"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

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. 

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
