Trusted Home Energy Audit for Santa Clarita Homeowners
A Santa Clarita Home Energy Audit tells you exactly where your house is leaking conditioned air and why your PG&E or SCE bill keeps climbing every summer. Most homes we test in Valencia, Saugus, Canyon Country, and Newhall are losing 20 to 30 percent of the air they pay to heat or cool through attic bypasses, leaky ductwork, and under-insulated exterior walls. Rob Callahan, owner and lead installer at Evergreen Insulation, performs the audit himself using calibrated diagnostic equipment, so what you get is data from the person who would also do any recommended work. If you’re tired of guessing why the upstairs is ten degrees hotter than the downstairs, call (661) 669-8515 and we’ll schedule your audit, often the same week.
What Our Home Energy Audit Service Includes
Our audits in Santa Clarita are diagnostic first and sales conversation second. We measure, we test, we show you the numbers, and then we talk about what’s worth fixing. Here’s what’s included in every audit we perform.
Blower Door Test
A blower door test depressurizes your home with a calibrated fan mounted in an exterior door frame, then measures exactly how much air is leaking through the building envelope. This is the single most important number for understanding Santa Clarita energy performance, because our summer temperature swings between 100-degree days and 50-degree nights force your HVAC system to work against every leak you have. Evergreen Insulation runs this test on every audit and gives you a CFM50 reading, which tells us how leaky your house is compared to building standards. Without this number, any insulation recommendation is just a guess.
Thermal Imaging Inspection
We use an infrared camera to see where heat is entering or escaping through your walls, ceilings, and around windows and doors. In Santa Clarita, where afternoon sun pounds west-facing walls in Stevenson Ranch and Castaic, thermal imaging often reveals missing insulation batts and voids that would otherwise stay hidden behind drywall. Rob walks the entire house with the camera while the blower door is running, so temperature signatures show up clearly. The images become part of your audit report, so you see the problems yourself instead of taking our word for it.
Insulation Inspection
We access your attic, crawl space, and accessible wall cavities to document what insulation exists, how deep it is, and whether it’s still doing its job. In homes throughout the Santa Clarita Valley, we regularly find original 1980s and 1990s fiberglass that’s compressed, rodent-soiled, or missing entirely around top plates and eaves. Our inspection includes checking for moisture damage, pest intrusion, and air gaps where insulation should sit tight against the framing. Evergreen Insulation documents all of this with photos and measurements before recommending anything.
Duct Leakage Test
The average duct system in Santa Clarita leaks 20 to 30 percent of the air moving through it, which means you’re paying to heat or cool your attic and crawl space. We pressure-test your ductwork to measure how much conditioned air escapes before it reaches your registers. This matters in Santa Clarita specifically because so many homes here have ducts running through unconditioned attics that hit 130 degrees or more on summer afternoons. If your ducts are leaking, even the best insulation in the world won’t fix your comfort problem, and our test shows you exactly how big that problem is.

Brands We Service for Home Energy Audit
Because Evergreen Insulation stocks and specifies eight major material brands, our audits are never skewed toward one product line. When we inspect insulation, we know what good Owens Corning fiberglass or Rockwool mineral wool should look like, how it should be installed, and when it’s failing. That product-level familiarity means our audit reports include practical recommendations like “this CertainTeed batt is R-19 but compressed to R-11 value because it’s wedged under a catwalk” rather than generic advice.
We also work routinely with Johns Manville and Knauf products in both inspections and remediation projects, so when we find installation defects or age-related degradation, we can tell you honestly whether patching or full replacement makes sense. Whether your home has Rockwool, fiberglass, spray foam, or a mix of everything, our audit identifies what’s there now and what needs to change. The brand never drives our recommendation; the performance data does.
Signs You Need a Home Energy Audit Right Now
- Your summer electric bill keeps setting records. Santa Clarita’s July and August highs regularly exceed 100 degrees, and if your bill climbs every year while your usage stays the same, your home’s thermal envelope is degrading. An audit finds where the cool air is going before you spend another season overpaying.
- Some rooms are always too hot or cold. When your hallway is comfortable but the bedrooms in Canyon Country or Saugus never cool down, you’re looking at duct leakage, insulation voids, or both. An audit pinpoints the cause instead of leaving you to run the AC harder and hope for the best.
- You smell attic or crawl space air inside the house. Musty or dusty air drifting down from the attic is a sign your home’s air barrier has holes. That’s conditioned air escaping and unfiltered air coming in, and it affects both comfort and indoor air quality.
