I have a Lennox air handler. What should I do to troubleshoot it?

Working with any type of refrigerants, ex: R22 and R410 requires a liscense. If you need Freon have a liscensed technician do this. Otherwise, Check that your coils are clean, check that your filter is clean, check that your condensate line is free of debris, check for ice on coils.

At first when you come to know that the air handler will give you some trouble you may contact the company where you purchased they will guide you better.
