"Keep Smiling sent me Roy Wint and I'm very glad they did. Roy installed a replacement ceiling fan as well as four recessed lights. The result of the project is a much better lit and livable living room. I want to extend special kudos to Roy. He was very professional, polite, and friendly. A joy to have working on my home. He went out of his way to avoid creating any holes in the ceiling other than those housing the lighting fixtures. And he also did a safety inspection of my home's fuse box. I can't say enough good about this young man. I'll definitely be calling him the next time I need electrical work done in my home."

"Consumer beware!!! This electric company put a lien on my house for work that wasn't completed. They were well aware that the contractor was paid in full and he needed to be the one to pay them but they decided to put a lien on my property anyways instead of taking the contractor to court. The work done was poor quality and they used the wrong rated wires on an outdoor structure. They left our bathroom electrical hanging out of the wall and didn't even put outlet covers on the new outlets. We have been forced to obtain legal representation to get this sorted out, please save a massive headache and money by using any other electric company than dependable electric services."

Generator Install questions, answered by experts

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.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn’t ideal if you want to extend the life of your generator.

Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn’t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.

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.
