You need to take the cover off and you should see some aluminum fins like whats on the outside unit the blower will either blow across them or pull air accross them. Clean them with a wire brush and soapy water if you dont have coil cleaner which can be purchased at hardware stores

The Outdoor unit will be easy 1st diconeect power at panel, or disconnect box near unit. Remove top of unit, be careful not to damage fan blades. Spray coils (fins) with a light degreaser let is soak for 5 mins. wash out coils from inside the unit out. Spray straight on so you push the dirt out the other side.

Re assemble and start up.

Indoor coil will be accessed by removing front cover and you may have another cover to expose the inside of the coil fins. That is where you need to clean. Spray degreaser on coils and rinse off. If its gunked up then use a wire brush 1st. Carefull not to bend the fins over.

Check the drain pan at bottom of the coil to be sure it's not full of stuff. Blow out if needed.

You should be clean and ready for the season

Brand New 2 weeks old 4 ton Trane compressor leaks a lot of water onto pad


If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.

The video gives you an example of the defrost cycle!

How a Central Air Conditioning System Works
amn_howac.jpg


Facts:
  • The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
  • Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
  • Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
  • The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
  • Central air conditioning can also be provided through a package unit or a heat pump.

Benefits:
  • Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
  • Cleaner air - As your central air conditioning system draws air out of various rooms in the house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to rooms.
  • Quieter operation - Because the compressor bearing unit is located outside the home, the indoor noise level from its operation is much lower than that of a free-standing air conditioning unit.

Blows very cold air during dehumidify mode.


se this fact: God bless you
air conditioning system cools but does not dehumidify the room. The most common cause of inadequate dehumidification by an air conditioning system is the installation of a cooling unit which has too much capacity, or is "over-sized" for the space it is being used to cool. What happens is simple:

If an air conditioning compressor unit is oversized (too many BTUH of cooling capacity) what happens is it cools the room so quickly that the system does not move enough total volume of air across the cooling coil to remove much moisture before the room temperature has dropped to the A/C cut-off point.

In other words, an air conditioner needs to run longer, and move more total volume of air through itself to drop room humidity than it does to just cool the air. So "bigger" cooling capacity or higher BTU capacity for an air conditioning system is not necessarily better, and it can actually be a problem.

How can I make the ac quieter inside the house?


If you have hard ducts, you can use some flex duct between the supply plenum and the hard ducts as a way to quiet the noise down.

My A/C blowing air, but it is not cool. It has started freezing up. We just replaced the air filters and since then it is freezing up. We even gently cleaned the a/c coils before replacing the filters. ...


Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.

Central Air, its a Trane, cools, however not very well. I think it needs a charge


First I would check your filters inside the furnace or air handler. Then if you have access I would check the a-coil. Sounds to me like you have a problem in the area of where the system transfers heat from the inside to the outside. Another thing that would'nt hurt would be to clean your condensing unit outside.
