Background: Carrier Infinity 25HPA336A Heat Pump which is only 4.5 years old but has had the system go flat twice because of a crack at the suction line to the accumulator. The system has twice had the crack soldered back up and recharged. The heat pump is now icing over again and my bets are that I have another crack at the same spot (pics included).
I am guessing the issue is with the compressor in that its vibrations are causing these issues but could it be something else? What are my options? Should I get the whole unit replaced and should it be covered under warranty? This thing is driving me crazy and draining my money, I would just like to go one year without having any HVAC issues.
