Refrigerant refill service for 12,000 BTU air conditioners

A 12000 BTU air conditioner is one of the most popular choices for residential and commercial spaces up to 35 m². It’s designed for daily, long-term operation — especially during hot seasons.
However, even a small refrigerant leak can significantly reduce performance.
An incorrect refrigerant level leads to pressure surges, compressor overheating, and decreased efficiency.

Main causes of refrigerant loss:

▪️ Loose connections or outdoor unit vibrations;
▪️ Installation errors or factory soldering defects;
▪️ Invisible microcracks in piping;
▪️ Violation of recommended temperature ranges;
▪️ Lack of regular maintenance.

Signs you need a recharge:

▪️ The unit blows air but doesn’t cool;
▪️ The room stays hot even when running;
▪️ The system runs constantly with little to no effect;
▪️ Ice forms on the indoor unit;
▪️ Your electricity bill has gone up noticeably.
