I recently had the following Rheem ROCB furnance installed.
It's paired with a Rheem 5 ton condenser for cooling. However, I feel the air flow is set way too high. The house cools down very quickly (typical cooling cycle only lasts 7 minutes) and the strength of the air coming out of the vents is very strong.
I was reading the manual of the furnace and there are dip switches to control the rate of air flow. Here is the manual page that discusses it.
Currently, the furnace is set to 5 tons. My question is, is it truly as simple as adjusting the dip switches (per the manual settings) to lower the airflow CFM? Would doing this introduce the risk of any other adverse effects to the rest of the system?
