"Yuri and his team did a fabulous job on upgrading my electrical panel and installing a whole house generator. Their work was meticulous, precise and clean and the inspector was very impressed with their work. The quote for the bid was fair, honest with no headgames or BS and this is important for women. I am glad I hired this company and they do guarantee their work."

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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.
