What Does an Energy Audit Consist Of?

An energy audit is a whole-home (or whole-building) checkup that measures how your property uses energy—and, more importantly, where it’s being wasted through hidden leaks, insulation gaps, duct losses, and HVAC inefficiencies. Instead of guessing why your home feels drafty or why some rooms won’t stay comfortable, an audit uses diagnostic testing to pinpoint the causes and lay out a clear plan to fix them.

For homeowners, builders, and property managers in the Kansas City metro, Central Energy Audits describes a proven, step-by-step process built around blower door testing, thermal/infrared imaging, duct leakage testing, and performance-based reporting, with additional support for certifications, documentation, and incentives where applicable.

Below is what a professional energy audit typically consists of—explained in a practical, easy-to-understand way.

1) A Consultation That Focuses on Your Comfort and Energy Goals

A quality audit starts with context. Central Energy Audits includes an initial consultation step where they review relevant information (like patterns in energy use and comfort complaints) so the testing is targeted, not generic.

This part often covers:

• Rooms that feel hotter/colder than the rest of the home

• Drafts, humidity issues, or uneven temperatures

• HVAC run time (systems that seem to run constantly)

• Recent upgrades (new windows, new HVAC, insulation work, remodels)

Why it matters: Testing is more useful when it’s guided by real symptoms. The audit should connect your lived experience to measurable building-science data.

2) Diagnostic Testing (The “Proof” Part of an Energy Audit)

This is the core of what an energy audit consists of: measuring performance with tools that can detect problems you can’t see.

Blower Door Test (Air Leakage & Airtightness)

A blower door test measures how “leaky” the home is by creating a controlled pressure difference and revealing where outside air is getting in. Central Energy Audits explains that blower door testing identifies uncontrolled air leakage and quantifies airtightness—key for comfort, efficiency, and (in some cases) code compliance.

During blower door testing, leakage commonly shows up around:

• Windows, doors, and baseboards

• Attics and crawlspaces

• Outlets, vents, and recessed lighting

• Plumbing and wiring penetrations

What you get from this step: a clear understanding of how much air leakage exists and where sealing efforts will matter most.

Infrared / Thermal Imaging (Insulation Gaps, Draft Paths, Moisture Clues)

Central Energy Audits also uses infrared/thermal imaging to detect temperature variations that signal energy loss, missing insulation, air leakage pathways, and even moisture signatures that may indicate a building-envelope issue.

Their thermal scan process includes scanning areas like:

• Exterior walls and rooflines

• Attic insulation and crawlspaces

• Windows, doors, and floor edges

• HVAC ducts and utility penetrations

This is one of the reasons a professional audit is so valuable: it turns “I think something’s wrong in that wall” into visual evidence that guides the next steps.

Attic / Crawlspace Inspection (Insulation + Ventilation + Air Leaks)

Beyond imaging, Central Energy Audits describes inspecting attic/crawlspace conditions—checking insulation installation, thickness, and type, identifying air leaks within the thermal envelope, and reviewing ventilation for performance.

This part of an audit matters because the attic and crawlspace are often where homes lose the most energy—especially when insulation is incomplete or air leaks are pulling conditioned air out of the living space.

Duct Leakage Testing / HVAC Distribution Checks

Even if your HVAC equipment is in good shape, leaky ductwork can waste a lot of heating/cooling before it ever reaches your rooms. Central Energy Audits’ audit process references duct leakage testing as part of the advanced testing phase, and their broader compliance/testing work also includes duct leakage measurement.

3) HVAC Load Calculations (Manual J, S, and D)

A complete energy audit isn’t only about finding leaks—it’s also about making sure your HVAC system matches the home.

Central Energy Audits includes HVAC load calculations as a formal step in their audit process. They perform Manual J, S, and D calculations to evaluate HVAC efficiency and recommend properly sized equipment and design.

In plain terms:

• Manual J estimates how much heating/cooling your home actually needs

• Manual S helps verify proper equipment sizing

• Manual D supports duct design and airflow planning

Why this is important: oversized or undersized systems can lead to comfort problems, higher run time, and inefficiency, even if the unit is “new.”

4) A Detailed Report With Prioritized Recommendations

A professional audit should end with a clear, written plan—not vague advice.

Central Energy Audits provides a report that includes prioritized recommendations and highlights energy savings potential (and in their process description, includes items like ROI estimates).

Based on the issues found, recommendations commonly point to:

• Air sealing targeted to the biggest leakage zones

• Insulation improvements (attic/crawlspace focus)

• Duct sealing or airflow corrections

• HVAC optimization based on performance and load calculations

This is where the audit becomes actionable: it tells you what to do first, what can wait, and what will likely make the biggest difference for comfort.

5) Rebate, Documentation, and Certification Support (When Applicable)

For many Kansas City–area projects—especially new construction, major renovations, or efficiency programs—documentation can matter almost as much as the testing.

Central Energy Audits describes support for rebates and paperwork navigation as part of their overall process, and they also note support for ENERGY STAR and tax incentive documentation where applicable.

They also outline that certain compliance-related inspections may include additional elements such as mechanical ventilation testing, alongside blower door testing, duct leakage measurement, and attic insulation assessment.

Bottom Line: What an Energy Audit Consists Of (Quick Recap)

A Central Energy Audits–style energy audit typically consists of:

• Consultation focused on comfort and energy goals

• Diagnostic testing: blower door + thermal/infrared imaging

• Attic/crawlspace inspection for insulation, air leaks, and ventilation

• Duct leakage measurement / distribution performance checks

• HVAC load calculations (Manual J, S, D)

• A written report with prioritized next steps

• Optional help with rebates, certifications, and documentation
