In order to maintain good air quality you need return air ducts for the furnace. The return air intakes also help balance the temperature differential in the room, return air also helps maintain a safe temperature for the heat-exchangers with out the return air helping reduce the temperature around the heat-exchangers thermal overloads would trip out and shut down the furnace and the danger of rupturing the heat exchanger which would allow combustion exhaust and carbon monoxide entering in to and mixing with the supply air making a deadly situation for the occupant's.
Supply and return grille locations are figured by the HVAC engineer or the contractor.
The air is probably too cold causing condensation at the vents. try increasing the air flow which will warm it a few degrees.
Compressor not operating.
Well first of all.. You want heat in your house when it's cold, RIGHT? So you turn on the heater with the knob.. and the heat comes out of the vents. No vents = explosion. And basically.. no vents as I said.. explosion, because the gas has nowhere to go so the pressure will build up and BOOM.. flames.
I would think both. Cold air from the room goes in the bottom and warmer air comes out the top.
Cold air return vents are the ones on the wall
The heater may not be on - but the fan still blows air through the vents when they're open !
No sunlight reaches that depths, although if you go far enough down there're hydrothermal vents which in return heat things up.
to keep the plant cold

If it still blows cold when it is at running temp, check the engine thermostat, its probably stuck in the open position.
the middle vents only supply air from the ac unit using a separate in dash fan. the floor and defrost vents come only from the heater
The a/c - heater controller is out...........
no
* Return air is blocked * Filter is loaded * The fan (squirrel cage style) is clogged with dust * A duct has become crushed, blocked or disconnected. * The fan motor is burned out.
You can hire someone to unblock the vents or get space heaters.
most likely it's a bad thermostat, or your vents not working properly.
