We’ve been sealing and insulating homes under The Haven Standard since 2016, and we’ve learned that most Schertz homeowners who call us don’t actually know where their conditioned air is going. They know the upstairs bedroom in their Elm Grove home won’t cool below 78 in July, or that their winter gas bill in Copper Ridge jumped $80 from the previous year, or that one corner of the living room in their Pecan Grove build always feels drafty. A home energy audit is how we answer those questions with numbers, not guesses. The blower-door test gives us a single figure for air leakage. Thermal imaging shows us exactly where insulation has settled, compressed, or never been installed at all. Duct leakage testing reveals whether your HVAC is heating your attic instead of your bedrooms. Every audit ends with a written report, prioritized recommendations, and a flat price for any work we propose. No work starts without that written price. That’s Haven Standard Clause 1.

What Our Home Energy Audit Service Includes

Blower Door Test

A blower-door test is a pressurization measurement that shows, in one number, how much conditioned air your building envelope is losing. We mount a calibrated fan in an exterior door, depressurize the house to a standard 50 Pascals, and read the airflow in CFM50 - cubic feet per minute at that pressure. In Schertz, we regularly see new construction homes in the 2,500-3,500 CFM50 range that should perform better, and pre-2000 homes in Selma and Converse that test above 5,000 CFM50, meaning they’re exchanging their entire indoor air volume with unconditioned outdoor air every few minutes. Our crew runs this test at the start of every audit and, if you hire us for air-sealing work, again at the end so you have before-and-after documentation of the actual change.

Thermal Imaging Inspection

We use FLIR infrared cameras to map surface temperatures across walls, ceilings, and duct runs, revealing insulation gaps, moisture intrusion, and thermal bridging that visual inspection misses. In Schertz’s climate - where summer attic temperatures regularly exceed 140°F - a missing section of attic insulation over a top plate or around a chimney chase shows up as a bright hotspot on the camera. We find this constantly in the older ranch homes near Schertz Parkway and in the newer builds around Passerine where rushed insulation contractors skipped air sealing entirely. The thermal images become part of your Documented Photo Record, included on every visit, so you can see what we saw without climbing into your own attic.

Insulation Inspection

We measure existing insulation depth, check for proper placement, identify compression or water damage, and note whether vapor barriers are correctly positioned. Schertz sits in IECC Climate Zone 2, where the code minimum for attic insulation is R-30, but we frequently find attics in Live Oak and Windcrest with R-19 or less, often installed unevenly with bare spots over hallways and bathrooms where crews worked around ductwork. We also check for the reverse problem: insulation blown over unsealed can lights or top plates, which traps moisture and creates a pathway for attic air into living spaces. Our inspection tells you what’s there, what’s missing, and what sequence the fix should follow - sealed first, then insulated, always in that order.

Duct Leakage Test

A duct leakage test pressurizes your HVAC duct system and measures how much air escapes into unconditioned spaces like attics, crawl spaces, or wall cavities. In Schertz, where flexible ductwork is common in homes built from the 1980s through the 2000s, we regularly find 20-35% total duct leakage - meaning nearly a third of the air your compressor works to cool is dumped into your attic. We seal accessible duct connections with mastic and proper mechanical fasteners, then retest to verify the reduction. If your ducts are inaccessible or deteriorated, we’ll show you the thermal images and the leakage numbers so you can make an informed decision about repair versus replacement.

Brands We Service for Home Energy Audit

We’ve worked with insulation and air-sealing materials from Owens Corning, Icynene, and GreenFiber across thousands of Schertz-area homes, and we understand how each product performs in our specific climate. Owens Corning fiberglass batts and blown-in systems are common in the production builds throughout Cibolo and Universal City; we know how to spot installation defects like faced batts installed backward or blown-in settled below labeled depth. Icynene open-cell spray foam requires precise mixing ratios and substrate temperatures to perform as specified, and we’ve documented enough jobs to recognize when previous contractors applied it too thin or over wet surfaces. GreenFiber cellulose, treated with borate for fire and pest resistance, performs well in Schertz’s humidity when installed with proper ventilation - but we’ve also pulled saturated, mold-compromised cellulose from attics where roof leaks went unaddressed.