- Your home was built before 2000 and hasn’t had an energy retrofit. Building codes for insulation and air sealing were far looser before the early 2000s, and most original installations have settled, compressed, or been disturbed by contractors over the years. An audit gives you a before-and-after baseline so you know what’s actually deteriorated.
- You’ve found rodent droppings or nesting material in the attic. Rodents shred insulation and leave urine and droppings that degrade its R-value and create health concerns. Our attic inspection during the audit documents pest damage, and our attic cleaning and rodent proofing service handles the fix.
Our Home Energy Audit Process — Step by Step
- 1
Walk-through and interview. Rob starts by asking where you feel uncomfortable, which rooms you avoid, and what your utility bills have looked like over the last year. He walks the entire house with you, inside and outside, looking at attic access, crawl space access, window conditions, and the age and condition of your HVAC equipment. This step takes about 30 minutes and gives us a working map of your home’s likely problem areas.
- 2
Blower door and pressure setup. We install the blower door in an exterior door frame and seal off your fireplace damper, dryer vents, and any intentional openings so the test reads your actual envelope leakage. The fan depressurizes the house to a standard 50 pascals of pressure, and we record the CFM50 number on the spot.
- 3
Thermal imaging sweep. With the house depressurized, outside air rushes in through every leak, making temperature differences visible to the infrared camera. Rob scans every wall, ceiling, floor, window, and door, capturing images that document where insulation is missing or air is bypassing it.
- 4
Duct leakage and insulation measurement. We pressure-test your ducts using a duct blaster to quantify leakage, then access the attic and crawl space to measure insulation depth, check for moisture, and photograph everything we find. We look for anything a basic visual inspection would miss, like disconnected ducts, unsealed top plates, and baffle failures at soffit vents.
- 5
Report and recommendations. You get a written summary of everything we measured and saw, with photos, numbers, and a prioritized list of fixes. We tell you which improvements will pay for themselves fastest and which can wait. The report is yours to keep whether or not you hire Evergreen Insulation to do any remediation work.
How Much Does a Home Energy Audit Cost in Santa Clarita?
A home energy audit in Santa Clarita typically runs $300 to $600—see how much Home Energy Audit costs—for a full diagnostic visit that includes a blower door test, thermal imaging, insulation inspection, and duct leakage testing. Homes under 2,000 square feet with accessible attics and crawl spaces usually land on the lower end, while larger homes, multi-zone HVAC systems, or complicated access points push toward the upper end. When you compare that audit cost to the $800 to $1,500 a year a leaky home can waste in heating and cooling, the diagnostic pays for itself quickly.
What affects the price most is home size, accessibility, and how many systems we’re testing. A single-story ranch in Valencia with a clean attic is faster to audit than a two-story in Stevenson Ranch with multiple attic accesses and a finished garage. We don’t charge hourly surprise rates; your quote is flat and agreed on before we start. A free estimate includes a walk-through and a clear scope of what the audit covers, so you know the number before any equipment comes off the truck. Call (661) 669-8515 and we’ll give you an exact audit price for your home.

Because Rob works with eight major brands, he can tell you honestly whether your existing insulation can be supplemented or should be replaced. Call (661) 669-8515 to find out what’s happening in your attic.
We offer same-week scheduling for most Santa Clarita home energy audits, and we can often accommodate next-day or emergency calls when there’s an urgent moisture or rodent issue involved. If you’re seeing active water intrusion, mold growth, or pest damage in your attic or crawl space, that takes priority in our schedule. Call (661) 669-8515 and we’ll let you know our earliest available appointment, often within 48 hours.
Our audit findings are documented with instrument readings and thermal images, so you have verifiable data showing exactly what we measured. If we perform remediation work based on the audit, that work carries our workmanship guarantee, and the materials carry their manufacturer warranties. Rob Callahan stands behind every audit and every repair he performs, because he’s the one doing both. Call (661) 669-8515 to discuss what your audit will cover.
Before we arrive, clear attic and crawl space access points of stored items, note down any rooms that feel consistently uncomfortable, and gather a year’s worth of utility bills if you have them. Close all windows and doors at least an hour before the audit, and let us know about any known issues like pest activity or previous insulation work. During the blower door test you’ll need to stay inside or leave pets in a closed room, since the fan creates a noticeable airflow.
