Diagnostic call on a Lennox air conditioner. Upon arrival customer stated that the system is cooling and satisfying temperature in home, but it is leaking downstairs by furnace. Found condensation drain line is clogged and holding water I took the drain apart and blew out with nitrogen, also put some bleach down drain to clean it out. I then put drain line back together and cycled system in heat and all was ok. System went through heat cycle with no issues, then switched to cool and kicked on with no issues. System operational and cooling at departure.
