De-icing an Evaporator Coil.

A common service call is an iced-up evaporator. As part of the repair process the coil will need to be de-iced. Avoid being too aggressive when defrosting the coil could easily cause a leak in the coil. Never use an ice pick or a metal object to de-ice a coil. The best way to de-ice a coil is with water; however this is messy and not always practical. A heat gun also works well but care should be taken not to overheat any wiring or items close to the evaporator.
