Lennox variable speed furnace/ac unit. Compressor is outside home. Evaporator is inside in the basement right above blower fan.
Issue is: on normal use there is no condensate.
I believe AC is cooling home fine. I do not know how efficient though. I set my thermostat to 77 and when AC is on, the temp coming out from coil reads about 55. Return air reads about 74.
I am running factory set option - when thermostat calls, blower runs at 82% speed for 7.5 minutes and after that blower goes to 100% if required until thermostat demand is satisfied. What I observed is most of the time mine turns off after 7.5 minutes. This is the case where there is no condensation. Drain pipe runs to floor drain in basement close to the unit. Once in a while it runs for more than 7.5 minutes and so it goes to 100%. This is the case where I see condensate dripping. This tells me that drain pipe is not clogged.
Is this normal for NOT to have condensate during normal run of the AC? My basement humidity is about 52 (I have a portable dehumidifier in basement). My first floor humidity level from my IAQ stat reads between 55 to 58.
Thanks for reading this long post.
