Just finished commissioning a newly installed American Pride ductless heat pump system in Pittsburg. This involved a series of checks and adjustments to ensure optimal performance. I verified refrigerant charge using a manifold gauge set, measuring subcooling and superheat to confirm proper levels. I also tested airflow at each indoor unit, adjusting fan speeds as needed to achieve the manufacturer's specifications. Additionally, I checked the electrical connections and voltage, confirming proper operation and safety. Finally, I reviewed the thermostat settings with the homeowner, ensuring they understand how to operate the system efficiently. Proper commissioning of ductless heat pump systems in Pittsburg is essential for maximizing energy efficiency, comfort, and equipment longevity.
