How Do You Conduct an Energy Audit of Your Home? A Step-by-Step Guide (Kansas City Area)

If your home feels drafty in winter, humid in summer, or your heating and cooling system seems to run nonstop, there’s a good chance you’re losing energy through places you can’t easily see—air leaks, insulation gaps, and duct issues. That’s exactly what a home energy audit is designed to uncover.

Central Energy Audits is based in Kansas City and serves homes across Kansas and Missouri, helping homeowners pinpoint hidden energy losses with testing (not guesswork) and a clear plan to improve comfort and efficiency.

Below is a practical walkthrough of how a home energy audit is conducted—what to do before the visit, what happens during testing, and what you should receive afterward.

What an energy audit actually measures

A professional audit evaluates how your home performs as a system—your “building envelope” (walls, attic, windows, doors), insulation levels, and how air moves through the home and ductwork. Central Energy Audits describes audits as a thorough evaluation using tools like blower door testing, infrared scanning, and attic/crawl space inspections to identify inefficiencies and where improvements will make the biggest impact.

Step 1: Start with a quick homeowner pre-audit checklist

Before an auditor arrives, you can do a little prep to make the visit smoother and the findings more accurate:

• List comfort problems room-by-room (e.g., “back bedroom is always cold,” “bonus room gets stuffy,” “living room has drafts near windows”).

• Note moisture or odor issues, like musty smells or condensation on windows.

• Clear access to the attic hatch, crawl space entry, HVAC unit, and main return(s).

• Replace HVAC filters if they’re visibly clogged (a clogged filter can distort airflow and performance clues).

• If you have smart thermostats, jot down typical schedules and any trouble spots.

This helps the auditor focus quickly on what you’re experiencing—because the goal is not just “lower energy use,” but also a noticeably more comfortable home.

Step 2: Consultation and review of how your home uses energy

A good audit begins with a conversation. Central Energy Audits includes a consultation step where they review utility information and discuss comfort concerns.

During this phase, you can expect questions like:

• Which rooms feel uncomfortable, and when?

• Have you had recent HVAC changes or renovations?

• Do you notice drafts, dust, or uneven temperatures?

• Any history of ice dams, window condensation, or attic moisture?

This is where you tell the “story” of your home—then the testing verifies what’s actually happening.

Step 3: Blower door testing (finding air leaks you can’t see)

One of the core tools in a professional audit is the blower door test. Central Energy Audits explains that the blower door creates a controlled pressure difference to measure airtightness and pinpoint where unwanted airflow is occurring—essentially locating the leaks that let conditioned air escape (and outside air sneak in).

What this looks like in real life:

• A temporary fan is mounted in an exterior doorway.

• The home is pressurized or depressurized.

• The auditor checks common leakage areas: recessed lights, attic hatches, plumbing penetrations, fireplace surrounds, rim joists, and window/door frames.

Why it matters: air leaks don’t just waste energy—they can also pull in humidity, dust, and outdoor pollutants, and they make rooms harder to heat/cool evenly.

Step 4: Thermal imaging / infrared scanning (seeing hot/cold “patterns”)

An infrared camera scan helps reveal temperature differences in walls, ceilings, and floors. Central Energy Audits notes that infrared scanning can uncover insulation gaps, heat loss, and even potential moisture issues, providing visual proof of where inefficiencies are happening.

Thermal imaging is especially helpful for:

• Insulation that’s settled, missing, or poorly installed

• Hidden air leakage pathways

• Hot spots from duct losses or attic heat intrusion

• Suspicious areas that may indicate moisture (which can reduce insulation performance)

This is the “aha” moment for many homeowners because the problem areas show up clearly.

Step 5: Attic and crawl space inspection (insulation + ventilation + envelope)

Central Energy Audits includes an attic/crawl space inspection to assess insulation thickness/type, identify leaks within the thermal envelope, and evaluate ventilation.

In many homes, the attic is a major driver of comfort problems:

• Gaps at top plates or around penetrations leak air into/out of the living space.

• Insulation may be thin, uneven, or blocked by storage.

• Ventilation issues can trap heat and moisture, affecting both comfort and durability.

This step often reveals the “big wins” that can noticeably improve comfort.

Step 6: Advanced testing (often includes duct leakage + HVAC performance clues)

Beyond envelope testing, Central Energy Audits also references duct leakage testing and HVAC performance testing as part of diagnosing where energy is being lost and how systems can be optimized.

Leaky ducts can waste a surprising amount of conditioned air—especially if ducts run through attics, crawl spaces, or garages. Duct issues can also cause:

• rooms that never reach the set temperature

• higher humidity

• excess dust

• long HVAC run times

Step 7: Your custom report and “what to fix first” plan

An audit should end with a clear, prioritized roadmap. Central Energy Audits describes providing a custom report with a prioritized action plan and estimated savings.

A strong report typically includes:

• Key findings (where energy is leaking and why)

• Recommended fixes in priority order (highest impact first)

• Notes on safety/ventilation considerations

• Practical next steps (what to DIY vs. what to hire out)

Step 8: Rebate guidance and paperwork support

If rebates or incentives are available, you want someone who understands the process. Central Energy Audits notes they work with local utilities and include rebate navigation—filing paperwork so homeowners can access available savings.
