Trusted Home Energy Audit for Cedar Park Homeowners
A Cedar Park Home Energy Audit typically costs $350-$750 for a full assessment and takes 2-4 hours from arrival to written report. Most homeowners who’ve had us out since 2016 see their utility bills drop 15-30% after acting on the findings. Call (737) 245-6428 - we answer live, 24/7, and can usually schedule within 48 hours.
We’ve sealed and insulated over 9,000 homes since 2016, and every one started with either a full energy audit or a targeted blower-door test. In Cedar Park, we regularly see the same pattern: homes built during the 2005-2015 boom were insulated to code minimum, but the top plates were never sealed, can lights were left unbaffled, and ductwork in vented attics leaks 20-40% of conditioned air into the Texas heat. The result is rooms that won’t cool below 78 in August, dust that returns within days of cleaning, and electricity bills that climb every summer regardless of thermostat discipline. Our audit documents exactly where your conditioned air is escaping and what it’ll cost to fix it, with a written price before any work starts and before-and-after blower-door numbers on every air-sealing job so you can verify the result yourself.
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 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 standard pressure. In Cedar Park, we typically see pre-audit readings between 3,500 and 6,000 CFM50 on homes built 2000-2015; after proper air sealing, that same home often tests below 2,500 CFM50. We publish both numbers on every job so you can see the performance change you paid for, not just take our word for it.
Thermal Imaging Inspection
Thermal imaging uses an infrared camera to visualize surface temperature differences, revealing insulation gaps, air leaks, and moisture intrusion that are invisible to the eye. During a Cedar Park summer, missing insulation in a vaulted ceiling shows up as a 15-20°F hot spot; in winter, the same gap reads cold. We scan every accessible wall, ceiling, and floor, then flag the images that matter - not every thermal anomaly needs fixing, and we’ll tell you which ones do. The photos go into your Documented Photo Record, included on every visit, so you have evidence of what we found and where.
Insulation Inspection
We measure existing insulation depth, check for proper placement (baffles at eaves, no contact with can lights), and identify compression, moisture damage, or rodent activity that has degraded R-value. In Cedar Park’s climate zone, attic insulation should be R-38 to R-60; we find homes with R-19 batts that have compressed to R-13, or blown-in fiberglass that has settled below the joists. We note the material type - whether it’s Owens Corning, Johns Manville, Knauf, or another manufacturer - and its condition, then specify exactly what needs removal, addition, or replacement in your written scope.
Duct Leakage Test
A duct leakage test pressurizes your HVAC duct system and measures how much air escapes into unconditioned spaces. In Texas, where ducts often run through 140°F attics, even 15% leakage is a significant efficiency loss; we regularly find 25-40% in homes where ducts were never sealed at the plenum or register boots. We use a duct blaster fan and calibrated manometer to get a precise CFM25 reading, then map the leakage locations with smoke pencil and thermal imaging. The test takes about 45 minutes and tells you whether duct sealing, replacement, or relocation is the right investment.

Brands We Service for Home Energy Audit
We’ve audited homes with Owens Corning insulation systems across Cedar Park’s Ranch at Brushy Creek, Cypress Canyon, and Buttercup Creek neighborhoods, and we’re familiar with their complete residential product line from AttiCat blown-in to Foamular rigid board. When we find Owens Corning products in your attic, we know how they age in Central Texas heat and what failure modes to check for.
We’ve also worked extensively with Johns Manville and Knauf materials in the Leander and Brushy Creek markets, including formaldehyde-free batts and high-density blown-in products that perform well in our humid subtropical climate - whether you need a Home Energy Audit in Leander or nearby. Whether your home was originally insulated with GreenFiber cellulose, a spray-foam application from another contractor, or any other make, we can assess its current condition and recommend next steps based on what we find - not on what we prefer to sell.
Signs You Need Home Energy Audit Right Now
- Your upstairs bedrooms run 8-12°F warmer than the thermostat setting. In Cedar Park’s two-story homes built 2005-2015, this usually points to duct leakage in the attic, inadequate insulation over the top plates, or both. The audit will measure which factor dominates and whether sealing alone solves it or insulation needs to follow.
- Your electricity bill exceeds $0.14/kWh in summer despite reasonable thermostat settings. At current Austin Energy and Pedernales Electric rates, a home over 2,000 square feet with a healthy envelope shouldn’t need more than 2,500 kWh in July. If you’re consistently above that, conditioned air is escaping somewhere the utility company can’t see.
