Rheem units have a metal jacket around condenser coil. There not easy to clean without taking jacket off. If you don't have a lot cotton or dogwood dander you should only have to clean that coil every few years. I assume you have a heat pump. In Michigan we have bad cottonwood trees. If the tech pulled jacket off and cleaned with a hose or power washer that's not a bad price. If you want more info PM me your info.
