Humidity vrs Central air Cooling?

Question:What would be the ideal humidity inside a Southern California home during the summer and cooling with central air conditioning.

Answers:
Actually if you go below 50% RH you will feel quite dry, in fact too dry. The other consequence is that the static electricity in the home builds up as well at lower humidity levels, this can be a problem if you have carpet in your rooms :-)
The advisable level is somewhere between 55 and 65%RH if you have the ability to control it, all the better.
A/C in dry climates tend to over dehumidify the air as the moisture in the air is condensed on the indoor evaporator coil and drained away.causing dry eyes etc and A/C in high humidity zones tend to add to the cooling capacity making you feel less comfortable.
Some people in dry climates have been known to put containers or bowls of water in their home to keep the dryness at a reasonable level.
Hope this helps.
