Trusted Home Energy Audit for Leander Homeowners
A Home Energy Audit in Leander typically costs $350-$650 for a full diagnostic package and takes 2-4 hours to complete. Most homeowners schedule one after noticing uneven temperatures between rooms or utility bills climbing faster than neighbors in similar homes. Call (737) 252-7159 and we’ll book a slot this week, often with next-day availability in Leander and nearby Cedar Park.
We’ve been sealing and insulating homes under The Haven Standard since 2016, and we’ve learned that guessing wastes money. A proper audit tells you exactly where conditioned air is escaping and in what order to fix it. In Leander’s Hill Country climate, where summer attic temperatures hit 140°F and winter cold fronts drop overnight lows into the 20s, that sequence matters. We’ve completed 9,000+ jobs, every one starting with a written price and ending with a documented record. Our blower-door technicians are background-checked and uniformed, and a live person answers our phones 24/7. No voicemail loops. No callback windows measured in business days.
What Our Home Energy Audit Service Includes
Blower Door Test
A blower-door test is a pressurization reading that shows, in one number, how much 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 cubic feet of air moving through the fan per minute at that pressure - your CFM50 score. In Leander, we regularly see pre-audit readings of 3,500-5,000 CFM50 in homes built between 2005 and 2015, before any sealing work. After we complete air sealing of top plates, can lights, and penetrations, we run the test again and publish both numbers in your job record. You leave with documentation showing the exact performance change you paid for.
Thermal Imaging Inspection
Our FLIR thermal cameras reveal surface temperature differences invisible to the eye, mapping insulation gaps, air leaks, and moisture intrusion across walls, ceilings, and floors. We scan during the audit while the blower door is running, which exaggerates leakage paths and makes them unmistakable on camera. In Leander neighborhoods like Crystal Falls and Travisso, where stucco exteriors and complex rooflines hide thermal bridges, this step often reveals missing insulation behind knee walls or unsealed garage-ceiling penetrations that the homeowner never suspected. Every thermal image is saved to your Documented Photo Record with annotations explaining what you’re seeing.
Insulation Inspection
We measure existing insulation depth, check for compression and moisture damage, and identify areas where blown-in or batt insulation was installed without prior air sealing - a common defect we correct. In Leander’s newer subdivisions, we find fiberglass batts stuffed over leaky top plates, or cellulose blown onto attic floors with visible dust pumping through can-light gaps. We check for proper ventilation baffles, soffit clearance, and signs of rodent activity that compromise thermal performance. Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so we can recommend the right product for your specific assembly without proprietary lock-in.
Duct Leakage Test
A duct blaster pressurizes your HVAC duct system to measure leakage to the outside, quantifying how much conditioned air you’re dumping into the attic or crawl space instead of the living space. In Leander, where many homes have flex duct running through vented attics, we routinely find 20-35% total leakage - sometimes over 50% in systems with deteriorated tape or disconnected boots. We seal accessible leaks with mastic and proper mechanical fasteners, then retest. The before-and-after duct leakage numbers join your blower-door results in the written documentation. If your ducts need replacement beyond sealing, we’ll show you the photos and explain why, with a separate written price for that scope.

Brands We Service for Home Energy Audit
We’ve worked extensively with Owens Corning insulation systems, particularly their AttiCat blown-in fiberglass and ProCat professional loose-fill products common in Leander-area production homes built after 2010. We know the density specs and settling rates, and we can identify when an existing Owens Corning installation was done to manufacturer standard or shortcutted. Our crews also have deep experience with Icynene open-cell spray foam, including the specific expansion characteristics and vapor-profile considerations that matter in our hot-humid Texas climate. We’ve audited and corrected jobs where Icynene was applied too thin or without proper substrate preparation.
Demilec closed-cell foam and GreenFiber cellulose round out our regular material set. Demilec’s higher R-value per inch makes it appropriate for narrow cavities where space is limited, and we can spot the off-gassing and adhesion issues that indicate a botched application. GreenFiber’s recycled-content cellulose performs well in Leander’s older homes with irregular framing, though it demands meticulous air sealing first - exactly our sequencing. Whether your home has Owens Corning, Icynene, Demilec, GreenFiber, or any other make, we can audit it, interpret what we find, and recommend fixes with a written price before any work starts.
Before
AfterSigns You Need Home Energy Audit Right Now
- Your upstairs rooms stay 8-12°F hotter than downstairs in July. This isn’t normal for a properly sealed and insulated envelope. In Leander, where afternoon sun pounds west-facing second stories, the gap usually points to attic air leaks pulling conditioned air upward, inadequate insulation depth, or both. An audit pinpoints which factor dominates and in what order to address it.
