"I had two sets of LED lights that were working, but not to their full power. Cameron came over, tested the wattage, tested everything that he could, and basically explain that I needed new fixtures. In that same period of time, he also checked on another fixture upstairs that we wanted replaced, but were unsure of how long it would take or what the cost would be. He was extremely kind in explaining all of his work and that the consult for this visit would be included in the billing of the next visit as he unable to resolve the problem in the first trip. The next time Cameron came, it took him hardly anytime to get all three fixtures put in. I am extremely impressed with his efficiency, communication, and attention to detail in his work. He is a meticulous and mindful person, and is very skilled in his craft. I will definitely be recommending this electrical company to friends and family, as I feel very confident in their work."

Generator Install questions, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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. 

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.
