No condensate from HVAC drain
I am a first time homeowner of a 45 year old ranch with a 22 year old HVAC, and the condensate line drain for the AC is dry, although the 22 year old system is working. The outside condenser is clean, but does seem to run a lot, inside filter is replaced at regular frequency. I do have a dehumidifier running in the basement, collecting over 1.5 gallons/day, but the independent humidistat in the basement averages about 70%. At first I thought it was a clogged line, but it is not. How do I without knowledge of HVAC systems or local contractors/service personnel depend on their assessment, as the system is functional--but AC without condensate??? Doesn't make sense to me. Any ideas, how does one approach the problem if there is one? Central Illinois humidity without condensate...? Thanks. John.
Required Trouble Shooting Data
My advice: get a low cost humidity gage at a local hardware store & see what the percentage-RH is in your home, I can cross-reference that to the wet bulb depression.

If you want meaningful help, provide us with most, if not all, of the above EASY TO TAKE data.
Then perhaps, we can ballpark an opinion on what the unit is doing.:)
