Trusted Home Energy Audit for Round Rock Homeowners
A Round Rock Home Energy Audit typically costs $250-$550 for a full assessment and takes 2-4 hours from arrival to written report. Most audits can be scheduled within 48 hours, and we run blower-door tests on every job so you see a hard number for how much air your home is losing before we recommend any work. Call (737) 259-7528 to book yours.
We’ve been sealing and insulating homes under The Haven Standard since 2016, and we’ve learned that most Round Rock homeowners who call us don’t actually know where their money is going. They know the upstairs bedroom stays hot in July, or their winter electric bill spiked after that renovation in Teravista, or their crawl space smells like mildew every spring. What they don’t know is whether they need more insulation, better air sealing, duct repair, or some combination that only shows up under pressure testing. That’s what a home energy audit is for. It’s not a sales pitch dressed up as science. It’s a documented diagnostic with before-and-after numbers you can verify yourself.
Round Rock’s climate doesn’t forgive guesswork. We’re in IECC Climate Zone 2, which means roughly 2,800 cooling degree days per year and enough humidity to make air leaks expensive in ways that don’t show up on a thermostat. Homes in Forest Creek built in the 2003-2008 boom often have top plates that were never sealed. The newer builds in Paloma Lake sometimes have spray foam that missed the rim joist entirely. In Brushy Creek and Wells Branch, we see a lot of fiberglass batts that were installed over can lights that leak conditioned air straight into the attic. These aren’t hypotheticals. They’re what we find, documented with photos and blower-door readings, on audits we perform every week.
Every audit we perform comes with a written price before any work starts, a Documented Photo Record, and if we do the work, before-and-after blower-door numbers so you can see the actual performance change. No exceptions. That’s Haven Standard Clause 1, and we’ve applied it to more than 9,000 homes since 2016.
What Our Home Energy Audit Service Includes
Blower Door Test
A blower-door test is a pressurization measurement that shows, in a single figure, how much conditioned air your building envelope is losing. We depressurize your home to -50 Pascals with a calibrated fan mounted in an exterior door, then measure the airflow required to maintain that pressure difference. The result is expressed in CFM50 - cubic feet per minute at -50 Pascals - and it’s the only way to know whether your air leaks are trivial or costing you hundreds per year. In Round Rock, we typically see readings between 2,500 and 6,000 CFM50 on homes built between 1995 and 2015, with the worst performers often feeling drafty despite having “adequate” insulation. We run this test at the start of every audit and again after any air-sealing work, so you have a verified number for the improvement.

Thermal Imaging Inspection
Thermal imaging with a FLIR infrared camera lets us see temperature differences across walls, ceilings, and floors that your eyes can’t detect. During a Round Rock audit, we use this after the blower door has been running for 15-20 minutes, because the pressure difference pulls conditioned air through leaks and makes them visible as cold or hot spots on the thermal image. We’ve found missing insulation behind knee walls in Mayfield Ranch, air bypasses around chimney chases in Behrens Ranch, and duct leaks in soffits that the homeowner had been chasing with HVAC contractors for two years. The images go into your Documented Photo Record with annotations explaining what you’re looking at, so you can review them with any contractor or verify our findings yourself.

Insulation Inspection
We inspect every accessible insulation surface in your home: attic floor, knee walls, rim joists, crawl space walls, and any exposed ductwork in unconditioned spaces. We’re not just checking depth, though we do measure that with a ruled probe and compare it to the R-value marked on your original batt or loose-fill. We’re looking for installation quality - compression, gaps, moisture staining, and the critical detail of whether the insulation was installed before or after air sealing. In Round Rock, we regularly find blown-in fiberglass in Longshore Farms homes that was added over unsealed top plates, which means the insulation is filtering air rather than stopping it. We document current R-values, identify deficiencies, and note whether removal and replacement is more cost-effective than topping off. Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, and other manufacturers, so our recommendations aren’t tied to any proprietary product.

Duct Leakage Test
A duct leakage test pressurizes your HVAC duct system to 25 Pascals and measures how much air escapes into unconditioned spaces like your attic or crawl space. In Texas, this matters more than most homeowners realize: leaky return ducts pull 140°F attic air into your system in August, and leaky supply ducts waste the cooling you already paid for. We use a Duct Blaster or calibrated fan with registers sealed to isolate the ductwork from the house envelope. In Round Rock homes with flex duct runs through vented attics, we commonly find 15-30% leakage to outside, which can turn a 16 SEER system into something closer to 11 SEER in practice. The test takes about 45 minutes, and the results go into your written report with specific recommendations for sealing, replacement, or rerouting.

