Josh was excellent in his workmanship. It took him an hour or two to figure out my washer dryer issue, but he was so patient to identify the issue and got to the root cause. He also made sure that I am not overcharged for any part and he was so professional punctual, and his work was the highest quality. Josh was excellent in repairing my washer dryer.

Thank you so much for your thoughtful review! I really appreciate your patience while I worked through the washer and dryer issue—sometimes those problems take a bit of digging to get to the true root cause, but I’m glad I was able to get it sorted out for you. It means a lot to hear that you felt the pricing was fair and the service was professional and punctual. Providing high-quality work and making sure my customers are taken care of is always my top priority. Thanks again for your support—I’m here anytime you need help in the future! — Joshua Monteverde GM KINGDOM WORKS

Josh was available when I requested help. He came by and fixed my gas grill - saving me $500 on a new one! He also replaced the knob on my oven with the original knob. (Previous repairman put a cheap replacement knob on but Josh k ew what to do to put the original one back on.). Glad to have a go to person when I need something at the house in Flagstaff.

I truly appreciate your trust and support, and I’m always here whenever you need a hand around the house in Flagstaff. Looking forward to helping you again in the future! – Josh GM Kingdom Works LLC
