HVAC ContractingNewsVentilation For the last few years, much of the focus on cold climate heat pump (CCHP) technology has centered on air-source ducted systems, which are designed to deliver efficient, comfortable heating, even in regions that experience extreme winter temperatures. However, an increasing number of ductless heat pump solutions are proving they can stand up to the cold just as effectively.

Field-mixing refrigerants is also a bad idea, as refrigerant blends such as R-454B are engineered to exact specifications, and altering their composition in the field compromises both safety and performance. And switching back to R-410A is neither backward-compatible nor recommended by OEMs, as system components and charge requirements are designed specifically for the properties of R-454B.
