I live in North FL. Area of high humidity. My a/c thermostats have a humidity setting but I cannot get % to drop below 49-50% downstairs and 55% upstairs even though I set to 40%. Suggestions or possible solutions.

RE: humidity

Half the installers I've dealt with over the years didn't wire the thermostat correctly. System information requested above will help.

RE: humidity

Please weigh in on humidifiers . What are pros and cons of Carrier HUMCCLBP2417. It is a "by-pass" 17 gpd humidifier. It is recommended with a 80,000btuh 2stage variable speed furnace 96%afue. Also, a TP-PRH-A, digital, programmable/ perfect heat/perfect humidity capable thermostat.
Are we going to get mold, rust or no humidity as I hear the horror stories? D oes this require a drain in the floor?
Is there a better way to go? Suggestions have been the Honeywell warm steam and the nordec. We were told that there would need to be 2 of those for a 2500+ house at a cost of $1500 per unit.

Can any of the experts on this forum suggest an HVAC expert to call in Tallahassee FL to evaluate my house building envelop to pinpoint the humidity problems I am experiencing. Thank you.
