What do you do when you cannot get proper airflow for AC installations. In my location we have tight building construction with low cooling loads. If you notice furnace manufactures fan curves don't work well with 1 1/2 ton or 2 ton systems. Most of furnaces start around 900 cfm on low.
What do you guys do with a siyuation like this? Or a belt drive system that is set for the proper air flow for heating?
