How to maintain an air conditioner?

Buying good air conditioning systems means making significant investment of money. That’s
why it is advisable to know how to take good care for it so the air conditioner can function
properly for a long period of time. Before choosing the perfect device that best suits your
needs, it is advisable to read about the various options, offered by the market, learn about
the different brands with their new models. It is also important to know how to calculate the
power needed for the room in which we want to install and to choose the most efficient model
so that the electricity bill does not increase.
An important part of your purchase is to choose the company that will install the air
conditioner and will be responsible for the subsequent maintenance.
Once your air conditioner is installed, it is important that you follow the manufacturer’s
recommendations. Maintenance is recommended every year, also to replace the filters
where the machine accumulates mold and bacteria, which can be harmful for customers’
If we do not do these annual technical reviews, the air conditioner may break.
One of the most common cases when our device does not work or does not cool is that it
lacks refrigerant, which may be due to leakage. In this case it is very important to call our
technician to come and check the device. If it is confirmed that there is a gas leakage, the
reason for that malfunction must be found, which in most cases is due to leakage of gas. It is
important for the technicians to find and correct the leakage, otherwise soon after recharging,
we will have to call the technicians again and pay them again.
It is important not to be deceived. Proper installation of the air conditioner should not lead to
gas leakage.
The moments that need to be taken into consideration is when we want to fill our air
conditioner with gas.

       ·   It is important to consider if there is a lack of gas.

       ·  Once we have solved the leakage problem, we need to vacuum the system to remove the air and humidity from inside the pipes.

       ·  The next step is to refill the air conditioner. The new air conditioners use the refrigerant gas R410A. This type of gas does not damage the ozone layer and improves the performance of compressor. Note                  that this type of gas is always charges in liquid state. You should the exact amount needed.

Different types of refrigeration gas for air conditioning

Cooling gases are believed to cause an increase in the temperature of the planet as they damage the ozone layer. For this reason, new types have been put on sale, which effect on the ozone layer is much smaller. Hydrofluorocarbons (HFC) are made the same way. The third generation, created to replace CFCs and HCFCs. Although it is considered not to be harmful to the ozone layer the presence of fluorine in its components contributes to global warming. Therefore from next year many of them will be forbidden and new substitutes will emerge.

Now the most commonly used freons are R410A, R134A, R404A, R422D, R407C, R414A, R427A etc.

Most of the new air conditioners use the R410A Freon, because they have a high cooling capacity. This is a substitute for the old gas R22, which since 1.01.2004 has been forbidden. Works at a higher pressure with synthetic POE oil. This gas does not damage the ozone layer, and the azotope mixture produces HFC gases. Characterized with low risk because it is not flammable. It is very important to know that this gas should be charged in liquid form, using the necessary tools.

The most common used refrigerant for car air conditioners is the R134A. This gas allows it to operate at a lower pressure than other gases, it is very energy efficient at low or medium temperatures, allowing it to be used in a variety of applications. This Freon works with synthetic POE oil.

The search for working with one refrigerant on low evaporation equipment creates the R404A. This is the indirect replacement for R502 and is used in new refrigeration equipment at low or medium temperatures such as water coolers, cold rooms or cold storages. This refrigerant should always be charged in the liquid state and use synthetic POE oil.

Freon R422D is designed to be a direct substitute for R22. This is a mixture of gases that do not damage the ozone layer. It can be used in refrigeration systems with medium temperatures and internal and commercial air conditioning systems. In the case of leakage, the equipment can be charged without any problems. It is compatible with the manufacturer’s original oil and the discharge temperatures are much lower, which contributes to the life of the compressor. Always charge in the liquid state.
