Generator FAQ's

1) What is an automatic backup generator?

An automatic backup generator is a back up electrical system that operates whether you are home or away. Within seconds of an outage, it automatically supplies power directly to your home's electrical circuit breaker box. After utility power returns, the generator shuts itself off and waits for the next outage. It operates on natural gas or liquid propane gas and sits outside just like a central air conditioning unit.

2) What size generator do I need for my home?

Every home owner's requirement is different. Your generator will be sized based on the electrical load it will be carrying. It all comes down to what you want to run during an outage. Some outages may be short in duration, while others could last for days or weeks. What would your family miss during an outage?
The very best way to understand your options and work within your budget is to schedule a free in-home assessment. During your consultation, you will receive the personalized attention and detailed evaluation you need to find a solution that works for your need.

Basic essential circuit coverage starts with the economically priced Generac PowerPact™ Series. Other systems are available to cover virtually any application:

· Essential Circuit Coverage - Generac takes the guesswork out of sizing by offering prepackaged Guardian Series generator systems. The generator is paired with a transfer switch containing a predetermined number of circuits based on the generator's kW power rating. Each circuit is directly connected to a matched circuit on the home's main circuit breaker panel, providing electricity to that specific appliance or area of the home.

· Managed Whole House Coverage - You can get more coverage with less generator, up to whole house coverage, by pairing a smaller generator with one of Generac's load shedding options. This creates a managed power solution where non-essential circuits are shed when the generator approaches maximum capacity. They are cycled back on when essential circuits no longer require power, so all circuits receive power at different times.

· Complete Whole House Coverage - Easily cover every circuit in your home by pairing one of Generac's larger kW units and the proper transfer switch to provide full coverage. No circuit is ever left uncovered, so every appliance is available every minute.

3) How loud is the generator?

The air-cooled generators are all about 66db's at 20 feet. What does this mean? It means you can have a regular conversation between two people standing next to a running air-cooled generator. Remember, Generac has been manufacturing generators for over 60 years; they are designed for residential neighborhoods.

4) Do I need a building permit?

Yes. In many cases, we have already completed a number of installations in your town or city and are already familiar with what your Building Department requires. We as your contractor will submit all necessary permits and drawings to your local building department. We will provide assistance with filing the zoning application, if a zoning application is required in your township.

5) How much service does a generator need once it is installed?

All generators require periodic maintenance, such as oil and filter changes to ensure maximum performance for years of reliable service. In most cases, we recommend a generator service is performed annually.

6) How long will my new generator last?

The average life expectancy of a standby generator is around 15 years of operation under normal emergency standby conditions.

7) How big and how heavy are these generators?

Most air-cooled residential generators are around 350-400lbs.

8) What fuel supply do I need to run one of your generators?

Generac home standby generators can be fueled by either Natural Gas or Propane vapor. Portable generators are designed to be fueled by gasoline only.

9) How much does it cost a month to run the generator when it runs for 10
minutes a week?

Depending on the price of natural gas, it shouldn't cost more than $4 or $5 per month to run the unit in exercise mode. During a power outage, under 50% load expect to pay around $20-$30/day for gas usage. A lot cheaper than a hotel room or spoiled food!

10) How big should my liquid propane (LP) tank be?

We recommend at least 250 gallons for our Generac automatic standby units. However, every home is different, and so is every installation and set-up. We recommend that you get a free in-home assessment to help determine the best set up for your needs. In-Home Assessments are available to you at no charge, with no obligation, and no pressure.

11) What is the difference between an automatic air-cooled generator and an
automatic liquid-cooled generator?

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.
