We recently refurbished a large condenser unit with obvious frost damage to some of the coils, this is something we regularly receive calls about during the winter months.
Frost damage can be identified by bulging or cracking of the tube bends and is usually the result of water or condensate remaining in an inactive coil during freezing temperatures. Sometimes the frost damaged coils can be repaired and stop the leak, but good maintenance and care of a dormant coil are needed to help prevent future problems.
If a coil is not in use, and freezing temperatures are likely - we would suggest draining all fluid from it, then using air to blow out the coils through the terminations (not using vents/drains). We would also advise, for optimum protection, to then flush the coils with antifreeze/glycol solution using a pump.
If you do have a suspected frost damaged or leaking coil in your system, if possible, remove and send to Beehive for a repair cost or quotation for a replacement unit which we can supply on a fast lead time to assist.
