Northern Machine & Repair

I recently brought a pressure washer to fix, the claimed the Money under warranty but they didn’t do nothing I’m not sure what kind off “Technician “ work in this Shop, to my opinion it is a very dishonest Company they tried to get the Money out off my Pocked as well so I Phoned the Company where I bought the Pressure Washer and I been told from Generac they already Claimed under Warranty agreement, I really can’t figure out why the wanted Money from me also
