The usual causes are low refrigerant from a leak, a dirty condenser or evaporator coil, a failed run capacitor, a weak compressor, or a blocked filter. Check airflow and coils first, then pressures.
Common causes are a shorted or weak capacitor, a compressor drawing high current because the condenser is dirty or the fan has failed, low supply voltage, or a compressor winding fault. Check the outdoor fan and capacitor before condemning the compressor.
Ice usually means low refrigerant, restricted airflow from a dirty filter or coil, or a failed indoor fan. Switch the unit off to defrost, clear the airflow problem, then check the charge and look for a leak.
Most often a blocked condensate drain, an iced coil that is now thawing, a drain tray that has cracked, or a unit installed without enough slope towards the drain.
A humming sound with no start is the classic sign of a failed run capacitor. Test and replace the capacitor first; if the compressor still fails to start, the motor windings or the contactor may be at fault.
Poor heat rejection: a dirty condenser coil, a failed condenser fan motor, an overcharged or undercharged system, or high ambient temperature combined with restricted airflow. Fix the airflow and check the charge before replacing the compressor.
Check the fan capacitor first, then the fan motor itself, the contactor and the wiring. A motor that spins freely by hand but will not start is usually a capacitor; a seized or noisy motor needs replacement.
Usually mould or bacteria on the evaporator coil and in the drain tray. Cleaning the coil and flushing the drain normally solves it.
The most common causes are low refrigerant from a leak, the compressor clutch not engaging, a failed condenser fan, a blocked condenser or a failed compressor. A pressure check with gauges points to the cause quickly.
Typical reasons are low refrigerant (the low-pressure switch cuts the clutch), a burnt clutch coil, a blown fuse or relay, or a worn clutch gap. Confirm system pressure first, then test the clutch coil.
With clean coils, correct charge and a healthy capacitor, a compressor commonly lasts 10 to 15 years. Most early failures are caused by dirty condensers, low or wrong refrigerant, moisture in the system, or repeated starting on a weak capacitor.
If the unit is over 12–15 years old, uses R22, or needs a compressor plus a coil, replacement is often the better value. For a single failed part on a younger unit, repair is usually worthwhile. We will give you the part price so you can compare.
R410A runs at much higher pressures than R22 and uses POE oil instead of mineral oil. They are not interchangeable: an R22 compressor cannot run on R410A and the gauges, hoses and driers must be rated for the gas in use.
Small top-ups are common practice provided R410A is charged as a liquid from the cylinder. For a large loss, find and repair the leak, evacuate the system and recharge to the nameplate weight for reliable performance.
No. Mixing refrigerants changes the pressures and the oil compatibility, damages the compressor and makes the gas impossible to recover correctly. Always use the refrigerant on the nameplate.
R32 is classed A2L, meaning mildly flammable. It is safe when handled with A2L-rated tools, no open flames or sparks nearby, good ventilation and correct charge quantities. Use gauges and hoses rated for R32.
R1234yf is the newer, low-GWP refrigerant fitted to most cars from the mid-2010s. The two are not interchangeable: they use different service ports and the system must be charged with the type it was designed for.
The standard charge is printed on the outdoor unit nameplate and is correct for a set pipe length, typically 5 to 7.5 metres. Longer pipe runs need extra gas per metre as stated in the manufacturer's data.
Evacuation removes air and moisture. Moisture reacts with the refrigerant and oil to form acids that corrode the compressor, and non-condensable gases raise head pressure. Pull down to around 500 microns and confirm it holds before charging.
R22 systems use mineral or alkylbenzene oil. R410A, R407C and R404A use POE oil. Car AC systems on R134a and R1234yf use PAG oil of the grade specified for that compressor. Never mix oil types.
One ton of cooling equals 12,000 BTU per hour, or roughly 3.5 kW. A 1.5-ton unit is 18,000 BTU/h and a 2-ton unit is 24,000 BTU/h.
A rough guide in UAE conditions is one ton for every 12 to 15 square metres, with more capacity for sun-facing rooms, large glass areas or high ceilings. A technician should confirm the load before buying.
Rotary compressors are compact and common in split and window units. Scroll compressors are quieter and more efficient, used in ducted, package and commercial systems. Reciprocating compressors are the traditional piston design, still common in refrigeration.
No. Inverter compressors are DC motors driven by a control board and are not interchangeable with fixed-speed compressors. The replacement must match the original type and be compatible with the unit's board.
It provides the phase shift a single-phase motor needs to start and run efficiently. A weak capacitor causes hard starting, humming, overheating and high current draw in compressors and fan motors.
The expansion valve meters refrigerant into the evaporator. Replace it when it sticks open or closed, shows erratic superheat, or is contaminated after a compressor burn-out.
In the direction of refrigerant flow, following the arrow printed on the drier body. On a liquid-line drier the arrow points from the condenser towards the expansion device.
Commonly 1/4" and 3/8" for 1 to 1.5 ton units, 1/4" and 1/2" for 2 ton, and 3/8" and 5/8" for 2.5 to 3 ton. Always check the manufacturer's connection sizes for the specific model.
Because of the heat and dust, every three to four months is common for heavily used units, and at minimum a full service before summer. Filters should be cleaned monthly in peak season.
Switch off the power, remove loose debris, apply a coil cleaner, then rinse from the inside out with low-pressure water so the fins are not flattened. Straighten bent fins with a fin comb.
The suction line carries cold gas back to the compressor. Without insulation it sweats, drips and loses cooling capacity, and the compressor can receive warmer gas than designed.
Pull the system down to around 500 microns, isolate the pump and watch the gauge. If it holds for 15 to 30 minutes without rising, the system is dry and tight; a steady rise indicates moisture or a leak.
We strongly recommend it. Refrigerant handling needs recovery equipment, gauges and training, and incorrect charging is the most common cause of early compressor failure.
The nameplate lists the model number, cooling capacity (BTU/h or kW), refrigerant type and charge, voltage and phase, and rated current. A photo of it gives us everything needed to match most parts.
