How Much Does It Cost to Install a Generac Generator?


The Average Cost of Installing a Generator

The average cost of installing a home backup generator for your home varies depending on its size. Most average installations will cost between $2,500 and $1,000 before adding in fuel costs and maintenance feesThe size of the generator you choose will largely depend on the amount of power you need to cover all the appliances and systems in your home. Larger generators may have a higher initial cost, but they frequently pay for themselves over time by avoiding large repair bills caused by power outages. On the other hand, a more significant backup home generator can be more costly to install and could also require more space than some homes have availableInstalling smaller models also means deciding which appliances and systems are most important during a power outageAdditionally, smaller models may not be able to handle the amount of load that bigger units can supply and may become overtaxed if all devices are turned on at onceInstallation costs must also be considered when deciding the number of outlets required and how much power each outlet needsAdditionally, additional expenses such as having an appropriate fuel storage tank (whether permanent or portable) Fuel lines, running conduit for wiring, and other elements must be included in the overall cost estimate for installing a whole house generatorWhen deciding what generator size is necessary for your home, weigh all factors of cost, convenience, and safety to ensure you select the best option for your needsThe following section will discuss determining the appropriate generator-size House.
When purchasing and installing a Generac generator, one of the most critical decisions is what size of the generator to make. The size of your Generac generator will depend on how many appliances and items around your home you want to power in the event of a power outage. Generally, a whole house unit between 8,000 and 20,000 watts for a medium-sized home would be an appropriate size. However, it is also essential to think about any large appliances you may have, such as an air conditioner, refrigerator, microwave, and well pump. You’ll likely need a more significant whole-house unit with more power for these types of items, given that these types of appliances typically require more energy to run. This means opting for somewhere between 28,000 and 48,000 watts for larger homes. Every home will have different information because of factors for the home. Building codes, utility grid fuel types, and generator sizes will differ for every home. When assessing the appropriate size for your home, consider which items inside and outside are essential for a power outage or blackout. Once you know the answer to this question, you’ll easily be able to determine what type of Generac generator best suits your needs in size and budget.

Why is Working with a Professional Important?

When it is finally time to decide on a generator and its installation, it can be challenging to determine whether to work with a professional. Working with pros comes at an additional cost, but some significant benefits may make this cost worthwhile for many people. Professionals come with years of experience and technical know-how that DIYers may not have. This level of expertise means the job can be completed safely and efficiently without worrying about problems arising due to inexperience. A professional installer will also usually offer a warranty on parts and labor. This gives homeowners peace of mind that their new generator will work as expected. On the other hand, some people argue that DIY installation can save money compared to working with a pro. In addition, DIYers may take pride in their accomplishments and enjoy learning the process along the way. A homeowner may have enough skill to complete the job themselves with the right tools and internet resources. However, they should be sure to weigh the risks thoroughly before starting. In summary, homeowners need to consider all aspects before deciding whether or not working with a professional makes sense for their particular situation. Both sides of the argument should be considered to make an informed decision.


How Are Professionals Insured and Licensed?

When installing a Generac generator, one of the most critical factors in considering the cost is insurance and licensing. Insured professionals can provide valuable protection and peace of mind that the job will be done correctly and safely. Licensed professionals may also be more reliable and offer more accountability. Let’s look at what else should be factored into your decision-making process. When it comes to choosing the right generator brand, what is the brand of generator you decided?
  • According to Lawes, the national average cost of a Generac generator installation is approximately $3,000-$13,000.
  • The total cost will vary based on how much power output you need and what type of features you decide to include in your installation.
  • It’s estimated that an average 7 kilowatt (7kW) home backup standby generator costs about $4,200 for just the unit and installation.

What is the Brand of Generator You Choose?

Choosing the right generator brand is crucial when determining your home’s power needs. But with such an array of options available in today’s market, it can be difficult to decide which one to choose. Between Generac, Cummins, Briggs & Stratton, and Kohler, it is essential to research the features and operational costs before deciding which generator is best for you and the installation cost. Generac is the leading household generator in America. They offer robust and reliable products that continue to generate consistent results at a comparatively low cost. They feature easy installation with prewired components, and their Quiet-Test Mode allows for quieter nighttime runtimes. Plus, their top-notch customer service is necessary. Cummins generators are also popular because they are built with heavy-duty construction and deliver consistent performance in extreme conditions, with state-of-the-art transfer switches and an innovative monitoring system. They provide optimal safety and excellent control over generator operations. Some argue that they provide added peace of mind with advanced warning notifications. Others say that they can be costlier upfront than other brands. Briggs & Stratton is another popular choice due to its affordability, making it a great option for those on a tight budget. Their easy operation makes them excellent options for even beginners in generator installation. However, some argue that their models have fewer features than competitors like Generac or Apex. Selecting the right generator brand depends on various factors, such as budget constraints—the size of your home or office space, local regulations, etc. Considering all these elements will help you choose the most suitable product. Now that you have considered what generator brand works best for you, let’s discuss what features you should look for in your next purchase.

What Features Should You Look for?

Consider your usage and the number of appliances or other devices (like lights, etc.) the generator will powerYou should also determine whether you will be using the generator regularly or if it needs to be able to respond quickly to power outages on an as-needed basis, depending on the applicationIn addition, you need to consider the type of fuel you will use to power the generator. Generator fuel can range from gasoline and propane to natural gas and solar options. Each has advantages, so you’ll want to evaluate each to decide which is best for you. Finally, you will want to consider the noise level of your chosen generator. Generac offers many models at different decibel levels, so it’s essential to find one that meets your needs while not disturbing anyone around itThese are just some features that should be considered when looking at a Generac generatorChoosing the suitable model and features for your needs can help ensure you get one that will last years.

How to Calculate the Total Wattage You Need for a Generator:
  1. Make a list of all the appliances and systems you want to power with your generator.
  2. Look up the running wattage for each item on your list. If you have the manuals for your appliances and systems, this information should be listed there. If not, you may be able to find the wattage information online.
  3. If any of the appliances on your list have motors (e.g. a refrigerator, air conditioner, or washing machine), you will need to calculate the starting wattage as well. To do this, use the formula: Running wattage (R) + Starting wattage (R x 3) = Total wattage needed. For example, if your refrigerator has a running wattage of 600 and a starting wattage of 1800 (600 x 3), you will need a total of 2400 watts to power it.
  4. Once you have the running wattage and starting wattage (if applicable) for all of the appliances and systems on your list, add them up to get the total wattage needed.
  5. Choose a generator that is rated for at least the total wattage needed. If you plan to use multiple appliances at the same time, you may want to choose a generator with a slightly higher wattage rating to ensure that you have enough power.

Here is an example of how to use this process to determine the total wattage needed for a generator:

  1. List of items to power: Refrigerator (running wattage 600, starting wattage 1800), microwave (running wattage 1200), television (running wattage 150), and a few light bulbs (running wattage 60 each).
  2. Running wattage for each item: Refrigerator 600, microwave 1200, television 150, light bulbs (60 x 4) 240.
  3. Starting wattage for the refrigerator: 600 + (600 x 3) = 2400.
  4. Total wattage needed: 600 + 1200 + 150 + 240 + 2400 = 4590 watts.
  5. Choose a generator that is rated for at least 4590 watts, or slightly higher if you plan to use multiple appliances at the same time.
