Trusted Home Energy Audit for Torrance Homeowners
A professional Torrance Home Energy Audit typically costs $350-$850 depending on home size and test scope, and most audits are scheduled within 48 hours with same-day reporting on findings. Our crew has performed envelope diagnostics on over 9,000 homes since 2016, and we publish before-and-after blower-door numbers on every job so you can verify the result in a single figure. Call (424) 704-9866 to book your audit - a live person answers 24/7, and you’ll get a written price before any work starts.
Torrance sits in a unique spot. We’re close enough to the coast for marine layer moisture to complicate attic conditions, but far enough inland to see real summer heat that pushes air conditioning systems hard. That combination - salt air, humidity swings, and thermal load - shows up in our blower-door readings differently than it does in Gardena or Compton. We’ve seen 1950s ranch homes in Southwood with original knob-and-tube penetrations bleeding conditioned air into vented attics, and we’ve seen newer construction in West Torrance where the insulation was installed before the top plates were sealed, trapping moisture against drywall. The audit finds what you can’t see from the hallway. Wes Okafor and our team treat air sealing as a hard prerequisite, not an upsell, because blowing insulation over an unsealed attic floor is something we simply won’t do.
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 conditioned air your building envelope is losing. We depressurize your home to 50 Pascals - a standard pressure differential - and measure airflow in CFM50, cubic feet per minute at that pressure. In Torrance, we regularly see pre-audit readings between 3,500 and 6,000 CFM50 in homes built before 1980, which translates to complete air exchange every 20-30 minutes under normal conditions. Our crew seals top plates, can lights, and penetrations, then re-tests so you walk away with documented before-and-after numbers under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool.
Thermal Imaging Inspection
Thermal imaging, or infrared thermography, reveals surface temperature differences that indicate missing insulation, air leaks, or moisture intrusion. We use FLIR cameras during the blower-door test when the pressure differential makes leaks visible as cold streaks on warm surfaces, or vice versa depending on season. In Torrance’s coastal climate, we frequently find thermal bridging at knee walls in second-story additions - common in neighborhoods like North Torrance where 1960s-70s split-levels were expanded upward without proper envelope continuity. The images become part of your Documented Photo Record, included on every visit, not available on request.
Insulation Inspection
We measure existing insulation depth, check for compression or settlement, identify gaps at eaves and around chases, and note whether vapor barriers are present and correctly positioned. Torrance homes built during the 1950s-70s often have original rock wool or early fiberglass batts that have settled below current Title 24 standards; homes from the 1980s-2000s may have blown-in fiberglass that was installed before air sealing was understood as prerequisite. We specify exactly what we found - “R-11 compressed to R-8 in the northeast corner, with a 4-foot gap at the plumbing chase” - rather than generic ratings. If removal and replacement is needed, we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, and other manufacturers with no proprietary lock-in.
Duct Leakage Test
A duct leakage test pressurizes your HVAC duct system to measure how much conditioned air escapes before reaching your rooms. We seal registers, connect a calibrated fan to the return, and measure leakage to outside the thermal envelope - the air you’re paying to heat or cool that ends up in your attic or crawl space. In Carson and Torrance, where many homes have original galvanized ductwork or 1990s flex duct that’s degraded in attics that hit 140°F in August, we commonly find 25-40% leakage to outside. That’s not an efficiency problem; it’s a comfort and air quality problem, because leaky return ducts pull attic air into your living space. We document the leakage percentage and show you exactly which runs need sealing or replacement.

Brands We Service for Home Energy Audit
We’ve worked extensively with Owens Corning systems, particularly their AttiCat blown-in fiberglass and ProPink Loosefill products that we encounter in Torrance homes upgraded during the 2010s energy rebate programs. Their L77 loose-fill requires specific density to achieve labeled R-value, and we’ve found instances where previous contractors installed it at insufficient depth over unsealed top plates - the thermal image shows the pattern clearly, and the blower-door test confirms the air movement. We know how to read their product labels and verify that what was specified is what exists in your attic.
Johns Manville and Knauf materials are also common in our market. JM’s Spider custom-fit fiberglass and Knauf’s Jet Stream ULTRA blown-in wool both perform well when installed to manufacturer spec with proper air sealing beforehand. We’ve audited homes in Rancho Palos Verdes and Manhattan Beach where high-end Knauf EcoSeal was specified but not paired with adequate air sealing of electrical penetrations - the product did its job, but the assembly failed because the envelope wasn’t addressed first. Rockwool’s stone wool batts, increasingly specified for fire resistance in hillside construction near Palos Verdes, require different cutting and fitting techniques than fiberglass; we inspect for gaps at framing and compression at wiring that compromise performance. Whether you have Owens Corning, Johns Manville, Knauf, Rockwool, or any other make, we can read what was installed, assess whether it was installed correctly, and tell you exactly what needs to change.
