Just installed an Infinity system. My old AC system was undersized by about 1/2-3/4 ton and could never really cool house properly. Old AC was set at 74 degrees. With new system I thought i would play around with temp as dehumidify with Infinity was much better than old. One thing I noticed...Temp set at 74 the humidity level on readout is always in the mid to high 30 percent humidy. I thought i would raise thermo temp up to 75 to see if house still felt cool. I raised to 75 on Saturday aftenoon and checked humidity level on Sunday afternoon. It was in mid to high 40% range and wife said it felt much more humid in the house. Is this normal for 1 degree increase to cause 10 percent increase in humidity levels? Outside conditions were about the same during both periods.
