Residential & Commercial Generators
What is the difference between an automatic air-cooled generator and an automatic liquid-cooled generator? (Guardian and Protector Models)

The engines! Air-cooled generators come with engines that use fans to force air across the engine for cooling, while liquid-cooled generators use enclosed radiator systems for cooling, similar to an automobile. Generally, liquid-cooled engines are used on larger kW generators due to the larger engines required for the higher power output.

What is a standby generator?

A standby generator, unlike the portable options, are installed outside of your home and are wired directly to your home’s electrical system. The units usually run on natural gas or propane and will automatically start as soon as any power outage is detected, which is ideal for if you aren’t home when the power goes out. An appealing feature of the standby generator is that when the power outage is over, the unit will shut off on its own.


While a standby generator costs more initially, they supply more reliable backup power and are quieter when on. Also, these units can power much more than what’s possible with the portable unit. If you opt for a standby generator, it’s imperative a licensed and qualified electrician install it since it will be wired into the home’s electrical system. To learn more about standby generators or to schedule installation, contact our team today.

Is the cost of installation included in the purchase of my generator? If not, how much does installation cost?

No, the cost of the Generac home backup generator does not include installation.

Every home is different, and so is every installation. The placement of the generator, the amount of materials required, and the installation of the natural gas or LP fuel source all make estimating installation costs unique.

What does a shining yellow LED light mean on the control panel of my generator?

This is a maintenance reminder light. You can reset the light by pressing the Enter key on the control panel. Service reminders include inspecting the battery, changing oil and filter, changing the air filter, inspect spark plugs, and change spark plugs.

Our Authorized Service technicians provide parts, service, and information on equipment, regardless of where it was purchased.

Why should I buy an automatic backup generator instead of a portable generator?
  • With an automatic backup generator properly installed outside, your home is protected from deadly carbon monoxide poisoning that is a much greater risk with portable generators.
  • Running on your home’s natural gas or LP fuel supply is less expensive to run than gasoline and sources such as natural gas do not need to be refilled.
  • They start automatically within seconds of a power outage, and eliminate the need to haul a portable generator outside or run extension cords!
  • They provide protection 24/7, whether you’re home or away, and they turn themselves off when utility power returns.
  • Our company offers the FLEET program to our customers that provides our team with information about your generator 24 hours a day. We will know before you, if your generator needs service. Contact us today to find out pricing and the benefits of FLEET!

What is the difference between maintenance and a warranty?
  • Just like your car, your equipment needs scheduled maintenance. From oil changes to simply cutting the shrubs that are too close to the exhaust, regular maintenance will increase the life of your generator and is needed for any possible warranty claims.
  • We like to explain the difference in this simple way: maintenance is like changing the oil or oil filter in your car or getting a tune-up and a warranty is like what your dealership offers with your car in terms of how long aspects of your car will be covered.
  • During scheduled maintenance our team will look for other areas of your generator that may need to be lubed or adjusted according to the age, use or temperatures of your area and season.
What maintenance contract programs do you offer?
  • We currently offer a variety of maintenance programs. We offer several maintenance contract options that you can choose at any time. We offer a 2-year contract that is a $50 cost savings and ask us about our MVP (Maintenance Value Plan). Regularly scheduled maintenance provides an added layer of service that is needed to protect your warranty.
  • Our company offers a FLEET program contract that provides 24/7 monitoring along with the Maintenance Value Plan (MVP) or ala carte.
What does it mean to be a licensed and insured dealer?

Approved by the American National Standards Institute (ANSI), the NEC is the most complete set of electrical Code requirements that govern electrical installations in the interest of safety for persons and property.
