"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"They came out in the middle of a storm and promptly hooked the generator to my panel. While I thought I’d be running extension cords to my appliances it turned out that the whole house was up and running. I wish I had done this earlier. I would recommend MGT for any electrical needs. I will surely use them again."

"Incredible experience. Matt and Miseal came to my 1960s era condo in rural CT to do an assessment of what I wanted. Matt (a veritable genius) recommended in order to save time (labor $) and to help bring my aging condo into the 20th century, to install the new Lutron Caseta system. Turns out, it’s Alexa, Google, and Apple compatible, in addition to just being wireless. Over the decades, Ive wired outlets, switches, ceiling fans, and fixtures of all types many, many times. This system is light years ahead of “old school”. With a simple Echo Dot or Echo Show and the affordably priced Caseta bridge, even my adult son could easily control my lighting and ceiling fans from his house or anywhere in the world. Incredulous! This system actually becomes part of your environment, so to speak. Anyhow, I got the quote a day or so later from Equipment Unlimited and was “dead nuts” right where I thought it would be and thought was reasonable. 1 week later, everything is done, working perfectly, not a single glitch. Again… incredulous. Matt and Miseal were neat and tidy, which was great because their working with me there did not ignite my OCD. Cleaned and used a tarp as they went from one area to another. If you’re looking to electrically update your home, consider yourself freaking lucky if you get Matt and Miseal. Personable, clean, on time, reasonable and yes, even a sense of humor; a rarity among electricians. EXCELLENT JOB, Matt and Miseal from Equipment Unlimited. You made this old swamp yankee a very happy guy."

Generator Install FAQs, answered by experts

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.

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.
