Performed diagnostic on system. Replaced batteries on thermostat. Cycled for cooling. Unit kicked on and started cooling. Temperature is blowing cold.. Amp draws on compressor are at 24 out of a rated 28. System is in very poor condition. Condenser is over working like crazy, and is basically buried into the floor at this point due to it never being set in properly. Advised client of system conditions. Explained that due to condition of the system, she fully understands and is not looking to take care of anything drastic at the moment as they do not live in the home during summer, but do come down for a weekend or two. System is operational upon departure, but is very possible that unit will fail again due to conditions.
