HVAC linesets connect a HVAC condenser to an evaporator. In mini-split systems, the lineset connects indoor & outdoor units together. In this case, the outdoor unit condenser supplies the indoor evaporator with refrigerant. The lines slightly differ in size, where the smaller tube, called the discharge line, will carry dense liquid refrigerant into the evaporator […]

However, some protective options currently available such as jacketing, are still making installers work extra hard to find the right lineset configuration and prevent damages. With that in mind, Inaba Denko Japan developed the Slimduct PD. A […]

The Variable Refrigerant Flow (VRF system) was created in Japan in the early 80s. VRF is an HVAC technology that allows for varying degrees of cooling in only certain areas. Even though VRF systems are similar to multi-split systems, they do have one key difference. For instance, multi-split systems turn on and off completely when […]

Vertical lineset installation comes with some challenges. Every professional knows the importance of keeping things aligned.
