The coil itself is an essential component of an air conditioner system. It is typically located inside the air handler or furnace unit and is responsible for transferring heat from the indoor air to the refrigerant, allowing the system to cool the air in your home.A 3-ton air conditioner coil has a cooling capacity of 36,000 BTUs per hour.

It's important to note that when replacing or selecting an air conditioner coil, it's recommended to contact a qualified HVAC professional who can properly assess your specific needs and provide appropriate recommendations.
