The following are some common Hawaii air conditioning issues:
- Poorly charged system.  If a system is not properly charged with refrigerant it will not be able to efficiently remove heat and consequently won't cool your home.
- Outside fan not working.  The outside condenser fan removes heat from the compressor and keeps the refrigerant cool.  If it stops working your system won't work either.  There are several reasons your fan may stop working; a faulty capacitor, a bad motor bearing, or not enough power to the system.  A bad condenser fan can put undue strain on your compressor and cause that to fail.
- Rooms not cooling.  Normally this is due to poor duct design by the installation crew, an air leak or a damaged air duct.
- Air conditioner blowing but the air isn't cold.  This is the number one reason we get calls.  This may be due to low power, a thermostat problem, a low system charge or problems with air filters.
- Dirty air filters.  Most systems have several filters that need to be routinely serviced.  Air filters are relatively inexpensive but failure to replace them can cause other system malfunctions.

Size Does Matter

When it comes to air conditioning systems, size does matter.  Your Hawaii air conditioning system should have one liter of volume for every 1000 square feet in your home.  If you don't have that, then maybe you need to upgrade your air conditioning system.

How Does Air Conditioning Work?

In this day and age in Hawaii having an air conditioning system in your household is becoming more of the norm. Hawaii air conditioning provides households with a much-needed reprieve from hot and humid days. Air conditioners are also widely used in many commercial establishments to increase comfort, reduce heat stress on delicate machinery like computers, and lessen food spoilage in restaurants and grocery stores.

However, despite the fact that air conditioners are commonly used in our daily lives, it’s often still a mystery how air conditioning works.  What exactly are the internal processes involved that cool the air inside your home?  Hopefully the following article will help reveal the mystery around how your Hawaii air conditioner works.
 
Step 1: Evaporator Coil Absorbs the Heat
 
The standard air conditioning unit has three (3) main parts: compressor, condenser, and evaporator. The compressor and condenser are both located in the outside part of the air conditioner, while the evaporator is usually placed inside the air handler or attached to the furnace.
 
The evaporator coil, also known as the evaporator core, works by absorbing heat from the area that is being cooled. The evaporator coil is usually located near the air handler where the blower fan is placed. This is where the cooling happens in an air conditioner and is also responsible for keeping your home cool and comfortable. As the hot air passes over the cold coils, heat is being pulled out of the area, which causes water vapor to condense out of the air and onto the evaporator coils.
 
Step 2: Preparing the Refrigerant Temperature
 
After the evaporator coil absorbs the heat from the area, it then changes into a gaseous state and continues to travel toward the compressor. The compressor is the heart of every air conditioning unit, and it acts as a pump that causes the refrigerant to flow through the system. After absorbing the heat from the air, the compressor then raises the temperature and pressure of the air in order to release cool air into the same area where the hot air was collected.
 
Step 3: Transferring the Heat Outside
 
All the extra heat created by compressing the gas is then transferred outside with the help of a second fan and a second set of coils called condenser coils. The hot pressurized air is then transferred to the condenser by the second fan where the heat is removed by the condensation of the air. Over time, the heat or the warm air inside the household or building is gradually transferred away into the outside air.
 
Just like how the coolant flows through a compressor and some condensing pipes in refrigerator units. The only difference between air conditioners and refrigerators is that the role of a refrigerator is to cool a small, insulated space, while an air conditioner is intended to raise the temperature of your entire room, home, or office.


Step 4: The Cycle Continues
 
In the final step, the cycle goes on until the temperature in your house or office reaches your desired point. As the gas cools, it goes back to its liquid state, and the entire process of heat absorption, compression, and transition back to liquid starts over again. Most systems can detect the temperature of the room and once it has reached the desired point, it will automatically stop the process and will restart once the temperature has changed.
 
 
Air conditioners come in various different shapes and sizes, but they all operate on the same fundamental premise. In a nutshell, an air conditioner works by collecting hot air from a given area, processing it with the help of a refrigerant and coils to release cool air into the same area where the hot air has originally been detected.
​
At this point, you probably know the basic steps on how the air conditioning system works. But if you have more queries or you just simply want to feed your curiosity and know more about Hawaii air conditioning, feel free to contact us and we'd love to hear from you.
