Honesty is the best policy, which is why an accurate quote is given to you only upon inspection of the unit in need of repair. Without inspecting your appliance and running a full diagnostic, it is impossible to quote an exact price. The cost of repair depends on a lot of different factors, including appliance type, brand, age, modification, specifications, cost of parts, etc. Beware of the companies that quote you a price of repair without ever having a look at the appliance and professionally inspecting it. You could be overpaying.
