FAQ

How does it work?

• Why should I buy an automatic backup generator instead of a portable generator?

  During a utility power outage, an automatic backup generator provides numerous advantages over a portable generator:

  • The American Red Cross recommends permanently installed backup generators as a safer way to provide backup power to a home than a portable generator.
  • With an automatic backup generator properly installed outside, your home is protected from deadly carbon monoxide poisoning, which is a much greater risk with portable generators.
  • Running on the home’s natural gas or LP fuel supply, it is less expensive to run than gasoline and does 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 throughout your home.
  • They provide protection 24/7, whether you’re home or away, and they turn themselves off when utility power returns, so there is no need to monitor the unit during an outage.

• What is an automatic backup generator?

  An automatic backup generator is a backup 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. See the “How It Works” video for more information.

• 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.

• How do I correctly size a generator for my home?

  The most logical way to determine your needs is to envision your home without power. 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 needs.

• Do the generators have to be maintained?

  Yes, simple maintenance is required. All generators require periodic oil and filter changes to ensure maximum performance for years of reliable service. Gen-Tech offers annual maintenance contracts for a worry-free ownership experience. Refer to the owner’s manual for routine maintenance procedures and schedules.

• What happens if the generator gets overloaded?

  Generac generators are equipped with overload protection. In the rare event of an overload, the generator’s circuit breaker will trip, disconnecting the unit from the load. Simply correct the overload and reset the breaker in the generator. For more information, please consult your owner’s manual or contact us.

• What's the right backup power solution for me?

  The most reliable source of power for extended or unpredictable power outages is a home backup generator. The generator, which in most cases is connected directly to a home’s natural gas line, has a constant supply of fuel and can operate through extended outages, keeping homes safe, lit and powered.

  For people concerned with a loss of natural gas supply during a storm, generators can be fueled by a dedicated LP tank as well.

  With this continuous fuel source, generators are much better able to face the unpredictability of dangerous, storm-prompted, or lengthy outages rather than a home battery, which relies on an external power source to recharge it after only a few hours of use.

• What are the most common reasons why homeowners invest in home backup generators?

  Heating and air conditioning are top concerns, along with running water and hot water. All of these items are high-load appliances and require a high capacity to start. These actions consume significant power and could quickly drain a battery.

• How much power output can a generator produce?

  The most popular Generac generator model produces 22kW, which is commonly installed to power the entire home, including all the most common appliances in a home, such as high-load central air conditioners, electric heaters, kitchen appliances, etc.

• What is the difference between a home backup generator and a home battery system?

  The prime difference is that a battery is meant to store power and a generator creates power. In a power outage, a generator can continuously produce power; a battery can only distribute what has been stored.

• How much is everything going to cost?

  Generac home backup generators are the most cost-effective on the market. Installation costs vary by system size, installation considerations, and local building codes. We recommend getting a free, in-home assessment to receive a customized quote for your home generator needs.

• What's involved in installing a home backup generator?

  Installing a home backup generator is an exciting time. Gen-Tech will prepare the installation site outside your home, place the generator, run the natural gas or LP fuel line, install the transfer switch, and make all of the necessary electrical connections. Once installed, will make sure that your backup generator runs properly and is ready for its first power outage.
