Trusted Home Energy Audit for Boerne Homeowners
A Home Energy Audit in Boerne typically costs $250-$550 for a comprehensive assessment and takes 2-4 hours to complete. Most audits can be scheduled within 48 hours, with same-day appointments available for urgent comfort or efficiency concerns. Call (830) 529-7780 to book a slot.
We’ve been sealing and insulating homes across the Texas Hill Country since 2016, and we’ve learned that most homeowners in Boerne don’t actually know where their conditioned air is escaping. The attic is usually the culprit, but the path it takes can be surprising: top plates pulling air from wall cavities, can lights acting like chimneys, duct boots separated from drywall by a half-inch gap that pulls 120-degree attic air into your living room every summer afternoon. Our home energy audit in Boerne finds these leaks with measured precision, not guesswork. Every audit includes a blower-door test, thermal imaging, and a written report with photos and prioritized recommendations. We don’t sell you insulation you don’t need, and we never recommend adding insulation over an unsealed attic floor. That’s not a sales tactic; it’s physics. Unsealed air leaks render new insulation nearly useless within a season or two.
Boerne’s climate puts particular stress on building envelopes. Summer attic temperatures in Kendall County regularly hit 140°F, and winter cold fronts can drop overnight lows below freezing for a week straight. Homes built during the 2005-2015 boom in neighborhoods like The Dominion of Boerne, Cordillera Ranch, and Boerne Stage Field often have the same problem: insulation that looks adequate on inspection but performs poorly because the air sealing was never done first. We’ve audited more than 9,000 homes since 2016, and the pattern is consistent. The good news is that measured air sealing, done before any insulation work, typically cuts air leakage by 30-50% in a single day.
What Our Home Energy Audit Service Includes
Blower Door Test
The blower-door test is a pressurization measurement that shows, in one number, how much air your building envelope is losing. We mount a calibrated fan in an exterior door, depressurize the house to 50 Pascals, and measure the airflow in CFM50 - cubic feet per minute at that standardized pressure. A typical 2,000-square-foot home in Boerne with moderate air leakage reads 3,000-4,500 CFM50; a well-sealed home of the same size reads 1,500-2,500. When we complete air sealing work, we run the test again and give you both numbers. Most homeowners in Fair Oaks Ranch and Scenic Oaks who’ve had this done tell us the before-and-after comparison is the most useful piece of documentation they received from any contractor. You need this test if your utility bills spike every summer despite reasonable thermostat settings, or if rooms on the north side of your house stay cold while south-facing rooms overheat. Topside Attic Insulation Boerne uses a Retrotec or Minneapolis Blower Door system, calibrated annually, and our technicians are trained to interpret results in the context of local construction practices and climate loads.
Thermal Imaging Inspection
Thermal imaging, or infrared thermography, visualizes surface temperature differences that indicate missing insulation, air leaks, or moisture intrusion. Our FLIR cameras detect temperature variations as small as 0.05°C, revealing problems invisible to the eye: a top plate in a Cordillera Ranch home leaking attic air down into a bedroom wall cavity, or a section of spray foam in a Timberwood Park attic that separated from the roof deck and left a convection channel. You need thermal imaging when you have persistent comfort complaints that don’t match your thermostat readings, or when you’re considering insulation replacement and want to verify what you’re actually dealing with first. In Boerne’s intense summer sun, we schedule thermal imaging for early morning or late evening when the temperature differential between conditioned space and attic is greatest, giving the clearest diagnostic images. Every thermal scan is saved to your documented photo record, with annotations explaining what each image shows.
Insulation Inspection
An insulation inspection measures depth, density, and coverage of existing material, identifies compression or settling, and spots areas where insulation was installed over unsealed penetrations. In Boerne, we commonly find fiberglass batts in attics that were installed to R-30 at construction but have compressed to R-19 or lower after 10-15 years of foot traffic, storage, and rodent activity. We also find blown-in cellulose in Bulverde homes that settled 20-30% below the labeled depth because the original installer didn’t account for settlement during the first year. You need this inspection before adding any new insulation, because layering new material over damaged or compressed old material traps moisture and reduces overall performance. Topside Attic Insulation Boerne uses a combination of depth probes, density sampling, and visual assessment of condition. We note brand and type where identifiable - Owens Corning, Johns Manville, Knauf, GreenFiber - and we tell you honestly whether what’s there can stay or needs removal. No surprises, no upsell.
