I attended a conference hosted by the Building Performance Association and presented on air-to-water heat pump systems. Many professionals were interested in heat pumps, especially ductless air-to-air systems. One person mentioned the difficulty of finding qualified installers for air-to-water heat pumps and noted the higher cost compared to ductless air-to-air systems.

RectorSeal’s Outset Seal, an adjustable lineset protection system for ducted and ductless HVAC installations, is designed to protect indoor areas by blocking air leakage, moisture penetration and rodent intrusion and hiding unsightly wall penetrations where HVAC linesets enter or exit structures.
