THE BEST GENERATORS

We only carry the top brands with the best manufacturer warranties. Each generator is installed and serviced by our expert Colonial Generator installer team. Our focus is on providing the “best in class” generators with excellence in installation, service and maintenance.  Our engineers go through rigorous training and each installation is backed by our service guarantee and the manufacturers warranty.  From 7kW to 150kW we carry, install, service and monitor any size generator for home or business.

BUILT FOR THE LONG TERM.

Every generator we install has a commercial grade engine built to withstand extreme workloads over many years. This heavy duty equipment with basic routine maintenance will outlast the ownership of your home.  That’s why it’s a great investment and will increase your sense of well-being.

“Two years ago we lost power for 3 days. Last year all of my neighbors lost power we didn’t. Never again!.”

George Michaels, homeowner, Villanova, PA
“Pretty much everything I read about Colonial Generators was on the mark.  Simple contract, no heavy sell, installed in a day and it was easy.  I wish everything was this simple”

Susan Wallace, homeowner, Media, PA
“We lost power during most major storms and some minor.  I lost thousands of dollars of food, plus some appliances and several nights at a hotel.  It really adds up – this is a great investment in peace of mind.”

PROACTIVE MONITORING

We are the only installer that provides an in-house monitoring service for each of its generators which ensures that your generator will be in good operating condition as a storm approaches.
