I have a question regarding my system in FLA. It was installed in 2018, air handler inside, condenser outside. In Nov 2019 it was low on refrigerant, and after injecting dye in the system, a leak was found in the evap coil. Replaced that, charged the system with r410a, and everything was fine for a year.

which brings me to now. My siding sales rep used the condo this week and on Tuesday he told me AC wasnt working. Called the company and they told me this was no refrigerant (r401a) in the system, and after testing for leaks they found none.


My questions is, can the refrigerant be siphoned out from outside the unit and resold? If so, is there anyway to prevent this( some type of lock etc)

However what I do know is that R410 units are prone to leaks due to the pressure of the refrigerant during the hot seasons. Pinhole leaks at the u bends are a motherf’er.
