How to Replace the Condensing Coil of an Air Conditing Compressor How to Replace the Condensing Coil of an Air Conditing Compressor

What You'll Need
Replacement Coil
Stanley knife
Soldering Iron

If you have a problem with the condensing coil of your air conditioning compressor, then you will need to replace it as soon as possible. This coil is on the outside of the compressor, and can be found by looking at the outside unit. The position of the coil should allow you easy access, meaning that you will not have to remove any other parts in order to access it. Replacing the condensing coil should allow your air conditioning compressor to work effectively again.

Step 1 – Check the Condensing Coil

The first thing that you need to do is look at the coil. You should be able to open the doors of the condensing unit, and look at the coil in situ without removing it. Take the opportunity to clean the coil thoroughly, as this is sometimes the cause of the problems. If you are not able to cure the problems in the coil by this method, you will need to look in your owner's manual for the details of your coil part, and then order it through your local home improvement store. You need to get the correct make and model number coil for your air conditioning compressor, otherwise it will not work.

Step 2 - Remove Refrigerant

Before you can begin repair work on your unit, you need to remove all refrigerant from the system. You can connect a refrigerant pump to your unit to remove all of the refrigerant coolant. Pump uses and connections vary quite a bit according to manufacturer, so be certain to read and follow the manufacturer’s instructions for the use of the pump.

Step 3 - Remove the Old Coil

Drain the old tube of freon. Run off the old freon into a plastic tray, and discard this accordingly. Take a Stanley knife, and cut through the tubing which connects the old coil to the air conditioning compressor. You will have to sever both ends of the tube, and then pull out the coil.

Step 4 – Installing the New Coil

Once the old coil has been removed, insert the new one into the same place. Take the tubing at either ends of the new coil, and add a little bit of solder to your soldering iron. Press the iron onto the solder, and hold it long enough to ensure that the new coil is secure. You should then be able to take your hands away from the coil without it falling down.

Step 5 – Add New Refrigerant

You should then add some more refrigerant to the unit. This is the freon which will be warmed and cooled down through the air conditioning process. You should add enough of the freon to ensure that your AC unit works effectively, but not too much, as this can cause leakage. Once you have finished adding the refrigerant to the coil, you should close the unit, and then run your air conditioning compressor for about 10 to 15 minutes. This will ensure that the system is working effectively.
