When the heat starts creeping up, the only thing on most of our minds is the sweet relief of air conditioning. We all know how wonderful it feels to step out of the hot, sticky air and into a nicely chilled room. But have you ever stopped to think about the different types of air conditioning systems that exist out there? That’s right, there’s more than just one type of AC unit, and each one comes with its own set of pros and cons. So what are the three types of air conditioning system out there? Allow me to enlighten you.
First up, we’ve got the window air conditioner. This is probably the most common type of AC unit, and you’ve likely seen one hanging out of a window at some point in your life. These units are fairly small and are designed to cool a single room at a time. They’re fairly affordable, easy to install, and relatively energy-efficient. However, they can be a bit on the loud side and may not do a great job of cooling larger spaces.
Next, we’ve got the central air conditioning system. If you’ve got a larger home or want to cool multiple rooms at once, this is likely the type of system you’ll be looking at. Central air systems are designed to cool the entire house at once and use a series of ducts to distribute the cool air throughout the building. They’re efficient and quiet, but can be fairly pricey and require professional installation.
Finally, we’ve got the portable air conditioner. These AC units are designed to be moved around the house and can be a great option for people who don’t want to deal with installing something permanent. They’re relatively affordable and easy to move, but may not be as energy-efficient as some other types of AC units.
Centralized air conditioning
Centralized air conditioning is a popular option for large commercial buildings, such as office towers and shopping malls, as well as homes with multiple rooms. This type of air conditioning system involves a unit that is installed outside of the building and connected to a series of ducts that run throughout the interior, delivering cool air through vents in each room.
There are three main components of a centralized air conditioning system:
- The compressor, which is located outside the building and pumps refrigerant through the system
- The evaporator, which is typically located in the basement or crawlspace and draws warm air from inside the building across a series of refrigerant coils, cooling the air and removing humidity
- The ductwork, which is installed in the walls, floors, or ceilings and distributes cool air throughout the building
Centralized air conditioning systems offer a number of benefits:
- They allow for consistent, even cooling throughout the building
- They are relatively easy to maintain and can last for many years with proper upkeep
- They are often more energy-efficient than window or portable units, as they cool entire buildings rather than individual rooms
However, there are also some drawbacks to centralized air conditioning systems. They can be expensive to install, and require a large amount of space for the outdoor unit and ductwork. Additionally, if the system is not sized properly for the building, it may struggle to cool the space effectively.
If you’re considering a centralized air conditioning system for your home or business, it’s important to consult with a professional HVAC technician to ensure that the system is properly sized and installed.
Split Air Conditioning
Split air conditioning is one of the most commonly used air conditioning systems today because of its efficiency and cost-effectiveness. As the name suggests, this type of system is divided into two separate units – one indoor and one outdoor. The indoor unit houses the evaporator coil while the outdoor unit contains the compressor, condenser coil, and expansion coil. Here is a closer look at the components of a split air conditioning system:
- Indoor unit: This unit is usually installed on a wall and contains the evaporator coil, air filter, and blower. The evaporator coil cools the air and removes moisture from it. The air filter traps dust, pollen, and other allergens, and the blower distributes the cool air throughout the room.
- Outdoor unit: This unit is installed outside the building and contains the compressor, condenser coil, and expansion coil. The compressor pumps refrigerant gas from the indoor unit to the outdoor unit. The condenser coil releases heat from the refrigerant gas to the outside air. Finally, the expansion coil regulates the refrigerant flow back to the indoor unit.
- Refrigerant: Split air conditioning systems use a refrigerant to cool the air. The most common refrigerant used today is R-410A, which is environmentally friendly and has excellent cooling efficiency.
Split air conditioning systems are popular in homes, offices, and commercial buildings because they are easy to install and maintain. They are also quieter than other types of air conditioning systems, and the indoor unit can be easily concealed with a decorative panel.
Window Air Conditioning
Window air conditioning units are the most commonly used type of air conditioner for single rooms. They are easy to install and are an ideal choice for those who live in small apartments or houses. They are designed to fit in standard-sized windows and require minimal installation time and effort. Window air conditioners are available in a variety of sizes, ranging from 5,000 BTUs (British Thermal Units) to 25,000 BTUs, and they come in different styles and colors to match your room decor.
- Window AC units are cost-effective as they require lesser electricity consumption than central air conditioning units.
- They are ideal for rooms that are not used often, such as a guest room or a workstation.
- Window AC units do not require any ductwork, making them easy to install and maintain.
Window air conditioning units are excellent for single-room cooling and are perfect for those on a tight budget. They are ideal for people who rent or lease their homes, as they can be easily removed and installed in another location. However, these units can be noisy and may not be suitable for larger rooms or spaces. Additionally, they may obstruct the view from your window, restricting the amount of natural light that enters the room.
Despite their limitations, window air conditioners operate efficiently, are easy to use, and are perfect for people who need individual room cooling. They are a great alternative to central air conditioning units, and their compact size and ease of installation make them an attractive option for many homeowners.

