Repairing Home Office Air Conditioner in Erakala
The client has a home office air conditioner that was leaking. They also wanted the main bedroom air conditioner cleaned.
We inspected the air conditioner that was in the home office. We found a refrigerant leak in the indoor unit at the suction pipe flare. The metal tube that joins the outdoor unit compressor’s evaporator coil is known as the air conditioner suction line. Because it draws air through itself to generate a vacuum, it is also known as a suction line. The air heats up and loses density relative to the surrounding air as it is drawn along the line.
We tightened the flare on the pipe and then ran a pressure test using dry nitrogen. An efficient way to confirm that an air conditioning system is leak-free is with dry nitrogen.
Compared to a standing vacuum test, which is usually carried out following evacuation, it is more dependable. When a system is pressure tested using dry nitrogen, it is tested at positive pressure, which is the system’s typical working condition. We then vacuumed the aircon system and charged it with 1.2kg of R410a refrigerant.
After completing every step, we tested the air conditioning system, and it was operating at its typical pace.
Cleaning the Bedroom Air Conditioner
We also pressure tested the bedroom air conditioner and it was running at its optimum performance. However, dust and grime were beginning to appear on the louvres. fan blades and the inside of the aircon unit. We then applied a full wet service to clean the system.
What is an air conditioner wet service?
An air conditioner wet service refers to the comprehensive cleaning and maintenance of an air conditioning system, focusing particularly on parts that come into contact with moisture, such as the evaporator coil, condenser coil, filters, and drainage system. Over time, dust, dirt, and mould can accumulate on these wet components, reducing the system’s efficiency and potentially causing health concerns like poor air quality.
The wet service process typically involves:
- Cleaning the evaporator and condenser coils: These coils are cleaned using water and specialized cleaning agents to remove any dirt, grime, and debris that can reduce heat transfer efficiency.
- Flushing the drain line and drip tray: The drain line and drip tray can often get clogged with algae, mould, or dirt, which can lead to water leakage. Wet service includes flushing and cleaning these parts to ensure proper drainage.
- Filter cleaning: The filters are removed and cleaned thoroughly with water to ensure they are free of dust and particles that could reduce airflow.
- Checking refrigerant levels and airflow: The system’s refrigerant levels and airflow may also be inspected and adjusted during a wet service.
This type of service is essential for maintaining air quality, ensuring the unit operates efficiently, and preventing water-related issues such as leaks and mould growth inside the air conditioning system.
