How do I find my evaporator coil?

An air conditioner's evaporator coil, also called the evaporator core, is the part of the system where the refrigerant absorbs heat. That is, it's where the cold air comes from. The evaporator coil is located inside or near the air handler where the blower fan is.

Is the evaporator coil separate from the furnace?

The outdoor condenser and compressor, indoor fans, and evaporator coils cycle refrigerant and draw hot home air inside while releasing heat, then draw cooled air back through your vents. In other words, your central air conditioning system is independent of your furnace.

What happens if the evaporator coil is clogged?

An extremely dirty evaporator coil can cause your AC to breakdown completely. This happens when condensation forms on the dirt and then freezes during the AC's operation. The buildup of frost stops the heat transfer with the air in your home, which causes the air conditioner to stop cooling air at all.

Why is cooling misnomer?

The process of cooling is somewhat of a misnomer, because air is not cooled so much as the heat is removed. Refrigerant is sent to the evaporator coils inside the home to remove heat and humidity from the indoor air.

Do AC coils work in summer?

When summer comes around, you count on your air conditioner’s evaporator coils to remove warm air from your home, eliminate excess humidity and deliver that warm air outside.

The evaporator coils job is to help the refrigerant in the HVAC absorb heat from the surrounding air. In most cases, the evaporator coil will work with both your air conditioner and your furnace, depending on which system you are using at any given time.

How does an evaporator coil work?

When your evaporator coil is functioning as part of a cooling system, its job is to remove heat from the air inside your home. Your air conditioner will blow this warm air over the coil, after which the refrigerant will absorb the heat and lower the temperature of the air flowing across it. The indoor air is then recirculated throughout your system of ducts, providing a cooler temperature inside. However, when you run your furnace, the evaporator coil does not remove heat from the air blowing across it. Instead, the heated air must flow across the evaporator coil and through the same channels it uses to circulate treated air throughout your home.

How does an evaporator coil work?

The evaporator coil works when air flows over a series of thin metal fins that are cooled by the refrigerant within the copper tubing. Technically, the evaporator moves the heat from the air into the refrigerant and the cooled air is then blown into the home through the ductwork.

How does a compressor work?

The compressor keeps the process running by pulling the cold, low pressured refrigerant through the evaporator coils and transfering it to the condenser in a hot, high pressured condition.

What is the coil in a furnace?
