    Thumbs up

    I ended up purchasing the 21 SEER 4 ton IQ Drive. It was installed this weekend. So far it's working great. It got up to 91 deg and 90% humidity out today and the unit had no problem keeping up. At the heat of the day it ramped up to about 75% of nominal capacity for a short period (based on the system information I read off the thermostat). It seems to run a lot at its lowest setting (25% of capacity).

    The unit is very, very quite, when it's running at it's lowest setting, I have to open the closet door to hear the air handler. The outside unit can not be heard from inside the house. Even outside the house, you almost have to walk up next to it to know if it's on.

    I am anxious to see how much my electric bill will drop.

    Thanks to everyone who gave me advice on this. I really appreciate it.

    How many times must one fix something before it is fixed?

    Just an update on my elec bill. My July and Aug bills were both 40% lower ($130/mo) than my June bill (with higher avg temperatures). Not too bad. I would definetly recommend the IQ Drive units.

    One thing you will really enjoy about your new IQ drive system is the humidity control, especially when you get into more mild, but humid, Florida weather.
    The dehumidification mode, that is integral to the system, beats all others.

    Did you have anything done with the duct system, duct blaster test of the ducts, or blower door test of the whole house, or just replace the equipment?
    If more government is the answer, then it's a really stupid question.

    I think your right Mark. The dehumidification mode is nice. I did have a blower door test of the house. They found some monor leaks, which I repaired.

    Thanks to everyone on the board that helped me with my decision. It is very much appriciated.

    Now with equipment like what you have the key is to now find a comfort setting on your stat and leave it there, and do not set it back 10 degree's like some poeple do and make your AC work harder than it has to. You'll find by setting it and leaving it at that setting your house will be very comfortable, During the cooling season do not have the fan running on low unless you find it doesn't raise the RH in the home but if it does leave the stat on auto and as I mentioned set it and forget about it. But do remember to change your filter regularly