Duct Leakage Test
The duct leakage test pressurizes your HVAC duct system and measures how much air escapes to unconditioned spaces - attic, crawl space, or wall cavities. We seal the registers, connect a calibrated fan to the air handler, and measure leakage at 25 Pascals, expressed as CFM25 or as a percentage of system airflow. In homes we’ve audited in Leon Valley and Castle Hills, duct leakage commonly runs 25-40% of total airflow, meaning a quarter to nearly half the air your AC produces never reaches your living space. You need this test if you have rooms that won’t cool evenly, if your AC runs constantly in summer, or if your ducts run through an unconditioned attic - which describes most Boerne homes built before 2020. Topside Attic Insulation Boerne uses a Duct Blaster system and follows RESNET testing protocols. We separate supply-side from return-side leakage so you know exactly where the problem is, and we provide repair recommendations with written pricing before any work begins.

Brands We Service for Home Energy Audit
We’ve worked with insulation and air-sealing materials from every major manufacturer, and our audit findings are independent of any brand preference. When we recommend Owens Corning products, it’s because their ProPink LooseFill system performs well in the deep, irregular joist cavities common in Hill Country attics, and because their published R-values hold up under our post-installation verification testing. We’ve specified Icynene open-cell spray foam for dozens of Boerne homes with complex rooflines or conditioned attic conversions, particularly in the older neighborhoods near Main Street where headroom is limited and every inch of R-value matters. Demilec’s Heatlok HFO High Lift has become our go-to for sealed crawl spaces in the Fair Oaks Ranch area, where soil moisture and occasional flooding make closed-cell foam the right choice for the rim joist and band joist areas.
Whether your home currently has Owens Corning batts, Icynene spray foam, Demilec closed-cell, GreenFiber cellulose, or any combination from a previous contractor, we can audit it, test it, and tell you exactly how it’s performing. Our recommendations are based on measured data from your specific home, not on supplier relationships or inventory levels. If a competing estimate specifies a brand we don’t typically stock, we’ll tell you why we agree or disagree with that choice, and we’ll provide a free second opinion on any written estimate you bring us.
Signs You Need Home Energy Audit Right Now
- Your summer electric bill exceeds $300 for a home under 3,000 square feet. In Boerne’s climate, that’s a strong indicator your building envelope is leaking conditioned air faster than your AC can replace it. We’ve audited homes in Cordillera Ranch with $450 July bills that dropped to $220 after measured air sealing and targeted insulation improvements, with blower-door numbers to prove the change.
- You have rooms that stay 5-10 degrees different from the thermostat setting. Temperature stratification across rooms isn’t normal; it’s a symptom of duct leakage, missing insulation, or thermal bypasses in the envelope. In Scenic Oaks, we regularly find master bedrooms over garages that were never properly air-sealed at the garage ceiling, pulling conditioned air into the garage every time the HVAC runs.
- Your attic insulation looks flat, patchy, or disturbed. Insulation that has been compressed by storage, damaged by moisture, or tunneled by rodents performs at a fraction of its rated R-value. A visual inspection from the attic hatch tells part of the story; our depth and density measurements tell the rest.
- You smell attic air in your living space during shoulder seasons. That musty, hot smell when the AC hasn’t run in a few hours means air is moving through your envelope by stack effect alone, pulling attic air down through can lights, electrical penetrations, and top plates. It’s also a sign that humidity and pollutants are migrating with that air.
- You’re considering solar panels or a new HVAC system. Both investments deliver diminished returns if your envelope leaks. We’ve seen homeowners in Timberwood Park install $25,000 solar arrays, then discover their home was losing 40% of conditioned air to the attic. Audit first, then size your mechanical systems and renewable generation to the actual load.
