"We highly recommend J.P. McCurdy Electrical Services. We hired this exceptional shop to replace all the old knob and tube wiring (along with switching out a number of light fixtures and installing several ceiling fans) in our 120-year-old Victorian home – a challenging job that a couple of other electricians didn’t feel confident undertaking. Owner Jack McCurdy personally came to size up the job and give us a detailed estimate, and his professionalism, courtesy and extensive knowledge sold us. What was originally thought to be a two-week job was finished in six working days as foreman Joe Costain efficiently deployed his crew and brought in a second crew on a few days to expedite the work. Joe was great at communicating what kind of activity we could expect day-to-day, especially as both my wife and I are working from home fulltime during the COVID pandemic. He and the crew checked in frequently on our preferences, minimized the number of holes in the ceilings and walls (including avoiding harming our wallpaper in a couple of rooms altogether), and cleaned up well at the end of every day. Jack’s estimate was competitive and the final accounting accurately included the additions and subtractions we agreed to during the job. We feel so much better that we’ve finally eliminated the risky knob and tube wiring and updated the entire house’s electrical system. McCurdy is a full-service shop that does all kinds of electrical work – if you want a trustworthy and capable electrician, give Jack a call!"

"Amaury was very professional and did a good job. We delayed the work until we could take delivery of our generator so that he could test everything together and go over the transition with my wife and I. He was neat, accommodating, patient and thorough in describing how things worked. I would recommend him."

Generator Install questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

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

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

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

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.
