Trusted Home Energy Audit for Long Beach Homeowners
A home energy audit in Long Beach typically costs between $250 and $600 and takes two to four hours, depending on the home’s size and how many diagnostic tests you want included. The audit pinpoints exactly where your conditioned air is leaking out and where heat is sneaking in, so you’re not guessing when it comes time to fix things. At Summit Insulation Long Beach, Nate Calloway runs the audit himself and walks you through every finding while he’s still standing in your house. Call (562) 784-9031 to schedule yours.
Long Beach homes have a specific problem set. Salt air works on ductwork in crawl spaces. Afternoon sun beats on attics in neighborhoods from Belmont Shore to Bixby Knolls. Older Craftsman bungalows in Rose Park leak air through original framing, while mid-century homes in Los Altos often have insulation that’s settled to half its original R-value. A real audit measures these problems rather than guessing at them. We’ve performed audits across Long Beach, Lakewood, Signal Hill, and Bellflower, and the same patterns show up: uneven room temperatures, high summer cooling bills, attics that feel like an oven by 3 p.m. Nate uses blower door equipment and thermal imaging to show you exactly where your home’s thermal envelope is failing. If you want to understand why your upstairs is ten degrees warmer than your living room, start home with a proper diagnostic, not a sales pitch.
What Our Home Energy Audit Service Includes
Every audit we perform in Long Beach is built around four diagnostic tests that together give a complete picture of how your home’s thermal envelope is performing. None of these are optional add-ons we use to pad the bill. They’re the core of the service, and each one answers a specific question about where your energy dollars are going.
Blower Door Test
A blower door test measures precisely how much air leaks through your home’s shell: windows, doors, wall penetrations, recessed lights, attic hatches, and sill plates. A calibrated fan mounts into an exterior door frame and depressurizes the house, which lets us quantify your total air leakage in cubic feet per minute. Most Long Beach homes built before 1980 leak at two to three times the rate recommended by current building codes. When we run this test, you’ll actually feel air moving through the gaps in real time, which makes the findings hard to ignore. Nate then uses the blower door numbers to size your air sealing scope correctly rather than guessing.
Thermal Imaging Inspection
Thermal imaging is how we find the leaks and gaps a visual inspection alone will never catch. An infrared camera shows temperature differences across wall cavities, ceilings, and floors, revealing where insulation has settled, been pulled back, or is missing entirely. In Long Beach’s summer heat, this is particularly useful for identifying radiant heat gain coming through poorly insulated attic spaces. After the blower door depressurizes the house, the thermal camera makes air leaks visible as dramatic color shifts. We’ll walk you through the images on the spot so you’re seeing the same evidence we’re seeing.
Insulation Inspection
This is a hands-on inspection of every accessible area of your attic, crawl space, and exterior walls. We measure actual insulation depth with a ruler rather than approximating, check for compression, moisture damage, pest contamination, and voids around electrical and plumbing penetrations. In Long Beach, we commonly find insulation that was installed correctly but has since been damaged by rodents or compacted by decades of foot traffic from HVAC techs and cable installers. We’ll tell you the current R-value of what’s in place and what the Department of Energy recommends for our climate zone. If the insulation is contaminated or degraded, that affects your air quality too, not just your comfort.
Duct Leakage Test
A duct leakage test measures how much conditioned air escapes from your duct system before it ever reaches your living spaces. We use a duct blaster to pressurize the system and calculate leakage as a percentage of total airflow. The national average is around 20 to 30 percent leakage, which means a quarter or more of the air you’re paying to heat or cool never makes it to the rooms you’re trying to condition. In Long Beach homes with ductwork running through hot attics or damp crawl spaces, this test often reveals the single biggest energy waste point in the entire house. Once we know the number, we can prioritize duct sealing as part of your whole-home plan.

Brands We Service for Home Energy Audit
When we inspect insulation during an energy audit in Long Beach, we’re evaluating materials from manufacturers we install and service daily. We work with Owens Corning fiberglass, Rockwool mineral wool, Icynene and Demilec spray foam, and GreenFiber cellulose. That matters because we know what correct installation of each material looks like, how it should perform over time, and what failure patterns develop. An audit that spots three inches of settled GreenFiber in a Long Beach attic needs an inspector who knows what GreenFiber’s settled density should be, not someone reading a chart off the internet.
During your audit, we’ll identify whatever insulation is currently in place, regardless of brand, and tell you honestly whether it’s doing its job. If you have Icynene open-cell foam that’s pulled away from the roof deck or Demilec closed-cell foam that was never sprayed to proper depth, we’ll catch it. The brand portfolio matters at the recommendation stage too. If you need a radiant barrier installed alongside new insulation, we’ll specify the right product pairing rather than defaulting to whatever’s cheapest. Whether you have Owens Corning batts, Rockwool, or an unknown material from the 1960s, we’ll give you the same direct assessment.
Signs You Need a Home Energy Audit Right Now
- Your upstairs rooms are 8 to 10 degrees hotter than downstairs. In Long Beach, this is the most common complaint we hear from homeowners in the summer, and it’s almost never an HVAC sizing problem. Heat rises and collects in your attic, and when your attic insulation is thin or uneven, that heat radiates through bedroom ceilings all afternoon. An audit shows us exactly which ceiling cavities are affected before you spend money on a new AC unit that won’t fix the underlying issue.
- Your energy bills have climbed 20 percent or more year over year. SoCal Edison and Long Beach Gas & Oil rates have gone up, but a sustained jump usually signals something changed inside your home’s thermal envelope. Compromised insulation, new air leaks, or duct separation in a crawl space after recent plumbing or pest work will all push your usage up. A blower door and duct leakage test will find the smoking gun in an afternoon instead of leaving you to guess.
- You’ve seen evidence of rodents or pests in the attic. Rats and squirrels destroy insulation. They tunnel through it, nest in it, and contaminate it with urine and droppings, and that damage is not always visible from the attic hatch. If you’ve heard scratching overhead at night in neighborhoods like Naples or El Dorado Park, an insulation inspection should happen before you spend another dollar on trapping alone. New insulation over a contaminated substrate is money thrown away.
- Certain rooms stay cold in winter no matter where you set the thermostat. This is often a perimeter leak problem: missing insulation at the rim joist, unsealed electrical penetrations, or a crawl space that’s acting as a direct conduit for outside air into your floor system. Homes near the water in Long Beach get hit harder by this because the temperature differential between the crawl space and your living space is so pronounced. A thermal imaging scan pinpoints these cold zones in minutes.
- You can feel drafts around windows, outlets, or baseboards on windy days. Long Beach gets reliable afternoon breezes off the ocean, and on days when the wind picks up, air infiltration becomes obvious if you know what to look for. Drafts around electrical outlets and baseboards indicate air is moving through your wall cavities, which means your wall insulation isn’t stopping the flow. A blower door test on a windy day is one of the most revealing diagnostics you can run on an older Long Beach home.
Our Home Energy Audit Process — Step by Step
We keep the process straightforward. No jargon, no pressure, and you’ll understand every finding before we leave. Here’s what to expect when you schedule our Home Energy Audit in Long Beach.
- 1
Initial walkthrough and interview. Nate starts by asking about the specific problems you’ve noticed: which rooms are uncomfortable, what your bills look like, whether you’ve had pest or moisture issues. Then he walks the entire property with you, inside and out, looking at the building orientation, window placement, roof condition, and access points to the attic and crawl space. This conversation often reveals issues you didn’t realize were connected, like a bathroom vent dumping humid air into your attic.
- 2
Blower door test and pressure diagnostics. We set up the blower door in an exterior doorway and depressurize the house to a standard 50 pascals of pressure. This gives us a baseline air leakage number in CFM50, which we compare against building science benchmarks for your home’s size and age. With the house depressurized, air leaks become physically detectable by hand and with a smoke pencil, so we start marking problem areas immediately.
