"Ron was excellent. I had a power-surge in my house, a scary situation. Happened on a Sunday Morning. Went on Angis list. Ron was the first to call, although he could not come that day (went to Pats game, who can blame him) he gave me some very helpful advise to start diagnosing the problem. As promise he did come Monday morning and was very thorough in evaluating the problem. We worked on a resolution together, set a plan in place, order parts together. He said he would be back on Thursday to replace main breaker, he actually called on Wednesday to say he can come a day early to fix the panel! Work is all done, very reasonable, very accommodating. So happy I connected with Ron, would HIGHLY recommend Ron for any electrical service/repair/install. I'm keeping his card, I'll be calling him again for any service I may need in the future! Thanks Ron!"

"Joseph did an excellent job installing my Tesla Wall Connector. He was on time, very professional, and completed the work quickly with great attention to detail. The installation looks clean and works perfectly. He also took the time to explain everything and made sure it was tested before leaving. I’m very satisfied with the service and highly recommend him for any electrical work."

Generator Install questions, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

Whole-house generators can last 20 to 40 years with normal operation and proper maintenance. If you look up the specifications for your generator, you may be able to find a lifespan rated in hours of operation. Life expectancy will vary depending on how often and for how long you use the generator each year. Choosing a fuel with low impact like natural gas or diesel can help generators last as long as possible.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

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.
