Indoor air quality is important in the Greater Houston area for several reasons:
Poor indoor air quality can lead to a range of health problems, including respiratory issues, headaches, fatigue, and allergies. It can also exacerbate existing health conditions such as asthma and heart disease. Therefore, improving indoor air quality in the Greater Houston area is important for maintaining the health and wellbeing of its residents.
At Texcellent A/C Service, we believe that effective solutions begin with accurate diagnostics. Before recommending any indoor air quality improvement, we deploy comprehensive testing and analysis to identify the true root causes of comfort, health, and efficiency issues. Our team holds certifications from the Building Performance Institute (BPI) and the National Comfort Institute (NCI), enabling us to perform industry-leading diagnostics. This data-driven approach ensures that every recommendation we make is tailored to your home's specific needs—not guesswork or one-size-fits-all solutions.
Texcellent A/C service is BPI-Certified to perform blower door testing — the gold standard for measuring a home's airtightness. Using precision-calibrated equipment, we can identify where air leaks are occurring, how much infiltration is happening, and how it's impacting comfort, humidity, and energy efficiency. This test allows us to pinpoint loss points invisible to the eye, from recessed lights to framing gaps, and helps determine the most effective path toward true system performance.
Blower door testing isn't guesswork — it's science. By quantifying leakage rates, we help our clients make informed decisions about air sealing, ventilation, and HVAC sizing to achieve balanced, healthy indoor environments.
Duct leakage and uncontrolled air infiltration are two of the biggest contributors to energy loss, poor humidity control, and uneven comfort. Texcellent is BPI-Certified in both infiltration and duct leakage testing — meaning we use industry-standard pressure diagnostics to measure exactly how much air is escaping through your ductwork or entering through your building shell.
These tests allow us to calculate true system performance, rather than relying on assumptions. By sealing, balancing, and verifying results, we ensure your HVAC system delivers the airflow and efficiency it was designed for — not what's left over after leaks.
As an NCI-Certified Residential Air Balancer, Texcellent's approach to comfort is built on design, data, and discipline. Proper air balance is about much more than "feeling air at the vents." It's about ensuring the system moves the right volume of air, at the right velocity, to the right locations — every time.
Through static pressure mapping, fan performance verification, and detailed duct system optimization, we identify and correct the root causes of poor airflow, temperature differences, and noise. Our NCI certification ensures we follow proven balancing protocols used by the nation's top performance contractors — not guesswork or shortcuts.
Accurate heating and cooling design begins with accurate data. Texcellent performs in-house load calculations using ConduitTech, and we partner with trusted third-party engineering firms for full, formal Manual J, D, S, and T designs when required. These calculations are the blueprint for correct equipment selection, duct sizing, and air distribution — critical steps often skipped in standard HVAC replacements.
Proper design ensures that every ton of capacity is used efficiently, preventing oversizing, short cycling, and humidity issues. At Texcellent, design integrity comes first — because precision on paper leads to comfort in reality.
Using the TEC TrueFlow Grid, Texcellent technicians measure actual airflow through the air handler or furnace — not an estimate or assumption. This diagnostic tool replaces the filter temporarily and provides direct CFM readings to verify if the system is moving the air it's designed to.
This data allows us to identify restrictions, undersized returns, or failing blower performance in minutes. When paired with MeasureQuick analysis, TrueFlow testing gives a complete picture of real-world system performance — helping ensure your investment is delivering peak efficiency and comfort.
Zonal pressure testing measures how different areas of a home interact with the HVAC system and the building envelope. By analyzing pressure imbalances between rooms, attics, and crawlspaces, Texcellent can identify hidden duct leaks, return air restrictions, or envelope breaches that disrupt comfort and energy balance.
This advanced testing helps us fine-tune airflow, improve indoor air quality, and reduce unwanted air exchange with attics or garages — all critical for maintaining clean, conditioned indoor air.
Some leaks can't be seen until they're visualized. Using professional smoke tracing tools, Texcellent technicians can physically show how air moves through leaks, cracks, and duct connections. It's one of the most effective methods for demonstrating hidden airflow pathways and validating repairs.
Smoke tracing turns invisible building flaws into visible results — giving clients peace of mind and helping our team confirm that every seal, joint, and connection is performing as intended.
With advanced infrared thermal imaging, Texcellent identifies insulation voids, duct losses, radiant heat intrusion, and moisture-related thermal anomalies that standard inspections miss. These color-mapped scans reveal temperature differentials in walls, ceilings, and ductwork, helping us diagnose comfort issues at their source.
Thermal imaging is particularly valuable for validating repairs, locating bypasses, and verifying system performance under real-world conditions. It's precision craftsmanship — made visible.
Building forensic diagnostics is where Texcellent's high-performance HVAC expertise meets building science. Our team uses a combination of pressure mapping, thermal imaging, and airflow verification to uncover hidden issues within the structure itself — from trapped moisture and air bypasses to envelope weaknesses affecting system performance.
Rather than replacing equipment blindly, we investigate the entire building as a system — ensuring solutions are holistic, durable, and effective. This approach protects the investment, the structure, and the people living within it.
True comfort isn't achieved by equipment alone. Texcellent's Building Performance Testing evaluates how the entire home functions as an integrated system — HVAC, ductwork, insulation, windows, and envelope all working together.
By testing and verifying rather than guessing, we can deliver quantifiable improvements in efficiency, comfort, and air quality. Whether it's a new build, retrofit, or high-performance remodel, our testing ensures every project meets our PEAC Standards of Professionalism, Expertise, Accuracy, and Craftsmanship.
Texcellent utilizes MeasureQuick, an advanced cloud-based diagnostic platform that captures live system performance data from connected tools and sensors. This technology allows us to analyze refrigerant charge, airflow, temperatures, and pressures simultaneously — giving a true picture of how your system performs under real conditions.
With MeasureQuick, our technicians can detect efficiency losses, improper setup, or underlying design issues faster and more accurately than traditional testing. It's part of how we deliver verifiable results — ensuring your HVAC system performs as engineered, not just as installed.
