Centrifugal fans are a key part of industrial and commercial HVAC operations, providing effective airflow for heating, ventilation, and cooling. Yet improper installation or wiring mistakes can cause substantial performance issues. One of the most basic yet overlooked issues is a centrifugal fan being wired in reverse.  Learning what the impact of this error is, […]

How High Static Pressure Affects Your HVAC System

Technician measuring HVAC static pressure using gauges with text overlay about how high static pressure affects HVAC systems.

Airflow is the performance key in any HVAC system. If air isn’t moving well through ducts, filters, and equipment, the system can’t provide comfort, and it uses more energy than it needs to. One of the largest performance robbers is high static pressure. Knowing what static pressure is, why it is important, and how to […]
