answer ! - It is a dungeon

Answer 2 - it has been placed on part time work so it has lost its incentive to excel.

Answer 3 - There is no sound with out a receiver to hear it, there for YOU are weird for hearing it.

Honestly,  These are problems with out a solution since they are so vague and with out any context.  I don't even know why you asked them in this manner.

1.  Mold is growing because there is moisture on the walls.  Has nothing to do with HVAC system unless there is a leak on the condensate. 

2.  Frozen coil, dirty coil, faulty circuit board, incorrectly sized and designed duct delivery system.

3.  Noise?  Explain?

Here I'm talking about the clogged motor of the unit, blocked motor that makes different sound because of dead bugs, leaves and other debris when inserted in the motor. the sound also strange when the parts of the heating unit gets loosen.

dead bugs, leaves?  I have been doing HVAC service and installs for over 40 years and never ran across that issue at all.  I have seen plugged motors with dust but only noise from them was due to out of balance blower wheels causing vibration or bearings that have failed.

Mold on any wall is a concern.  Normally caused by leaks or excessive humidity within the structure and condensation on cold walls or ceilings.  if air is blowing on the wall, you will see build up called shadowing where dust collects on the cooler surfaces which are normally the framing member areas of the wall.

AAren,

On the mold issue.  Is this the inside of an exterior wall?  Hopefully not.  How high up on the wall is the register where the mold is growing on the wall?  Is there mold on the bottom 2 to 3 feet of the wall or only around the ducts . registers? 

Problem 1 - why mold growing near air ducts or on the walls?

The most common causes of mold growing on walls are high humidity, condensation and water leaks (which are often hidden inside the wall).

Condensation forms when water vapor in the air meets cold surfaces and cools to become liquid. Condensation is especially common on walls which form the perimeter of a house. These walls are often colder because of cool outdoor air on the other side.

Things like drying wet clothes inside or steam from hot water increases the humidity in the home. If humidity stays high in your home for a long time then you might see mold starting to grow on your walls. Usually the best way to decrease the humidity is to ventilate your home by opening windows and doors.

Leaking pipes near or inside of walls are a common cause of mold. If there's a leaking pipe inside a wall cavity then mold will usually be well and truly set in before it's discovered.

Answer 1. The most common causes of fungal growth on the walls are high humidity, condensation and water leakage (often hidden inside the wall). Condensation is formed when the water vapor in the air meets cold surfaces and cools to become liquid. Leakage of pipes near or inside the walls is a common cause of mold.

Answer 2. Here are the most common reasons your air conditioner isn’t working at full force

  • Due to dead thermostat.

  • Turn off accidentally

  • Got tripped due to circuit breaker

  • Blown fuse

  • Blown transformer

  • Due to dirty or clogged coils.

  • Dirty filters

  • Due to damaged HVAC components

Answer 3. If you hear gurgling sounds, these are often caused by low refrigerant charge. Heat pumps with dirty motor bearings can even make a noise, which you can describe as scary. This usually indicates an engine on its way to burning and the replacement is that can stop these weird sounds.
