What the price includes
A repair price usually covers the call, a check of the unit, labor, and the new part. Modernize lists a service call at $45 to $100. Costs extra: a new transfer switch, wiring, a new battery, or a new circuit. Angi lists circuit installation at $570 to $1,000. Oil and fuel may be billed on their own. It does not include tax or extras the provider adds on the day.
DIY or hire a pro
You can do small jobs yourself. A battery, a spark plug, or an air filter swap is simple on most units. Always turn the generator off and let it cool first. Hire a licensed pro for the transfer switch, wiring, the fuel system, or the engine. These jobs involve power and fuel, and a mistake can cause a fire or a shock. Modernize lists a transfer switch replacement at $500 to $1,000. Angi lists circuit installation at $570 to $1,000. A pro can also check that the work meets local code.
How to tell you need it
Signs you need a repair include a generator that will not start, runs rough, stalls, leaks fuel or oil, or does not give power when the grid goes out. A weak battery or old spark plug is a common cause. Do a monthly test run so you find problems before a storm. Call a pro if a fault light shows or the transfer switch does not click over.
How to judge your quote
- Does the quote name the part that failed and the labor cost?
- Is the service call fee added to the bill or taken off it?
- Does the shop work on your brand and size of generator?
- Is there a warranty on the new part and the work?
- Compare the total with the range above: $80 to $800 per repair for most people in 2026.
Ways to pay less
- Service your generator each year. HomeAdvisor lists yearly upkeep at $85 to $706, which can cost less than one big repair like a stator at up to $1,500.
- Test run the generator once a month. Early signs like a hard start are cheaper to fix than a full break down in a storm.
- Change the battery and spark plug yourself if you can. Modernize lists a battery at $60 to $150 and a spark plug at $55 to $95 with a pro.
- Get two quotes for any repair over $500. A stator, rotor, or engine job can differ a lot from shop to shop.
- Ask if the generator is still under warranty. Some parts are covered for years, so check the papers that came with it.
Why this costs more in 2026
Trade labor now runs about $75 to $150 an hour in most of the US. Lumber, steel, copper, PVC and concrete all cost more than in 2024, and freight went up after the oil shock that began with the Iran war in February 2026. Generator repair costs more in 2026 when the stator and rotor fail, because Angi lists that part alone at up to $1,500.
