"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

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

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.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

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.