Brands We Service for Home Energy Audit

We’ve worked with insulation and building envelope materials from Johns Manville, Knauf, and Rockwool on hundreds of Round Rock homes. With Johns Manville, we regularly assess their Spider blown-in fiberglass systems in attics where the original batts have settled below the top plate, and we know how their formaldehyde-free formulations perform in our humid summers. Knauf’s EcoSeal water-based elastomeric sealant is something we specify when we’re air-sealing before blowing in their Jet Stream Ultra loose-fill, because the combination gives us predictable blower-door results we can stand behind. Rockwool’s stone wool batts come up often in fire-blocking applications and interior wall soundproofing jobs in Round Rock’s newer builds, and we inspect their compression fit and vapor permeability when we’re called in after a failed inspection.
Whether your home was originally insulated with CertainTeed, Owens Corning, or any other manufacturer, our audit process is the same: measure what’s there, identify what’s failing, and recommend what will actually perform. We don’t have exclusive relationships with any brand, and we don’t get spiffs for specifying one product over another. The written scope you receive before any work starts lists materials by manufacturer and performance spec, not marketing name.
Signs You Need Home Energy Audit Right Now
- Your upstairs rooms stay 5-10°F warmer than the thermostat setting in summer. This isn’t normal in a properly sealed and insulated home. In Round Rock, we see this most often in two-story homes where the attic floor was insulated but the top plates and penetrations were never sealed, creating a thermal bypass that dumps heat into the second-floor ceiling. An audit with blower-door testing and thermal imaging will pinpoint exactly where the air is moving.
- Your electric bill spikes every July and August despite no change in thermostat setting. Austin Energy and Oncor customers in Round Rock often call us after seeing summer bills jump $80-$150 over spring baselines. Sometimes it’s duct leakage pulling attic air into the return. Sometimes it’s insulation that was displaced by a rodent or a cable installer. Sometimes it’s a failing radiant barrier that was installed reflective-side-down. The audit separates these causes so you’re not guessing with a contractor who only sells one solution.
- You feel drafts near outlets, baseboards, or interior walls even with doors and windows closed. These aren’t “just how old houses are.” In neighborhoods like Old Town Round Rock and Mays Street, we find balloon framing and unsealed plumbing chases that connect the crawl space to the attic, creating a chimney effect that moves air through interior walls. A blower-door test with smoke pencil tracing will show you the path in real time.
- Your crawl space smells musty or your attic sheathing shows dark staining. Moisture problems in Round Rock’s humid climate usually trace to air leaks, not vapor barrier failures. Warm, humid outside air hits cool surfaces in your attic or crawl space, and the condensation feeds mold. We use thermal imaging to find the air source and hygrometers to measure the moisture load, then specify sealing and ventilation changes that address the cause, not just the symptom.
- You’re considering solar panels, a new HVAC system, or a home addition. Any major energy investment should start with a baseline. We’ve audited homes in La Frontera where the homeowner was quoted $18,000 for solar, only to find that $3,200 in air sealing and duct repair would cut their load by 30% first. Solar contractors don’t always tell you that. An audit gives you the data to size any system correctly and avoid overbuilding.
Our Home Energy Audit Process - Step by Step