Signs You Need Home Energy Audit Right Now
- Your upstairs rooms stay hot while the downstairs over-cools. This temperature stratification usually indicates duct leakage, inadequate attic insulation, or both. In Torrance’s two-story homes, particularly the 1970s-90s construction in South Torrance and Walteria, we find that the upstairs thermostat location masks the real problem: conditioned air is escaping before it reaches the second floor, while the first floor sensor tells the system to shut off.
- Your energy bills spike in August and January despite moderate thermostat settings. Coastal Southern California doesn’t have extreme seasons; if your usage curve looks like Phoenix or Chicago, your envelope is leaking. We compare your usage against degree-day data and square footage to flag anomalies that warrant blower-door testing.
- You feel drafts near outlets, baseboards, or can lights even when windows are closed. These are telltale signs of top plate and penetration leaks that bypass insulation entirely. In older Torrance neighborhoods like Old Torrance and the area near Torrance Boulevard, we’ve traced drafts to unsealed balloon framing cavities that connect basement to attic.
- Your attic insulation looks uneven, discolored, or has visible gaps. Dark streaks on fiberglass indicate air filtration - the insulation is acting as a filter as conditioned air leaks through. Gaps at eaves or around chimneys are installation defects that render even high-R-value materials ineffective. We photograph everything and show you what we found.
- You’re considering solar panels, a heat pump, or an EV charger. Adding load to a leaky envelope is expensive engineering. We’ve audited homes in Hawthorne and Lawndale where homeowners installed 8kW solar arrays only to discover that 35% of their conditioned air was escaping to the attic. Seal first, then right-size your mechanical systems.
Our Home Energy Audit Process - Step by Step
- 1
Schedule and confirm. Call (424) 704-9866 or text us - a live person answers 24/7, no voicemail loops. We confirm your address, home size and age, and any specific concerns. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
- 2
Exterior and interior walkthrough. Our technician examines wall construction, window age and condition, visible penetrations, and attic and crawl space access. We note the HVAC system location, duct routing, and any prior insulation or energy work. This takes 20-30 minutes and informs which tests we’ll prioritize.
- 3
Blower-door test and thermal imaging. We set up the blower door, establish the 50 Pascal pressure differential, and capture thermal images while the house is depressurized. The combination reveals leaks that neither test would find alone. We measure and record the CFM50 baseline.
- 4
Attic, crawl space, and duct inspection. With diagnostic data in hand, we enter the attic and crawl space to identify specific defects: unsealed top plates, disconnected duct boots, missing insulation at eaves, moisture staining, rodent damage. We photograph everything for your Documented Photo Record.
- 5
Written report and price. You receive a written scope with findings, prioritized recommendations, and a flat price for any work - before anyone lifts a tool. If you have a competing quote, we offer a Free Second Opinion; we’ll read it with you line by line. The report includes your blower-door number, thermal images, and photos. On applicable jobs, we provide before-and-after blower-door readings so you can verify the air-sealing result.
How Much Does Home Energy Audit Cost in Torrance?
A standard home energy audit for a single-family home in Torrance runs $350-$550 for homes under 2,500 square feet, and $550-$850 for larger homes or those requiring duct leakage testing in addition to the standard envelope assessment. A standalone blower-door test with thermal imaging starts around $350; adding comprehensive insulation inspection and duct leakage testing moves the price toward the upper end of that range. Multi-family properties, historic homes with complex envelope conditions, or audits requiring access to multiple attic zones - common in the hillside areas of Rancho Palos Verdes and Palos Verdes Estates - may run higher based on time and equipment needed.
Several factors affect what you’ll pay. Home size and complexity are the primary drivers: a 1,200-square-foot ranch in North Torrance with a single attic zone takes less time than a 3,500-square-foot two-story in West Torrance with conditioned and unconditioned attic spaces, a crawl space, and a basement mechanical room. The scope of testing matters too - a blower-door test alone is faster and less expensive than a full diagnostic that includes duct pressurization, combustion safety testing for gas appliances, and multiple thermal imaging passes. Seasonal demand can affect scheduling but not our pricing; we don’t surge prices in August when air conditioning complaints peak.
To avoid overpaying, get the scope in writing before anyone starts. Some competitors advertise low audit fees but charge separately for the “detailed report” or upsell unnecessary services during the visit. Our written price under Haven Standard includes the full diagnostic, the written report, the Documented Photo Record, and the blower-door numbers - no add-ons, no surprises. If you’re comparing quotes, bring us a competing estimate; our Free Second Opinion means we’ll read it with you and flag what’s specified, what’s omitted, and what assumptions don’t match your home’s actual condition.
Every audit includes the blower-door test, thermal imaging, insulation inspection, and written findings. Duct leakage testing is added when HVAC performance is a concern or when the homeowner is considering equipment replacement. Call (424) 704-9866 for an exact quote - estimates are free, and you’ll get the written price before any work starts.
