"Highly recommend contacting them for electrical work! Responded quickly to come and give a quote for a generator hook up. Explained everything thoroughly and gave helpful suggestions as this was my first experience getting a generator to power the house. Very reasonable pricing. From first contact to getting it installed in under 2 weeks. Very happy!!"

"Tylor was quick to respond to my inquiry and very accommodating to fix my problem as soon as he could. His expertise was shown as he diagnosed the possible issue over the phone and he had it fixed in no time once he arrived. He even fixed a lesser issue for no extra charge. I found his rates exceptional, and he will always be my first call for any of my future electrical issues."

"I highly recommend him for any electrical work! He has completed several projects at my home and has done a phenomenal job every time. He installed recessed lighting in three bedrooms and my bathrooms, as well as completed an outdoor project that required running new electrical wiring. His work is always professional, clean, and done right. He is extremely reliable, responsive, always shows up on time, and is willing to travel wherever the job is. His pricing is also very reasonable and economical for the quality of work he provides. On top of being a great electrician, he is a genuinely great person to work with. I will definitely continue using him for future projects and highly recommend him!"

"Highly recommend!! Peter was very professional and easy to work with. Came when he said he would and finished the job on time. He also returned after the installation was complete to make certain furnace was running well and to install a new CO2 monitor when he noticed mine was outdated."

"I had a small electrical fire on a Saturday from out dated cloth wire. These guys showed up got it fixed to where my house was safe and came back on a Sunday to get it 100 percent done rewiring my out door lights for my front door. Amazing professional work. They came back a little later and re wiring my entire house for me new panel new wires handled the permit. I can’t say enough about their work and professionalism I have no issue leaving them a key to work while I’m not home. Again amazing quality work"

Generator Install questions, answered by experts

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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 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.
