Air Conditioning Faults & Maintenance tips

Faults due to disuse of the Air Conditioning
Not using things is as harmful as using them wrongly, the air conditioning equipment tends to be off for many months, especially in the winter months it can cause breakdowns, some devices only work one month a year, this disuse is just as harmful than misuse, because the mechanisms are filled with dust and dirt, the tubes are punctured and the gases pass, condense, or escape.
Maintenance is important even if the equipment is not in use. Make sure your equipment is in perfect condition before the hot season begins, if your equipment is not in good condition, in addition to not working, it may work incorrectly, consuming more energy and giving worse results.
Remember, timely maintenance can save you a lot of money, because the sooner incidents are detected, the less serious they are, because if they are left they can cause more serious and damaging breakdowns for your equipment, increasing the price of the repair.






The most common breakdowns in air conditioning equipment are:
The air comes out of room temperature from the air conditioning unit and does not come out cold.
Water comes out of the equipment inside the house.
The leads jump when the air conditioning is turned on.
Causes unusual noises.
Does not turn on the air conditioning equipment or turns on and immediately turns off.
The thermostat does not maintain a constant or defined temperature.
Compressor not working.
There is no gas in the air conditioner or it is leaking.
The digital display indicates an error or an alarm light goes off.
Some areas of the house are hot.
Do not hesitate to contact our air conditioning technical service to carry out a review of your air conditioning equipment and you can be sure that the equipment will work correctly throughout the hot season.


Maintenance tips
Maintenance in the Air Conditioners
Why is good maintenance important for an air conditioner?
Air conditioning maintenance is important for several reasons.
By performing regular maintenance on the air conditioning, we will ensure that it works in perfect condition and we can prevent some of the most common breakdowns caused by use, it is also possible to reduce the consumption of the equipment without losing comfort.

How to perform a good air conditioning maintenance?
To perform proper maintenance, follow these steps:
Air conditioning maintenance. Keep the air conditioning filters clean, these filters are in the indoor unit where the unit takes in the air from inside the house, if these filters are dirty the unit will work harder to obtain the air necessary for the air conditioning process, thus increasing the consumption of the air conditioning equipment. In addition, if the filters are very dirty or broken, it is possible that the air expelled by the equipment is not completely clean.
Make sure that the condensate outlet is free and not clogged, if this tube becomes clogged for any reason, the water produced by the condensation will begin to come out from another place, and normally the only place it finds is the Split itself, so It is possible that the water ends up in the living room of your house. To prevent this, it is enough to make sure that the tube is well, and that if we collect the water in a bottle it does not fill up and that the mouth of the tube does not get covered by the water level.
Even if maintenance is carried out periodically, it is recommended that an air conditioning repair company carry out an annual review before the hot season to check that everything in your air conditioning equipment works well, has enough gas and can work without any problem.

What are the precautions for fresh air system installation

What is a fresh air system?
The fresh air system is an independent air treatment system composed of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system. The ducted fresh air system is composed of a fresh fan and pipe fittings. The outdoor air is purified by the fresh fan and introduced into the room, and the indoor air is exhausted through the pipe;
Introduce fresh air, purify and filter the pollution and bacteria in the air during the process of sending in the air, and at the same time prevent outdoor dust and smog from invading the room, so as to ensure that the air in people's living environment is fresh. So, how to install the fresh air system?




How to install the fresh air system - host installation
1. Host hoisting
· The installation location of the main engine is generally in the ceiling of the bathroom, balcony or kitchen. When installing, it should be noted that it should not be too far away from the air duct, and the machine should be installed in the air duct, and the channel should avoid bends, so as to reduce resistance .
When the main engine is installed, the suspender nut should have safety anti-loosening measures to make it firmly installed and there will be no noise in operation. It should also be noted that an inspection port should be reserved under the junction box of the host to facilitate later installation and maintenance.


2. Pipeline installation
· There should not be too much error in the installation of the pipeline, try to keep it in a horizontal and vertical state, and also ensure that the inner diameter of the pipe is clean and free of debris.
During installation, the tuyere, direction, and pipe diameter of the pipeline must conform to the design drawings, and the installation of the pipeline should be fixed with a support hanger to prevent loosening.


3. Connect the air duct to the host
Generally, the connection between the air duct and the main unit should be connected by a silencer hose or aluminum foil. It should be noted that neither the silencer hose nor the aluminum foil can be twisted, and the degree of tightness between the two should be appropriate.
The connection of the return air pipe should be tight, so as to avoid the reduction of the cross-sectional area caused by the suction deformation.


How to install the fresh air system - air outlet installation
4. Air inlet installation
· Before installing the air inlet, be sure to choose the installation location, it is best to install it under the window sill or a location that is relatively easy to install, and never install it in a dead corner.
The correct installation position can make the indoor dirty air and fresh air form a circulation system, so that the indoor air can be circulated. The air inlet should be installed firmly and stably.


5. Exhaust outlet installation
· For the indoor air outlet, the best installation position is above the outside of the door frame. This installation method makes the exhaust air and fresh air form a ventilation circulation system, so that the indoor air can be well circulated and the indoor air is more fresh.
The air outlet must be installed firmly, and it should be noted that the air outlet should be close to the roof or wall.


How to install the fresh air system - commissioning and acceptance
6. Debugging and acceptance
·Entrust the decoration unit to reserve the location for the fresh air controller and the host power supply, and the location of the host power supply should be reserved within a radius of 1.5m from the host power supply. After the main unit is installed, it should be tested to ensure that the air volume of each air supply port is similar.
The inspection and repair work must be done before the ground decoration layer is completed. The content of the commissioning mainly includes various safety inspections before operation, the trial operation of the fan in the main outdoor unit of the fresh air unit, and checking whether the fresh air system is running smoothly and whether there is any abnormal vibration and sound.
How to install the fresh air system? You can refer to the above installation methods to install the fresh air system. This will keep the indoor air fresh and bring a healthier and more comfortable environment to our lives.
