The mood of the crowd was upbeat. And why not? Most wholesalers agreed that times have been good, and remain so...at least for now. The Big Easy was the site for the NorthAmerican Heating, Refrigeration and Airconditioning Wholesalers (NHRAW) annual convention in December. Snips was there to observe.
NEW ORLEANS - Just when you thought all the old questions about refrigerants had been cleared up¿ Equipment manufacturers and refrigerant suppliers continue to get phone calls from hvac service contractors asking if it is OK to replace the R-22 in a system with R-410A.
No, it is not. For several reasons, R-410A is not a drop-in replacement for R-22, although R-410A systems are rapidly displacing R-22 systems as the air conditioning technology of choice. But the fact that they are getting these calls means many contractors are still confused on this subject, and probably also means that many are making the direct, drop-in replacements without bothering to find out more.
