Comfort Audit™ — Performance-Based Home Diagnostics
Hot rooms, high humidity, weak airflow or rising energy bills are often symptoms of a larger system problem. A Comfort Audit measures how your HVAC system and home are actually performing before repairs or replacement are recommended.
1–2 hour appointment • Written findings • $89 credited toward approved work
Why Choose a Comfort Audit™?
Many standard service calls focus on individual components. A Comfort Audit evaluates system performance using actual measurements.
Performance Measurement
We measure static pressure, ΔT and relative humidity with calibrated instruments and record what we find. You get the readings from your own Grapevine or Southlake home, not a generic checklist.
Investment Protection
When you proceed with recommended repairs or upgrades, your $89 audit fee is credited toward approved work. The readings come first, so the recommendation can be explained rather than assumed.
Look at the Whole System
Often the restriction is airflow, ductwork or heat gain rather than the equipment itself — helping homeowners avoid unnecessary or premature replacement recommendations.
The audit is the field side of the Too Cool Air Diagnostic System — the same measure-first process behind our HVAC diagnostics in Texas. To see where the audit fits alongside repair, installation, maintenance and ductwork work, browse our complete heating and cooling services.
Every Comfort Audit Includes
These steps are performed on every $89 appointment.
Static-Pressure Testing
Many residential systems are designed around a maximum external static-pressure target near 0.5 in. w.c., but the correct target depends on the equipment manufacturer and system design.
Temperature Split (ΔT) Measurement
Cooling temperature split is interpreted alongside airflow, humidity, equipment type and manufacturer specifications; a common operating range is approximately 16–22°F.
Relative-Humidity Measurement
Many North Texas homes feel most comfortable around 45–55% relative humidity, although appropriate targets can vary by season, construction and occupant needs.
Visual Inspection of Accessible Components
We inspect the accessible parts of the system — coil, drain, filter, electrical connections and controls — and note what we can see.
Discussion of Reported Comfort Problems
Hot rooms, humidity, noise, long run times or rising bills. What you experience day to day guides where we look.
Documented Findings & Prioritized Recommendations
A system-performance assessment and documented findings, with recommendations separated into urgent corrections and optional improvements.
Performed When Indicated by the Home or Complaint
These are added when the initial readings or your comfort complaint point to them — they are not part of every visit.
Direct Airflow Measurement
Airflow targets depend on equipment design and humidity-control goals. Many systems operate around 350–450 CFM per ton, but the correct target must be evaluated for the specific equipment and home.
Duct-Performance Evaluation
Used when the pressure readings or comfort complaints point to the duct system rather than the equipment.
Attic and Insulation Observations
Used when attic conditions or insulation coverage may be adding load the system has to overcome.
Thermal Imaging
Used to help locate temperature differences and suspected heat-gain paths when the findings call for it.
Heat-Gain and Home-Performance Observations
Observations of solar gain, envelope and layout factors that affect how the home holds a set temperature.
Additional Electrical or Refrigerant-Performance Checks
Added when the initial readings suggest an electrical or refrigerant-side issue that needs further investigation.
Formal load calculations, detailed duct design and advanced testing may be recommended separately when the initial findings show they are needed. When the readings point at the duct system we move into airflow testing and balancing, and the ductwork and airflow guides explain what those corrections involve.
Traditional Tune-Up vs. Comfort Audit™
Two different jobs. One maintains equipment; the other measures how the system is performing.
Traditional HVAC Tune-Up
- Preventive equipment maintenance
- Electrical and mechanical inspection
- Drain and filter checks
- Seasonal operation review
- Best for equipment that is operating normally
If your system is running normally, see our HVAC maintenance options.
Comfort Audit™ by Too Cool Air
- Performance-based diagnostic service
- Static pressure, ΔT and humidity measurements
- Evaluation of airflow and comfort complaints
- Written findings and prioritized recommendations
- Best for hot rooms, humidity, weak airflow and recurring comfort problems
Sticky humidity is a common reason homeowners book one — the humidity and moisture guides cover why it happens in North Texas, and cool, damp conditions in tight spray foam homes are one version of it. The guide to evaluating heat-pump performance in North Texas explains how equipment, airflow, controls and moisture load interact. For filtration concerns, the guide to HEPA media, static pressure and filter bypass shows why the filter and blower must be evaluated as one system.
What You Receive After the Comfort Audit
- A written record of the measurements collected
- An explanation of what the readings mean
- Identification of likely comfort or performance restrictions
- Photographs when relevant and available
- Prioritized recommendations
- Separation between urgent corrections and optional improvements
- A clear explanation of whether maintenance, repair, ductwork or additional testing is appropriate
- Credit of the $89 fee toward approved work
Formal load calculations, detailed duct design and advanced testing may be recommended separately when the initial findings show they are needed.
Origin of the Comfort Audit™
The Comfort Audit™ was developed by Too Cool Air to replace guesswork with measured, performance-based home diagnostics. While others may use the term, our process is defined by measurement, documentation and prioritized recommendations built around North Texas homes and climate conditions.
A typical seasonal tune-up focuses primarily on equipment maintenance. A Comfort Audit goes further by evaluating airflow, pressure, humidity and comfort-related system performance — and by writing down what was found so you can act on it in order of priority.
When the findings point above the ceiling rather than at the equipment, the Smart Hybrid Attic approach is one of the options we may discuss.
What Makes the Comfort Audit Different
The Comfort Audit™ is built around instruments, interpretation and documented findings rather than a visual checklist.
Diagnostic Equipment We Use
- • Digital manometers for static-pressure measurement
- • Calibrated hygrometers for humidity measurement
- • High-precision thermometers for ΔT measurement
- • Thermal imaging when the findings call for it
How We Interpret the Readings
- • Airflow and duct-performance evaluation methods
- • Psychrometric interpretation of temperature and humidity readings
- • Building-science factors specific to the DFW climate
- • Documented findings and prioritized recommendations

Common Questions
What does every Comfort Audit include?
Every Comfort Audit™ includes static-pressure testing, temperature-split (ΔT) measurement, relative-humidity measurement, a visual inspection of accessible system components, a discussion of the comfort problems you have reported, documented findings, and prioritized recommendations.
Which measurements are performed only when needed?
Direct airflow measurement, duct-performance evaluation, attic and insulation observations, thermal imaging, heat-gain observations, and additional electrical or refrigerant-performance checks are performed when the home or the complaint indicates them — not automatically on every visit.
How is a Comfort Audit different from HVAC maintenance?
A typical seasonal tune-up focuses primarily on equipment maintenance. A Comfort Audit goes further by evaluating airflow, pressure, humidity and comfort-related system performance, then documenting what was measured and what it means.
When is the $89 credited?
The $89 fee is credited toward approved work when you move forward with recommended repairs, upgrades, or installation.
How long does a Comfort Audit take?
Most audits take 1–2 hours. That time is used to take accurate measurements and explain the findings before we leave.
Will I receive written findings?
Yes. You receive a written record of the measurements we collected, an explanation of what they mean, and prioritized recommendations separated into urgent corrections and optional improvements.
Does the Comfort Audit include Manual J or Manual D calculations?
No. A formal Manual J load calculation or Manual D duct design is not part of the $89 Comfort Audit. Formal load calculations, detailed duct design and advanced testing may be recommended separately when the initial findings show they are needed.
Will you recommend replacement automatically?
No. We measure first and report what we found. In many homes the restriction is airflow, duct design or load — not the equipment. If replacement is worth considering, we show you the readings behind that recommendation.
