Optimizing a Comfortable, Healthy, and Efficient Home 

• It measures your home’s total air leakage: The test tells us exactly how drafty your house is. This allows us to precisely target our air-sealing efforts to make your living spaces more comfortable, healthy, and energy-efficient.

• We use precision diagnostic equipment: We temporarily fit a sealed, temporary canvas frame and a calibrated diagnostic fan into one of your exterior doorways.

• It forces hidden drafts to show themselves: When the fan runs, it gently pulls air out of the house to lower the indoor air pressure. This forces outside air to rush in through every hidden gap, crack, and hole. By pairing the fan with specialized tools like infrared cameras or smoke indicators, we can pinpoint exactly where your expensive conditioned air is escaping and where dusty attic or crawlspace air is sneaking in.

• We calculate the total size of your home's leaks: By measuring the exact amount of air the fan must move to maintain that pressure, we can calculate your home's total leakage area. Imagine trying to blow up a balloon with hundreds of pinholes in it; that’s exactly what your heating and cooling system is fighting against every day if your home is leaky.

• We use this data to protect your indoor air quality: This data reveals exactly where your home's thermal and air barriers aren't lining up. More importantly, it allows us to safely calculate your home's fresh air requirements in accordance with national indoor air quality standards (ASHRAE 62.2). This ensures that while we make your home tight and efficient, we also keep it properly ventilated so the air you breathe stays fresh and safe.

• It isolates hidden energy losses: In the greater Los Angeles area, typical homes can lose up to 20% or more of their conditioned air through hidden rips, gaps, and disconnected seams in the ductwork. This test reveals exactly how much of your heated or cooled air is actually reaching your living spaces.

• We temporarily seal your system: To perform the test, we temporarily seal off all your supply registers with a specialized, non-damaging wrap. This closes the system to measure its integrity.

• We use a calibrated diagnostic fan: We connect a specialized, high-precision diagnostic fan to your central air handler or return grill. This fan gently pressurizes your ductwork with air to see how well the system holds that pressure.

• It quantifies the exact waste: By measuring how much air escaping through the cracks it takes to keep the ducts pressurized, the system calculates your total duct leakage. This tells us exactly whether your system is performing efficiently or just wasting your money heating and cooling your attic or crawlspace.

• It ensures healthier indoor air: Leaky ducts don't just let conditioned air out; they also draw in dirty, dusty air from your attic or crawlspace when the system turns on. Finding and sealing these leaks keeps your HVAC system running smoothly and dramatically improves your home's indoor air quality.

It maps heat patterns inside your walls: Using a high-precision FLIR B-51 thermal imaging camera, we analyze the surface temperatures of your walls and ceilings. This allows us to see variations in heat transfer, helping us identify missing insulation or structural flaws without touching your drywall.

It relies on strict physics, not parlor tricks: To get an accurate thermal image, the camera requires a "Delta T," which is simply a noticeable temperature difference between the inside of your house and the outside world. In our mild Southern California climate, indoor and outdoor temperatures often equalize, and shaded walls can hide defects. Because we are committed to absolute diagnostic accuracy, we only interpret thermal data when the laws of physics allow us to guarantee valid results.

We artificially condition your home for crystal-clear results: To overcome mild local weather and eliminate shaded-wall blind spots, we often have you run your heating or cooling system to "pre-condition" the house before the test. By artificially forcing a strong temperature difference between the inside and outside, we cause hidden flaws to stand out in high contrast. This extra step helps you get a highly accurate, flawless thermal map of your insulation and framing.

It catches hidden air leaks when paired with our blower door: When the temperature is set, we run our diagnostic fan to pull outdoor air through hidden wall cavities. The FLIR camera captures the exact paths where dusty, unconditioned attic or outdoor air is sneaking into your home behind your baseboards and outlets.

It helps protect your indoor air quality: By pinpointing where your home's air and thermal barriers are failing, we can prevent dust buildup on walls, eliminate drafts, and seal pathways that let outdoor allergens and moisture in.

• A Flash Test is like taking your home's temperature with a fast digital thermometer.

• In about 30 minutes, we can get an immediate baseline reading of what you are breathing right that second.

• It's a fantastic, low-cost way to immediately detect elevated concentrations of fine particulate matter (PM2.5), Total Volatile Organic Compounds (TVOCs), Formaldehyde, and carbon dioxide (CO2). 

• It gives us an instant snapshot, so we know whether your home needs immediate triage or we need to dig deeper.

• We place the specialized AirAdvice indoor air analyzer in your living space for a full workweek or weekend while your family lives normally.

• Air quality changes constantly—it spikes when you cook breakfast, dips when the AC cycles on, and changes when everyone is sleeping with the bedroom doors closed.

• By tracking your air 24 hours a day for 5 days, we see the exact patterns, habits, and building flaws that a quick test would completely miss.

• Think of a Flash Test as a quick photo of your air quality. The 5-Day Test is a complete, continuous recording. While the quick test highlights if an issue exists, our 5-Day Test uses the AirAdvice analyzer to uncover the hidden patterns—giving us the data we need to fix it right the first time.
