Do I Need a New Central AC Unit?
I have a central air conditioning unit that is 30+ years old. It will cool the downstairs of my home adequately however in the past few years it has a very difficult time cooling the upstairs. I have had a "handy man" with HVAC experience come and look at the central ac unit.
He stated that my venting from the unit is the problem (although it doesn't seem to be a problem heating the upstairs) and recommended against a new AC unit. He recommended trying to reroute the two vents to the upstairs.
I think the age of the central ac unit is primarily the problem. Any advice?
