"I recently had an electrical inspection done by TE Certified Electrical, Plumbing, Heating & Cooling, and I couldn’t be more impressed.

They took the time to explain everything they found in a way that was easy to understand, and I felt confident I was in good hands.

"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."

"I found Mr Sullivan on HomeAdvisor gave him a call which he picked up right away which was a plus, but than he gave me an estimate over the phone without coming down to look at it made it seem like the minimum he would charge was $350 for instal of four outlets, troubleshoot and repair outlets in kitchen, and repair backyard light. The next day he arrived a little late installed four outlets as discussed, but turned out nothing was wrong with the outlets in the kitchen he said the " GFCI where doing what they were supposed to do", and the back yard light was fixed by replacing the old sensor that rain water damaged with a new one, but replaced it with a black sensor rather than a matching white, which I was fine with in the end, unfortunately in the end he didn't recalculate the fact that he really didn't had to do anything with the outlets in the kitchen yet he was still trying to charge me $25 more for the unmatching backyard sensor. I am not an electrician and he and his employee did get the job done, but was just dissapointed that I believe he did not charge a fair price for work he done seemed too expensive to me usually an instal of lights or switches are around $50 a pop and the sensor $25 itself just didn't add up to me other than that they got the mission accomplished."

Generator Install questions, answered by experts

Yes, whole-house generators run constantly for extended periods. Whole-house generators can run for longer periods of time than portable generators, but be careful. First, they may need regular applications of engine oil (as frequently as daily), depending on the engine design. Second, running constantly for several days will increase the wear and tear on the generator and shorten its lifespan.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.
