Whole House Generators: Your Comprehensive Guide to Costs, Options, and Installation

What are whole house generators and how do they work?

Whole house generators, also known as standby generators, are permanent backup power systems designed to automatically provide electricity to your entire home during a power outage. These generators are typically fueled by natural gas or propane and are connected directly to your home’s electrical system. When a power outage occurs, the generator’s automatic transfer switch detects the loss of utility power and seamlessly switches your home’s electrical supply to the generator within seconds.

What are the benefits of investing in a standby generator?

Investing in a standby generator offers numerous advantages for homeowners:

1. Continuous power supply: Maintain essential appliances, HVAC systems, and lighting during outages.

2. Increased home value: Standby generators can be an attractive feature for potential buyers.

3. Peace of mind: Protect your family and property during severe weather events or prolonged blackouts.

4. Convenience: Automatic operation eliminates the need for manual startup or refueling.

5. Protection of sensitive electronics: Prevent damage to computers and other devices from power surges.

What size generator do I need for my home?

Determining the right size generator for your home depends on several factors:

1. Total square footage of your home

2. Number and type of appliances you want to power

3. Electrical demands of essential systems (HVAC, water heater, etc.)

4. Local climate and typical power outage duration

Generally, whole house generators range from 7 kW to 38 kW for residential use. A professional assessment can help determine the most appropriate size for your specific needs.
