I was talking about dry contacts with one of my techs, and he looked at me like I had three heads—and one of them was on fire. So, I figured it would be good to cover the difference between wet and dry contacts in a tech tip. Basically, “dry” contacts are switches with no shared […]

Refrigerant migration is a natural process that occurs during the off-cycle. The refrigerants have an affinity for oil and seek out the lowest-pressure areas, so it only makes sense that some refrigerant would be drawn to the compressor crankcase and may condense there. When the refrigerants condense, they saturate the oil. As a result, refrigerant […]

The way we use and think of refrigerants is evolving quite rapidly. As we shift towards phasing out ozone-depleting refrigerants and considering alternatives, the future of refrigerants may seem a little uncertain to us. However, one thing is certain. Many HVAC units will continue to rely on the common HCFC, HFC, and HFO refrigerants we […]
