The Importance of Whole-Home Generators


Power going out is frustrating, stressful, and sometimes dangerous for those with essential medical equipment that needs electricity. While many homeowners think about portable generators from retailers for power outages, whole-house systems are potentially the better fit. Whole-home generators can keep families safe and comfortable during extreme weather and prevent businesses from experiencing costly disruptions. 


Whole-home generators are an investment that helps many property owners. For example, keeping the power on can keep the refrigerator on, which prevents your food from spoiling. Some homeowners may only need their lights and appliances on, while others must have their entire home running as normal, requiring a larger size.


Common Types of Generators


When booking an installation appointment, you'll need to decide what type of generator you prefer. The most popular types include:


  • Inverter generators
  • Portable generators
  • Natural gas generators
  • Portable power stations


What Contributes to a Whole-House Generator's Cost?


How much does a whole-house generator cost? Several factors add up to the total cost of a generator, such as:


  • Generator size
  • Output capacity
  • Installation costs
  • Fuel source
  • Generator type
  • Permits (if applicable)


All these factors and more can affect the cost of your whole-home generator. It's up to you what qualities of a generator you deem most essential, but every home should have some type of generator in the event a storm causes an outage. You don't want to sit idle without power or warm food. 


A gas generator is one of the more affordable options, but it cannot power an entire home and is unsafe to use indoors. Meanwhile, a diesel generator also uses fossil fuels and needs frequent refills to keep running. As for solar generators, they don't consume any fuel, are safer, and pair with solar panels.


Average Costs of Whole-House Generators


The total cost of a whole-house generator can range anywhere from $1,000 to $20,000, depending on size, generator type, fuel needs, and more. Exploring your options with a professional and getting multiple installation quotes can help you make the best decision for your home power needs and budget. Solar generators are an excellent investment since you don't have to stress about fuel costs or maintaining the system.


Installation costs can range from $500 to over $3,000, but permits can add another $200 or so. Electrical labor and the installation of a transfer switch may also increase costs by several hundred dollars. After solar, natural gas is the cheapest fuel source, followed by propane, diesel, and gas.


DIY vs. Professional Whole-House Generator Installation


You might think that DIY installation will cut down on some costs for your whole-house generator. This may seem like a good idea to save money, but you could end up spending more on faulty installation. The entire process has several complex steps that only an experienced professional should complete.


Professional installation with insurance and warranties will guarantee a flawless installation. You may need permits, depending on your location, and you could waste a lot of time and money by tackling it yourself. Get the job done right with the help of a trained and licensed professional in your area.

5 Pro Tips to Keep Your Generator Running Smoothly in Thiensville, WI

January 10, 2026
Is it really possible to keep your generator running smoothly with just a few simple steps? Many people overlook essential maintenance, thinking it's too complicated or time-consuming. However, with the right approach, you can guarantee your generator operates efficiently for years. Discover the five pro tips that can make all the difference in your generator's performance and longevity. Regular Maintenance Checks Regular maintenance checks are essential for keeping your generator running smoothly and efficiently. You should inspect your generator at least once a month to guarantee all components are in good working order. Start by checking the oil level and topping it off if necessary. Look for any signs of leaks or corrosion, as these can lead to bigger issues down the line. Don't forget to clean or replace the air filter to maintain peak airflow. Additionally, test the battery and connections, confirming they're secure and free from corrosion. Running your generator briefly every month can also help keep it in shape, allowing you to listen for unusual sounds. It's crucial to ensure that your generator undergoes preventative maintenance to avoid harmful issues such as carbon monoxide emissions. If you notice anything off, it's best to consult a professional. By staying proactive with maintenance, you'll help guarantee your generator is ready to perform when you need it most.  Keep Fuel Fresh and Stable To guarantee your generator operates efficiently, it's crucial to keep the fuel fresh and stable. Old or contaminated fuel can lead to performance issues and costly repairs. Start by using fuel stabilizers, which can help prolong the life of your gasoline or diesel. Make sure to store fuel in a clean, airtight container to prevent moisture and contaminants from entering. If you're not using your generator for a while, consider draining the fuel system or running it dry. This minimizes the risk of stale fuel sitting in the tank. Regularly check your fuel levels and replace old fuel every few months to maintain peak performance. Additionally, keep an eye on the fuel's appearance; if it looks cloudy or has a strange odor, it's time to replace it. Moreover, using backup generators ensures that you have a reliable power source during outages, which emphasizes the importance of maintaining your fuel. Inspect and Replace Filters While it might seem like a small task, inspecting and replacing your generator's filters is crucial for peak performance. Dirty filters can restrict airflow, causing your generator to work harder and potentially leading to overheating or mechanical failures. To keep your generator running efficiently, make it a habit to check the air and fuel filters every few months. If you notice any dirt, debris, or other buildup, it's time for a replacement. Always refer to your manufacturer's guidelines for the correct filter types and replacement intervals. When changing filters, verify you're using high-quality options to maximize your generator's efficiency and longevity. Additionally, regular emergency generator maintenance can help ensure that your generator remains in optimal working condition. Don't overlook this simple maintenance step, as it can save you from costly repairs down the line. Test Your Generator Monthly Testing your generator monthly guarantees it's ready to kick in when you need it the most. Regular testing helps identify any potential issues before they become major problems. Start by running your generator for about 30 minutes under a load to verify it operates smoothly. This not only checks the functionality but also keeps the battery charged and lubricates the engine. While it's running, listen for unusual sounds and watch for any warning lights. Make certain to check the fuel levels and look for leaks or signs of wear. After testing, turn the generator off and allow it to cool down. Document any findings or maintenance needed for future reference. Regular maintenance is crucial for standby generators and can help ensure your system is ready for emergencies. By making this a routine, you'll extend your generator's life and give yourself peace of mind, knowing it's ready when the power goes out. Don't skip this vital step; your preparedness relies on it! Store Your Generator Properly After you've tested your generator, it's important to store it properly to confirm it remains in good condition for future use. Begin by ensuring the generator is cool and clean. Remove any dirt or debris, as this can affect performance. Drain the fuel tank to prevent stale gasoline from clogging the carburetor; consider using a fuel stabilizer if you plan on storing it for an extended period. Choose a dry, well-ventilated area for storage, ideally indoors, to protect it from harsh weather conditions. Cover your generator with a breathable tarp to keep dust off without trapping moisture. Regularly check on it to confirm everything remains in good shape. Finally, keep all manuals and documentation handy, so you can easily refer to them when it's time to use your generator again. Following these steps will help you enjoy reliable power whenever you need it.
