Selecting the Right Generator to Fit Your Needs

Let Commonwealth Power Group, Inc. ensure that you'll maintain power to the things you need most at all times. We'll walk you through the process of deciding which type of generator is best suited to your specific needs. Pricing can vary widely, depending on the amount of power you require. Some families have loved ones who require access to power at all times for vital medical equipment. Businesses need to have access to their point-of-sale systems whether the power is on or off.



Residential & Commercial Generators

Other considerations when purchasing a Chelmsford commercial generator or residential generator include ease of transport vs. needing a fixed unit, number of outlets required, amount of usage expected, noise tolerance, and run time required.

If you have a generator question or problem, Commonwealth Power Group, Inc. can help you devise an efficient and cost-effective solution. We provide generator services in Chelmsford and surrounding areas.



With natural disasters and extreme weather on the rise, more and more homeowners are investing in generators. Protect your family and your investments with an automatic generator. Whatever the reason for your generator needs, Commonwealth Power Group, Inc. can help by installing a generator that will provide power where you need it. What's more, our commercial generator services will keep your business out of the dark! As a business owner or manager, you know that loss of power equals loss of revenue. When the power goes out, every minute counts. We can keep your point of sale system up and running, even when the power is out.

Generator Installation

We install both Liquid propane and natural gas generators in Chelmsford and throughout the state of MA. Homeowners can choose to purchase a portable generator or a permanently installed generator, depending on their needs. Protecting your family can be simple and cost-effective with an automatic backup generator. Keep your vital appliances and equipment powered up, even when you are not home. The systems are also ideal for use in rental properties, where the homeowner may be out of town for extended periods. As a homeowner, you will save money on hotel bills if you can keep your home comfortable during power outages.
