How Can an Energy Audit Benefit You as a Homeowner?

What Affects Energy Audit Costs?
Energy audit costs depend on several factors, helping homeowners plan their budget and select the right service level.
Home Size and Its Influence on Pricing
The size of your home plays a big role in determining audit costs. Larger homes take more time and resources, which drives up the price.
Complexity of the Audit
The type of audit you choose also affects the price.
- Basic visual inspections (Level 1): $100–$250
- Detailed evaluations with diagnostics (Level 2): $250–$650
- Advanced testing (Level 3): Over $650
Additional tools like blower door testing and infrared imaging can increase costs at some companies. At Green Leaf Energy, both are included in our Home Diagnostic Energy Audit, from $299.
Local Regulations and Incentives
In some areas, audits must comply with local conservation rules, which can add to the cost. However, local utility programs may offer rebates on upgrades an audit identifies. Being aware of these factors can help you plan your budget and take advantage of any available financial incentives.
Next, let’s look at typical price ranges for energy audits and what additional services might be offered.
Breaking Down Energy Audit Costs
Typical Price Ranges for Audits
Prices vary depending on the depth of the service. Here’s a quick breakdown:
