Important Information Before Requesting Service
Is support available 24/7?
Yes. Calls and WhatsApp requests are accepted 24/7; on-site visits run from 9 AM to midnight.
Which payment methods are accepted?
Cash, bank transfer, STC Pay and barq.
Do you repair appliances that show error codes?
Yes. Send the brand, model and displayed code. Error-code meanings vary between brands and models, so the appliance is diagnosed before the cause is confirmed.
Why is my AC running but not cooling properly?
Possible causes include dirty filters or coils, restricted airflow, faulty sensors, or an outdoor unit that is not operating correctly. We check the cause before recommending a part replacement or refrigerant work.
Does weak cooling always mean the AC needs a gas refill?
No. Weak cooling can also come from dirty coils, electrical faults, or fan problems. If testing confirms low refrigerant, we check for leaks and address the underlying fault as appropriate before recharging.
Do you work on split, window, cassette and central AC systems?
Yes. We inspect split, window and cassette AC units as well as ducted and central AC systems across Riyadh. The repair depends on the model, fault and condition of the unit.
