"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."
"I was pleasantly surprised at their careful and thorough approach to the installation. They also were the most competitive bid with Cropp Metcalf being $3000 higher with less equipment. They are a local gem in a crowded field which should not be overlooked by savvy consumers"
"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.

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.
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
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.
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.
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.
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.
