Evaporator coils are essential to the proper functioning of your air conditioning unit, ensuring an optimal climate in your home or business. Just as the electrical coils that comprise heat strips warm the air that comes out of your heater, evaporator coils cool and condition the air that is released from your air conditioner. Your air conditioner works by drawing in surrounding air from your home. When the air passes over the evaporator coils, the heat is removed. The evaporator coils also work in conjunction with the condenser unit to condense the water in the air, thereby reducing the humidity. That way, the air that is released into your home or business is cool and dry, optimizing the climate during the dog days of summer.
There are several types of evaporator coils on the market today. Cased evaporator coils are the most common, with several different subtypes available, but you can also find uncased coils that can meet your unique needs.
Cased Evaporator Coils
The air conditioning units in most homes and businesses are equipped with cased evaporator coils. Cased evaporator coils are particularly popular because they are highly durable and because they are relatively easy to install. Within this category of evaporator coils, there are three common subtypes:
- A Coils. A Coils are named for the shape that they take within the case, which resembles a capital letter “A.” They are most commonly used in vertical air conditioners, in which the air flows either up or down as it pases through the coils. A Coils can accommodate enough refrigerant to operate at a relatively high efficiency.
- N Coils. Like A Coils, N Coils get their name from the shape of the coils within the case, which resembles a capital letter “N.” They can work for either vertical air conditioners or for horizontal air conditioners, in which the air flows in one side of the unit and out the other. It is important to note that N coils are growing in popularity because they are smaller than the other options and because they operate at a higher level of energy efficiency.
- Slab Coils. Slab coils are the least common type of coils on the market. They are usually used for horizontal air conditioning units.
Uncased Evaporator Coils
Uncased evaporator coils can work for either vertical or horizontal air conditioning units. They are ideal for systems that require customization because their is no outer casing. As a result, the shape of the coils can be easily maneuvered in an ideal position. However, it is important to note that after you purchase an uncased evaporator coil, you may need an expert technician to help you customize the shape to fit your unit.
