Our Refrigerant Future Continues to Change

This blog post will close out the series on Quality Installation. But I didn’t want to move on without taking a high level look at the future of refrigerant.  One thing is certain in this segment of our industry.  And that is change is inevitable. The focus on...

Ensuring Proper Refrigerant Charge

Continuing the discussion of the quality installation (QI) process, the next step is ensuring that the cooling equipment is properly charged. Original Equipment Manufactures (OEM) provide us with detailed guidance on charging procedures and very specific superheat and...

Evacuation of the Refrigerant System

In the last post, we looked at the issue of air in the refrigerant system and how important it is to get the air and moisture out during the installation or service process.  Evacuation of the refrigerant circuit has always been a bit of a challenge for several...

More on Catalysts

In the last post we looked at the challenges associated with the formation of copper oxides within the refrigerant circuit when dry nitrogen is not used during the brazing process. In today’s post, the focus is on “air” within the refrigerant system. Air is a common...

Quality Installation – Refrigerant Piping

Today’s discussion: Refrigerant piping. The indoor coil and outdoor unit are both connected via the refrigerant tubing line set. Routinely, line sets require they be cut to fit, which means care must be taken during the cutting process to prevent copper shavings from...

QI – How important is the load calculation?

Of all the processes that our industry seems to struggle with, completing a legitimate load calculation seems to be one of the most contentious.   The load calculation is the cornerstone of the entire design, install and service process.  If done properly it can...
