"It was a pleasure to deal with this company. They are extremely knowledgeable in designing an electrical charging station in what was a difficult i situation. My breaker panel and garage were on opposite sides of my home. A solution was given at a reasonable price. I could not be happier. All work was done professionally with great attention to detail. If you are in need of electrical services, donâ t look any further. They are without a doubt, the best."

"Great service and Mark was professional at his work and explaining the problem. It wasn't the fan in the master bedroom that went bad, and he suspected the circuit GFI was tripped. We spent a little time to look for the failed GFI and was able to locate it in an odd place. The diagnostic price was a little expensive though."

"The electrician Kyle was professional , honest and affordable. He was punctual and courteous. I hired him for the wiring and panel upgrade but I requested he change my six GFCI outlets and check the older outlets. He checked the outlets that I was worried about -they were good. He did need to replace a different inside outlet and 2 of the 4 outside outlets. He was kind and explained why they needed to be replaced. One just was no longer working. The other 2 were not up to code actually were a fire hazard. I am female senior citizen grateful I hired Elevate Electric."

Generator Install questions, answered by experts

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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.
