Some appliance repair professionals charge a flat rate, while others may charge by the hour. Contact a few qualified appliance repair contractors near you to get estimates, so you can compare the costs side-by-side. Issues that require new parts may cost you more since the contractor will need to purchase and order the part and pay to have it shipped before it can be installed. Emergency repair calls will usually cost more, too. Most appliance repair professionals have an emergency rate, especially if you need help after hours.
