Did some searching and have not been able to find diddly on this furnace. Its a older Rudd HR-80FD and it has always seemed to be underpowered as far as the blower is concerned. What can I look for to see if it has a variable speed blower that I can possibly increase? In the summer the temp from the central air seems quite cold, but the airflow is pathetic. Any input would be appreciated. If I could bump the blower speed up it would save me a service call.
Thanks!
Charlie.
