"We wanted to try a local contractor and came across Evergreen by chance. It was an excellent experience. Thad was knowledgeable and professional and easy to work with. The crew was exactly the same. Nice, respectful, competent. The worked around my crazy schedule as we had other improvements going on. They had a slight delay in getting the generator as there was a back order, but called and let us know and we worked around it. Laurie in the office was equally good and kept us in communication on details or things to do and schedule etc. I could not be more happy with the experience on such a big purchase. They were always accommodating and helpful. The Generator and switch were high quality and I think the price was fair. They even did some easy side things for us for no charge. We will definitely use them again soon to install an attic fan."
"Fine. They arrived within a half hour of the scheduled time. Though they had to run to the store for parts for my installation, the job was performed promptly and professionally."
"Very professional service. The sale person came to verify the scope of work and provided us with a detailed quote. We scheduled the installation soon after. We had only a minor issue, becuase when the technical crew came in they realized that more work was needed (but no change in the quote). We rescheduled the installation a week after and everything went very well. The sale person remained our point of contact before, during and after the installation and he performed a follow up visit to make sure everything was fine. The technical crew was also very professional. I would reccomend them for sure. "
"It went very well, he is a licensed electrician and he changed all of my old s12 sockets to energy efficient sockets so that I could use my electronic devices and not blow circuits. I was being charged each time I called in a help ticket. So I called Mason Electrical Services and had him come out and take a look . He came out and took a look at the problem and gave me an estimate .and I was really satisfied on the price. He arrived promptly on 8 March 2014 had everything he needed to work with, and completed the work it only took a couple of hours and the job was done. In that time he installed a ceiling fan in my bedroom with a remote. He didn't make a mess. I would definitely recommend him to others needing electrical services in the future.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
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.
Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.
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.
