This is how we work

As a provider for residential and commercial/industrial customers for more than 30 years, we offer superior service which is manifest in our all of our products and staff members. We deliver the best warranties, factory support, parts availability, reliability and quality workmanship.
"We provide a free assessment, and after determining the right automatic home or commercial standby generator for your backup power needs to protect you from the negative effects of a utility power outage."

We size up which generator will fit a client’s needs. We look at:

• size of the home or commercial property.
• best location for the generator
• opportunity to connect with natural gas or propane
• to be as close as possible to electrical and gas meters

We also help you consider what appliances the customer wants to be backed up to the generator which determines the kilowatt usage. This also guides us in selecting the generator that will provide the proper amount of power. Our units can deliver 9 kw – 150 kw.

"It’s very important that everybody involved in a generator installation is licensed, certified, and insured. Doing so protects you as the homeowner, it protects your homeowners insurance, and it protects us as the contractor."

We pull permits according to your jurisdiction’s rules. We also plan for the concrete pad on which the generator will sit. Installation requires 1 day and can be completed within 8 hours.

We work with clients’ schedules to arrange for convenient delivery.

We fill the unit with oil needed for operation during a power failure. This can last 5-7 days, depending on the amount of usage.

"Power Failure Simulation a simulated  power failure and ensures that your entire backup power system is operating flawlessly"

To confirm the generator is adequately fueled and properly wired, we will simulate a power outage to test your system’s responsiveness and ensure that all loads are provided ample power the next time an outage occurs.

As the proud new owner of an automatic home or commercial standby generator, we will go over the completed installation and future servicing of the generator to keep it running in peak performance for future outages.

"Any generator set used for emergency source of power should always have a periodic service and maintenance performed. We make setting up a planned maintenance schedule easy and cost-effective..."

Our annual maintenance plan includes once a year visits when we change the oil and the oil filter, check all of the components and update the software.

As an authorized Generac dealer, our staff is highly trained with their products and have 20 years of experience servicing our customers.
