The Ultimate Guide to Whole House Generators

Whole house generators have become increasingly popular as homeowners seek reliable backup power solutions. From powering critical appliances during storms to ensuring the entire home runs seamlessly in a blackout, these generators are essential for modern living. In this guide, we’ll dive into the most important aspects of whole house generators, addressing common questions and key considerations, including costs, sizing, installation, and soundproofing.


What Is a Whole House Generator?

A whole house generator, also known as a standby generator, is a powerful backup system designed to supply electricity to your entire home during power outages. Unlike portable generators, whole house generators are permanently installed, typically connected to a natural gas or propane line, and automatically kick in during a power failure. They provide peace of mind by ensuring uninterrupted power to essential devices and systems, such as HVAC, refrigerators, and medical equipment.

  • Local labor rates

How Big of a Generator Do You Need to Run Your Whole House?

Another critical consideration is determining how big of a generator to run a whole house you might need. Generator size is measured in kilowatts (kW), which represents the unit’s power capacity. The right size depends on your home’s energy requirements.

For most homes:

  • A 22-25 kW generator is sufficient to power essential systems and appliances in a medium to large sized home.
  • Smaller homes with modest energy needs might only require a 10-15 kW generator.
  • Larger homes with extensive power demands may need a generator with a capacity of 30-50 kW or more.

To calculate your specific requirements, consider the wattage of appliances and systems you want to power. Scales Electrical Service offers professional assessments to help you select the appropriate generator size for your home.


What Size Generator Do I Need to Run My Whole House?

You may wonder, “What size generator do I need to run my whole house?” Here are the steps to determine the ideal generator size:

  1. List Essential Appliances: Identify appliances and systems you want to power during an outage. This might include your HVAC system, refrigerator, water heater, lighting, and electronics.
  2. Calculate Total Wattage: Add the wattage requirements of these appliances. For example, an HVAC system might use 4,000 watts, while a refrigerator uses around 1,000 watts.
  3. Account for Surge Power: Some appliances require extra power to start up. Ensure your generator can handle these surges.

For most homeowners, consulting a professional electrician or generator specialist, like those at Scales Electrical Service, is the easiest way to make an accurate calculation.
