Green Bay – September 22, 2026 -- Uneven room temperatures rarely mean a heating or cooling system has failed — the real culprit is often an airflow imbalance that a process called air balancing can fix, according to Green Bay HVAC professional Brian Sinkler of Sinkler Heating and Cooling, Inc.

Technicians test airflow at every vent to find the problem

Air balancing starts with measuring output from each vent to identify rooms getting too much or too little air. These readings pinpoint issues that adjusting a thermostat alone cannot solve.
