Since no other units or electronic apparatus is blown, its kinda hard to believe that one component of an a/c system would be the only thing blown. if you have any means of testing for voltage in your system and are not squeemish of using it, I would say start at the source and go downline checking out things. the air handler is on one breaker, the compressor and condenser is on another breaker. the compressor probably has a contactor, same as the condenser fan. the control circuit is I would think 24 volts and is protected by a small fuse on the control circuit transformer. check for 240 volts on the breaker, on the line side of the contactor and the primary side of the control transformer. check for 24 volts off the secondary of the control transformer. if there are small circuit breakers in your control box reset them. if there is an overload on your compressor contactor, reset this. if you have voltage present , turn the thermostat down to 50 or below and listen if anything clicks. if the compressor tries to turn on but pops its reset right away, it may be just jammed or the windings may be burnt. call out the tech and have him try a hot start on the compressor or have him reverse the compressor. reversing the compressor can break it loose.
