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 does it mean to replace an evaporator coil?
In some situations, replacing just the evaporator coil means it will “mismatch” your condenser (the outside unit). And if the condenser and evaporator mismatch in either age, SEER or refrigerant, you’re going to run into problems like: We’ll explain what we mean by “mismatching” coils and when you should replace the entire unit versus just ...
What does the evaporator coil do anyway?
Your AC’s evaporator coil is responsible for absorbing the heat and moisture in your home.
How does an evaporator coil work?
Here’s how it works: the evaporator coils are filled with super cold refrigerant. As warm air from inside your home passes over these coils, the refrigerant absorbs the heat and moisture from the air. Evaporator dehumidification process.
How many coils does an AC unit have?
Well, your AC has two coils: The evaporator coil or the “inside coil”. The condenser coil or the “outside coil”. These coils are both housed within the same AC unit but are still separate components that must work closely together to cool your home.
What refrigerant does an AC unit use?
Your AC unit uses R-22. If your unit uses R-22, your best option is to replace the entire unit for one that uses R-410A refrigerant. You see, R-22 is an older refrigerant that’s harmful to the environment. Because of this, most countries have slowly phased out its use.
How long does an air conditioner last?

How does a cool refrigerant work?
The cool refrigerant can then absorb heat from the warm air brought into the air conditioner unit by the blower fan. As the water vapor from this warm air hits the coils, it condenses and drips into the drip pan. These steps allow the air conditioner to cool the air and remove excess moisture. 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.
