No cool: Package unit system tripping breaker in both heat and cool modes. Unit is a strait cool with a 8kw heat kit. Found bad breaker racing and causing heat to build up in the breaker. In heat mode, system pulling 31 amps which is within factory spec. Homeowner will have breaker changed with someone else. I disconnected power to unit at out door disconnect until then. Compressor was recently changed by a different company under warranty. Homeowner purchased taps maintenance program with us. The office should call to set appointment for first Homeowner is aware system will not run until breaker is changed out.
