I have a 16 unit apartment complex and by far the biggest headace comes from the AC system. I have a large compressor that works with a rooftop tower/condensor. It pumps cold water to all the units. Each unit has a air handler ("furdown" style?) that takes the cold water through coiles, blows air over it, and makes the cold air.
At least that's how I think it works.
The system is from 1965 (uses R22 I believe?). I don't know what parts were replaced when (the tower on the roof might be newish?). The compressor might be original. All I know is while it makes Houston summers acceptable inside (high 70s) it doesn't work all that great anymore.
Anyway, I'm going to make a post asking some suggestions about what to buy to replace (I'd like to get individual units for everyone) but I'd like to understand what type of split system I need. From what I understand I have a 'furdown' system for the insides (the air handler sits in a space above the bathrooms) so if I get a split system for all the units I'd have to get a 'furdown' system for the inside.
So my question: How the heck is the inside unit said/spelled. When I google or wikipedia it, I get nothing confirming. And forums that come up seem to spell it differently. Is it furrdown? Furdown? etc?
Any help for this newguy apartment owner would be great (and if you want to suggest what I should get in the way of new individual units that would be awesome, or if you think I should replace the main condenser/compressor instead, I'd welcome that discussion as well).
