A "coil" is a length of copper or aluminum tubing that has been wrapped or folded into a compact package. A refrigerant gas, such as Freon or ammonia, is pumped through the coil by the compressor. Air is blown past the turns of a coil to absorb or reject heat. There are two coils in an air conditioning unit, or any refrigeration unit, for that matter -- an evaporator coil inside (gets cold) and a condenser coil outside (gets hot).
Yes it does.
Inside the unit under the evaporator coil. The condensate drain line is attached to it.
There should be only one blower to move the air. The unit will have a coil for cooling and a heat exchanger.
how to check out the relay in a central air conditioning unit
in air handling unit
Omg not a leaking central air unit those are the worst
In a word, no. This area has to remain relatively free of obstruction so air can flow around your condenser coil. Restricting the air flow across the condensor unit will increase your unit pressure and not operate correctly.
fan coil unit
the aircondition fan is located in the outside unit of a central AC unit. It sucks outside cool air thru the fins and tubing that contains heat from air collected from inside the house thru the A-coil that's sitting on top of your heating unit. The inside fan in the heating unit blows air thru the cold air moving thru the fins and tubing in your A-coil and blows that air into your house. If you hold your hand above the outside unit while the fan is running you can feel the hot air that's coming from inside, this is how the heat is removed.
depending on the size of the unit i took 2.5 ton off and made$60.00 off it and the copper lines that connect it $27.00 so if you have an old unit it is worth taking off .
The coil are responsible for transferring of cool air trough the unit
well if your talking about a dx coil in refrigerators and air conditioners there are special chemical cleaners availabe.
