Called out today due to no cooling. Condenser was tripped on lock rotor amps. I found that the hard start has failed. Replaced hard start and tested system operation. Checked refrigerant pressures. Measured the temperature drop across the coil. Made client aware that the system will coil at about a degree an hour. Need to return tomorrow to install larger hard start. Installed smaller one tonight for temporary cooling. In need for a ks1 for 3.5-5 ton hard start. Equipment is operating properly at this time
