Trusted Home Energy Audit for Tustin Homeowners
A Home Energy Audit - Tustin typically costs $300-$650 for a full assessment including blower-door test and thermal imaging, and most audits are scheduled within 2-3 business days. The audit identifies where your conditioned air escapes and prioritizes fixes by return on investment, so you’re not guessing where to spend money.
We’ve completed energy audits on over 9,000 homes since 2016, and every one started with a written price and ended with a documented record. In Tustin’s climate, where summer afternoons push attic temperatures past 140°F and winter evenings can dip into the low 40s, the homes that perform best are the ones where someone measured the leaks before recommending insulation. We operate under The Haven Standard, which means flat pricing, written scope, and a 365-Day Done Right Promise on any work that follows the audit. Call (657) 286-7673 to schedule. A live person answers 24/7.
What Our Home Energy Audit Service Includes
Blower Door Test
The 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. In Tustin, we regularly see readings above 3,500 CFM50 in pre-1990 homes, especially in neighborhoods like Tustin Ranch and Old Town where original construction predates modern air-sealing codes. Our crew records the before number, then uses it to locate leaks with smoke pencils and infrared during the same visit. If you proceed with air sealing, we return for an after test and publish both numbers in your project file.
Thermal Imaging Inspection
Thermal imaging with a FLIR camera reveals temperature differences that indicate missing insulation, air leaks, or moisture intrusion. We scan ceilings, walls, and ductwork during the blower-door test when the pressure difference makes leaks visible. In Tustin homes with cathedral ceilings, which are common in the hillside builds near Peters Canyon, thermal imaging often shows gaps where insulation installers couldn’t reach or where batt insulation has settled away from the roof deck. The images become part of your Documented Photo Record, annotated with our notes on severity and repair priority.
Insulation Inspection
We measure existing insulation depth, check for compression or water damage, and identify thermal bypasses where air moves around or through the insulation. In Tustin, we find a lot of blown-in fiberglass that was installed over unsealed top plates and recessed can lights, which means the insulation is filtering air rather than stopping it. We check attic hatch seals, kneewall connections, and garage-ceiling junctions, all common weak points in local construction from the 1970s through the 2000s. Our report specifies what stays, what comes out, and what R-value target makes sense for your roof assembly and HVAC system.
Duct Leakage Test
The duct leakage test pressurizes your duct system and measures how much air escapes to the attic, crawl space, or wall cavities instead of reaching the rooms. In Tustin, where many homes have ductwork running through 140°F attics, a 20% leakage rate can add hundreds to summer cooling bills. We use a Duct Blaster fan and calibrated orifice to get a precise CFM25 reading, then smoke-test connections to find the specific leaks. The test takes about 45 minutes and often reveals that the biggest comfort complaints, hot rooms in summer or cold spots in winter, trace back to duct issues rather than insulation.

Brands We Service for Home Energy Audit
We’ve worked with insulation systems from Johns Manville, Knauf, and Rockwool across thousands of Tustin-area homes. With Johns Manville, we regularly assess their Spider blown-in fiberglass systems, which require specific density checks to achieve labeled R-values. Our crews know the installation tolerances and can identify when an existing JM job was underblown or missed critical edge details. Knauf’s EcoFill and Jet Stream products are common in local attics, and we check for their characteristic gray color and proper settling behavior during inspections. Rockwool’s stone wool batts, often found in Tustin’s newer construction and homeowner-installed projects, need careful examination for gaps at framing and compression at electrical boxes.
We also evaluate systems from CertainTeed and other major manufacturers with equal thoroughness. Whether your home has Owens Corning, Icynene spray foam, or an unknown material installed by a previous owner, we identify it, assess its condition, and specify what needs to change. No proprietary lock-in means our recommendations follow the building science, not a brand contract.
Before
AfterSigns You Need Home Energy Audit Right Now
- Rooms that stay hot in summer or cold in winter no matter what the thermostat says. This usually means conditioned air is escaping or never arriving, and in Tustin’s inland climate, the problem gets worse every year as ducts deteriorate in attic heat. An energy audit pinpoints whether the issue is duct leakage, missing insulation, or both.
