When it comes to ensuring your home has a reliable source of backup power, a built-in home generator is one of the best investments you can make. Whether you live in an area prone to power outages or simply want peace of mind, a built-in generator can keep your lights on, your appliances running, and your family safe during an emergency. In this guide, we’ll explore everything you need to know about built-in home generators, including the best options available, key features to look for, and tips for installation and maintenance.
What is a Built-In Home Generator?
A built-in home generator, also known as a standby generator, is a permanent backup power solution that is installed outside your home. Unlike portable generators, which require manual setup and fueling, built-in generators are connected directly to your home’s electrical system and fuel supply. They automatically turn on when the power goes out, providing uninterrupted electricity to your home.
Why Choose a Built-In Home Generator?
Built-in home generators offer several advantages over portable generators.
Here are some key reasons why they are the best choice for homeowners:
Automatic Operation: Built-in generators start automatically when the power goes out, so you don’t have to worry about manually starting them.
Whole-House Power: These generators can power your entire home, including major appliances, HVAC systems, and medical equipment.
Durability: Built-in generators are designed to withstand harsh weather conditions and provide reliable power for years.
Convenience: Once installed, built-in generators require minimal maintenance and are always ready to go.
Types of Built-In Home Generators
There are two main types of built-in home generators: air-cooled and liquid-cooled. Each type has its own advantages and is suited for different needs.
Air-Cooled Generators
Air-cooled generators are the most common type of built-in home generator. They use fans to cool the engine and are generally more affordable than liquid-cooled models. Air-cooled generators are ideal for smaller homes or those with moderate power needs.
Pros:
- Lower cost
- Easier to maintain
- Suitable for smaller homes
Cons:
- Louder operation
- Less efficient cooling
Liquid-Cooled Generators
Liquid-cooled generators use a coolant system, similar to a car’s engine, to keep the generator running at optimal temperatures. These generators are more powerful and are better suited for larger homes or those with higher power demands.
Pros:
- Quieter operation
- More efficient cooling
- Higher power output
Cons:
- Higher cost
- More complex maintenance
Key Features to Look for in a Built-In Home Generator
When choosing a built-in home generator, there are several key features to consider to ensure you get the best model for your needs.
Power Output
The power output of a generator is measured in kilowatts (kW). It’s important to choose a generator with enough power to meet your home’s needs. Consider the size of your home, the number of appliances you want to power, and any special requirements, such as medical equipment.
Fuel Type
Built-in home generators can run on different types of fuel, including natural gas, propane, and diesel. Each fuel type has its own advantages and disadvantages.
Natural Gas: Natural gas is a convenient and cost-effective fuel option, as it is supplied directly to your home. However, it may not be available in all areas.
Propane: Propane is stored in a tank on your property and is a reliable fuel source. It is more expensive than natural gas but is widely available.
Diesel: Diesel generators are highly efficient and provide a long runtime. However, diesel fuel can be more expensive and requires proper storage.
Transfer Switch
A transfer switch is a critical component of a built-in home generator. It automatically switches your home’s power supply from the utility grid to the generator when the power goes out. Make sure the generator you choose comes with a high-quality transfer switch.
Noise Level
Generators can be noisy, so it’s important to consider the noise level when choosing a model. Look for generators with low decibel (dB) ratings, especially if you live in a quiet neighborhood.
Warranty and Support
A good warranty and reliable customer support are essential when investing in a built-in home generator. Look for models that come with a comprehensive warranty and have a reputation for excellent customer service.

How to Choose the Right Size Generator for Your Home
Choosing the right size generator is crucial to ensure it can meet your home’s power needs. Here’s a step-by-step guide to help you determine the right size generator for your home.
Step 1: Calculate Your Home’s Power Needs
Start by making a list of all the appliances and systems you want to power during an outage. Include items like your refrigerator, HVAC system, lights, and any medical equipment. Note the wattage of each item.
Step 2: Add Up the Wattage
Add up the wattage of all the items on your list. This will give you the total wattage your generator needs to provide.
Step 3: Consider Starting Wattage
Some appliances, like refrigerators and air conditioners, require more power to start up than they do to run. Make sure to account for this starting wattage when choosing a generator.
Step 4: Choose a Generator with Adequate Power
Select a generator with a power output that meets or exceeds your total wattage needs. It’s better to choose a generator with slightly more power than you need to ensure it can handle any additional loads.
Installation and Maintenance Tips for Built-In Home Generators
Proper installation and maintenance are essential to ensure your built-in home generator operates reliably for years to come. Here are some tips to help you get started.
