Home Energy Audit Guide: Save Money & Lower Insurance

Discover energy waste, reduce utility bills, and potentially qualify for home insurance discounts with a comprehensive energy audit.

## What Is a Home Energy Audit?

### Home Information

A home energy audit is a comprehensive assessment of your home's energy use that identifies where your home is losing energy and which improvements will save the most money. Beyond reducing utility bills, many energy-efficiency improvements can qualify you for home insurance discounts and increase your home's value.

Energy audits range from simple DIY walk-throughs to professional assessments using specialized equipment like blower doors and infrared cameras. Either approach helps you prioritize improvements that deliver the best return on investment.
