After absorbing heat from the warm air, ...
What causes a refrigerant to leak out?
The evaporator and condenser coils both play important roles in the cooling cycle. A leak in either set of coils can cause the refrigerant to leak out.
What happens when refrigerant levels are low?
When the refrigerant levels are low, the evaporator coil does not work as efficiently. It is less effective at cooling the air that passes over the coils. There are two sets of coils in a typical air conditioner unit, the evaporator and condenser coils. Both coils are essential to the operation of your AC system.
Why are coils important?
Both coils are essential to the operation of your AC system. They also both hold the refrigerant at different stages of the cooling cycle. A leak in either coil can result in low refrigerant levels.

What happens if your AC coil is bent?
If you’ve got a damaged air conditioner coil, a number of things can happen. If it’s early stages and the coil is simply bent or broken, then a repair might be the most cost- and time-effective route to take. However, it’s fairly common for a coil to be damaged not due to a bump or bend, but due to corrosion. Over time, the coil’s inner and/or outlet lining may break down due to corrosion – and, when this happens, it’s also common for a refrigerant leak to follow. If your coil is at this point and your unit is leaking, a coil replacement is likely to cost less than a repair (and much more likely not to give you issues again anytime soon). In any case, you won’t know for sure until your HVAC technician gets the chance to have a closer look at what’s going on.

What is the AC unit in a home?
Central home air conditioner service systems consist of two major components: a condensing unit that sits outside your house, and the evaporator coil (often referred to as an A-coil) that sits in the plenum of your furnace or air handler. The refrigerant in the A-coil picks up the heat from your home and moves it to the outdoor condensing unit. The condensing unit fan blows outside air through the condensing coil to remove the heat. The condensing unit houses the three parts replaceable by a DIYer: the AC contactor, the start/run capacitor (s) and the condenser fan motor. The condensing unit also houses the compressor, but only a pro can replace that. The A-coil has no parts that can be serviced by a DIYer.
How to disconnect a condensing unit?
