Generator Install FAQs, answered by experts

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
