Refrigerant refill service for 18,000 BTU air conditioners

18000 BTU air conditioners are designed for larger rooms, offices, and industrial spaces up to 50 m². During intensive use, especially in the summer, these systems run at full capacity — and even a small refrigerant leak can drastically reduce efficiency, overheat the unit, and cause compressor failure.

Why refrigerant is lost in 18000 BTU systems:

Vibration stress on connections;

Metal fatigue in piping;

Excess pressure after hot seasons;

Installation or charging errors in the past.

Signs of low refrigerant:

The AC blows warm air in cooling mode;

Takes too long to reach the desired temperature;

Frequent on-off cycling;

Noise, hissing, or vibration from the outdoor unit;

Ice buildup on pipes or evaporator.