Whether your home was built with Owens Corning, Icynene, GreenFiber, or any other make of insulation, we can assess its current condition and recommend what’s actually needed. We don’t push proprietary products and we don’t have exclusive arrangements with any manufacturer. Our recommendations are based on what your audit numbers show, not on what’s moving fastest from the distributor.

Signs You Need Home Energy Audit Right Now

• Your upstairs rooms stay 8-12°F warmer than the thermostat setting in summer. This isn’t normal. In Schertz’s climate, a properly sealed and insulated envelope should maintain 2-3°F variation between floors. When the gap widens, it usually means attic air is leaking into ceiling cavities, ductwork is losing cooled air in the attic, or insulation has settled below effective levels. We measure all three during a standard audit.
• Your energy bills spike every July and January despite no change in thermostat habits. We’ve audited homes in New Braunfels and Alamo Heights where summer cooling costs doubled over five years while the homeowners kept the same 76°F setting. The cause was cumulative duct leakage and attic air infiltration that forced the HVAC system to run longer cycles. The audit isolates whether the problem is the envelope, the ducts, or equipment sizing.
• You feel drafts near outlets, baseboards, or interior walls even with windows closed. These aren’t ghost drafts. They’re pressure-driven air leaks from the attic through top plates, electrical penetrations, and partition wall gaps. A blower-door test quantifies the total leakage; thermal imaging shows us the exact pathways so we don’t seal what doesn’t matter and miss what does.
• Your attic insulation looks uneven, discolored, or has visible footprints. Footprints mean someone walked through without proper plank paths, compressing insulation and reducing its R-value. Discoloration often indicates past roof leaks, rodent activity, or air leakage patterns that have filtered dust over years. Our inspection documents what’s salvageable and what needs removal before new work goes in.
• Your HVAC technician has suggested a larger unit or mentioned “the system is undersized.” Before you spend $6,000-$12,000 on upgraded equipment, find out whether your current unit is fighting a losing battle against duct leakage and envelope infiltration. We’ve seen 3-ton systems in Schertz performing like 2-ton systems because 30% of their output never reached living spaces. Sealing and insulating often restores capacity without replacing equipment.

Our Home Energy Audit Process - Step by Step

1. 1
   Schedule and confirm. Call (830) 402-5240 or text us. A live person answers 24/7. We’ll ask about your home’s age, square footage, specific comfort complaints, and recent energy bills. You’ll receive a written confirmation with your technician’s name and a text when they’re en route. Under Haven Standard: Arrive on schedule, you get a named technician.
2. 2
   Exterior and interior walkthrough. Your technician inspects the home’s exterior for visible gaps, foundation cracks, and roof condition, then walks the interior with you to document your specific concerns. We note the thermostat locations, room usage patterns, and any recent renovations that might have compromised the envelope.
3. 3
   Diagnostic testing. We run the blower-door test, thermal imaging scan, insulation depth measurements, and duct leakage test in sequence. The blower door goes first to establish baseline leakage; thermal imaging follows while the pressure differential is still active, making leaks more visible. Duct testing requires temporary sealing of registers, so we coordinate this to minimize disruption.
4. 4
   Review findings on-site. Before we pack up, we show you the thermal images, explain the blower-door number in context for your home size, and walk through the prioritized recommendations. You’ll see photos of problem areas on our tablet, not vague descriptions on a clipboard. This is when we deliver a written price for any proposed work - flat, itemized, with scope and warranty spelled out. No work starts without it.
5. 5
   Written report and documentation delivered. Within 24 hours, you receive your full audit report: blower-door and duct leakage numbers, thermal images with annotations, insulation inspection notes, and our recommended sequence of improvements. If you proceed with work, this becomes the baseline for your before-and-after documentation. Every job closes with a Documented Photo Record; on applicable jobs, before-and-after blower-door readings are provided so you can verify the air-sealing result.
