Comfort inside the home is what each and every one of us strives hard to attain. After a long and tiring day outside at work, who wouldn’t want to relax in a cozy and appropriately cool room? Keeping accuracy of the warmth, and more especially the coldness of a room is the role of an air conditioning system. The system is composed of different air conditioning parts which functions according to their purpose. Imagine how troublesome it could be if you realize that there are some problems on your AC unit and the only choice you have is to hire a technician simply because you have no idea how to fix them. This article highlights the most common AC parts, how they work, and how to fix them Generally speaking, the major AC parts manage the movement of air in two main directions: going in and out. Here are the roles of each part:
This part is in charge of receiving the liquid refrigerant. A very important component of an evaporator is the evaporator coil. If the coil is cooled by gas, it cools the air passing through the fins of the evaporator. On the other hand, the heat that passes through the coil continues the cycle of decreasing air temperature.
The AC evaporator is one of the most vital air conditioning parts.
The most common problems in the evaporator are as follows:
Unpleasant smell – this is oftentimes due to a build-up of bacteria and mold on the fins of the evaporator. The fins also attract gas (water vapor) from the air, and in turn, condensing down the coil and to the drain. The remnant moisture may stay for too long, causing a build-up of moulds and unpleasant smelling bacteria. To avoid this problem, you may need to clean the evaporator fins every now and then, or coat them with a mold protectant.
Evaporator Frost – this happens when the build-up of moisture stays on the evaporator fins for too long. Water can freeze and coat the blades. It may influence the performance of your AC system. A defrosting can be done during a regular check of your AC unit in order to avoid this problem.
Coolant Issues – If the outward appearance of your evaporator may look like it’s in a good condition, but is acting strangely, there may be a problem with the coolant. If the lines of a coolant have a leak, it may cause other evaporator problems. Asking the services of a technician may be the best option in this regard.
The role of the condenser in the system is very important. It facilitates the transfer of heat throughout the other parts of the system.
Here are the most common condenser problems, and guide on how to fix them:
If the condenser fan or the compressor won’t run, make sure to check the thermostat to see if it is turned to cool. The setting of the temperature should be lower than the room temperature which is indicated in the thermostat.
This part is in charge of regulating the flow of refrigerant to the evaporator. The most common problems that you may face with your expansion valve are flooding, starving, and hunting.
The problems mentioned above may be caused by the valve sticking out in the open position. Also, there might be an improper superheat valve settings implemented or an improper location of the bulb.
Generally, the troubleshooting that you can do for the expansion valve is limited. In this case, it is much better, and a lot safer, to hire the assistance of a reliable HVAC technician.
The compressor is the pump that is used to pressurize the refrigerant.
To avoid problems with your compressor, make sure to implement simple checks. The problem may simply be a result of minor faults. Check whether the electrical supply is enough and that the settings are appropriately implemented. Other components such as fans, duct work and filter should be in good condition.
If the internal parts get damaged, the motor windings of the compressor may be burned. Inspecting the overall electrical system regularly will help avoid this problem. But if necessary, you may need an AC compressor replacement.
Caring for your Air Conditioning Parts
Just like any other appliance you have at home, your AC unit needs a regular check-up. Maintenance and occasional repairs should be done to avoid bigger problems to ensue later on. Familiarize yourself with these parts and how to troubleshoot them. However, there are other instances wherein professional help is necessary.
