Installed a new heat pump 3-4 years ago after nordine unit had trouble. Only changed the outside portion of system not inside fan. System falls behind - one end of house especially, but whole house when temps get to about 90 outside will not get but 12-15 degrees cooler than outside even when unit runs all the time. Do we need a new fan or is it did to replacing with a high efficiency heat pump (as advised for energy savings)?
