Air conditioners feature many components that work in harmony to provide cool, comfortable homes and businesses. Understanding the parts of the air conditioner can give you a clearer understanding of how it works and how to better identify the problems the air conditioner can have. Though there are quite a few elements to the air conditioner units, we at Air Supply Air Conditioning & Heating would like to take the opportunity to elaborate on the evaporator of the air conditioner unit.
Function of Air Conditioner Evaporator
Comprised of many coils, the evaporator is located inside the top of the system in most air conditioning units. In liquid form, refrigerant enters the evaporator from the condenser. It is met with low pressure once the liquid refrigerant enters the evaporator. The liquid refrigerant turns into a gas due to the lower pressure. From the air surrounding it, this gas then absorbs heat. The inside of your home is cool as the heat is absorbed. The gas refrigerant returns to the condenser to repeat its cycle from here.
Importance of AC Evaporator
It would be impossible for your air conditioning system to cool the air in your home without the evaporator within the air conditioner unit. The evaporator allows the refrigerant to absorb the heat within your home by changing the refrigerant into its gas form.
Access & Clean Evaporator Coils
The all machinery with moving parts, the evaporator needs maintenance to run smoothly it is important to remember that your evaporator works very hard to keep your home cool. Since the coils can trap dirt which will then prevent the absorption of heat, the first step is keeping the evaporator clean. Throughout the year even in winter, this should be done. The efficiency is limited when the moisture evaporator freezes.
Symptoms of a Bad or Failing Air Conditioner Evaporator
1) AC system is not producing cold air. No cool air is frequently one of the first symptoms of a potential problem with the evaporator. The system’s ability to produce cold air affect if the evaporator temperature switch fails or has any issues that causes it to send an incorrect signal to the AC system.
2) Fluctuating AC temperature. The fluctuating temperatures from the AC system indicates an issue with the evaporator. It can cause the AC temperature to behave erratically if the evaporator temperature sensor sends an incorrect or erratic signal to the computer. Resulting in additional strain on the compressor, and consistently less cool cabin temperatures, the temperature may suddenly alternate between cold and warm.
3) Inactive AC Compressor. A possible problem with the evaporator temperature sensor is when an AC compressor that won’t activate. Should the evaporator fail, it can affect the compressor, which affects the performance of the air conditioner unit.
