Comfort Audit™ — The Original Performance-Based Home Diagnostics System
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.
Why Choose a Comfort Audit™?
Most HVAC companies guess at the problem. We measure it.
Performance Engineering
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.
Investment Protection
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.
Find the Real Problem
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.
What We Measure
Engineering standards developed specifically for North Texas climate and construction methods.
Static Pressure
Airflow restriction in your ductwork. Should be under 0.5 in-wc for optimal performance. High pressure means restricted airflow — common in DFW homes.
Temperature Split (ΔT)
Difference between return and supply air. Should be 16-22°F in cooling mode. Shows if your system is moving enough air to handle DFW heat.
Relative Humidity
Indoor moisture levels. North Texas homes should maintain 45-55% RH. High humidity causes mold, discomfort, and increased cooling costs.
Airflow (CFM)
Cubic feet per minute of air moving through your system. Should be 350-450 CFM per ton of cooling.
Heat Load Analysis
Evaluate attic conditions, insulation, and solar gain factors specific to DFW homes where attic temperatures often reach 150°F+.
System Commissioning
Complete inspection of evaporator coil, condensate drain, electrical connections, refrigerant charge, and control sequence operation.
Traditional Tune-Up vs. Comfort Audit™
One maintains equipment. The other engineers how your home performs.
Traditional HVAC Tune-Up
- Checks refrigerant levels
- Changes filters
- Inspects components
- Does not measure system performance
- Does not diagnose comfort or efficiency problems
- Does not verify results after changes
Comfort Audit™ by Too Cool Air
- Measures airflow, pressure, heat load, and humidity
- Identifies energy loss and comfort failure points
- Engineers system-level solutions
- Verifies improvements after changes are made
- Designed for North Texas climate conditions
- Complete data sheet with actual measurements
Origin of the Comfort Audit™
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.
Why Most HVAC Companies Cannot Engineer This
The Comfort Audit™ requires diagnostic equipment, training, and engineering standards most companies do not have.
Professional Diagnostic Equipment
- Digital manometers for static pressure measurement
- Calibrated hygrometers for humidity testing
- High-precision thermometers for ΔT analysis
- Thermal imaging for heat loss identification
Engineering Standards & Training
- ACCA Manual D airflow calculations
- Psychrometric analysis training
- Building science principles for DFW climate
- System commissioning procedures

Common Questions
What exactly do you measure in a Comfort Audit?
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.
How is this different from what other HVAC companies offer?
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.
When is the $89 credited?
The $89 Comfort Audit fee is credited toward approved upgrades when you move forward with recommended repairs, upgrades, or installations.
How long does a Comfort Audit take?
Most audits take 1-2 hours. We take our time to get accurate measurements and explain everything we find.
Will you try to sell me something I don't need?
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.
