## Educational Resources

### Forced Air vs. Central Air Systems
While similar, the two differ in duct layout and components. Forced air refers to the delivery method (ducts and a blower), while central air specifically refers to a centralized cooling mechanism connected to those ducts.

### Choosing the Right Commercial Heating Design
Commercial designs consider load requirements, ventilation rates, and zoning requirements. Variable Refrigerant Flow (VRF) systems and packaged rooftop units (RTUs) are popular options.

### Common Heat Pump Repairs
Heat pumps provide both heating and cooling. Common repairs involve reversing valves, defrost board failures, and refrigerant leaks.
