Call (213) 306-2607 to book or to get a written price before anyone arrives.
West Hollywood’s mix of 1920s Spanish Revival duplexes, 1960s courtyard apartments, and newer condo towers each present different envelope failures. We’ve audited over 9,000 homes since 2016, and the pattern in WeHo is consistent: original lath-and-plaster walls with no air barrier, recessed can lights cutting through attic insulation, and ductwork in vented crawlspaces leaking 25-40% of conditioned air into the soil. Our home energy audit starts with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - so we measure the problem before proposing a solution. Under Haven Standard Clause 1, you get a written price before any work starts and a documented photo record when we leave. Wes Okafor has built this practice on the principle that you cannot fix what you haven’t measured, and you shouldn’t pay for insulation until the air leaks are sealed.
What Our Home Energy Audit Service Includes
Blower Door Test
The blower door is a calibrated fan mounted in an exterior door frame that depressurizes the house to -50 Pascals, a standard pressure differential that allows us to quantify total envelope leakage in CFM50 - cubic feet per minute at that pressure. In West Hollywood, we regularly see pre-audit readings of 3,500-5,500 CFM50 in 1,200-square-foot bungalows built before 1940, which explains why heating and cooling bills run high despite mild coastal temperatures. Our crew runs the test twice: once before any exploratory work to establish baseline, and again after air-sealing is complete if you proceed with remediation, so you have documented proof of improvement.
Thermal Imaging Inspection
We use FLIR infrared cameras to visualize surface temperature differences that indicate missing insulation, air leakage pathways, or moisture intrusion - the camera doesn’t see through walls, but it maps the thermal boundary with enough resolution to pinpoint gaps. West Hollywood’s marine layer mornings create ideal conditions for thermal imaging from May through October, when the 10-15 degree delta between indoor and outdoor temperatures produces crisp, actionable images. You’ll receive annotated photos in your report showing exactly where attic hatches, chimney chases, and top plates are bleeding conditioned air into unconditioned spaces.
Insulation Inspection
Our technicians access attics, crawlspaces, and wall cavities to measure existing insulation depth, identify compression or displacement, and check for pest damage, water staining, or mold growth that compromises R-value. In WeHo’s flat-roofed mid-century apartments, we often find original rock wool or early fiberglass batts compressed to half their labeled thickness, performing at R-7 or R-9 when the space should hold R-38 or R-49. We document everything with photos and depth measurements, then specify exactly what material - Owens Corning blown fiberglass, Johns Manville mineral wool, or another product matched to your assembly - would restore performance without creating moisture traps.
Duct Leakage Test
A duct blaster pressurizes the HVAC duct system to 25 Pascals while registers are sealed, measuring leakage to outside in CFM25 - the air escaping into attics, crawlspaces, or wall cavities rather than reaching your rooms. West Hollywood’s prevalence of central furnaces in closet installations with flex duct running through hot attics creates predictable failure points: disconnected boots at ceiling penetrations, crushed flex behind insulation, and panned joist bays that were never properly sealed. We map leakage by zone so you know whether the problem is a single disconnected return or systemic deterioration requiring full duct replacement.

Brands We Service for Home Energy Audit
Our audit findings directly inform material specifications, and we maintain working knowledge of the full performance characteristics for Owens Corning’s complete insulation line - from AttiCat blown-in fiberglass to Foamular rigid board - because we’ve specified their products on hundreds of envelope retrofits and understand how each performs in West Hollywood’s specific climate zone. We also regularly evaluate Johns Manville mineral wool for fire-blocking and acoustic applications in multi-family buildings throughout the WeHo area, where Title 24 fire-resistance assemblies and STC ratings matter as much as thermal performance. Whether your existing insulation is Owens Corning, Johns Manville, or any other make, we can assess its condition and specify the right replacement or supplement.