- Your electric bill exceeds $0.14 per square foot in summer months. We’ve benchmarked hundreds of Leander homes; healthy envelopes with efficient HVAC run closer to $0.09-$0.11 per square foot. If you’re spending significantly more, you’re paying to condition air that’s escaping before you feel it.
- You feel drafts near outlets, baseboards, or can lights even with windows closed. These are telltale signs of pressure-driven leakage through the thermal boundary. In homes near Leander’s Brushy Creek and Cedar Park borders, where wind exposure is higher, the effect is more pronounced. The blower-door test quantifies this precisely.
- Your HVAC runs constantly but never reaches setpoint. This strains equipment and shortens lifespan. Often the system is sized correctly but the building loses conditioned air faster than the ducts can deliver it. An audit separates mechanical problems from envelope problems so you don’t replace a furnace that was never the issue.
- You’re considering solar panels or a new HVAC system. Both investments perform poorly on leaky homes. We’ve audited Leander properties where the homeowner was quoted $25,000 in solar capacity that would have been halved with proper air sealing and insulation. Fix the envelope first. The numbers prove it.
Our Home Energy Audit Process - Step by Step
- 1
Schedule and confirm. Call (737) 252-7159 or text us. A live person answers 24/7. We’ll ask about your home’s age, square footage, specific complaints, and any recent work. You’ll receive a confirmed appointment with a named technician and a text when they’re en route - Haven Standard: Arrive on schedule.
- 2
Walkthrough and interview. Your technician reviews your utility bills if available, notes comfort complaints room by room, and identifies any prior insulation or HVAC work. This context shapes where we focus diagnostic time. We also verify access to attic, crawl space, and electrical panel.
- 3
Diagnostic testing. We run the blower-door test first to establish baseline envelope leakage, then thermal imaging under depressurization to map leakage paths. We inspect insulation condition and measure depths, then duct-blaster test if ductwork is accessible. All readings are recorded in real time.
- 4
Findings review. We sit with you and show the thermal images, explain the blower-door and duct leakage numbers, and walk through the prioritized scope. Air sealing always precedes insulation in our recommendations - we will never quote insulation over an unsealed attic floor. You receive a written price with flat scope and written warranty before anyone lifts a tool.
- 5
Documentation delivery. Whether you proceed with work or not, you leave with a Documented Photo Record of everything we found, all diagnostic readings, and our written recommendations. If we perform air sealing, we run the blower-door test again and publish both numbers so you can verify the result.
How Much Does Home Energy Audit Cost in Leander?
A full home energy audit in Leander typically runs $350-$650 depending on home size, accessibility, and the depth of diagnostics you need. A focused blower-door test with thermal imaging for a 1,800-square-foot single-story home in a neighborhood like Mason Hills usually falls at the lower end, around $350-$425. Add the duct leakage test and full insulation inspection for a larger two-story in Travisso or Rough Hollow, and you’re looking at $525-$650. These are real ranges for real homes we’ve audited in Leander - not teaser rates that balloon on arrival.
Several factors move the price. Homes over 3,500 square feet require longer test times and more thermal imaging coverage. Multiple HVAC systems need separate duct blaster setups. Crawl space access that’s been sealed over by previous owners adds time. Attics with active rodent issues or buried junction boxes slow the inspection for safety. What doesn’t affect the price: sales pressure to buy additional services. Our audit fee is flat. If you choose to proceed with recommended work, the audit cost is credited toward your project.
To avoid overpaying, compare what’s actually included. Some Leander-area competitors advertise “$199 energy audits” that consist of a brief attic peek and a generic report. Ask whether they run a calibrated blower door, whether thermal imaging is performed under depressurization, whether duct leakage is tested, and whether you receive documented photos and written readings. If the answer is no, you’re paying for a sales pitch dressed in technical language. Under Haven Standard Clause 1, our written price covers the full diagnostic package described - no surprises, no upsells hidden inside the audit.

Frequently Asked Questions - Home Energy Audit in Leander
A home energy audit is a systematic diagnostic evaluation of your building envelope, insulation, and HVAC distribution system using specialized equipment to locate and quantify energy waste. Our Leander audits combine blower-door pressurization testing, thermal imaging, insulation inspection, and duct leakage measurement to produce a prioritized scope with documented numbers, similar to what you’d find with a Cedar Park Home Energy Audit. You receive a written report with photos, readings, and flat pricing for any recommended work.
Most full audits in Leander take 2-4 hours depending on home size, accessibility, and whether duct testing is included. A compact single-story in Old Town Leander might run 2 hours; a 3,500-square-foot home in Crystal Falls with multiple attic accesses and a crawl space could take 4. We schedule ample time and don’t rush the diagnostic work.
Expect $350-$650 for a complete diagnostic package in the Leander market, with smaller homes at the lower end and larger or more complex properties toward the top, comparable to a Home Energy Audit in Georgetown.
