"Did a great job got everything done. Most of the power was back on day one. He had to come back day to for a little bit to finish up some stuff. And he also was able to add a 60 amp service outside for my hot tub."

Founded in 1994 by Al Powers, Powers Guaranteed Services (PGS) began by providing standby generator installation and service to the New England area. Over 28 years later, we have grown from a one-person operation to a company of over 70 valuable staff members and technicians who align on our core values of integrity, service, and communication, and we keep our word to our customers by consistently applying these values to each job we perform. PGS proudly employs licensed electricians, gas fitters, and EGSA-Certified generator service technicians (a certification which is earned by only a few generator technicians in the Northeast). Our factory-trained staff is continually expanding their knowledge to ensure we stay current on the latest developments within the industry.

"1) Installation with somewhat unique location and entrance into the house of electrical and gas lines. Electricians and Gas Pipefitter did excellent quality work, timely, neat, good steady pace throughout the day, including inevitable trouble-shooting. Site well-cleaned up afterwards. 2) & 3) Annual service agreements for both generator and minisplits always timely, well-executed, skilled personnel, and always polite."

Generator maintenance and repair, all small engines. Power outages are beyond your control, but how you prepare is not. You were smart to get a generator to protect your home, your family or your business.

Generator Install questions, answered by experts

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

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.
