Most HVAC companies offer tune-ups. We engineer performance. This is not maintenance — this is engineering for how your home actually works in Grapevine, Southlake, and the DFW Mid-Cities.
Engineering-based diagnostics • Developed for North Texas climate • Real measurements, not guesses
The Comfort Audit™ was developed by Too Cool Air to replace guesswork and sales-driven inspections with measured, performance-based home diagnostics. While others may use the term, our process is defined by engineering, testing, and commissioning standards designed specifically for North Texas homes and climate conditions.
A traditional tune-up is like an oil change — it keeps the system running. A Comfort Audit™ is like a NASCAR pit stop for your entire home — measuring airflow, pressure, heat load, humidity, and system performance to optimize efficiency, comfort, and long-term reliability.
This is not maintenance. This is engineering for how Grapevine, Southlake, and DFW homes actually perform in the Texas heat and humidity.
One maintains equipment. The other engineers how your home performs.
Most HVAC companies guess at the problem. We measure it.
We measure static pressure, ΔT, airflow, and humidity with calibrated instruments specifically for North Texas conditions. You get a complete data sheet showing exactly what we found and what it means for your Grapevine or Southlake home.
When you proceed with recommended repairs or upgrades, your $89 audit fee is credited toward the work. No guesswork, no upselling — just data-driven solutions that make sense for your home and budget.
Often the issue is airflow, ductwork, or attic heat gain — not a new system. Our Comfort Audit™ identifies the actual problem in your DFW home, saving you thousands on unnecessary replacements.
Engineering standards developed specifically for North Texas climate and construction methods
Airflow restriction in your ductwork. Should be under 0.5 in-wc for optimal performance. High pressure means restricted airflow — common in Grapevine and Southlake homes with undersized returns or dirty coils.
Difference between return and supply air. Should be 16-22°F in cooling mode. Shows if your system is moving enough air to handle North Texas heat. Low ΔT often indicates airflow problems.
Indoor moisture levels. North Texas homes should maintain 45-55% RH. High humidity causes mold, discomfort, and increased cooling costs — especially critical during DFW summers.
Cubic feet per minute of air moving through your system. Should be 350-450 CFM per ton of cooling. We verify your system moves enough air to cool your home efficiently in Texas heat.
Evaluate attic conditions, insulation, duct leakage, and solar gain factors specific to your home orientation and construction. Critical for DFW homes where attic temperatures reach 150°F+.
Complete inspection of evaporator coil, condensate drain, electrical connections, refrigerant charge, thermostat calibration, and control sequence operation.
The Comfort Audit™ requires diagnostic equipment, training, and engineering standards most companies do not have
We measure static pressure (airflow restriction), temperature split (ΔT), relative humidity, and visually inspect all system components. These measurements tell us if your system is working efficiently or where problems exist.
The Comfort Audit™ was developed by Too Cool Air to replace guesswork and sales-driven inspections with measured, performance-based home diagnostics. While others may use the term, our process is defined by engineering, testing, and commissioning standards designed specifically for North Texas homes and climate conditions.
The $89 Comfort Audit fee is credited toward approved upgrades when you move forward with recommended repairs, upgrades, or installations.
Most audits take 1-2 hours. We take our time to get accurate measurements and explain everything we find.
No. Our techs are trained to diagnose first, not sell. If your system is fine, we will tell you. If it needs work, we will show you the data and explain your options.
