SOME BRANDS WE OFFER INCLUDE:



Generator Installation
Having a residential generator installed at your home provides the peace of mind you need to weather the worst storms New England throws your way.
Generator Repairs
Is your generator struggling to run or completely malfunctioning? Contact us for prompt and expert repair service. We work on all brands and manufacturers including: Generac, Kohler, Briggs & Stratton, Cummins, and more.
Generator Maintenance
Routine maintenance of your generator is a must to ensure it performs well when needed. In fact, it's a requirement of most manufacturer's warranty programs.
How much does a standby generator cost?
For a 2,500-3,000 square foot home, if you were to choose something along the lines of essential circuits (heat, hot water, refrigerator, well pump, a few outlets and some lighting) a ball park estimate is around $12,000-$12,000 fully installed.
A system that would support the whole house would be closer to $14,000 – $15,000. This includes the generator accessories, site preparation and full electrical installation.
What brand should I buy?
We sell Kohler, Briggs and Stratton, Cummins and Generac. While some customers already have a brand preference, we are happy to make a recommendation based on your specific needs.
Is there a big difference in price depending on the brand?
Typically, the price difference between brands is minimal. The biggest factor in overall cost is the size of the generator, which is based on your power consumption needs.
Do you provide service?
Yes! We provide various levels of service depending on the customer’s specific needs and preferences. Learn more here.
How long does installation take?
Typically, we are able to schedule installation eight to ten weeks after our initial site visit.
Installation can take one to two full days depending on the generator size and location.
How quickly will my generator be installed?
We are typically scheduling installations about 8 to 10 weeks after receipt of deposit.
Where are you located?

Do you install generators in the winter?
Yes! We have heat mats that thaw the frozen ground and allow us to perform installs in cold weather.