- Energy bills that spike in July and August beyond what neighbors report. If your summer electric bills run 30-50% higher than similarly sized homes in Tustin Ranch or Laurelwood, your building envelope is working against your air conditioner. The audit quantifies exactly how much air you’re losing and what fixes pay back fastest.
- Dust that returns quickly after cleaning, especially near ceiling vents. This often indicates leaks in return ductwork that pull attic air through fiberglass insulation, carrying particulates into your living space. In older Tustin neighborhoods with original ductwork, we’ve measured return leakage above 15% on homes where homeowners had no idea.
- Ice damming or moisture staining at ceiling edges in winter. Even in mild Tustin winters, poor attic air sealing allows warm, moist interior air to hit cold roof sheathing, causing condensation and potential mold. The blower-door test and thermal imaging find the pathways that batt insulation alone cannot stop.
- Planning to add insulation without knowing current air leakage. This is the most expensive mistake we see. Blowing new insulation over an unsealed attic floor buries the leaks, makes them harder to fix later, and often reduces the new insulation’s effective R-value by 30% or more. We will not install insulation without first sealing, and the audit proves why.
Our Home Energy Audit Process - Step by Step
- 1
Schedule and written price. Call (657) 286-7673 or text us. We confirm your address in Tustin, ask about your home’s age, size, and specific complaints, then email a flat price for the audit before we arrive. No range that balloons, no “starting at” that never starts there. Haven Standard Clause 1: written price, written scope, written warranty before anyone lifts a tool.
- 2
Arrival and walkthrough. Your technician calls or texts when en route. We arrive in a marked vehicle, uniformed, and start with a 10-minute conversation about what you’ve noticed, any prior energy work, and your goals. In Tustin, we often learn about recent solar installations, room additions, or HOA requirements that affect what we can recommend.
- 3
Diagnostic testing. We run the blower-door test, thermal imaging scan, insulation inspection, and duct leakage test in sequence, typically over 2.5-3 hours for a single-family home. You can follow along; we explain what we’re seeing in real time. The smoke pencil tracing air leaks through a recessed can light is usually the moment homeowners understand why their bills are high.
- 4
Same-day findings review. Before we pack up, we show you the thermal images, explain the blower-door and duct leakage numbers, and rank recommendations by cost and impact. No waiting for a report that arrives three days later with pressure to buy. You’ll know whether air sealing, duct repair, insulation replacement, or some combination makes sense for your budget.
- 5
Written report and documented record. Within 24 hours, you receive a PDF with all photos, test readings, prioritized recommendations, and flat pricing for any follow-on work. If you proceed, this becomes the baseline for your before-and-after comparison. Every client gets this; nothing is held back or “available on request.”
How Much Does Home Energy Audit Cost in Tustin?
A standard home energy audit in Tustin runs $350-$550 for homes under 2,500 square feet, and $500-$650 for larger homes or those with multiple HVAC zones, so you know how much Home Energy Audit costs upfront. The base audit includes blower-door test, thermal imaging, insulation inspection, and written report. Adding a full duct leakage test typically adds $150-$250, though we often bundle this at reduced cost when both services are scheduled together.
Several factors move the price within these ranges. Homes built before 1985 in Tustin usually take longer to test because there are more leaks to trace and document. Multiple attic accesses, detached guest houses, or conditioned crawl spaces add complexity. If you need expedited scheduling, same-week appointments are available at standard rates, not premium surcharges.
What affects the price most is scope clarity. Some Tustin homeowners come to us with a previous energy audit or contractor quote; we offer a Free Second Opinion on any written estimate, which sometimes reveals that prior testing was incomplete or recommendations were misaligned with the actual findings. Our audit price includes everything, no trip charges or report fees added later.
To avoid overpaying, verify that any auditor you consider uses a calibrated blower door (not a homemade rig), provides actual CFM50 numbers (not pass/fail), and includes thermal imaging in the base price rather than as an upsell. Ask for sample reports before booking. Under The Haven Standard, we’ll show you a redacted report from a comparable Tustin home so you know exactly what leaving looks like.
