Professional HVAC Airflow Balancing and Testing
Hot upstairs rooms, weak registers and an AC that never seems satisfied usually share one cause: the air is not being distributed the way the system was designed for. Too Cool Air's Airflo Audit measures how much air each room actually receives — using flow-hood readings, static pressure and duct performance data — then corrects what the measurements identify.
Too Cool Air is based in Grapevine at 410 E Northwest Hwy #10 and provides airflow testing and balancing throughout the DFW Mid-Cities. Appointments are scheduled according to availability — call (214) 437-7886 or book online below.
Signs Your System Needs Airflow Balancing
These comfort problems usually trace back to distribution, not equipment:
- Some rooms run five to ten degrees warmer or colder than others
- Upstairs never cools even though the AC runs constantly
- Some registers blow strongly while others barely push air
- Humidity stays high in certain rooms
- Vents whistle or ducts pop as the system runs
- Energy bills are high but the house is still uncomfortable
What the Airflo Audit Measures
Balancing starts with instruments, not opinions:
- Total system airflow at the air handler against the 350–400 CFM-per-ton design range
- Room-by-room supply airflow measured at each register with a flow hood
- Static pressure at the supply and return plenums
- Duct leakage and restriction points, including kinked or crushed flex duct
- Return-air capacity and filter pressure drop
How Balancing Works
- 1Measure total airflow and static pressure at the air handler.
- 2Measure actual CFM at every supply register with a flow hood.
- 3Compare measured airflow to each room's design requirement.
- 4Identify restrictions, leaks and undersized runs the readings expose.
- 5Adjust branch dampers to redistribute airflow where the data says to.
- 6Re-measure every register and static pressure to verify the improvement.
- 7Document before-and-after readings for your records.
Why Too Cool Air Balances Ducts Differently
Most comfort complaints are treated with equipment sales. Too Cool Air treats them with measurements first: if balancing, a duct correction or a return-air upgrade solves the problem, that costs a fraction of a new system — and we will say so. Every adjustment is bracketed by before-and-after readings, so the result is documented rather than promised.
Owner Sergio Villarreal (Texas license TACLB50985E) has focused on airflow and static pressure throughout more than 28 years in North Texas HVAC.
Why Balancing Beats Guesswork: A Real Example
A homeowner in Trophy Club was quoted $12,000 for a new AC system because the upstairs bedrooms were unbearable — the competing contractor blamed an undersized system. Our testing showed the real problem: the 3-ton system was delivering about 850 CFM where roughly 1,200 CFM was required. After balancing the airflow and correcting a kinked duct, every room reached its target temperature.
That example comes from our complete HVAC airflow balancing guide, which documents the measurements, tables and methods behind the process.
