"Phenomenal job by Evergreen.  Analyzed the current box and gave me options, best, most cost effective was upgrading the 40 yr old CB panel and adding a generator interlock.  Work was done perfectly and efficiently...now when the neighborhood goes dark (all too often when the weather is bad in Northern VA), we have power and AC.  Thanks Evergreen."

"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"

"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.

"He was fabulous and did a great job. It was a 20kw generator. He was very professional and came in uniform. He was thorough in discussing my options. He was able to install this in my basement instead of hanging it outside. The main reason why I'd recommend him so highly is that the unit I have is a big generator. I have it setup to run on propane. It turned out that the gas company did not lay the line within the county codes. Jim caught that and notified that. They argued with him, but the county came out and determined that it was potentially dangerous. The gas company had to redo the installation for free. He could of just finished the installation, and I would not have known the distance."

Generator Install FAQs, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.
