Air Conditioners Gulfport, MS
Central air conditioners are appliances that circulate cooled air through ducts and openings in walls, ceilings, or floors in order to keep a house cool and comfortable. The air that enters the living space gradually warms, at which point it is taken in through return ducts and sent back to the air conditioner. A broken air conditioner typically needs special maintenance performed by a licensed air conditioning contractor or HVAC contractor.
Basic Types of Central Air Conditioners
There are 3 basic types of air conditioners:
Split-System Central Air Conditioner
Split-system central air conditioners are the most common type of AC used in the U.S. Houses who use this kind of system will have an evaporator coil somewhere in the house, such as in a closet, tucked away. It is responsible for removing heat and moisture from the air. Outside of the house will be the rest of the system—the condenser coil (releases heat) and the compressor (responsible for pumping refrigerant between the condenser and evaporator coils)—encased in a metal cabinet. A split-system central AC cools the house by circulating cooled air through ducts with the help of a blower. Split-systems are the most economical choice in houses that also have a central furnace, as the two appliances can share the ductwork.
Packaged Central Air Conditioner
A packaged central air conditioner stores the evaporator coil, condenser coil, and compressor into one cabinet, which is usually located on either the roof or next to the house on a concrete slab. Air flows into and out of the house by way of ducts that go through either the exterior wall or roof (depending on air conditioning placement) and connect to the unit. These types of air conditioners often have electric heating coils or a natural gas furnace that eliminates the need for a separate heating appliance. Packaged central air conditioners are often used in small commercial buildings.
Ductless Mini Split-System Air Conditioners
Ductless mini split-system air conditioners are a special type of split-system unit. They are usually easier to install than their counterparts, but may cost more, especially if they are used to cool an entire house. They are often used in housing meant for more than one family or are installed in houses that have a heating system that does not use ducts. Like regular split-systems, the ductless variety consists of both indoors and outdoors components. Air is transported through tubing that connects the outside unit to the indoor unit, which is mounted high on a wall. There may be multiple indoor units, as each unit only heats one room. Ductless mini-split air conditioners are great for homeowners who want to control the temperature of certain rooms independently from the others, as well as those who do not fancy the idea of ripping through walls to install ductwork.
SEER, or Seasonal Energy Efficiency Ratio, is a measure of the amount of energy used to cool a home. This number is calculated by dividing one summer’s worth of cooling output by the total amount of energy consumed during that same period. Central AC units typically have a SEER of 13 to 28, with people in hot and humid climates advised to choose a unit that has a SEER of at least 15.
EER, or Energy Efficiency Ratio, is a measure of a unit’s efficiency at any given moment. It is calculated by dividing the cooling capacity of the air conditioner by its energy consumption, as measured in watts.
