Energy auditors send an estimate before the visit, often by email or phone after asking about the home or building. Clients usually compare a few auditors on price, certifications, and what tests are included. A clear quote that lists tests and deliverables separates a full audit from a cheap walkthrough.
When to use estimates: Use estimates to provide project quotes and get client approval before starting work. Once approved, convert your estimate to an invoice with one click to collect payment.

Clients often assume every audit includes blower door, duct testing, and infrared scanning. Listing them avoids disputes over missing tests.
Price is based on these details, so the quote should state them and note that changes may affect the fee.
Defines what the client receives, such as recommendations, estimated savings, photos, and a modeling summary, and when.
Testing may require access to the attic, crawlspace, and mechanical rooms, and appliances to be operable. A no-access fee is easier to enforce if it was in the quote.
Auditors may find gas leaks, carbon monoxide, or moisture problems. State that the audit is not a code inspection and clarify how safety findings are handled.
Clients who plan retrofits need to know the cost of a test-out and how long that price is held.
Prevents surprise charges for rural or out-of-area sites.

Typical US ranges. Rates vary by region, experience, and job size.
Offer a basic, standard, and comprehensive option with set prices. Clients can pick the level that fits their budget, and you avoid custom pricing for every inquiry.
A client seeking a rebate, a lender-required report, or help with high bills needs different deliverables. Confirm the purpose and price the report to match.
Thermal imaging, duct testing, combustion testing, and modeling can be listed as optional lines. Clients see the value and you get paid for the extra work.
Quotes should be valid for 30 days or so. Equipment, travel costs, and your schedule change, and an expiration protects your pricing.
You can give a range or tier price once you know the size, age, and systems in the home, but confirm it in writing. A written estimate listing the tests included protects both sides.
Residential estimates are usually free. For large commercial buildings that require a pre-visit review of plans or utility data, some auditors charge a small scoping fee or credit it toward the audit.
Include language that the fee covers the stated tests and that extra testing, such as added duct systems or additional combustion appliances, may be billed at an agreed rate. Get the client's approval before doing the extra work.
