"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

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. 

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.
