Comfort Audit
Raising the Standard for North Texas HVAC
At Too Cool Air, we believe that homeowners deserve answers, not guesses.
For too long, the HVAC industry in Dallas-Fort Worth has been plagued by "parts swappers"—technicians who guess at the problem and replace parts until the unit works, often at your expense.
We take a different approach.
The Diagnostic Difference
We use meaningful, calibrated diagnostics to measure exactly how your system is performing. We don't just check if it's "blowing cold"; we measure:
Psychrometrics
Airflow and humidity performance.
The Perfect Charge
Verifying refrigerant levels match manufacturer specifications exactly.
Electrical Systems & Components
Testing voltage, amperage, and component integrity under load.
Controls & System Logic
Evaluating control board sequences, safeties, and operational logic.
Airflow & Static Pressure
Measuring CFM delivery and duct system resistance.
NCI-Based System Performance
National Comfort Institute standards for total system performance testing.
Smart Controls & Automation
Thermostat programming, zoning logic, and automation diagnostics.
Indoor Air Quality (IAQ)
Filtration, UV, humidity, and particulate assessment.
Ventilation & Fresh Air Design
Evaluating fresh air intake, exhaust balance, and ventilation rates.
Combustion Analysis (Gas Furnaces & Safety)
Flue gas testing, CO levels, and heat exchanger integrity checks.
