"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."

Generator Install questions, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

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.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.
