We received a call from a man who had his air conditioner recently replaced by another contractor but was having problems. When we arrived, we found that the evaporator coil of the old system had not been replaced and was not compatible with the new unit.
If you are having a new system put in, it is very important that you have the old evaporator coil replaced as well even if it is working properly. You will run the risk of developing a compressor problem if you don’t. What’s worse, in most cases your warranty will not cover compressor failure due to an old evaporator coil.
The reason for this issue was the compatibility of the coil with the new air conditioner, not the functionality of the coil itself. However, it will still be beneficial to you to understand other problems that can occur with the coil, seeing as it’s a vital component to your cooling system.
You could have either a starved or flooded evaporator coil. If it’s starved, that means that not enough refrigerant is being supplied through the total coil length, resulting in poor coil operation and too-low heat exchange.
A flooded evaporator coil, on the other hand, is the exact opposite. In this instance, there is too much refrigerant being passed through the evaporator coils. This results in unexpanded liquid being passed onto the suction line and into the compressor.
If you ever have any air conditioner problems that you need repaired, call Arco today and we’ll be right over!
