DIFFERENCE BETWEEN EVAP AND DUCTED REVERSE CYCLE

A: Evaporative cooling works with water being dispersed over four pads, the fan brings in outside air through the water covered pads to give you the cooling effect. Evaporative cooling will drop the temp around 8 - 10 degrees.  They don't work very well on humid days. Refrigerated is able to bring the temperature down to a dedicated set point. Even if the temperature is 40 degrees outside and your set point is 22 degrees, it will be able to bring the t emperature to 22 degrees if sized correctly.

Can my gas heater have add on cooling

A: Yes and no. It depends on your heater, if your model of ducted heater fan capacity if rated high enough you can, however for cooling, the duct sizes are required to be upgraded as cold air is heavier and harder for the fan to move. Your gas heater should have an "XA" in the model number.
