"I have used Pipe Works on numerous occasions as of this date and find them to provide excellent service at competitive prices. Their associates are great to work with and their prices are competitive. The work is always completed on time, as promised and the work area is left clean. I appreciate that they point out things that need repair in the not so distant future. It was great to wake up the other day with power coming from my new Kohler Generator"

"Ken and his team from Transform Electric were terrific! Ken immediately contacted me and was able to come and give me an estimate right away. We started the project a few days later. I had four rooms that needed new recessed lighting installed. The team came on time and started working. They were very professional and reliable. They moved all my furniture and covered what was necessary. When it was all done, everything looked great and I was very pleased with the outcome. They also cleaned up after they completed the job. Overall they did a fantastic job and I would definitely recommend them to others!"

Generator Install questions, answered by experts

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

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
