How does domestic AC work?
Domestic air conditioning (AC) units work by removing heat and humidity from the indoor air and transferring it outside. By continuously cycling the refrigerant and circulating air, the AC unit maintains a comfortable indoor temperature and humidity level. The thermostat in the AC system helps regulate the temperature by turning the compressor on and off as needed to maintain the desired set point.
Types of Domestic Air Conditioning Units
Window Air Conditioning Units
Window air conditioning units are compact, self-contained systems designed to cool individual rooms or small spaces by fitting into a window or a specially designed wall opening. They are among the most common and affordable types of air conditioners used in homes and small offices.
What does a window air conditioner consist of?
A window air conditioner consist of:
Evaporator Coils: Located on the indoor side, these coils absorb heat from the room air.
- Condenser Coils: Located on the outdoor side, these coils release absorbed heat to the outside air.
- Compressor: Pumps the refrigerant through the system and increases its pressure.
- Fan: Circulates air over the evaporator and condenser coils.
- Thermostat: Controls the temperature by cycling the compressor on and off to maintain the desired room temperature.
- Filters: Remove dust and particles from the air to improve air quality and protect the unit’s components.
What are the advantages of a window air conditioner?
Energy Efficiency: Effective at cooling specific areas, reducing energy consumption compared to cooling an entire house.
Cost–Effective: Typically cheaper to purchase and install than central air conditioning systems.
Ease of Installation: Can be installed in a window or wall opening with minimal modifications.
Portability: Though not as mobile as portable air conditioners, they can be easily removed and relocated if needed.
Split-System Air Conditioning Unit
A split-system air conditioner is a type of air conditioning system that consists of two main units: the indoor unit and the outdoor unit. These systems are typically used for cooling individual rooms or specific areas within a building.
The indoor unit of a split air conditioner consist of:
- Evaporator Coil: This coil absorbs heat from the indoor air.
- Blower/Fan: It circulates the cooled air throughout the room.
- Air Filter: Filters out dust and other particles from the air.
- Thermostat/Control System: Allows users to set and adjust the temperature.
The outdoor unit consist of:
- Compressor: Compresses the refrigerant and pumps it through the system.
- Condenser Coil: Releases the absorbed heat from the indoor unit to the outside air.
- Fan: Helps dissipate the heat from the condenser coil.
- Expansion Valve: Regulates the flow of refrigerant into the evaporator coil.
What are the advantages of a split air conditioner?
Efficiency: Split systems are known to be more energy-efficient than other types of air conditioners.
Quiet Operation: The noisier components, like the compressor, are located outside. As a result, you will have a quieter operation indoors.
Flexibility: These systems can be used for cooling individual rooms or spaces, allowing for more precise temperature control.
Aesthetics: The indoor units often have sleek design and can be mounted on walls or ceilings, making them less obtrusive to their surroundings.
Portable Air Conditioning Units
Portable air conditioners are standalone cooling units designed to cool individual rooms or small spaces. They are known for their mobility, as they can be moved from room to room as needed.

What does a Portable Air Conditioner consist of?
A Portable Air Conditioner consists of:
- Compressor: Compresses the refrigerant and circulates it through the system.
- Evaporator Coil: Absorbs heat from the indoor air, cooling it down.
- Condenser Coil: Releases the absorbed heat to the outside air.
- Fan: Blows the cooled air into the room and helps dissipate heat through the condenser coil.
- Exhaust Hose: Vents hot air out of the room, usually through a window or an opening.
- Drain System: Collects and removes condensation produced during the cooling process, either through a built-in tank or a continuous drain option.
- Control Panel: Allows users to set the desired temperature, fan speed, and operational modes.
What are the advantages of Portable Air Conditioners?
Ease of Installation: No permanent installation required; typically involves just setting up the exhaust hose and plugging in the unit.
Mobility: Easily moved from room to room as needed, providing flexible cooling solutions.
Versatility: Can be used in various settings, including homes, offices, and temporary locations.
Space-Saving: Compact design makes them suitable for small spaces.
Ductless Mini-Split Air Conditioning Units
Ductless mini-split air conditioning units are a type of cooling and heating system that provides individual temperature control in different rooms or zones of a building without the need for ductwork. They are a popular choice for both residential and commercial applications due to their efficiency, flexibility, and ease of installation.
What does a Ductless Mini-Split Air Conditioner consist of?
Ductless Mini-Split Air Conditioners consist of:
Indoor Unit (Evaporator)
This part is mounted on a wall or ceiling within the room being conditioned. It contains the evaporator coil and a fan to distribute cool or warm air.
Outdoor Unit (Condenser/Compressor)
This part is Installed outside the building. It contains the compressor and condenser coil.
Refrigerant Lines
These are flexible tubing that carries refrigerant between the indoor and outdoor units. They include power cables and a condensate drain line.
Remote Control
Remotes allow for adjusting temperature settings, fan speeds, and operating modes.
What are the advantages of Ductless Mini-Split Air Conditioners?
Energy Efficiency: By allowing individual room control, these systems reduce energy waste compared to central air systems. Many models also have high SEER ratings.
Compact Size: Indoor units are sleek and can be mounted high on walls or recessed in ceilings, taking up minimal space.
Flexible Installation: No ductwork is required, making them ideal for older homes, room additions, or buildings without existing ducts.
Zone Control: Each indoor unit can be controlled independently, providing customized comfort in different rooms or zones.
Compact Size: Indoor units are sleek and can be mounted high on walls or recessed in ceilings, taking up minimal space.

Key Factors to Consider When Choosing a Domestic Air Conditioning Unit
- Cooling capacity (BTU)
Cooling capacity, measured in British Thermal Units (BTUs), indicates the amount of heat an air conditioning unit can remove from a space per hour. Selecting the right BTU rating is essential for efficient cooling and comfort. You can do this by matching BTU rating to room size.
| Room size | Required BTU Rating |
| 150-250 sq. ft. | 5,000-6,000 BTUs |
| 250-350 sq. ft. | 7,000-8,000 BTUs |
| 350-450 sq. ft. | 9,000-10,000 BTUs |
| 450-550 sq. ft. | 12,000 BTUs |
Energy efficiency (EER and SEER ratings)
Higher EER, SEER and an Energy Star Rating indicate high energy efficiency.
Noise level
Check the unit’s decibel (dB) rating. Quieter units typically have lower dB ratings.
Installation requirements
Each unit will have different installation method and location:
Window Units: Easy to install but blocks window views.
Split Systems: Requires professional installation.
Portable Units: Simple setup with an exhaust hose.
Central Air Conditioning: Requires ductwork and professional installation.
- Budget considerations
Check for initial purchase price, installation costs, operating costs and maintenance and potential repair costs.
