OK. Thanks. I've got 1 guy ready to come in and prepare a cost free estimate. I'll post the results later today.

I agree with Imudec,,sounds like your HVAC guy is looking to make a commission on a new unit.

First of all, even if there was a hole in a capillary tube, the capillary tube is on the high pressure side of the system, so there is a constant pressure from the inside out, even when the unit is at rest until all the refrigerant is expelled, therefore it is highly unlikely that it sucked in any contaminants.

If it did happen to expel all the refrigerant and then sat for any length of time it is possible that moisture laden ambient air got into the system. In a worst case scenario that could cause rusting on the compressor valves, which would be a serious problem, but that is not something that would occur overnight, it would require a least a week or so, usually more.

In any case where there is the probability that air got into the system, the proper remedy would be to correct the original problem, then add both a new liquid and suction dryer and dehydrate the system by pulling a deep vacuum before recharging the system.

If I were you I would definitely get a second opinion from a competant HVAC tech before condemning your unit.
