Refrigerant does not naturally deplete — if your system is low on gas, it has a leak. Simply topping up refrigerant without finding and fixing the leak is money poured into the atmosphere. We locate every leak with electronic detectors, repair it by brazing or re-flaring, pressure-test the repair, and charge the system to exact manufacturer specification with calibrated manifold gauges. The result lasts — not 6 months until the next top-up.
What's Included
Heated diode and heated pentode leak detectors sensitive to 5 grams/year — the most precise portable leak detection method available. We test every joint, valve, and penetration in the refrigerant circuit.
Silver-phosphor brazing of leaking copper joints under nitrogen purge. This is the permanent repair method — not sealant injection or stop-leak products, which we do not use as they contaminate the system.
Failed or incorrectly made flare joints (at indoor/outdoor unit connections) remade to ISO 7241 standard using calibrated flare tool. The most common site of leak in poorly installed systems.
Refrigerant recovered into certified cylinder before repair (required by Saudi regulations). System recharged after repair using weighing scale method or superheat/subcooling method — not pressure charts alone.
Full service for all modern refrigerants. R22 systems also serviced — we advise on R22 phase-out timelines and retrofit options where appropriate.
Hairline cracks in condenser coils (from vibration or corrosion) repaired by TIG welding or coil replacement where welding is not viable.
How It Works
Pricing Guide
Electronic leak detection (diagnostic): SAR 200–350. Minor leak repair (1 joint) + recharge (1 kg R410A): SAR 450–700. Major leak repair (multiple joints or coil) + recharge: SAR 700–1,400. R410A refrigerant: SAR 150–200/kg. R22 refrigerant: SAR 200–300/kg (price rising as supply reduces). Note: we do not charge for refrigerant used in topping-up without confirming a leak is fixed.
Frequently Asked Questions
How do I know if my AC is low on refrigerant?
Key signs: (1) AC runs continuously but room doesn't reach setpoint temperature, (2) ice forming on the indoor copper pipe or evaporator coil (counterintuitive but caused by reduced pressure from low charge), (3) suction line feels warmer than normal (should feel cold to the touch), (4) higher than normal electricity consumption without explanation. A technician with manifold gauges can confirm low charge within 5 minutes of arrival.
Can I just top up the gas without finding the leak?
You can, but it's a false economy. R410A refrigerant costs SAR 150–200/kg, and a typical residential system holds 1.5–3 kg. If a leak causes you to top up every 12–18 months, you spend SAR 250–600 per year indefinitely. Finding and repairing the leak costs SAR 450–1,400 once, and the system runs without further refrigerant cost for its remaining life.
What is the difference between R410A and R22 refrigerant?
R22 was the standard refrigerant until 2010 and is now being phased out globally due to ozone depletion potential. R410A (and newer R32) replaced it. R22 is still available in Saudi Arabia but at rising prices as supply dwindles. If you have an old R22 system that develops a major leak, we advise: for systems over 10 years old, replace the unit with a new R410A/R32 system rather than repairing the R22 circuit.
Does refrigerant leak endanger my family?
R410A and R22 are non-toxic at residential indoor concentrations — a slowly leaking system does not create a health hazard in normal conditions. However, if refrigerant leaks into a very small enclosed space (a sealed cupboard or machine room without ventilation) in large quantity, it can displace oxygen. Standard residential leaks in normal rooms pose no health risk but should be repaired to protect the system and the environment.
