So, your air conditioning unit is no longer blowing cold air - this likely means it’s time to replace the evaporator coil. The evaporator coil, also known as the condenser coil, plays a central part in cooling the warm air that circulates within the air conditioner. So, if you find that your air conditioning doesn’t seem to be as cool as it once was - it’s likely to be a problem with the evaporator coil.
At BOXT, we highly recommend that repairs should be carried out by a professional, but if you are somewhat experienced and want to try it for yourself then here’s what to do. With the right knowledge, replacing an evaporator coil can be pretty simple.
Besides the air conditioner no longer blowing cool air, leaks are another sign that your evaporator coil needs replacing. If you find that there are leaks around your air conditioning units, closely inspect the condenser coil for any damage. If the coil is cracked or damaged in any way, it needs replacing.
Not only is replacing the evaporator coil a lengthy job, the cooling agent will need to be disposed of correctly without it leaking into the environment as this can lead to all sorts of fines. It is always better to contact a professional if you are having problems with your air conditioning.
Before you do this - turn off the air conditioning. First you should cut the inbound and exit tubes, but be careful - the gas will begin to leak. If you are unsure of how to dispose of the refrigerant gas you should contact an expert.
Insert the new coil into the existing ports and solder this into place.
Vacuum out any air from the lines. If the coolant is not at the correct level - top it up.
To test that the air conditioner is working properly, turn it back on, and you are all set to go! If, in the unlikely case that your air conditioning does not turn back on, inspect the unit for any further problems or call a professional to help.
