Generator Repair Cost Guide

In the event of an electrical power outage, having a generator can be an immense source of relief. Home generators can power equipment such as a sump pump or a charger for cell phones. They can also provide electricity to run a refrigerator, freezer and oven to enhance food safety and homeowner comfort in an emergency. As mechanical devices that are hooked up to electrical systems, generators that are malfunctioning require a careful and experienced professional to make any needed repairs.

The Average Cost to Repair a Generator

The average cost of repairing a home generator is $286, with most homeowners paying between $258 and $314 to have the work completed by a handyman. The actual cost to a homeowner will depend on the type and size of the generator as well as the scope of the problem, and any electrical issues will need to be sorted out by a licensed electrician, who may charge as much as $150 per hour. Any gas supply issues will require hiring a licensed gas contractor for repairs.

What to Do Before Calling for a Generator Repair

Taking a few minutes to troubleshoot the generator might save you the cost of a repair visit. Be sure that the power cord to the generator is not damaged and that it's plugged into the home's electrical system. Be sure that the generator has fuel. Check your home's electrical meter for possible problems on the outside of the home. If none of these is the source of the problem, then it's time to call for professional repairs.

Types of Generators

There are two main types of generators: portable and permanent. Portable generators use fuel, usually gasoline, to power the generator and produce electricity. Standby generators are usually permanently affixed to the home's mechanical system and are operated with fuel from a natural gas line or a propane tank. Generators range in size from 7 kilowatts to 45 kilowatts. The smaller the generator, the less it will cost to fix. A portable generator will cost less to repair than a standby generator.
