Last month we discussed the importance of using the proper filter-drier in an air conditioning system that uses R-410A. This month we will take a look at other service practices that can affect the operation of an air conditioning system that uses R-410A.
In order to install and service the increasing number of 410A unitary air conditioners and heat pumps continuing to enter the market, large numbers of contractors have sought training. Some of it is specific to 410A systems, but much of it is just good service practice that should be applied to any unitary system.
