Customers say: True professional

"Travis and his team do outstanding work! Brent, Nick and Aiden did the majority of the project. I can’t say enough about their professionalism, skills and timeliness. They are extremely hard working individuals who clearly take pride in the work they do for others. They put in a new panel and rewired our entire house built in 1902 -not an easy job- and added multiple ceiling lights, outlets and switches where none existed before. They were very clean, used drop cloths and repaired holes. There was minimal dust, so my mom could live in the house during the work- nothing like what other people described when they had similar work done by other companies. They answered questions and replaced switches quickly when we realized the original color we picked did not look right. They were respectful and timely and the entire process went quicker than we thought possible. Travis and Brent were available by phone/text if we had questions on days not working. Mom and I highly recommend hiring!"

"Frank and his team always arrived on time and were able to start the work the week I requested a quote. They answered my questions and helped me to make decisions about what needed to be done. Had numerous lights/ceiling fans installed, outlets changed, and a doorbell installed along with the utility boxes being redone among other things. I would hire them again."

"Paul was excellent to work with. I needed an exterior garage wired. He was prompt, clean and a great value. I am looking to do a service upgrade for an electric car charger and already have been in touch with Paul to preform the work. Great to have a go to electrician anytime I need work done!"

"Very patience and considerate. Advised me on which generator to get that best fit my needs and budget, assembled it, gave me a tutorial on how to use it, and installed the proper electrical system to accommodate. Will hire again!"

"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

"We had a great experience with Andrus. Tony came out before our Kohler generator installation to clean up our electrical panel and did an incredibly thorough job. Everything was left clean and organized. The generator installation itself went very smoothly. The team was professional, knowledgeable and respectful of our property, and everything was explained clearly along the way. We're very happy with the finished installation and feel much better knowing we're prepared for the next outage. Would definitely recommend Andrus!"

Generator Install questions, answered by experts

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.

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
