"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"I highly recommend Deary Electric. After finding them through Home Advisor, I spoke on the phone with Josh just a few minutes later. They arrived when he said and called ahead 30 minutes before he arrived. Once here, Josh and his partner were able to quickly figure out what the problem was and fixed it shortly thereafter. Cost was more than fair; money well spent. Will definitely call them for future work."

"He's been the best electrician I've ever dealt with. I was extremely impressed and shocked. not only did he do a phenomenal job, but it's immaculate. There is not a little bit of wire sitting standing anywhere. He cleaned up, he was lovely, he didn't talk much, but you know, he was very busy all day because our entire electrical panel had been blown out from that storm. This is the 1st time since July 4 that we have not been sitting in our house with the lights flashing on and off."

Generator Install questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.

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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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.
