Trusted Home Energy Audit for Pomona Homeowners
A professional our Home Energy Audit in Pomona typically costs between $350 and $750 for a full assessment, and most are completed in a single visit with results delivered the same day. Our team at Topside Attic Insulation Pomona performs blower-door testing, thermal imaging, and duct-leakage diagnostics to pinpoint exactly where your conditioned air is escaping. We’ve sealed and insulated over 9,000 homes since 2016, and every audit begins with a written price before any work starts. Call (562) 242-7569 to schedule - we answer live, 24/7, and most Pomona appointments are available within 48 hours.
Pomona’s housing stock tells a specific story. The pre-war bungalows north of the 10 Freeway, the mid-century tract homes near Ganesha Hills, and the newer builds south of Mission Boulevard all face different envelope challenges. We’ve audited homes in Lincoln Park where original lath-and-plaster walls hid massive top-plate gaps, and houses in Phillips Ranch where builder-grade attic insulation had settled to R-19 or below. The common thread: homeowners were paying to heat and cool air that leaked out before it ever reached their living rooms. Our audits don’t guess - we measure. The blower-door test gives us a single number, in CFM50, that quantifies your home’s leakage rate. Then we use thermal imaging to map where that air is moving, and a duct-blaster to check whether your HVAC ducts are losing pressure in the attic or crawl space. You leave with photos, readings, and a written scope - not a sales pitch.
What Our Home Energy Audit Service Includes
Blower Door Test
A blower-door test is a pressurization measurement that shows, in one number, how much conditioned air your building envelope is losing. We mount a calibrated fan in an exterior door frame, depressurize the house to 50 Pascals, and read the airflow in cubic feet per minute - your CFM50 score. In Pomona, we regularly see scores above 4,000 CFM50 in homes built before 1980, which means the house is exchanging its entire volume of air with the outside every few minutes. At Topside Attic Insulation Pomona, we perform this test at the start of every audit and again after any air-sealing work so you can verify the improvement in your documented record. Most Pomona homeowners are surprised to learn their “drafty” feeling isn’t from windows but from attic bypasses and unsealed can lights.

Thermal Imaging Inspection
Thermal imaging - infrared thermography - lets us see temperature differences across walls, ceilings, and floors that the eye cannot detect. During a Pomona audit, we run the blower door while scanning with a FLIR camera to make hidden air leaks visible as cold or hot streaks. In the summer, we often find hot attic air pouring down unsealed chases into interior walls, especially in two-story homes near Downtown Pomona where balloon framing is common. Our technicians mark each anomaly with a photo and location note, then build a priority map for sealing. The thermal images become part of your Documented Photo Record, included on every visit at no extra charge.

Insulation Inspection
Insulation inspection means measuring what’s in place, identifying what’s missing, and checking for damage from moisture, pests, or compression. We use a probe to check depth and density across your attic floor, wall cavities where accessible, and crawl space perimeter. In Pomona’s older neighborhoods like Mayfair and Westmont, we find vermiculite insulation that needs tested before disturbance, and in newer areas like San Antonio Heights, we see batts installed with gaps at the eaves that defeat the R-value on the label. We also inspect for proper ventilation - soffit baffles, ridge vents, gable vents - because adding insulation without airflow can trap moisture and rot your roof deck. Our report specifies exactly what material, what depth, and what R-value target applies to each location.

Duct Leakage Test
A duct-leakage test, or duct-blaster test, pressurizes your HVAC duct system to measure how much air escapes before reaching your rooms. We seal the registers, connect a calibrated fan to the air handler, and measure leakage to the outside - attic, crawl space, or wall cavities - versus total system flow. In Pomona, where summer cooling loads are severe and many ducts run through 140-degree attics, leakage above 15% means you’re paying to cool your attic. We’ve tested homes in Charter Oak where 30% of conditioned air never reached a register. The test takes about 45 minutes and produces a hard number: your duct leakage at 25 Pascals, expressed as CFM25 or as a percentage of system airflow. If sealing is needed, we quote it in writing with before-and-after test targets.

Brands We Service for Home Energy Audit

Our audits evaluate insulation and air-sealing systems regardless of manufacturer, and we’ve worked extensively with products from CertainTeed, Icynene, and Demilec. CertainTeed’s fiberglass batts and blown-in systems are common in Pomona tract homes from the 1970s through 1990s; we know how to spot their settling patterns and whether the original installation met the labeled coverage chart. For Icynene open-cell spray foam, we inspect for proper expansion, trim quality, and whether the applicator achieved the specified thickness - common issues in custom builds near Home Energy Audit - Claremont where spray foam was specified but not always installed to spec. Demilec closed-cell foam appears in many commercial-to-residential conversions in Downtown Pomona, and we verify its adhesion to substrate and whether the ignition barrier was applied correctly per code.
We also evaluate GreenFiber cellulose installations, which we encounter frequently in energy-retrofit projects across the San Gabriel Valley. Cellulose settles differently than fiberglass, and its density affects both R-value and fire-retardant longevity. Whether your home has CertainTeed, Icynene, Demilec, GreenFiber, or any other make of insulation, we can assess its condition, measure its performance, and specify what needs to change. No proprietary lock-ins, no brand exclusions.
Before
AfterSigns You Need Home Energy Audit Right Now
- Your upstairs rooms are 8-12 degrees hotter than downstairs in July. This isn’t normal. In Pomona’s climate, where attic temperatures exceed 140 degrees, poor insulation and unsealed top plates create a thermal chimney that dumps heat into second-floor rooms. An audit pinpoints whether the fix is attic air sealing, duct leakage, or insufficient insulation depth.
- Your PG&E bill spikes every summer despite no change in thermostat setting. We’ve audited homes in Ganesha Hills where the homeowner’s cooling costs had doubled in five years. The culprit was usually a combination of settled insulation and duct leakage that developed gradually - invisible until measured. A blower-door test and duct-blaster reveal what changed.
- You feel drafts near outlets, baseboards, or can lights even with windows closed. These are telltale signs of attic bypasses, where conditioned air escapes into wall cavities and pulls outside air in through gaps. In balloon-framed homes near Lincoln Park, this pathway is direct from attic to basement. Thermal imaging makes it visible.
- Your HVAC runs constantly but never reaches set temperature. When the equipment is sized correctly, this almost always means the building envelope or duct system is leaking faster than the unit can compensate. We measure both and tell you which to fix first - because replacing a perfectly good furnace won’t help if your ducts are losing 25% of airflow.
- You’re planning insulation upgrades and want to do it right the first time. This is the most common reason Pomona homeowners call us. Under The Haven Standard, we never add insulation over an unsealed attic floor - it’s sealed first, then insulated, in that order. An audit before you hire any contractor gives you a written scope to compare bids against, and our Free Second Opinion applies to any written estimate you bring us.
Our Home Energy Audit Process - Step by Step

