This course will overview ducted mini-splits. Indeed the term mini-splits doesn't necessarily mean the indoor unit is ductless. It will cover the different types of ducted mini-splits, low and medium/high static pressure types, as this will greatly impact how much duct a ducted mini-split can handle. It will give examples of situations in which a ducted mini-splits is a good option. Lastly the course will touch on the cost of a ducted mini-split compare with a multi-position air handler, and ductless indoor units. We will also cover the new cold climate air source heat pump decisions tool from PNNL Continuing Education Units (CEUS) submitted 1 hour in* Green Business Certification Inc.

He works on research projects related to heat pumps, heat pump water heaters, high-performance windows, and quality installation documentation. Lessons Learned Understand that proper installation and maintenance of ducted mini-splits is crucial for ensuring indoor air quality and overall health. Analyze the impact of different types of ducted mini-splits on air pressure to guarantee safe and efficient operation within specified duct capacities. Introduce the use of ducted mini-splits as a viable option in various heating and cooling scenarios to ensure the welfare of building occupants. Articulate the cost-effectiveness of ducted mini-splits compared to other HVAC systems, considering both initial investment and long-term maintenance for the safety of the users.
