"Drew and the entire crew made this experience seamless. The installers were polite, friendly, competent and and tidy. The pre and post support was fantastic, the expectations around logistics, installation timing and ongoing service support was spot on. These guys are pros and the solution cost was clearly the best in my search for authorized service providers of Generac generators. Hire them you won't go wrong. Vin M Dover NH"

"Mike was great! He was quick to respond and had experience installing EV charging stations. We set up an appointment for him to come and do the work and he arrived at exactly the scheduled time (7:30 AM!). Once at the house he set about doing the work and in a short time he was done and ready for us to try the new charger. The quality of the work was superb and he could not have been more pleasant! And best of all his rates were more than reasonable. Mike is now our official, go to electrician!"

Customers say: True professional

"I needed a level 2 charger installed for my new EV, so this was very short notice. Jeff came up right away to examine the property (and this was a Sunday). The very next day he came up with his helper and got started on the project. Very thorough, professional, very friendly, on time, etc. I absolutely recommend him, and any further electrical projects I need done he will be the first person I call."

"Not only did the electricians promise to come to install the stovetop as soon as it came in, they came a few days after we first made contact to see what the work would entail and agreed to dispose of the cracked stovetop for us. They kept their promise by coming the day after the stovetop came in, worked efficiently and made sure it worked properly before leaving. My husband and I were extremely impressed with their work."

Generator Install FAQs, answered by experts

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.
