"Highly recommend!! In 16 years, we have never had a need for a generator. We were told we were on the hospital grid. Well, apparently, those grids change. Over the last year, we have had too many electrical problems with long outages leading us to come to the decision that it would be prudent for us to buy a generator. After doing the research and seeing all the details involved with ordering, preparation, installation, etc, we decided there are too many important details and decided to look for someone to do everything for us. It's incredibly important to know that we came to this decision in December, 2020 (height of generator demand), during a pandemic and during a time of an extreme nationwide generator shortage. While researching, we saw so many people waiting months for a generator from other companies, trying to do everything themselves, waiting for the transfer switch, then an electrician and so on. We figured we would be lucky to have it for next winter. We met with Matt Sanford, he went over everything in detail, looked at the potential sites for the generator and the propane tanks, measured, etc. He could have sold us a bigger generator, but he thought it would be a waste for us to spend extra money on a specific generator I "assumed" we needed. Matt determined the size needed, made recommendations and we, happily, gave him a down payment check. He said 4-6 weeks. I still had my doubts, but here I am writing a review 4 weeks later, because the installation is complete. It is a two-day process. The workers who installed it showed up shortly before the expected time with masks on, were clear and concise, informative, professional and were very courteous of their surroundings including inside the house. In all honesty, I was floored with their demeanor. They completely took me by surprise and it was well above my expectations. When they called to book the installation, I was told the electricity "could be" out for several hours. We planned for several hours. When they arrived, they said it would be an hour or two. It was out for 15 minutes. They do as much as they can in advance so the power is out for as little time as possible, but there can be issues. DO NOT plan that your power would be out for that short period of time. Plan for the worst and hope for the best. The next person, who installs the gas portion, arrived bright and early the next day. He was just as nice, informative and professional as the workers the day before. The communication from the company is stellar. The people they have working for them are fantastic. I cannot say enough good about our entire experience. You WILL NOT be disappointed. By the way, here's something I didn't even know existed until Matt told me about it. Ask about the house surge protector. Even my insurance company had never heard of it. I wish I had known about it when it came out. Also, based on the work involved with the generator, it is comforting to know we are paying them for maintenance, monitoring, etc. In my opinion, this is a complicated machine to install and maintain. They see everything our generator is doing and if something is not right, they'll send someone out before we even know something is "not right". You don't want to be caught in a major outage and have a failing system. You go through the big expense of buying it and installing it, make sure it's taken care of on a regular basis by a professional just like your car, home heating system, etc. I highly recommend this company."

"We were very happy with the work.Eric was easy to work with. He installed a new 220 circuit and was able to fish it though the walls harmlessly whereas other electricians we talk with were going to tear up the drywall. Pricing was very reasonable. Highly recommend."

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
