One side of the room cold, the other warm — that gap usually comes from airflow direction, a distribution fault, or declining system output. The fix depends on which pattern matches.
SAFETY WARNING
Stop using the unit and contact a technician if you notice burning or electrical smell, breaker tripping repeatedly, or harsh abnormal noise.
Air can cool one path strongly while missing other areas due to angle or obstruction. The unit may still be working normally.
We test airflow reach across the room by adjusting louvre angle and fan speed, then confirm whether the imbalance disappears with direction changes alone. Uneven room feel is not always proof of part failure.
A stuck louvre motor or worn blower wheel can weaken air spread, leaving persistent comfort gaps even after direction adjustments.
We inspect louvre motor swing range and blower wheel condition, measure airflow velocity at the outlet, and replace the faulty component if movement is restricted or uneven. Forcing lower set temperature may cool one zone more while leaving the real issue unresolved.
When total cooling capacity declines — from a dirty condenser, low refrigerant, or compressor wear — warm zones grow while the cold spot shrinks closer to the unit.
We measure supply air temperature and refrigerant pressure to confirm whether the system is delivering rated output or has a capacity shortfall. Skipping output checks can hide a larger cooling problem.
Large rooms, furniture layout, and sun exposure can create natural comfort differences even with normal operation.
If this pattern keeps worsening, move to diagnosis early.
Just observe, no disassembly required:
