Trusted Home Energy Audit for Pomona Homeowners
A home energy audit in Pomona typically costs between $199 and $499 for a comprehensive whole-house assessment that includes blower door testing, thermal imaging, and a detailed report. Most homeowners schedule an audit because their utility bills keep climbing while certain rooms stay stubbornly uncomfortable, and they want answers instead of guesswork. Our team at Warmline Insulation Co. has performed audits across Pomona since 2011, which means we know exactly how Pomona’s hot inland summers and older housing stock combine to create energy leaks that newer homes don’t deal with.
We’re a full-spectrum insulation and home-performance contractor, not a utility-company subcontractor running a basic checklist. When you call home energy specialists at (626) 341-0830, a live person answers 24/7, and we can usually schedule your audit within the same week. The audit is the diagnostic starting point that makes every insulation or air-sealing decision smarter and more targeted, so you’re never paying for work your house doesn’t actually need.
What Our Home Energy Audit Service Includes
Blower Door Test
A blower door test measures exactly how much air leaks through your home’s exterior shell, using a calibrated fan mounted in an exterior door frame to depressurize the house and quantify leaks in cubic feet per minute. In Pomona, where summer temperatures routinely exceed 95°F, we often find that older 1960s and 1970s tract homes in the Phillips Ranch and Westmont neighborhoods leak two to three times more air than a modern energy-code home. Neil Ashford and our technicians run the test, read the digital manometer data, and translate those numbers into plain language: here’s where the air is escaping, here’s what it’s costing you per year, and here’s what stopping it would take. Without a blower door number as your baseline, any insulation quote you get is just a guess.
Thermal Imaging Inspection
Thermal imaging uses an infrared camera to show surface temperature differences that reveal missing, settled, or water-damaged insulation inside walls, ceilings, and floors without opening up any drywall. We run this camera during the audit because it catches problems the naked eye can’t, especially in Pomona’s stucco-and-plaster older homes where insulation gaps hide behind lath and plaster that looks fine from the outside. When we scan a ceiling and see cold stripes between joists, we know insulation settled or was never installed properly in the first place. This is the tool that turns a vague “my bedroom is always hot” into a specific, visible diagnosis on the camera screen.
Insulation Inspection
An insulation inspection covers every accessible space: the attic floor, crawl space rim joists, exterior walls where possible, and the garage ceiling. In Pomona, we routinely see attics with R-19 fiberglass that’s been walked on, compressed, and rodent-nested for 30 years, performing closer to R-9 or worse. We document the type, depth, condition, and coverage of whatever insulation is present, then compare it to what the Department of Energy recommends for your climate zone so you know exactly where you stand. If the insulation is damp, moldy, or contaminated, we’ll tell you and recommend Home Energy Audit in La Puente-style removal and replacement before you spend money sealing in a problem.
Duct Leakage Test
A duct leakage test pressurizes your duct system and measures how much conditioned air escapes into the attic or crawl space before it ever reaches your living areas. In Pomona, many HVAC systems run ductwork through hot attics, and we commonly find 20 to 30 percent of the air you’re paying to cool leaking into spaces nobody lives in. Our technicians use a duct blaster or pressure-pan testing to quantify the loss, which matters because fixing duct leaks often delivers faster payback than adding insulation to the attic itself. The test also helps us spot disconnected ducts, crushed flex runs, and poorly sealed register boxes.

Brands We Service for Home Energy Audit
When we perform a home energy audit in Pomona, we’re evaluating the entire building envelope, which means we assess insulation from every major manufacturer, including CertainTeed fiberglass and GreenFiber blown-in cellulose. Our technicians know how CertainTeed batts perform after a decade in a Pomona attic, how they settle, and how their R-value holds up compared to the printed spec. We’ve also audited hundreds of homes with GreenFiber cellulose installed in attics and walls, and we know exactly what proper coverage looks like versus a thin, under-blown job that fails to deliver its rated performance.
For homes with spray foam, we’re familiar with Icynene open-cell and closed-cell applications and can evaluate whether the foam was installed at the correct depth and density. Whether your Pomona home has CertainTeed, GreenFiber, Icynene, or any other brand, the audit process works the same way: we measure, we test, we document, and we give you honest numbers. The brand matters less than the installation quality, and our audit reveals whether you got what you paid for.
Signs You Need Home Energy Audit Right Now
- Your energy bills keep rising while your usage habits haven’t changed. Pomona homeowners on Southern California Edison time-of-use plans feel every wasted kilowatt-hour acutely. If your summer bills hit $350 or more in a 1,500-square-foot home, you’re likely paying to condition air that leaks out within minutes.
- Some rooms are always 5 to 10 degrees hotter or colder than the rest of the house. The living room stays comfortable while the upstairs bedrooms bake. That temperature spread points to uneven insulation, duct leakage, or air sealing issues, and an audit pinpoints which one is the culprit before you spend money on the wrong fix.
- You feel drafts near windows, outlets, or baseboards in winter. Pomona winter nights drop into the 40s, and if you can feel air moving inside your home on a still evening, you have envelope leaks. Each small draft adds up to the equivalent of leaving a window cracked 24 hours a day.
- Your attic insulation looks thin, matted, or dirty. If you’ve been up in the attic and the insulation barely covers the joists, or it’s compacted from years of foot traffic and rodents, it’s not doing its job. An audit quantifies the loss and tells you what R-value you actually need for Pomona’s climate.
- Dust, musty smells, or pests keep coming back no matter what you do. Air leaks don’t just waste energy; they carry dust, moisture, and rodent traffic into your living space. If you’ve sealed cracks and set traps but the problems return, the building envelope itself is the likely access point, and Home Energy Audit in Irwindale homeowners report the same pattern.
Our Home Energy Audit Process - Step by Step
- 1
Walkthrough and homeowner interview. We start by walking your Pomona home with you, inside and out, asking about the specific comfort complaints, bill history, and any issues you’ve noticed like drafts, hot rooms, or moisture. This gives us a map of where to focus testing and what your priorities are, not just what our instruments find.
- 2
Blower door and pressure testing. We set up the calibrated blower door in an exterior doorway, depressurize the house, and record the air leakage rate in CFM50. We also use a pressure gauge to evaluate how connected your attic, crawl space, and living areas are to each other, which matters because air follows the path of least resistance regardless of what you paid to insulate.
- 3
Infrared scanning and insulation assessment. With the house depressurized, we run the thermal imaging camera across walls, ceilings, floors, and around windows and doors. The negative pressure pulls outside air through every gap, making leaks show up clearly on the infrared scan as hot or cold streaks. We also inspect and measure insulation depth and condition in the attic, crawl space, and any other accessible cavities.
- 4
Duct leakage testing and combustion safety check. We pressurize the duct system to quantify conditioned air loss, then inspect the furnace or water heater area for proper combustion air and backdrafting risk. This step is easy to skip but important in Pomona’s older homes, where sealed-up rooms and aging gas appliances can create real carbon monoxide risks.
- 5
Report, recommendations, and honest numbers. Before we leave, we sit down with you and walk through what we found: the leakage numbers, the infrared photos, the insulation deficiencies, and the duct losses. We give you a prioritized list of fixes with estimated payback periods so you can decide what to tackle first, and there’s no pressure to buy anything from us afterward.
How Much Does Home Energy Audit Cost in Pomona?
Several factors move the price up or down: square footage, number of floors, accessibility of the attic and crawl space, and whether you want comprehensive duct testing included. The smart way to avoid overpaying is to bundle the audit with other work we already perform, like attic air sealing or Home Energy Audit in Pomona recommendations we can implement immediately.
