when deciding on what size water to air heat exchanger you need measure your plenum above the air conditioning coil then buy the next size smaller of the measurement. example if your plenum measures 21x21 then buy the 20x20 water to air heat exchanger. you want to be able to slip the water to air heat exchanger inside you duct work. then you want to install a 90 deg angle piece of metal that you will screw to the inside of your duct. this shelf should be installed on both the left and the right inside of your duct. you also want to make this shelf on the back of the duct as well. when building this shelf it will hold your water to air heat exchanger in place and last you a lifetime. speaking of lifetime your water to air heat exchanger has a lifetime warranty as well and fell free to call day or night with questions
