Trusted Home Energy Audit for Glendale Homeowners
A home energy audit in Glendale typically costs $350-$750 for a full diagnostic package, and most audits are completed in 3-4 hours with same-day scheduling available. You’ll receive a written report with blower-door numbers, thermal images, and prioritized recommendations - not a generic checklist.
We’ve been sealing and insulating homes under The Haven Standard since 2016, and we’ve completed over 9,000 jobs with a written price before any work started and a documented record when the crew left. Glendale’s mix of 1920s Spanish Revival bungalows, mid-century ranch homes, and newer condos near the Americana presents distinct envelope problems: original lath-and-plaster walls with no cavity insulation, attic hatches that leak conditioned air into vented attics, and duct systems routed through hot crawl spaces that lose 20-30% of cooling capacity before the air reaches the register. In the Verdugo Woodlands, we regularly see homes with original knob-and-tube wiring that limits insulation contact; in Rossmoyne, we find beautiful vintage casement windows with failed weatherstripping that blower-door tests flag immediately. Our technicians are background-checked, uniformed, and arrive with a written scope - no surprises, no upsell pressure. Call (213) 474-3828 to schedule; a live person answers 24/7.
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 airflow in CFM50 - cubic feet per minute at that standard pressure. In Glendale, we typically see pre-audit readings of 3,500-5,500 CFM50 in homes built before 1960, and 2,500-4,000 CFM50 in homes from the 1970s-1990s. After our air-sealing work, those same homes usually test at 1,800-2,800 CFM50, and we publish both numbers on every applicable job so you can verify the result. You need this test if your utility bills spike during Glendale’s August heat waves or if rooms farthest from the HVAC unit never reach set temperature. Topside Attic Insulation Glendale uses a Retrotec or Minneapolis Blower Door system calibrated annually, and we perform the test twice - once before any work is proposed, and again after sealing is complete.

Thermal Imaging Inspection
Thermal imaging, or infrared thermography, uses a FLIR camera to visualize surface temperature differences that reveal hidden air leaks, missing insulation, and moisture intrusion. During a Glendale audit, we scan every exterior wall, ceiling, and accessible floor after the blower door has been running for 10 minutes - the pressure difference makes leaks visible as dark streaks on the camera’s display. In the hills above Glenoaks Boulevard, we regularly find thermal bypasses where stucco meets the roofline with no blocking; in condo conversions near Central Avenue, we see party walls that were never air-sealed during renovation. You need thermal imaging if you’ve noticed mysterious hot spots in summer, cold walls in winter, or if a previous contractor “insulated” without documenting what they actually found. Our technicians carry FLIR T540 cameras with 464 × 348 resolution, and every thermal image is saved to your Documented Photo Record with an annotation explaining what it shows.

Insulation Inspection
An insulation inspection measures depth, density, and condition of existing material, identifies gaps and compression, and checks for moisture damage or rodent contamination. In Glendale attics, we commonly find original rock wool or vermiculite in homes built before 1950, fiberglass batts installed upside-down or with facing against the wrong side, and blown-in cellulose that has settled 30-40% below labeled R-value. The inspection includes a density probe test - we push a marked wire through the insulation to the drywall and record depth at 10+ locations - because settled insulation rarely performs at its original rating. You need this inspection if your attic was insulated more than 15 years ago, if you’ve had roof leaks or rodent activity, or if you’re considering adding more material without knowing what’s there. Topside Attic Insulation Glendale will not quote additional insulation until we’ve verified the existing layer is dry, uncontaminated, and properly installed - per Haven Standard, sealed first, then insulated.

Duct Leakage Test
A duct leakage test pressurizes your HVAC duct system and measures how much conditioned air escapes to the attic, crawl space, or outdoors rather than reaching your rooms. We seal all registers and returns, connect a Duct Blaster fan to the air handler, and measure leakage at 25 Pascals - expressed as CFM25 or as a percentage of system airflow. In Glendale’s older homes with original metal ducts wrapped in asbestos-containing material, we regularly find 25-40% total leakage; even in 1990s homes with flex duct, poor connections at the plenum and wye fittings often leak 15-25%. You need this test if some rooms are consistently 5-10 degrees different from the thermostat, if your air filter gets dirty unusually fast, or if you’ve replaced your HVAC unit without addressing the distribution system. Our test includes a visual inspection of every accessible duct run, and we photograph damage, disconnections, and insulation gaps for your written report.

