Normal air-conditioning system will have water condensate in the indoor unit (Fan-Coil) & flow out through a drainage pipe. If the drainage pipe is chocked, water will start to leak.
When the unit freezes up, water will start to leak too. Call a qualified technician to rectify the problem.
Why is the air-con operating more than 1 hr but still the room is not cold?
There are a few factors need to clarify
Air filter or condenser clogged.
Indoor & outdoor coil choked.
Blower clogged & dirty.
Refrigerant leak in the system.
Faulty compressor (no compression)
Why does the indoor unit freeze up?
Due to lack of refrigerant.
Faulty capacitor or fan motor.
It may simply need to carry out chemical overhauling, due to indoor coil choked.
Why is the air-con noisy?
Vibration from the indoor or outdoor motor due to dirty.
Mounting or component from the system loose.
Faulty expansion value from the indoor unit.
Why does the air-con need chemical overhauling?
When the air-conditioner, condenser & evaporator get badly chocked, (internal & external) normal servicing can't improve the condition. Chemical overhaul need to be applied. The unit needs to be dismantled & strip part by part. Apply the coil with chemical & wash out with water.
