Air compressor, a vital and primary component of the air conditioner, is termed a the heart of it. It serves as a crucial component which regulates the cooling cycle. Moreover, it is responsible for providing the right concentration of refrigerant so that optimal cooling is achieved.

Furthermore, this carries the important task of converting the energy from components to power to make the room cool. In short, without an air compressor, it will not be possible to provide cold air. In addition to that, this expensive component requires regular maintenance. Therefore, you need to know where the air compressor is located in an air compressor.

The location of Air Compressor in An Air Conditioner

The location of air compressor is crucial. It can’t simply be placed anywhere. You need to know the right place. Need not to worry because we are here to assist you about it all. Air compressor requires outside air. It requires that to avoid overheating and proper circulation of the refrigerant. In order to accomplish that, you need to place it outside the home.

This is placed on the rear side of the air conditioner, right outside the wall. There are certain other components of the air conditioners which are placed outside the home. These include the following

• Condenser
• Fan 
• The coil of the condenser 

The connection is another important step which should be paid great attention to. You can connect the whole outside unit consisting of these parts to the inside conditioner via refrigerant tube. This tube is made up of copper which is an excellent conductor of electricity, heat and has great strength. This demonstrates resilience and remarkable durability. This provides an efficient connection which aids in absorbing the hot air which comes from the inside unit. It then is cooled by refrigerant and the whole cooling cycle.

Frequently Asked Questions 

1. How do I know if my home AC compressor is bad?

There are usual signs and warnings which indicate whether your AC compressor is bad or not. You need to check for those specific signs. The signs which indicate whether the air compressor is bad are following.

• The noises which are produced by the air compressor. These make the sounds like growling or either screeching. Other noises include clattering sounds. The reason for thee clattering noises is electrical failures.
• The AC takes longer than usual to start and doesn’t reach right temperature.
• You do not notice any cold air blowing from the air conditioner.
• Any sort of problems associated with circuit breaker.
• The airflow is severely diminished.

2. Is the AC compressor inside the condenser?

The air conditioner has several important parts. The major ones include AC compressor and the condenser. The compressor is usually placed outside the room. The main function of the compressor involves cooling. It cools the air to the temperature assigned by the user. Compressor carries the important job of getting all the refrigerant air. This is cooled air which is then compressed so that it converts into the liquid. This liquid then gets transferred inside the room. This then reaches the condenser. Therefore, the compressor is not inside the condenser as compressor is outside the home.

3. What happens when the AC compressor goes out?

The effects of air compressor failing are quite significant. Therefore one needs to maintain the air compressor routinely so that it works longer and doesn’t fail out easily. Further, it should be kept in optimal conditions. The failing will result in lesser pressure of the air. The vents will not throw out significant air.

Moreover, there will hardly be any cool air coming from the vents. Mostly, all the air will be warm. The system will not contribute towards lowering the temperature of the room. Also, the refrigerant will not be involved in the cycle. This all will cause more electricity to be used and larger power consumption

During the warmer months, your air conditioner unit is the only thing keeping you sane in the house and at work. If something goes wrong with that unit, what do you do? Get a new one?

You need to pull on it in order to release the pressure. Make sure you have safety goggles on when doing this.

Also, shield the valve using one hand to deflect the air and use the other hand for pulling the ring. The released air might stir up debris or dust which can go into your eyes and cause irritation. You need to keep pulling on the ring to release the pressure. Make sure you keep doing this until the pressure of the unit is lowered to 10 PSI.

• Release the air compressor’s drain valve

Finally, it’s time to release the moisture which has built up inside the air compressor’s tank. The drain valve is usually below the tank on most porter cable air compressors. Locate it in order to begin draining. Once you find the drain valve, open it up by twisting it in one direction and drain out the moisture by letting it flow out. Make sure that all the moisture has properly drained out by tilting the tanks slightly back and forth. Do this gently because you do not want to damage the air compressor.

• Close the air compressor’s drain valve

After making sure that all the moisture has been properly drained out, close up the drain valve. This is the final step of the process so make sure you do it properly. Make sure that it is shut tight because leaving it loose might be dangerous for the unit.

• Air compressor is ready

Now the air compressor is ready for use. You may switch it on immediately if you have some work that you need to do right away. You can also just store it if you’re not using it immediately. Either way, your air compressor has now been drained and can be used safely.

Tips to follow

Follow these few simple tips in order to ensure a safe and efficient draining process.

• Wear safety gloves

The tank drain might not be very clean so make sure you wear gloves before you begin the draining process. This will also help protect your hands in case any part of the air compressor is too hot.
