My mini-split system was not cooling enough, and was shutting down after running for a short time. The technician arrived on time and went right to work. Diagnosed the problem as a leak and found the leaking fitting quickly. Recovered the remaining ...refrigerant is the unit, pressure tested the unit for other possible leaks, evacuated the system which held a good vacuum and recharged and tested the repaired system. He explained each step of the process so I could understand the work required to return the AC unit to like new condition.Read More...
