    Florida Humidity Control. Good enough for some, but typical FL Weather.
    I like the steady less <50%RH that a dehumidifier provides.

    Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
    Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
    Use +Merv 10 air filter. -Don't forget the "Golden Rule"

    This is a complex expensive system but this type of system needs significant cooling load to remove the moisture from the occupants and adequate fresh air ventilation. A small ventilating dehumidifier would make the system complete.
    Keep us posted.

    Humidity is quite pleasant this time of year when there's no cooling load. Plenty of fresh air, too, as I open the atrium sliders to enjoy the outdoors. No need for mechanical add-ons!

    More info than you want. I am attaching a pdf of the outdoor dew point affecting the indoor dew point. When the dew point inside below the outside dew point, a/c or the whole house dehumidifier are removing moisture. When the out dew point is below the inside dew point, the fresh air moving through the home is contolling the indoor dew point. The graph is this week which is typical of winter weather in FL.
    This gets -+ 80 cfm of fresh air in moderate winds.
    FL homes need a dehumidifier if they want dependable <50%RH during mixed weather.

    The touchscreen controller for the Greenspeed displays humidity, but I picked up the below item at Home Depot for about half what they sell for on Amazon. It also tracks high/low temp/humidity over time.

    Wow. That is really nice. It will be very exciting to see if your bills go down and comfort goes up to or beyond expected levels.

    I'm keeping my fingers crossed.

    While this process is fresh in your mind, any comments or observations about the decision making process, suggestions/advice to homeowners from the ho perspective?
    Which makes more sense to you?
    CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
    ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%

    DO THE NUMBERS! Step on a HOMESCALE.
    What is comfort? Well, it AIN'T just TEMPERATURE!

    Energy Obese? An audit is the next step - go to BPI.org, or RESNET, and find an auditor near you.

    Looks like they did a great job. I'm glad you finally found a good contractor and got a good unit. I'm glad we all could help you through your decision and best of luck in the future.

    I expect that I will be replacing my central a/c system this year.

    It appears that you were satisfied with your contractor.

    In part because I am interested in installing a similar equipment, I would like to know which contractor you used to install your Carrier system.

    Thanks,