Brands We Service for Home Energy Audit

We’ve worked with Owens Corning insulation systems since 2016, and we know their AttiCat blown-in fiberglass and ProPink Loosefill products well enough to spot installation errors that void the limited warranty - compression in corners, insufficient depth at eaves, and failure to install proper baffles for soffit ventilation. In Glendale’s tighter attic spaces, particularly in the hillside homes above Mountain Street, we often recommend Owens Corning’s higher-density batts when blown-in application would require removing finished storage decking.
Johns Manville’s Spider custom-fit fiberglass and Climate Pro blow-in systems are common in newer Glendale construction, and we’ve audited dozens of homes where the original installer used the wrong blowing machine settings, leaving clumps and voids that our thermal cameras catch immediately. We also encounter GreenFiber cellulose in eco-conscious renovations near Adams Hill, and Demilec spray foam in high-performance retrofits around the Chevy Chase Canyon area. Whether your home has Owens Corning, Johns Manville, GreenFiber, Demilec, or any other material, we can assess its condition and performance. We carry no proprietary product lock-in - our recommendations are based on what your specific envelope needs, not on what we stock.
Before
AfterSigns You Need Home Energy Audit Right Now
- Utility bills that spike 30% or more during Glendale’s summer heat. If your August electric bill hits $400+ while neighbors in similar homes pay $250, your envelope is leaking conditioned air or your ducts are delivering it to the wrong places. The audit pinpoints which problem dominates so you don’t spend money on insulation when sealing would have solved it.
- Rooms that never reach thermostat setpoint, especially west-facing bedrooms. In Glendale’s climate, afternoon solar gain through unshaded windows is real, but if your HVAC runs continuously and the room still lags 5+ degrees behind, the cause is usually duct leakage or missing insulation in the attic above. A blower-door and thermal imaging combination finds it in under an hour.
- Drafty floors over crawl spaces, common in homes near the Verdugo Wash. Older Glendale homes with raised foundations often have unsealed crawl space vents that admit outdoor air year-round, plus subfloor insulation that has fallen or been removed by rodents. The audit measures how much this contributes to your total load and whether encapsulation is warranted.
- Ice damming or moisture stains on ceiling drywall after rare winter rains. Even in Glendale’s mild climate, poorly air-sealed attic floors allow warm, moist interior air to reach cold roof sheathing in January, where it condenses and stains drywall. The audit finds the thermal bypasses - can lights, chimney chases, top plates - that cause this pattern.
- You’re considering solar panels or a heat pump upgrade. California’s heat pump rebates and NEM 3.0 solar rules make both attractive, but neither performs well in a leaky home. We’ve audited Glendale homes where the proposed 5-ton heat pump would have been oversized by a full ton after proper air sealing - saving $3,000+ on equipment and improving comfort. The audit should come first.
Our Home Energy Audit Process - Step by Step

- 1
Schedule and confirm. Call (213) 474-3828 or text us; a live person answers 24/7. We’ll ask about your home’s year built, square footage, and specific concerns, then schedule a 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. Your technician arrives with a flat-rate price for the audit package - no hourly mystery, no “it depends” that balloons later. The price covers blower-door testing, thermal imaging, insulation inspection, duct leakage testing if accessible, and a written report with prioritized recommendations. You approve it in writing before we start.
- 3
Diagnostic testing and documentation. We run the blower-door test first to establish baseline leakage, then use thermal imaging under pressure to find leaks, inspect all accessible insulation with depth probes, and test duct leakage if the system is accessible. Every finding is photographed and annotated for your Documented Photo Record.
- 4
Same-day verbal briefing. Before leaving, your technician walks you through the thermal images and blower-door number, explains what each finding means for your comfort and utility bills, and answers questions. No waiting days for a report while details fade.
- 5
Written report within 48 hours. You receive a PDF with blower-door and duct leakage numbers, thermal images with annotations, insulation depth map, prioritized repair scope with flat prices for each item, and our recommendation of what to do first, second, and third. If you choose to proceed, that scope becomes your written contract - Haven Standard Clause 1, always.
How Much Does Home Energy Audit Cost in Glendale?
A full home energy audit in Glendale runs $350-$750 depending on home size, accessibility, and which diagnostics you need. A 1,200-square-foot bungalow in Adams Hill with a vented attic and accessible crawl space typically falls at $350-$450 - blower door, thermal imaging, insulation inspection, and written report included. A 3,500-square-foot hillside home in Chevy Chase Canyon with multiple HVAC zones, a sealed attic with spray foam, and limited access points usually runs $550-$750 because the duct leakage testing requires additional setup and the thermal survey takes longer.
What moves the price: square footage (larger homes need more thermal imaging time), number of HVAC systems (each adds duct leakage testing), accessibility (steep roofs, tight crawl spaces, finished attics), and whether you need same-day scheduling. What doesn’t move the price: we don’t charge extra for the Documented Photo Record, and we don’t tack on “report fees” - those are included.
To avoid overpaying, get a written scope that specifies exactly which tests are included and what equipment will be used. Some Glendale competitors quote a low “audit” price that covers only a visual walkthrough with no blower door or thermal imaging - essentially a sales call with a clipboard. Ask specifically: will you run a calibrated blower door? Will you use a thermal camera under pressure? Will I receive actual CFM50 and CFM25 numbers, or just a generic “your home leaks” summary? If the answer is vague, keep looking.
Our free estimate for follow-up work is exactly that - free, with a written scope and flat price, no obligation to hire us for the audit or the repairs. Bring us a competing quote; under Haven Standard, we provide a Free Second Opinion on any written estimate. We’ll read it with you and tell you where the scope differs from what we found.
