Yes I have a goodman unit, every time I turn it on the lights flicker, and it blows the breaker. Someone said it sounded like the compressor, if so isn't there a warranty

How would we know about a warranty if we don't know how old the unit is or if you bought an extended warranty.

Give us some other info and maybe we can help. Info like date of purchase, model number and serial number of outdoor unit.

Go to goodmanmfg.com you can look up warranty info there.
