[quote=Anonymous]Op here. Thank you for these v helpful responses. There was a small pipe coming out of the old unit to the backyard and I don’t know if anything is coming out of it now (it doesn’t seem to be). The new basement return is larger than the old one and has a boot attached to it with tape around the joint that is falling off, could that be the leak I wonder? We adjusted the airflow settings on the heat pump to more closely mimic the old unit. We also did a home audit where they depressurized the whole house and saw some leakage from the ducts, and they are likely going to recommend replacing the flex duct in the attic. The home audit made the radon go from about 28 to 32. I would be grateful for any other HVAC suggestions, fine tuning or otherwise as to how we can reduce the radon in the house (in addition to the radon remediation. Thank you![/quote]
