"The gentleman who showed up was prompt and very courteous, but unfortunately that was the only positive thing I can say.He was here for 40 minutes, charged me 200 dollars and told me he couldnâ t fix it in my garage, because the oil was sludge and he may or may not be able to fix it, but he would have to take it back to the shop and it would cost me 80 dollars an hour to try to fix it.When I gave him a check for his time and asked for a receipt, he looked at me like I was asking for a kidney, and wrote something down on apiece of notebook paper, which was supposed to be a receipt.It was not an invoice with the company name or any reference to their business license.I later received an explanation from somebody in the office, that they would send me an invoice for the work done.I have never had any contractor not present a proper business receipt to me when I have given them a check, prior to this."

"Dominic removed old wiring and electric fixtures in my cabin. He installed all new wiring, inside and outside lights, and designated outlets for items like a microwave oven and future hot water heater. My contractor was impressed with the quality of Dominic's electrical rough-in. After the insulation and sheetrock were completed, he returned to add all the fixtures, switchplates, smoke detector, etc. Everything looks great. I've used Dominic a couple of times, and he does a neat, professional job, always responsive to the customer's needs."

Generator Install questions, answered by experts

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