- 1
Schedule and confirm. Call (562) 242-7569 or text us - a live person answers 24/7. We confirm your Pomona address, ask about your specific concerns, and send a named technician with a text when they’re en route. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
- 2
Written price before any work starts. When our technician arrives, they review your concerns, walk the property, and present a flat price for the audit in writing. No work begins until you approve. This is Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool.
- 3
Blower-door test and thermal imaging. We set up the blower door, run the depressurization test, and record your baseline CFM50. With the house under pressure, we scan with thermal imaging to map leakage paths - top plates, can lights, chimney chases, duct boots, and rim joists. Every finding is photographed and location-noted.
- 4
Insulation and duct inspection. We probe attic insulation depth, inspect for moisture or pest damage, check ventilation pathways, and run the duct-blaster if ducts are accessible. In crawl spaces, we evaluate vapor barrier condition and perimeter sealing. All readings go into your documented record.
- 5
Results delivery and written scope. Same day, we present your findings: blower-door number, thermal images, insulation R-values, duct leakage percentage, and a prioritized scope of work with flat pricing for each phase. You leave with a Documented Photo Record, before-and-after blower-door targets if sealing is recommended, and our 365-Day Done Right Promise in writing. If it’s not done right, we make it right.
How Much Does Home Energy Audit Cost in Pomona?
A full home energy audit in Pomona typically runs $350-$750 depending on home size, accessibility, and which diagnostics you need - see how much Home Energy Audit costs for more detail. Here’s how that breaks down for common scenarios:
| Audit Type | Typical Range | Best For |
|---|---|---|
| Basic audit (blower door + thermal imaging + insulation inspection) | $350-$500 | Single-story homes under 1,800 sq ft |
| Full audit (basic + duct leakage test) | $450-$650 | Most Pomona homes with attic ductwork |
| Comprehensive audit (full + crawl space + combustion safety) | $550-$750 | Two-story homes, additions, or pre-1960 construction |
Several factors move the price within these ranges. Homes in San Antonio Heights or Ganesha Hills with complex rooflines take longer to scan and may need multiple thermal imaging passes. Crawl space access in older Pomona neighborhoods like Mayfair can be tight, adding time for safe entry and inspection. If you need combustion appliance zone testing for gas furnaces or water heaters, that’s additional safety equipment and setup.
To avoid overpaying, get the scope in writing before anyone starts. A legitimate audit specifies which tests are included, what equipment is used, and what documentation you’ll receive. We publish our before-and-after blower-door numbers on every applicable job so you can verify results, not just promises. Our estimate is free, includes all diagnostics in the quoted price, and comes with no obligation to hire us for follow-up work. Bring us a competing written estimate and we’ll apply our Free Second Opinion - we’ll read it with you line by line.

Frequently Asked Questions - Home Energy Audit in Pomona

A home energy audit is a diagnostic evaluation of your building envelope and HVAC systems using calibrated equipment to measure air leakage, insulation performance, and duct integrity. At Topside Attic Insulation Pomona, our standard audit includes a blower-door test, thermal imaging, insulation inspection, and optional duct-leakage testing - all documented with photos and written findings you keep. Most Pomona homeowners use the results to prioritize repairs, compare contractor bids, or verify that previous work actually performed as claimed.
A typical audit takes 2.5 to 4 hours depending on home size, accessibility, and whether duct testing is included. Single-story homes in Pomona’s older neighborhoods usually run shorter; two-story homes with crawl spaces and attic ductwork take longer. We schedule morning or afternoon blocks and deliver your written results before we leave. Call (562) 242-7569 for an exact time estimate based on your address - estimates are free.
Most full audits in Pomona run $350-$750 based on home size, test complexity, and accessibility. A basic blower-door and thermal imaging audit for a smaller home starts around $350; comprehensive testing with duct-blaster and crawl space inspection for larger or older homes reaches the upper end. We provide a flat written price before any work starts, and our Free Second Opinion applies to any competing written estimate you bring us.
Yes - we evaluate, inspect, and upgrade CertainTeed fiberglass and blown-in systems, which are common in Pomona homes built from the 1970s through 1990s.
