The sides of your condenser unit are a set of fins that allow air to flow through. If your fins are dirty, blocked, have weeds or long grass around them, or a pile stuff on the unit, air cannot flow in well. This will damage your condenser.  If your condenser looks like the one above, please call us right away. We have cleaning agents to dissolve the organic material and get air flow going again.  We will then test your unit for any damage. If your condenser has plants growing out of the fins...its may be time to put it to pasture...
