"Punctual and professional. All of the work was completed right on schedule. They upgraded my entire home and replaced electrical panel. Definitely hiring again; I have them scheduled to repair the sprinkler system electrical work and the fans in both my bathrooms. The cost was surprisingly affordable! I cannot recommend enough."

"I have only good things to say about the good staff Patrick and James and Anthony and Jean in the office. The problem was with the Generac trickle charger for the battery which starts the generator when the power goes off. Patrick tracked the cause of the problem and Anthony fixed it in short order after a small delay in getting a new part. Jean in the office kept me informed and is very pleasant to deal with. This group all seem eager to please.

"He was on-time, but was frustrated that there was no parking due to all the snow.  He was going to cancel, but we were able to find him a spot.  Initially he seemed a little annoyed with the circumstances, but ended up being really nice and helpful.  He had never installed a microwave before, so he was going through the directions along with me, but we got it up.  He patched up a hole we had, then a few shelves.  We ended up getting along really well, and he was kind enough to split his time within two visits, since we didn't have one of the items that we initially thought we would have. 
Overall it was a really good experience.  It was a rocky start, but after we got over the parking situation, he was professional, and really helpful with everything we needed from his end.
We were very happy with their service, thank you!

Generator Install questions, answered by experts

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

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.
