Power Up Your Home: The Ultimate Guide to Whole Home Generators


Power outages can be a major inconvenience, causing disruptions to daily life and potentially costing homeowners thousands of dollars in damages. In recent years, extreme weather events and aging infrastructure have led to an increase in power outages across the United States. In fact, according to the U.S. Energy Information Administration, there were over 3,500 power outages reported in 2019 alone, affecting millions of people.

One way to protect your home and family from the inconvenience and potential dangers of power outages is by investing in a whole home generator. These powerful machines can provide backup power to your entire home, ensuring that you have electricity when you need it most. In this ultimate guide, we will explore everything you need to know about whole home Generators, including how they work, the different types available, and the benefits of having one in your home.

What is a Whole Home Generator?

A whole home generator, also known as a standby generator, is a backup power system that automatically turns on when your home experiences a power outage. Unlike portable generators, which require manual setup and fueling, whole home generators are permanently installed outside of your home and are connected to your home’s electrical system. This means that when the power goes out, the generator will automatically turn on and provide electricity to your entire home.

Whole home generators are powered by either natural gas or propane and can provide enough electricity to power essential appliances and systems in your home, such as lights, heating and cooling systems, refrigerators, and security systems. They are designed to provide seamless backup power, ensuring that your home and family are protected during a power outage.

How Do Whole Home Generators Work?

Whole home generators work by monitoring your home’s electrical system for any interruptions in power. When a power outage is detected, the generator will automatically turn on and begin supplying electricity to your home. Once power is restored, the generator will shut off and return to standby mode.

Whole home generators are equipped with an automatic transfer switch, which is responsible for monitoring the power supply and switching between utility power and generator power. This ensures that your home is never without power, even for a few seconds.

Most whole home generators also come with a self-diagnostic system that performs regular tests to ensure that the generator is functioning properly. This feature is especially useful for homeowners who may not use their generator frequently, as it ensures that the generator is ready to go when needed.

Types of Whole Home Generators

There are two main types of whole home generators: air-cooled and liquid-cooled. The type you choose will depend on your home’s size and power needs.

Air-Cooled Generators

Air-cooled generators are the most common type of whole home generator and are typically used for smaller homes or as a backup for essential systems in larger homes. These generators use fans to cool the engine and are less expensive than liquid-cooled generators. However, they are also less powerful and may not be able to provide enough electricity for larger homes or multiple appliances.

Liquid-Cooled Generators

Liquid-cooled generators are larger and more powerful than air-cooled generators, making them suitable for larger homes or those with higher power needs. These generators use a liquid cooling system, similar to a car engine, to keep the engine at a stable temperature. They are more expensive than air-cooled generators but are also more durable and can provide more power.

Benefits of Having a Whole Home Generator

Investing in a whole home generator can provide numerous benefits for homeowners, including:

  • Peace of mind: Knowing that your home and family are protected during a power outage can provide peace of mind, especially during severe weather events.
  • Convenience: Unlike portable generators, which require manual setup and fueling, whole home generators turn on automatically, providing convenience and ease of use.
  • Protection of essential systems: Whole home generators can provide backup power to essential systems in your home, such as heating and cooling, refrigerators, and security systems, ensuring that your home remains functional during a power outage.
  • Increased home value: Installing a whole home generator can increase the value of your home, making it a valuable investment for homeowners.
  • Cost savings: Power outages can result in costly damages, such as spoiled food, flooded basements, and damaged electronics. Having a whole home generator can help prevent these damages and save you money in the long run.

Choosing the Right Whole Home Generator for Your Home

When choosing a whole home generator, there are several factors to consider, including your home’s size, power needs, and budget. It is essential to consult with a professional to determine the right size and type of generator for your home. They can also help you choose a reputable brand and ensure that the installation is done correctly.

It is also important to consider the fuel source for your generator. Natural gas is the most common fuel source for whole home generators, as it is readily available in most areas and does not require refueling. However, if natural gas is not available in your area, propane is a suitable alternative.

Installation and Maintenance

Installing a whole home generator is not a DIY project and should be done by a licensed professional. They will ensure that the generator is installed correctly and meets all safety codes and regulations. It is also essential to have your generator regularly maintained by a professional to ensure that it is functioning properly and ready to go when needed.

Regular maintenance may include changing the oil, replacing filters, and testing the generator’s functionality. It is also important to keep the area around the generator clear of debris and vegetation to prevent any potential hazards.

Cost of Whole Home Generators

The cost of a whole home generator can vary depending on the size, type, and brand. On average, a whole home generator can cost anywhere from $5,000 to $15,000, including installation. While this may seem like a significant investment, the benefits and peace of mind it provides make it a worthwhile expense for many homeowners.

It is also important to consider the potential cost savings in the long run. As mentioned earlier, power outages can result in costly damages, which can far exceed the cost of a whole home generator.

Case Study: The Benefits of a Whole Home Generator

One example of the benefits of having a whole home generator is the case of the Smith family in Florida. The Smiths live in an area prone to hurricanes and have experienced several power outages in the past, resulting in spoiled food and damage to their home’s electrical system.</
