The evaporator coil is an important component of a refrigeration system. It extracts heat from the refrigerant circuit and transfers it to the room air. This allows the refrigerant to be cooled and the process to be repeated. The evaporator coil is made of aluminum tubes that are pitched in a serpentine pattern. They are mounted in a rectangular sheet-metal cabinet. Warm room air is drawn over the tubes and the heat is extracted from the refrigerant. The refrigerant is then pumped to the condenser coil where it is cooled and the process is repeated.
How to Diagnose and Fix Problems With Evaporator Coils
If you’re having problems with your evaporator coils, you’re not alone. These are responsible for cooling the air in your home or business, and when they’re not working properly, it can be a huge headache. There are a few things that you can do to try and fix the issue yourself, but if those don’t work, you may need to call in a professional. Fortunately, diagnosing and fixing problems with coils is a relatively easy process.
Identify the problem.
The first step is to determine whether the problem is with the coils themselves or with another component of your refrigeration system. To do this, you’ll need to inspect the coils for any signs of damage or obstruction.
If the coils are dirty or blocked, they’ll need to be cleaned or cleared before the system can be effectively repaired. Coil cleaning can be done with a variety of methods, including a coil brush, a vacuum cleaner, or a coil cleaning chemical.
Once the coils are clean, the blocked or dirty areas can be cleared with a shop vacuum, compressed air, or a coil clearing chemical. This debris can include leaves, dirt, or other debris. Remove any obstructions you find and then test the unit to see if it is now functioning properly. If it is not, you may need to call a professional to inspect and repair your cooling system. After the coils are clean and clear, the system can be effectively repaired.
Check the compressor.
If you’ve determined that the coils are not the problem and the refrigerant is correct, you’ll need to check the compressor. The compressor is what creates the cooling effect in your air conditioner. If the compressor is not running, the system will need to be replaced. Compressors can start having problems for a number of reasons—and it’s not always easy to determine what the issue is.
Some common problems that can occur with compressors include:
- Electrical issues
- Worn bearings
- Faulty switches
- Leaking refrigerant
If the compressor is running, you’ll need to check the condenser. The condenser is a large metal case that looks like a large radiator. The condenser is responsible for cooling the refrigerant after it has been compressed.
If the condenser is not clean, the system will need to be cleaned. The condenser is the part of the air conditioner that is responsible for releasing the heat that has been absorbed by the refrigerant. If it is not clean, the unit will not be able to function properly. If the condenser is clean, the system will need to be evacuated and recharged.
Evacuate and recharge.
To evacuate the system, the technician will need to remove all of the refrigerant. This can be done by using a vacuum pump. Once the refrigerant has been removed, the technician will need to charge the system with the new refrigerant. This can be done by using a charging hose.
If you’re not comfortable cleaning or replacing them yourself, you can always call a professional to do the job for you. By following these simple steps, you can quickly and easily diagnose and fix any problems with your coils.