- You feel drafts near outlets, baseboards, or can lights even with doors and windows closed. These are telltale signs of top-plate leakage and unsealed penetrations - common in Cedar Park production homes where speed of construction took priority over envelope tightness. The blower-door test will quantify exactly how much air is moving through these paths.
- Dust reappears on surfaces within 24-48 hours of cleaning. In our climate, excessive dust often means your return ducts are pulling attic air through leaks, or your building envelope is so loose that outdoor particulates are cycling through the house continuously. The duct leakage test and blower-door test together isolate the source.
- You’re considering solar panels or a new HVAC system. Installing either on a leaky envelope is like putting a high-efficiency engine in a car with flat tires. We regularly audit homes in Cedar Park where a $2,500 air-sealing job would deliver more comfort improvement than a $15,000 equipment upgrade. The audit gives you the data to sequence your investments correctly.
Our Home Energy Audit Process - Step by Step
- 1
Schedule and confirm. Call (737) 245-6428 - a live person answers, 24/7. We’ll ask about your home’s square footage, age, and specific concerns, then 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
Written price before any work starts. When our technician arrives, they’ll review the scope with you and provide a flat price for the audit itself. No work begins until you’ve approved it in writing. This is Haven Standard Clause 1, and we don’t waive it.
- 3
Comprehensive diagnostic testing. We run the blower-door test, thermal imaging scan, insulation inspection, and duct leakage test in sequence, typically over 90 minutes to 2 hours. You’re welcome to follow along; we explain what we’re seeing as we work.
- 4
Same-day findings review. Before we pack up, we sit down with you and walk through the photos, readings, and priority recommendations. You’ll see your blower-door number, your duct leakage CFM25, and the thermal images that matter. No waiting for a report that may or may not arrive.
- 5
Written scope and documented record. Within 24 hours, you receive your full report: findings, prioritized recommendations with individual pricing, and a Documented Photo Record of everything we found. If you proceed with work, the 365-Day Done Right Promise applies, and we publish before-and-after blower-door numbers on every applicable job.
How Much Does Home Energy Audit Cost in Cedar Park?
A full home energy audit in Cedar Park typically runs $350-$750 depending on home size and test complexity. A 1,500-square-foot single-story with accessible attic and no duct testing needed usually falls at the lower end; a 3,500-square-foot two-story with zoned HVAC, duct leakage testing, and crawl space access runs toward the higher end. Here’s how the pricing breaks down for common scenarios:
- Basic blower-door test with thermal imaging: $350-$450
- Full audit with duct leakage testing: $550-$750
- Follow-up blower-door verification after air sealing: $150-$250 (often included if we did the original audit)
What moves the price: home square footage, number of HVAC systems, accessibility of attic and crawl space, and whether duct testing is included. What doesn’t move it: the brand of your insulation, the age of your home, or which neighborhood you’re in - we don’t price-discriminate between Buttercup Creek and Ranch at Brushy Creek.
How to avoid overpaying: some utilities and municipalities offer subsidized audits, but these often skip the duct leakage test or use a less sensitive blower door. Ask whether the auditor is using a Minneapolis Blower Door or equivalent calibrated equipment, whether duct testing is included, and whether you’ll receive actual CFM50 and CFM25 numbers or just a pass/fail grade. A real audit gives you data you can act on and verify later.
Our estimate is free, and we offer a Free Second Opinion on any written estimate from another contractor. Bring us their scope; we’ll read it with you and tell you what’s thorough, what’s missing, and what questions to ask before you sign.

Frequently Asked Questions - Home Energy Audit in Cedar Park
A home energy audit is a systematic diagnostic assessment of how your building envelope and mechanical systems use and lose energy. We test air leakage with a blower door, scan for thermal defects with infrared cameras, inspect insulation condition and depth, and measure duct leakage - then give you a prioritized list of fixes with individual pricing. In Cedar Park, most audits we perform reveal that air sealing delivers more comfort per dollar than insulation replacement alone.
A typical audit takes 2-4 hours from arrival to findings review, depending on home size and which tests are included. The blower-door test itself runs 20-30 minutes; thermal imaging adds another 30-45 minutes; duct leakage testing takes 45-60 minutes. We don’t rush the diagnostics, and we don’t leave until you’ve seen the key findings and had your questions answered. Call (737) 245-6428 to check availability - we can usually schedule within 48 hours.
Most full audits in Cedar Park run $350-$750, with basic blower-door and thermal imaging packages starting around $350. We also serve nearby areas with a Round Rock Home Energy Audit.
