My AC blows cold air, so I assume my compressor outside works OK. Please correct if that's an incorrect assumption.
The problem is, there is very little cold airflow that comes out of the floor ducts... To the point that closing all the windows and running AC makes a negligible difference in room temperatures, at least as much as the wife desires it to alter.... I.e. if 85 inside and we set it to 70, the 70°F is never reached.
I have the setup where compressor is outside, and fan/evaporator coils are inside as part of the furnace unit.
Can any components be swapped internally to alleviate this low air condition, or is a new system the only option? My dad said the motor and fan can be upgraded, but he knows refrigeration better than AC hence why I'm here asking.
Lastly, my house was built in the 70s, could this also be a problem with an inefficient HVAC duct design more than the poor and old AC system?
PS, filter is brand new so that isnt the issue
