"My solar panel system had electrical problems and the original installer has gone out of business. Solar Panels were not listed specifically about so I chose something close. The Allset technician worked with the manufacturer, and made the repairs. Everything is working well now."

"The price was a little bit high. They had to do a lot of cement work to install this patio light. He built a substantial concrete structure to secure this light because of the high winds we have in this area. Yes, I would use them again in the future."

"I have been using them for 3 years for multiple projects and would not go to somebody else. They also built a cabin in the woods. It was built 10 miles from the road so it was like carrying all the stuff up the path. They also did the garage and remodeling of the house, mostly kitchen and a little bit of plumbing work in the bathroom. I am still using them and I would be using them for the next thing that will be coming up too."

Generator Install questions, answered by experts

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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. 

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.