- 1
Schedule and confirm. Call (737) 259-7528 and you’ll speak to a live person, not a voicemail loop. We confirm your address in Round Rock, ask about your specific concerns, and schedule a 2-4 hour window. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
- 2
Exterior and interior walkthrough. Your technician arrives in a marked vehicle, uniformed, and begins with a visual inspection of the home’s exterior envelope, roof penetrations, and foundation. Inside, we note the age of the HVAC system, the type and depth of visible insulation, and any recent renovations that may have disturbed the envelope. This context shapes what we prioritize during testing.
- 3
Blower-door test and thermal imaging. We set up the blower door, run the baseline test, and capture thermal images while the house is depressurized. In a typical Round Rock home, this takes 60-90 minutes. We show you the images on-site and explain what they mean, so you’re not waiting for a report to understand your home.
- 4
Duct leakage test and insulation inspection. If ductwork is accessible in the attic or crawl space, we seal the registers and run the Duct Blaster. We probe insulation depths, check for moisture damage, and photograph deficiencies. All findings go into your Documented Photo Record, which is included on every job, not available on request.
- 5
Written report and price. Within 24 hours, you receive a written report with blower-door and duct-leakage numbers, thermal images with annotations, a prioritized scope of recommended work, and a flat price for each item. No work starts without your written approval. If you bring us a competing quote, we’ll read it with you as a Free Second Opinion.
How Much Does Home Energy Audit Cost in Round Rock?
A full home energy audit in Round Rock typically runs $250-$400 for homes under 3,000 square feet, and $350-$550 for larger homes or those with multiple HVAC systems - see how much Home Energy Audit costs in detail. A standalone blower-door test with thermal imaging starts around $175-$250, while a duct leakage test added to a full audit is usually $75-$125. These are the ranges we see across Round Rock neighborhoods from Forest Creek to Paloma Lake to Old Town.
Several factors move the price within these ranges. Homes with conditioned crawl spaces or multiple attic accesses take longer to inspect thoroughly. Older homes in the Mays Street area often need more extensive thermal imaging to trace balloon-framing bypasses. If you’ve already had an energy audit within 12 months and want us to verify or dispute the findings, we price that as a second-opinion consultation, typically at the lower end of the range.
What’s included at every price level: the blower-door test, thermal imaging, insulation inspection, and a written report with documented photos. Duct leakage testing is quoted separately if your ductwork isn’t accessible or if you specifically want it excluded. What’s never included: pressure to buy anything. You get the report, you get the price for any recommended work, and you decide on your own timeline. The 365-Day Done Right Promise applies to any work you do choose to have us complete.
To avoid overpaying, watch out for “free” audits that are clearly lead-generation tools for insulation sales crews. A legitimate blower-door test requires $3,000-$5,000 in calibrated equipment and 90 minutes of technician time. If someone’s offering that for free, they’re making it back somewhere else, usually by finding problems that don’t exist or recommending products that don’t fit. Our price is flat, written, and due only if you proceed with the audit. If you don’t like what you hear, you owe nothing for the initial consultation call.

Frequently Asked Questions - Home Energy Audit in Round Rock

A home energy audit is a diagnostic assessment of your building envelope, insulation, and HVAC ductwork using calibrated testing equipment. We pressurize your home with a blower door, image it with infrared cameras, and measure duct leakage to find where conditioned air is escaping and where outside air is entering. You receive a written report with specific numbers, photos, and prioritized recommendations for improvement.
Most audits take 2-4 hours from arrival to completion, depending on home size and accessibility. A 2,000-square-foot ranch in Round Rock with a single attic access and exposed ductwork might take 2.5 hours. A 3,500-square-foot two-story with conditioned crawl space, multiple HVAC zones, and finished basement could take 4 hours. You don’t need to be present the entire time, but we prefer you stay for the blower-door setup and thermal image review so we can answer questions in real time.
A full Home Energy Audit - Pflugerville and Round Rock area audits typically costs $250-$550 depending on home size and testing scope, with most Round Rock homes falling in the $300-$400 range. Standalone blower-door testing with thermal imaging starts at $175. Duct leakage testing is $75-$125 when added to a full audit. Call (737) 259-7528 for an exact quote for your home - estimates are free, and the audit price is written before any work starts.
Yes. We inspect and assess all major insulation brands including CertainTeed’s fiberglass batts and loose-fill products, Knauf’s Jet Stream and EcoSeal systems, and Rockwool, Johns Manville, Owens Corning, and others. Our audit findings are based on performance measurements, not brand loyalty, and our written scope specifies materials by R-value and application, not marketing name.
We don’t treat energy audits as emergency services, but we do maintain same-day and next-day availability for homeowners facing urgent situations. These include pending real estate transactions with inspection deadlines, HVAC failures where the root cause is unknown, and health concerns related to suspected mold or moisture intrusion. Call (737) 259-7528 and we’ll fit you into the schedule if at all possible. A live person answers 24/7.
The audit itself is a diagnostic service, so it carries our standard 365-Day Done Right Promise on the accuracy of our findings and documentation. If we miss something that a subsequent contractor finds, or if our blower-door readings don’t hold up to independent verification, we make it right. Any repair or improvement work you choose to have us complete is also covered by the 365-Day Done Right Promise, backed by a written scope and written warranty delivered before anyone lifts a tool.
Close all windows and exterior doors at least 4 hours before our arrival, and avoid running exhaust fans or the dryer during that period. We need the house in its normal “closed up” state for accurate blower-door results. Make sure we can access the attic hatch, crawl space entry, electrical panel, and all HVAC equipment. If you have recent utility bills, leave them out; they’re useful for correlating our findings with your actual consumption. You don’t need to move furniture or clear closets - we work around your home as it normally lives.
