Arrived today for no cooling on 2000 7.5 ton Lennox gas package unit. Found breaker tripped to equipment. Reset breaker to unit. Compressor is making a noise and pulling high amps. System is 25 years old and could break again at anytime but it’s working at this time. Customer stated maintenance guy was here yesterday but don’t think that had anything to do with unit tripping breaker just very old equipment.