We’ve audited homes with Demilec open-cell spray foam in recent additions and GreenFiber cellulose in older retrofits, and we know the failure modes of each: Demilec’s hydrophilic open-cell can retain moisture if the vapor profile isn’t calculated correctly, while GreenFiber’s boric-acid fire treatment degrades with repeated wetting. Our reports name the specific product already in your walls and specify whether it can stay, needs supplementation, or requires full removal. No proprietary lock-in means we recommend what performs, not what we stock.
Before
AfterSigns You Need Home Energy Audit Right Now
- Your PG&E bill spikes 30% or more in summer despite mild West Hollywood weather. A properly sealed and insulated 1,200-square-foot home in WeHo should cool for under $120/month in August. If you’re paying $180 or more, the building envelope is leaking conditioned air faster than the HVAC can replace it, and the equipment is cycling excessively to compensate.
- You feel drafts from outlets, baseboards, or recessed light fixtures on windy days. These are telltale signs of top plate and bottom plate air leakage, where the wall cavity connects to attic or crawlspace pressure zones. In West Hollywood’s older buildings with balloon framing or unsealed platform framing, this pathway can account for 15-20% of total envelope leakage.
- One room stays 8-10 degrees hotter or colder than the rest of the house. Duct leakage, missing insulation over that room’s ceiling, or a disconnected supply boot are the usual culprits. We use the blower door and thermal camera together to isolate whether the problem is distribution or envelope, so you don’t pay for the wrong fix.
- Your attic insulation looks flat, discolored, or has visible pest trails. Compression reduces R-value proportionally - insulation at half its original thickness performs at roughly half its rated thermal resistance. Discoloration indicates air filtration (dirt carried by leaking air), and rodent activity compromises both insulation and air quality. Our inspection documents the extent so you know whether spot repair or full replacement is warranted.
- Your HVAC contractor has recommended a larger system. Oversizing is the most expensive mistake in residential HVAC, and it’s almost always prescribed because the envelope hasn’t been tested. A home energy audit in West Hollywood often reveals that proper air sealing and insulation would allow a smaller, more efficient system - or make the existing one adequate - saving $3,000-$8,000 in equipment costs alone.
Our Home Energy Audit Process - Step by Step
- 1
Schedule and written price confirmation. When you call (213) 306-2607, a live person answers - no voicemail, no callback queue. We ask about home size, year built, and specific concerns, then provide a written price range before confirming the appointment. Under Haven Standard: Have it in writing. No work starts without it.
- 2
Arrival and walkthrough with named technician. You get a text when your technician is en route, and they arrive in a marked vehicle with photo ID. We walk the property together to identify access points, note any safety concerns like active roof leaks or exposed wiring, and confirm the testing scope before setting up equipment.
- 3
Blower door test and thermal imaging. The crew seals the house, installs the blower door, and runs the depressurization test to establish CFM50 baseline. Thermal imaging follows immediately while the pressure differential is active, making air leakage pathways visible in real time. We show you the thermal images on-site and explain what we’re seeing.
- 4
Attic, crawlspace, and duct inspection. Technicians enter accessible building cavities with headlamps and cameras, measuring insulation depth, photographing conditions, and mapping duct routing. In West Hollywood’s tight crawlspaces - common in the Norma Triangle and Spaulding Square areas - we use articulating borescopes to inspect areas too confined for full entry.
- 5
Written report delivery with prioritized recommendations. Within 48 hours, you receive a PDF report with blower-door results, thermal images with annotations, insulation depth measurements, duct leakage CFM25 by zone, and a prioritized scope of work with flat pricing for each phase. The report includes before-and-after blower-door projections if air sealing is performed, so you know the expected performance improvement before committing.
How Much Does Home Energy Audit Cost in West Hollywood?
A home energy audit in West Hollywood runs $350-$550 for most single-family homes under 2,500 square feet, and $550-$850 for larger homes, multi-family buildings, or audits requiring additional testing like zonal pressure diagnostics or combustion safety analysis. Condos and apartments typically fall at the lower end of the range because the testing scope is limited to the unit envelope rather than the full building.
