I recently retired from HVAC work. I had a prior customer of mine buy a house that has an HV system in it.
His compressor siezed and it is R-22. He had a local company give him an estmate for a new system.
Their proposal lists a Coleman 3 ton air handler. He called and they said they would use the existing ductwork. He asked me what I thought and I told him to run away.
Has anyone ever put a standard air handler on an HV system? If so has the airflow been adequate to cool the space?
