Abstract: In one instance, an isolator for a heating, ventilating, and cooling (HVAC) system is provided that is a formed plastic member that is disposed between dissimilar metals of the bottom of the condenser and a base pan that supports the condenser or between two dissimilar metals of another HVAC heat exchanger. The isolator separates the two dissimilar metals involved from each of those components and also provides gaps or apertures to drain any water that otherwise might become standing water that potentially causes oxidation or increased oxidation. Other aspects are disclosed.