Our Home Energy Audit Process - Step by Step
- 1
Schedule and confirm. Call (830) 529-7780 or text us; a live person answers 24/7. We confirm your address in Boerne, Fair Oaks Ranch, Scenic Oaks, or surrounding areas, ask about your primary comfort concerns, and schedule a 2-4 hour window. You’ll receive a text when your technician is en route, with a photo and name - Haven Standard: Arrive on schedule, you get a named technician.
- 2
Interview and walkthrough. Your technician reviews your utility bills for the past 12 months if available, asks about specific problem rooms, and walks the exterior and interior with you to note construction details: age, additions, previous insulation work, known moisture issues. This context shapes what we test and how we interpret results.
- 3
Diagnostic testing. We perform the blower-door test first to establish baseline air leakage, then use thermal imaging to locate the largest leaks, inspect insulation depth and condition throughout the attic and any accessible walls, and run the duct leakage test if ductwork is accessible. Every test is documented with photos, readings, and timestamped notes.
- 4
Written findings and prioritized recommendations. Before we leave, you receive a written report with your blower-door number, thermal images with annotations, insulation measurements, duct leakage percentage if tested, and a prioritized list of improvements with flat pricing for each. This is Haven Standard Clause 1: written price, written scope, written warranty before anyone lifts a tool. No work starts without it.
- 5
Decision and scheduling. You keep the report whether or not you hire us. If you proceed, we schedule air sealing or insulation work and provide a 365-Day Done Right Promise on all completed work. If you want a second opinion on our recommendations or a competing quote, we provide that free - bring us any written estimate and we’ll review it with you line by line.
How Much Does Home Energy Audit Cost in Boerne?
A comprehensive home energy audit in Boerne runs $250-$550 depending on home size, accessibility, and which diagnostic tests are included. A focused blower-door test with thermal imaging for a single-family home under 2,500 square feet typically falls at the lower end, around $250-$350. Adding duct leakage testing, full attic insulation inspection with depth mapping, and written prioritization of envelope improvements pushes the range to $400-$550 for larger homes or those with complex HVAC configurations.
Several factors affect where your audit falls in this range. Homes over 4,000 square feet or with multiple HVAC zones require more testing time and additional equipment setup. Crawl space access in older Boerne homes near Main Street or in the historic district adds inspection time. Duct systems with more than 12 supply registers need extended leakage testing to isolate problem branches accurately. Homes with existing spray foam insulation, particularly Icynene or Demilec products, require careful thermal imaging interpretation because the material’s low thermal conductivity can mask air gaps behind it.
To avoid overpaying, ask any auditor what specific tests are included and whether the fee is applied to subsequent work. At Topside Attic Insulation Boerne, your full audit fee is credited toward any air sealing or insulation work you contract within 90 days. We don’t charge separately for the documented photo record - it’s included on every visit, every time. And we never recommend tests you don’t need; if your ducts are in conditioned space or your home is under 1,200 square feet with a simple envelope, we’ll tell you that a full duct leakage test may not be cost-effective.
What’s included in our free estimate? If you call (830) 529-7780, we’ll ask enough questions to give you a firm audit price range before we schedule, based on your square footage, home age, and known issues. No bait-and-switch, no “we’ll see when we get there.” Written price before any work starts, always.

Frequently Asked Questions - Home Energy Audit in Boerne
A home energy audit is a systematic diagnostic evaluation of your building envelope, insulation, and HVAC distribution system using calibrated testing equipment. The audit produces measured data - blower-door CFM50, duct leakage CFM25, thermal images, insulation depth readings - that reveals exactly where conditioned air is escaping and which improvements will deliver the best return. Every audit we perform in Boerne ends with a written report, prioritized recommendations, and flat pricing for any proposed work.
Most comprehensive audits take 2-4 hours depending on home size, accessibility, and which tests are performed. A focused blower-door and thermal imaging assessment for a 2,000-square-foot home in Boerne typically runs 2-2.5 hours. Adding full duct leakage testing, crawl space inspection, or multiple HVAC zones extends the time. We schedule a window, not a rushed appointment, because accurate testing can’t be hurried. Call (830) 529-7780 to check same-day availability.
