What are the parts of an air conditioner?
An air conditioner has 5 main parts: 1. Refrigerant. Refrigerant (also known as coolant or by its brand name Freon®) is a special fluid that is vital to cooling and freezing technology. It operates on a closed loop and carries heat from the inside of your building to the outside.
How does the refrigerant cycle work?
How the Refrigeration Cycle Works Summary. The return vents, located inside your home, suck in hot air from inside the room. The refrigerant picks up heat as air flows over the evaporator coils, which are very cold.
Why do we use refrigerant?
We use refrigerant because it changes states from liquid to vapor at convenient temperatures for the refrigeration cycle. Refrigerant moves through an air conditioner’s cooling tubes and copper coils, connecting the inside unit to the outside unit. It absorbs heat from your indoor air, changing states from gas to liquid.
How does refrigerant travel?
After absorbing heat from the inside air, the refrigerant travels to the outdoor unit where the heat is pushed outdoors. Once the refrigerant has dispersed its heat outdoors, it changes back to its gaseous state and travels back indoors.
Why do we need a compressor?

Can you get ice on your AC?
Ice should never appear on your AC. If it starts to develop along the indoor evaporator coil, shut off the air conditioner and get repair technicians in. They’ll defrost the coil and find out what other repairs need to be done to stop it from happening again.
Can you replace refrigerant in an AC?
Refrigerant doesn’t get used up as an AC runs, so ideally you should never have to have replacement refrigerant put in to recharge the system. But leaks can happen along the refrigerant lines, causing a drop in charge, loss of cooling power, and eventually a full system breakdown. It’s hard to prevent these leaks because they’re the result of corrosion from chemicals in your household air. However, you may catch them early enough to make the repair simpler: don’t hesitate to call for repairs if you hear hissing from the cabinets or notice a rise in temperatures.
Where is the HVAC system located?
This element of the HVAC system is located on the “cold” side of the system inside the home or business. It is set of coils over which air is blown and then delivered to the living space via the ductwork. It gains its name from the fact it turns a compressed liquid into a gas (evaporation) while operating.
