We take pride in only recommending the right home generator for you. For such accuracy, though, we need to know exactly what we're dealing with. A free consultation at your residence with one of our skilled technicians will help us gather all the information we need to recommend the perfect generator for sale to you. Not to mention, it gives you the chance to get to know us! Our professional staff often provides calculations and estimates on the spot—and can schedule your installation right then and there.


Once we’ve established the perfect home generator for you, it’s simply a matter of installing it. Your power generator sits outside your home, just like an AC unit, and provides vital electrical power to your home in the event of a blackout. Depending on your specific needs assessed during the consultation, your generator will either power your entire home, or select appliances such as your kitchen amenities, air conditioning, heating, garage door, etc.

Contact us today for a free consultation and to learn more about what a residential generator can do for you and your home.

-Nancy A.

Just a note to let you know the employees that came ot our house were great. My husband is very ill & they took the time to go over everything they had done and answered all his questions with caring concern.

-Robuta A.

The whole process went smoothly, from the estimate to the generator pickup to the installation. The guys who did the install did a greay job, very professional, polite, and did a thorough job explaining the system.

-Jonathon V.

Your team that installed my 17kW was probably amongst the best example of what I would want representing my business. They were technically competent, experienced, efficient, pleasant, and overall good guys. They answered my technical questions with technical defendable answers - not personal opinions.

-Stephen S

I wanted to take a moment to express my sincerest appreciation for the quality work and professionalism we experienced when your employee came out to our home on Saturady to perform maintenance work on our Generac Home Generator.
