Recharging your AC systems gas

If your AC has been installed by a technical, changing gas is easy. This only becomes easier if the tech actually did a proper installation. Some techs do a more sloppy job than others making it the reason why aircon not cold. Before you learn to recharge your AC, you must make sure that the outside and inside units are properly connected and in no way faulty. Otherwise recharging can be a nightmare. Whenever you can, you must learn a couple of things about your AC. You can start by recharging its gas. Here are a couple of things you need to know to be able to charge your AC’s gas.

First, you need to know that recharging your AC in actual since does not happen. When we say we have to charge our air conditioning system, it means we have to circulate the condensed air throughout both the inside and the outside units. This is usually due to the distance of the units from each other. For example, if you internal unit is installed 3 meters away from the external unit, you might need to recharge often. This can be remedied by finding a spot where you can put the air conditioning systems units near each other.

Second, you need to locate the valves for recharging the gas. It is usually located at the outdoor units end. Placements vary from manufacturer to manufacturer so carefully read your manual and study the units. These valves are usually located at the outdoor unit’s end. When you locate the valves, you should see them close. One of the valves are supplying gas from the unit inside going outside and the other one is to receive the gas returning from the indoor unit to the outdoor one. These valves are vital for you to charge the gas. When charging, slowly open these valves. This will distribute the refrigerant throughout the whole unit. It includes the indoor and outdoor unit as well as the tubing connecting them.

From here onward, you have to be careful with leakage. Gas leaking from your air conditioning unit can be costly. You have to be sure to check for leakage.  These leaks usually are at the joints of the tubing connecting the indoor and outdoor units. A simple way to check if there is a leak is to apply soap and look for bubbles. You can also use a cup with water. By placing the cup near the tubing, you can identify if there is indeed a leak. The water should always be steady when placed near the tube. If you find any ripples to the water when near the tube, this can indicate leakage. You cannot start your air conditioning system if this happens.

Provided that everything went well and there were no mishaps, you can successfully start you AC. Continue to monitor your Air conditioning system for a couple of days. Make sure to check from time to time the tubing as well as the units.

Overall, it is pretty simple to charge your AC but you have to be careful along the way. If you are not confident enough to do it, it is better to have a technician do it instead.

So, let us start figuring out what could be wrong with our air conditioning device

You might be cleaning your air conditioner often, but mites and other insects can still get through inside and attack the ducts of the AC. When it has leaked, it will wind up with the work of the air conditioner. The hole in the duct will result in the decrease of the cool airflow of the air conditioner, but this is easy to fix.

Another vital part of the air conditioner is the coil. It must bring out the warmth out of the room, and since the coil is on the outdoor portion of the house, it is more prone to harmful elements like dirt that can impede its work. That is why we need to clean the coil on a regular basis to prevent poor airflow despite the air conditioning doubled effort to cool the room.With this, you need to know more about chemical cleaning.

  1. Unfit Air Conditioning Unit

Sometimes you think it is better to have a big unit to have a cooler environment, but this is wrong with it comes to the air conditioner. A big unit with a small area to cool tends to make the air conditioner work inefficiently because the air cycle is just too frequent. This will make the room hotter than it is supposed to be.
