    Haven't actually done it yet, and it has not even been discussed. All our refrigerant we use is billable, so why risk it.

    Hey Allen, The app I got and like is called "Psychrometric Plus". I may have paid a couple of bucks for it, but it was the one I like best. You can input any two quantities and the rest are...

    Now that I think about it, most have outside air units (Desert Aire for one). Everything control wise we do is moving toward "demand ventilation". The CO2 in the building is monitored, and the system...

    Sounds a heck of a lot more ecomomical than reheat!!!! I wonder why I haven't seen it in commercial. Could be a lot of the AHU's I've worked on are older technology? Maybe before dehumidifiers became...

    Thanks for the input teddy bear. Always learning. Was thinking commercial when I made the statement. I have never seen a dehumidifier in a commercial system, only reheat. I live in the south...

    Dual fuel is the way to go with heat pumps. The most expensive heat is pure resistive, second is gas heating, and the cheapest is movement of heat i.e. heat pump. In my opinion the gas option is best...

    The fact that the units are grossly overcharged/undercharged tells me the previous techs had no idea what they were doing. With the modulating compressors and fans, the old rules go out the window....

    If it has been there a while, it probably has a dual fuel kit mounted in the furnace with an external thermostat in the condensing unit. Its my understanding that this old technology. I agree with...

    I agree with pacnw. I now use a 50va transformer with a resettable fuse. For a few bucks more I get a little safety margin and a resettable secondary fuse. No more manually tieing fuse holders to...

    I also like the total heat formula. Of course the key, as usual, is the determination of the airflow. I have also found an app for my iphone which has the psychrometric chart in computer format. All...