- 3
Thermal imaging scan. With the house still under negative pressure, Nate scans every wall, ceiling, and floor surface with an infrared camera. This is where missing insulation, thermal bridging, and hidden air pathways show up in vivid color. He’ll take images of every problem area so you have documentation of exactly what’s wrong and where.
- 4
Attic, crawl space, and duct inspection. Nate goes into the spaces most contractors won’t. He measures insulation depth and condition, checks for moisture and pest damage, examines duct connections and sealing, and evaluates ventilation. In Long Beach, salt air corrosion on duct straps and supports is common, especially in older crawl spaces near the coast. If there’s a problem in these spaces, this is when it gets documented.
- 5
Findings review and prioritized recommendations. Before we pack up, we sit down with you and go through everything. You get a clear breakdown of what we found, what it means for your comfort and utility bills, and what we’d fix first. There’s no hard sell, only a ranked list based on impact per dollar. Most homeowners tell us this is the most valuable part of the entire audit.

How Much Does Home Energy Audit Cost in Long Beach?
A comprehensive home energy audit in Long Beach, including blower door testing, thermal imaging, insulation inspection, and duct leakage testing, typically runs between $400 and $600 depending on home size and access complexity. If you’re only interested in a specific test, say a thermal imaging scan or an insulation inspection, expect to pay between $150 and $250. Homes over 3,000 square feet or with difficult crawl space access tend to fall at the higher end of these ranges, while single-story homes under 1,500 square feet usually land at the lower end.
What affects the price most is the number of diagnostic tests you want and the complexity of your home’s construction. Older Long Beach homes with multiple additions, sloped attic spaces, or obstructed crawl spaces take longer to inspect thoroughly. Some companies will quote you a rock-bottom audit price and then try to make it back on inflated remediation bids. That’s not how we work. Our estimates are free, and if we find problems you decide to fix with us, the audit cost is credited toward the remediation work. Call (562) 784-9031 and Nate will give you an exact price for your home before we schedule anything.

Frequently Asked Questions — Home Energy Audit in Long Beach
A home energy audit is a systematic diagnostic evaluation of how your home uses and loses energy. It combines blower door testing, thermal imaging, insulation inspection, and duct leakage testing to measure exactly where conditioned air is escaping and where outdoor heat or cold is infiltrating. At the end, you get a prioritized list of fixes with specific measurements behind each recommendation, not vague suggestions. The audit turns your home’s energy performance from a mystery into hard numbers you can act on.
A complete home energy audit in Long Beach takes between two and four hours depending on the home’s size and how many problem areas we find. Single-story homes under 1,500 square feet are usually done in two to three hours. Larger homes, multi-story properties, or homes with extensive crawl spaces and duct runs can take four hours or more. We’ll give you a time estimate when you schedule.
A full diagnostic audit in Long Beach ranges from $400 to $600, while individual tests like thermal imaging alone run $150 to $250. The exact price depends on square footage, number of tests, and access difficulty. Our estimates are always free and come with a specific number before any work is scheduled, plus the audit cost gets credited toward any remediation work you have us perform. Call (562) 784-9031 for a price on your specific home.
Yes, we inspect and evaluate spray foam insulation from Icynene and Demilec regularly. We know what proper installation depth and coverage looks like for both open-cell and closed-cell applications, and we can spot installation flaws like shrinkage, off-ratio foam, or incomplete coverage. If your spray foam is in good shape, we’ll tell you that too. Our audit recommendations are based on your home’s actual condition, not on upselling you into replacing perfectly good insulation.
Yes, in many cases we can. If you’re dealing with an urgent issue like severe drafts after storm damage, suspected gas intrusion through your crawl space, or active rodent activity in your attic, we’ll prioritize your audit. Call (562) 784-9031 and tell us what’s going on. Nate will let you know if he can get to you same-day or next morning in most of our Long Beach service area.
Our audit findings are documented with thermal images, pressure measurements, and written reports, and we stand behind the accuracy of our diagnostics.
