Some FAQ about AC Servicing & Repairing processes and steps and their simplified answers

Question 1: Why is nitrogen used to repair air conditioners?
Answer: Nitrogen is commonly used to repair air conditioners because it is an inert gas that is non-reactive with other substances, which makes it ideal for purging and pressurizing the refrigerant lines. During the repair process, it’s important to remove any air or moisture from the refrigerant lines, as they can cause damage or reduced efficiency to the air conditioning system. Nitrogen is also used to leak test the system after repairs have been made, as it can easily be detected if it escapes through any leaks or cracks in the refrigerant lines. Overall, using nitrogen during air conditioner repairs helps to ensure the system operates efficiently and reliably.

Question 2: Why is nitrogen used to check air conditioner leakage?
Answer: Nitrogen is commonly used to check for air conditioner leakage because it is an inert gas that is readily available and safe to use. When checking for leaks in an air conditioning system, nitrogen is pressurized into the system, and then the pressure is monitored to see if it drops, which indicates a leak. Nitrogen is preferred over other gases because it is non-reactive and will not interact with the refrigerant or other components of the air conditioning system, which could cause damage or inaccurate test results. Additionally, nitrogen is less expensive and more readily available than other leak detection gases, making it a cost-effective option for leak testing. Overall, using nitrogen to check for air conditioner leakage is a safe, effective, and affordable way to ensure the proper functioning of an air conditioning system.

Question 3: What can be the harm of checking leakage with air pressure in air conditioner?
Answer: Checking for air conditioner leakage with air pressure can be harmful because air contains moisture and other contaminants that can damage the air conditioning system. Moisture in the air can react with the refrigerant, which can cause the formation of acids and other corrosive substances that can damage the system’s components. Additionally, the use of compressed air can introduce dirt, dust, and other debris into the air conditioning system, which can clog the system’s filters and cause damage to the compressor or other components. Finally, compressed air can also create pressure that exceeds the manufacturer’s recommended limits, which can damage the system’s components and create safety hazards. For these reasons, it is not recommended to use compressed air to check for air conditioner leakage, and it is preferable to use nitrogen or other inert gases that do not pose these risks.

Question 4: Does the indoor unit of the air conditioner get damaged due to the drain?
The drain of an air conditioner’s indoor unit is designed to remove the condensation that is produced as the unit cools and dehumidifies the air. If the drain is not functioning properly, it can lead to water buildup in the unit, which can potentially cause damage over time.

If the drain becomes clogged or blocked, water can back up into the unit and cause damage to the internal components, such as the fan motor, control board, and other electrical components. In addition, the excess moisture can promote the growth of mold and mildew, which can cause health problems and further damage to the unit.

To prevent damage from the drain, it’s important to ensure that the drain is functioning properly and is not clogged or blocked. Regular maintenance of your air conditioning system can help ensure that the drain is clear and free from debris. Additionally, if you notice any signs of water buildup or leakage around the indoor unit, it’s important to have it inspected by a qualified technician to address the issue and prevent further damage.

Why does the problem of air conditioner leakage due to polluted environment persist?

The problem of air conditioner leakage due to a polluted environment can occur due to a number of factors, including:

  1. Corrosion of the unit’s components: When the air conditioner is exposed to a polluted environment, such as one with high levels of pollutants or chemicals, it can lead to corrosion of the unit’s components, including the coils, fins, and refrigerant lines. This corrosion can cause small leaks to develop over time, which can eventually lead to a larger refrigerant leak.
  2. Clogging of the drain line: In a polluted environment, the drain line of the air conditioner can become clogged with debris, such as dirt, dust, and other pollutants. This can cause the drain line to back up, leading to water leakage from the indoor unit.
  3. Improper installation: If the air conditioner is not installed properly in a polluted environment, it can be more prone to leaks and other problems. For example, if the unit is not level or if the refrigerant lines are not properly sealed, it can cause refrigerant leaks to occur.

To prevent air conditioner leakage in a polluted environment, it’s important to take steps to reduce the amount of pollutants and debris that are present around the unit. This can include regularly cleaning the unit and the area around it, as well as ensuring that the unit is installed properly and maintained regularly. If you suspect that your air conditioner has a refrigerant leak or other problem, it’s important to have it inspected and repaired by a qualified technician as soon as possible to prevent further damage to the unit and to ensure that it is operating safely and efficiently.

Our Opinion: Keeping in mind the changing weather, if you are using AC, then keep the temperature of AC 1 degree or at most two degrees less than the room temperature

As the world continues to grapple with climate change, we are seeing increasingly extreme weather patterns that are becoming more frequent and intense. This means that temperatures are becoming more difficult to regulate, and more people are turning to air conditioning to keep their homes and offices comfortable. However, using air conditioning excessively can contribute to global warming, which is why it’s important to use it wisely. One way to do this is to keep the temperature of your AC unit 1 degree or at most 2 degrees less than the room temperature.

Why is this important? First of all, keeping the temperature difference small can help reduce the amount of energy that your AC unit uses. The larger the difference between the room temperature and the AC temperature, the harder the unit has to work to cool the air, which in turn uses more energy and leads to higher electricity bills. By keeping the temperature difference small, you can help reduce your energy consumption and save money on your bills.


Secondly, using your AC unit excessively can contribute to global warming by releasing greenhouse gases into the atmosphere. AC units use refrigerants to cool the air, and these refrigerants can contribute to global warming if they leak out of the unit. By using your AC unit responsibly and keeping the temperature difference small, you can help reduce your carbon footprint and contribute to a more sustainable future.

So, how do you keep the temperature difference small? The easiest way is to set your AC unit to a temperature that is just a degree or two cooler than the room temperature. For example, if the room temperature is 75 degrees Fahrenheit, you might set your AC unit to 73 or 74 degrees Fahrenheit. This will still provide a comfortable environment, but it will reduce the energy consumption of the unit and help reduce your carbon footprint.

Another way to keep your energy consumption and carbon footprint low is to use a programmable thermostat. These devices allow you to set different temperatures for different times of day, so you can set your AC unit to run less frequently when you’re not home or when the weather is cooler. This can help you save money on your energy bills and reduce your environmental impact.

In conclusion, keeping the temperature of your AC unit just a degree or two cooler than the room temperature is a simple but effective way to reduce your energy consumption and carbon footprint. By using your AC unit responsibly and making small changes to your habits, you can help create a more sustainable future for everyone.
