21APR2022 Jason B Arrived for no cool on 1 ton mini split. Spoke with Ron about the systems performance. Everything is running, however it’s not cooling. Used 28oz 410 provided by customer, got low side pressure to 80 but still freezing at the lineset. Added 3 lbs of 410. 105 low side and 58 degrees at coil. Performed complementary leak search, but found no leaks. This system is cooling properly at this time. If the system loses its charge again I recommend recovering refrigerant, and reinstalling the equipment, with a new vacuum and pressure test. System is running properly at this time. It was great meeting you Ron and thanks for the coffee!!
