"Generators of Maine just completed the installation of a 14kw generator with parallel transfer switches, to protect 2 separate metered panels at a rental property that I own. I didn't even know that this was possible, until Doug Sawyer suggested it. The incremental cost of protecting the additional panel with the parallel transfer switch arrangement was a fraction the cost of an additional generator and transfer switch. Throughout the job, Doug and his crew were awesome. I am a terrible snoop who enjoys technology, so I hung around just watching and learning. They didn't seem to mind my presence and were friendly and informative through out the install. Every aspect of the job was 100% top-notch. Doug also managed to under bid his nearest competitor on every component and aspect of the job, including the annual maintenance contract, which I deemed to be worth the $$$. I highly recommend Generators of Maine."

"Kevin called me the same day I posted the pro request. I scheduled him to come by to do a quote two days later and hired him at that point. Kevin replaced a scary exterior electrical outlet and power cord that powers a pool pump. The power cord was coming out of the ground and arcing and the old outlet was melted around a socket. Not good. Kevin fixed it right up and replaced and greatly improved the whole set up, including installing an exterior outlet and switch that are both protected by the weather. Very impressed and will hire Kevin again."

"Advanced generator systems did an amazing job installing a whole house generator. They were extremely polite, knowledgeable, professional, and courteous. They went above and beyond by explaining all aspects of the functions of the generator. They were extremely clean as well. You would not have even known they were there. They started in the AM and the generator was running by the end of the day! Andâ ¦their pricing was amazing. This is a company you should hire!!"

Generator Install questions, answered by experts

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