Several factors move the price within these ranges. Homes built before 1940 with complex rooflines and multiple additions take longer to test thoroughly and may require additional thermal imaging passes. Duct leakage testing adds $150-$250 if the HVAC system is inaccessible or uses non-standard register sizes that require custom sealing. Multi-zone systems with more than two thermostats need extended diagnostic time to isolate leakage by zone.
What affects the price most is scope clarity. An audit scoped as “check the attic” costs less than a full building-envelope assessment with combustion appliance zone testing and infrared documentation of every exterior wall. We specify exactly what’s included in your written price before confirming the appointment, so there’s no scope creep or surprise charges on arrival.
To avoid overpaying, be wary of “free” audits offered by insulation companies that use the visit primarily to sell their product. A diagnostic audit should be performed by a technician who gains nothing from the remediation scope they recommend. Our pricing is flat for the audit itself; we have no incentive to recommend more insulation than you need, and our before-and-after blower-door documentation holds us accountable to measurable results.
Every audit includes the full diagnostic visit, written report with photos and thermal images, and a free second opinion on any competing estimate you bring us. If you proceed with remediation work, the audit fee is credited toward the project total.

Frequently Asked Questions - Home Energy Audit in West Hollywood
A Beverly Hills Home Energy Audit is a systematic diagnostic evaluation of your building envelope, insulation, and HVAC distribution system using specialized equipment to measure air leakage, thermal performance, and duct integrity. In West Hollywood, our standard audit includes a blower-door test, thermal imaging, insulation inspection, and optional duct leakage testing, all documented in a written report with prioritized repair recommendations. The goal is to identify the specific defects causing high energy bills and comfort problems before you spend money on fixes that may not address the root cause.
Most home energy audits in West Hollywood take 2-4 hours for single-family homes and 1.5-2.5 hours for condos and apartments. Older homes with complex additions, limited attic access, or crawlspaces requiring borescope inspection take longer, while newer condos with straightforward envelope assemblies often finish at the shorter end. You’ll receive the written report within 48 hours of the visit, and we schedule a phone walkthrough to answer questions about the findings and recommended scope.
A Home Energy Audit in Culver City typically costs $350-$550 for homes under 2,500 square feet and $550-$850 for larger properties or multi-family buildings. Condos and apartments usually fall at the lower end. The price includes all diagnostic testing, thermal imaging, written report with photos, and a free second opinion on any competing estimate. Call (213) 306-2607 for a written price specific to your home - estimates are free, and the audit fee is credited toward any remediation work you proceed with.
Yes, we regularly audit homes with existing Owens Corning fiberglass, Johns Manville mineral wool, and all other major insulation brands. Our inspection assesses whether the installed product is performing to specification regardless of manufacturer, and our recommendations are brand-neutral based on your specific assembly and climate zone. If replacement or supplementation is needed, we specify the right product for the application - whether that’s Owens Corning, Johns Manville, or another manufacturer - with no proprietary lock-in.
Same-day scheduling is available for most West Hollywood addresses when you call before noon, and next-day scheduling is standard for calls received later in the day. We don’t treat energy audits as emergency services - there’s no burst pipe or electrical hazard - but we understand that timing matters when you’re evaluating a major insulation investment or responding to a failed home inspection contingency. A live person answers calls 24/7 to schedule and confirm appointments.
The audit itself is covered by our 365-Day Done Right Promise - if any finding in your report is later determined to be inaccurate due to our error, we re-audit at no charge. If you proceed with remediation work recommended in the audit, that work carries the full Haven Standard warranty: written scope, written warranty, and before-and-after blower-door documentation so you can verify the result. Under Haven Standard Clause 1, you receive all documentation before anyone lifts a tool.
Close all windows and exterior doors at least 12 hours before the audit so we can test under normal operating conditions, and avoid using fireplaces or wood stoves for 24 hours prior. Make attic and crawlspace access points clear of storage, and have your last 12 months of utility bills available if possible - they help us correlate consumption patterns with envelope performance. You don’t need to be present for the full audit, but we prefer a 15-minute walkthrough at the start to identify specific comfort complaints and a 15-minute review at the end to show preliminary thermal images.
