The cooling system removes the warm air inside your home and pumps it outside while releasing cool air back into the room, reducing the temperature. They function in this principle because liquids absorb heat as they become gaseous.

Like your standard refrigerator, air conditioning works by absorbing heat inside the unit and removing it from the room. Contact a professional for ductless mini-split repair in Hemet, CA, if your AC has gone faulty. Here’s how it works:

  • The system begins by drawing warm air from the room into itself.
  • The air flows over the cold evaporator pipes inside, cooling the air down while a dehumidifier removes excess moisture.
  • The coolant flowing through the chiller pipes absorbs the heat from the air blowing past and evaporates, turning from a cool liquid to a warm gas.
  • A compressor unit and a condenser turn the warm air into a cool liquid by pumping it outside.
  • The cold air is then recirculated into the room, mixing with the existing air and lowering the temperature and humidity.

How Different Air Conditioners Work

Air conditioners can be divided into two types: central cooling systems and ductless split systems. Though both systems are designed to cool your home, they operate vastly differently.

Central Cooling Systems

A central air conditioner is designed to cool your entire home. They do this by distributing cool air through your ducts, so the air reaches every room in the house. Except for packaged units located outside the home, central air conditioners consist of an outdoor and indoor section connected by copper tubes.

The central air conditioning units are larger than those ductless systems because they cool entire homes. There is a maximum size of 1.5 tons for central air conditioners. In the spring and summer, these units can reach up to 22 SEER, or Seasonal Energy Efficiency Ratio.

The Department of Energy specifies that the minimum SEER rating in the United States is 14. While central air conditioners can cool your entire home, they’re not always the most energy-efficient option and require a lot of energy.

Ductless Split Systems

A ductless system is designed to cool only one room or part of your house rather than the entire house. Unlike central air conditioning, ductless systems allow air to flow through indoor units into individual rooms rather than through ductwork throughout the house.

The indoor and outdoor components of ductless systems are not equal, as in central cooling. An indoor unit can replace up to five outdoor units in ductless systems. The result is that up to five units can be installed throughout a home to cool up to five rooms without ductwork.

The smallest of these units has a capacity of .75 tons because they are designed to cool smaller spaces. The SEER of ductless split systems can reach up to 33, making them much more energy-efficient than central cooling systems.


Despite their higher initial costs, they will likely lower your energy bill. For more information on central and ductless AC repair, contact AQS Heating & Air Conditioning.
