Mr. Appliance specializes in appliance repair and maintenance to keep your appliances in peak working condition. But repairing your appliances is only part of the job. Our goal is to deliver superior service by taking extra steps to protect your home and become your preferred appliance repair expert. Calling Mr. Appliance ensures: * Prompt, efficient attention * Our ""leave no trace"" clean-up commitment * A solid quote before the service begins - no surprises * Courteous and skilled in-home service professionals * Never an over-time charge - we charge by the job, not by the hour * All work & parts guaranteed Mr. Appliance is locally owned and operated and is part of the largest and fastest growing full service appliance repair company in the world. When your appliances are in need of repair, contact the appliance repair experts at Mr. Appliance.

"We called Mr Appliance in June to help with a smell in our dishwasher. At that time the tech told us he found what he thought was the source and remedied it. He also informed us that if the smell comes back within a year it would be covered under warranty. Fast forward 3 months later, the smell is back. When we called to ask about a followup visit they proceeded to say it was not covered under warranty and charged us another $140 to come out for diagnostics... okay, cheaper than a new dishwasher, please come out. On scene the new tech tells us he cannot find anything wrong. Proceeds to tell my wife to clean it more often then charges us another $50 for customer consult. $190 later we're in the same spot + a HUGE scratch on our hardwood floors. Would not recommend. I am in the process of following up for refund of the $50. 😡"
