Types of Air Conditioners

Room air conditioners cool rooms rather than the entire home. If they provide cooling only where they’re needed, room air conditioners are less expensive to operate than central units, even though their efficiency is generally lower than that of central air conditioners.

Smaller room air conditioners (i.e., those drawing less than 7.5 amps of electricity) can be plugged into any 15- or 20-amp, 115-volt household circuit that is not shared with any other major appliances. Larger room air conditioners (i.e., those drawing more than 7.5 amps) need their own dedicated 115-volt circuit. The largest models require a dedicated 230-volt circuit.

Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers (i.e., openings in the walls, floors, or ceilings covered by grills) carry cooled air from the air conditioner to the home. This cooled air becomes warmer as it circulates through the home; then it flows back to the central air conditioner through return ducts and registers.

 

 

The packaged central air conditioner is usually located outdoors and consists of one cabinet that contains the evaporator, condenser, and compressor. The cabinet is usually placed on a roof or on a concrete slab next to the house’s foundation. The packaged air conditioner is connected to the indoor air supply and return ducts through the home’s exterior wall or roof.

 

Since these air conditioners often include electric heating coils or a natural gas furnace, this combination of air conditioner and central heater eliminates the need for a separate furnace indoors. This type of air conditioner is used to cool and heat homes as well as small commercial buildings

When someone refers to a split air conditioner, they are referring to the way in which the unit is set up.  A split air conditioner is composed of two separate units, a condensing unit and an evaporative coil (known as a “condenser,” and a “coil” respectively in short-hand or slang).  It is from these two separate units that a split air conditioner gets its name.  These units are joined by a set of copper tubing known as a “line-set,” which transfers refrigerant from one unit to another.  Here are some examples of split AC units: Carrier Split Air Conditioners.

 

 

Once you know what types of AC units are available, it’s time to decide which one is best for your home. This depends on your budget, square footage, SEER ratings, warranties, and features.

 

They a superb dealer network so components are normally close while something goes wrong and you want a repair. Amana also, at maximum of the dealers I have dealt with, have schooling programs for his or her technicians to hone their abilities on HVAC structures and the Amana line of HVAC products. I have also heard brilliant things approximately their technical support people that will truely go to the technician within the subject to clear up technical issues as necessary.
