#1 in Emergency Generators

At Colonial Generators we only focus on one thing – Generators. We carry only the best generators from Cummins, Generac, Briggs & Stratton and Kohler.  Every Colonial Generator is meticulously quality-tested from start to finish. Our quality standards continue to our installation, service and monitoring departments.  Excellence in training and customer service are a part of our core competence. From 7kW to 150kW we carry, install, service and monitor any size generator.

We sell generators all over the U.S. but we install any size generator for home or business throughout the Mid Atlantic.  We have locations at 473 S. Henderson Rd, King of Prussia, PA 19406 and our new location at 202 Milton Street, Dedham, MA 02026.  From these locations our crew can install and service Pennsylvania, New Jersey, Maryland, DC, Virginia, Connecticut, Vermont, Massachusetts, New York, New Hampshire and Rhode Island.

Colonial makes the process of purchasing, designing, installing and monitoring simple and easy.
