Have a 10 year old Rheem system. Had extensive work completed on outside of home. During process line set was pinched and pierced by falling concrete. End result, unit was disconnected to prevent further damage the incorrect way. By the time we realized the line was pinched and leaked, it was too late to say refridgerant. With the heat on its way we need to have reconnected and charged. I've heard two different scenerios by multiple reliable sources. Several are saying it can be reconnected and will work fine taking the proper steps such as installing a "dyer" to the line others have said that since the compressor sat with the valves open it most likely will not run properly.
Any advice on which way to go? Not in position to get a new unit installed, but will if need to. The person saying to add dryer are United Refridgeration and the contractor and other supplier are saying to replace.
