Get ready to add electric heat to your package unit the right way. In this video, we walk through installing heat strips on GrandAire units. You will see how to choose the correct kW kit, verify voltage and circuit ampacity, mount the heater, connect high-voltage and control wiring, set dip switches or jumpers, adjust airflow for the added heat load, update thermostat settings for auxiliary heat, and finish with a safe system test. We also cover common mistakes and simple checks that prevent trips and burnt elements. Always cut power at the disconnect and follow local code.
