.
In Riyadh, 'just a refrigerant top-up' is not enough. We find why it dropped — repeated topping-up without fixing the leak ends in a failed compressor and a bigger bill.

01
We measure low and high side pressures while running, compare inlet and outlet air temperature at the vents, and watch compressor operation, the control valve and cooling fans through the tester. Those readings tell us whether the issue is a low charge, a weak compressor, a dust-blocked condenser, a restriction in the circuit, or a climate control module problem.
02
Before any refill we recover and weigh the existing charge to learn how much the car actually lost, then find the leak by pressure test, tracer dye or electronic detector. Common spots: aluminium pipe joints, the compressor seal, the condenser in front of the radiator where stones and dust hit it, and the evaporator inside the dashboard. After the repair we vacuum the circuit to remove moisture, then charge the exact weight and oil specification.
03
A smell when the A/C starts usually comes from bacterial growth on a damp evaporator or a dust-saturated cabin filter. In Riyadh's dusty air the cabin filter clogs faster than most people expect, weakening airflow and loading the system. We replace the filter, sanitise the duct and evaporator, and confirm the drain is clear so water does not pool and bring the problem back.
