Is low refrigerant gas the main reason for poor cooling in Changan Kalams AC system in Pakistan?

Frequent need for gas refilling could point to a leakage problem. Are Pakistani users facing hidden gas leaks that go unnoticed during servicing?

Yes, low refrigerant gas is one of the most common causes of weak cooling.

This is usually due to small o r hidden leaks in the condenser, evaporator, o r hose joints.

In many cases, gas is refilled without identifying o r fixing the root leak — a bad practice.

Pakistani workshops often skip using leak detection tools UV dye o r nitrogen pressure test, leading to repeat refills every 3–6 months.
