i had a Rheem prestige series, 15 Seer, just installed. In the heat cycle, the unit's air flow makes considerable noise. The technical lowered the CFM in the heat cycle to 720 CFM. In the cooling cycle, it is now 600 CFM and it is good. How low can I safely adjust the heat cycle CFM?
Type of HVAC: Air Conditioner
Lowered heat cycle CFM to 720 an air conditioning to 600 CFM.
You cannot lower it any lower than 720 cfm
If you lower it lower than 720, the airhandler will overheat.
Thank you. Any ideas to lower the air noise in the heat cycle
Are the ducts insulated well?
They appear to be
I have no other ideas other than adding more insulation to the ducts.
Thank you for using JA!!

Hello,you may be adjust the fan speed. Is the air handler equipped with electric back up heat? Or is there a gas Furnace? You can always install more supply registers or return alsoIf you have indoor model number I can be specific.
