Additional appliances will incur diagnostic fees of $45-$85 each. After diagnosing your machine, the complete repair price, including all service fees and parts costs, will be quoted to you up front. You can decide whether or not to go forward with the repair. *The tightest time range we can our customers is a 3 hour window, since we are usually coming to your home after one or more other jobs. Additionally we will always call you when we are approximately 30 minutes away to let you know exactly where we are. Thank you!