-Can be noisy -May obstruct the view from your window -Not suitable for large rooms or spaces |
Cooling Load Calculation
Before choosing any type of air conditioning system, it is important to determine the cooling load required for your space. Cooling load calculation is the process of calculating the amount of cooling required to maintain a comfortable indoor temperature. This calculation takes into account several factors such as:
- The size of the room
- The number of people in the room
- The heat generated by electronic devices in the room
- The number and size of windows in the room
- The level of insulation in the room
- The orientation of the room
By accurately calculating the cooling load, you can choose an air conditioning system that is both efficient and effective for your space. There are two methods for cooling load calculation: Manual J and computer software.
The Manual J method is a manual calculation that takes into account all the factors listed above. This method is more accurate than computer software, but it requires a significant amount of time and expertise. On the other hand, computer software uses advanced algorithms to calculate the cooling load quickly and accurately, but it may not take into account all the factors that can affect the cooling load.
Regardless of the method used, it is important to be as accurate as possible when calculating the cooling load to ensure that your air conditioning system is the right size for your space.
| Factors | Manual J | Computer Software |
|---|---|---|
| Size of the room | X | X |
| Number of people in the room | X | X |
| Heat generated by electronic devices in the room | X | X |
| Number and size of windows in the room | X | X |
| Level of insulation in the room | X | X |
| Orientation of the room | X | X |
Once the cooling load has been calculated, you can choose the type of air conditioning system that is right for your space. Each type of system has different advantages and disadvantages, so it is important to choose the one that best meets your needs.
Energy Efficiency Rating
One of the most important things to consider when buying an air conditioning system is its energy efficiency rating. This rating refers to the amount of energy the system consumes in relation to how much it cools the room or space. The higher the rating, the more efficient the system is, which means it consumes less energy and ultimately saves you money on your electricity bills.
Here are the three types of air conditioning systems based on their energy efficiency rating:

Ultimately, the choice of which type of air conditioning system to purchase depends on your budget, priorities, and the size of your space. Consider consulting with a professional HVAC technician to determine which system is best for you.
Air Filtration Systems
Air filtration systems are an essential part of any air conditioning system. These systems can help to remove impurities, allergens, and other harmful particles from the air, ensuring that the air you breathe is as clean and pure as possible.
There are three primary types of air filtration systems:
- Mechanical filters
- Electronic filters
- UV-C light filters
Mechanical filters work by trapping contaminants in the fibers or porous materials of the filter media. This type of filter is common in residential HVAC systems and portable air purifiers. They can remove larger particles such as dust, pollen, and pet dander, but they may not be effective against smaller particles like bacteria or viruses.
Electronic filters use an electric charge to attract and trap particles as they pass through the filter. These types of filters can be very effective against smaller particles, but they can be expensive to purchase and maintain.
UV-C light filters work by using ultraviolet light to kill bacteria, viruses, and other microbes. These filters are often used in medical facilities and food processing plants to ensure that the air is as clean and sterile as possible.
| Type of Air Filter | Pros | Cons |
|---|---|---|
| Mechanical Filters |

No matter which type of air filtration system you choose, it is important to regularly clean or replace the filters to ensure their effectiveness. Dirty filters can actually make the air quality worse by trapping pollutants and allergens and releasing them back into the air.
Ductless air conditioning units
Ductless air conditioning units, also known as mini-split systems, are becoming increasingly popular in homes and businesses. They are designed to provide air conditioning without the need for ductwork that traditional central air conditioning systems require. Mini-split systems are made up of a small outdoor unit and one or more indoor units that can be mounted on the wall or ceiling. Here are the three types of ductless air conditioning units:
- Single-Zone Ductless Air Conditioning Units: These units consist of one outdoor unit and one indoor unit. They are ideal for cooling one room or area and are relatively easy to install.
- Multi-Zone Ductless Air Conditioning Units: These units consist of one outdoor unit and multiple indoor units, making them ideal for cooling multiple rooms or zones. They are more complex to install than single-zone units but offer greater flexibility and energy efficiency.
- Ducted Ductless Air Conditioning Units: These units are similar to traditional central air conditioning systems but do not require ductwork. Instead, the indoor unit is mounted in the ceiling and is connected to the outdoor unit by refrigerant lines. They are ideal for new construction or renovation projects.
One of the biggest advantages of ductless air conditioning units is their energy efficiency. Traditional central air conditioning systems lose energy through duct leaks, whereas ductless systems deliver air directly to individual rooms, eliminating energy loss. Additionally, ductless systems offer zoning capabilities, allowing you to control the temperature in each room or zone independently. This feature not only increases energy efficiency but also provides greater comfort and convenience.
| Advantages | Disadvantages |
|---|---|
| Energy efficient | Installation can be expensive |
| Zoning capabilities | May not be suitable for larger homes or commercial spaces |
| Flexible installation options | May not be as aesthetically pleasing as traditional central air conditioning systems |
Overall, ductless air conditioning units offer a convenient and energy-efficient solution to traditional central air conditioning systems. They are particularly well-suited to smaller homes and businesses and those looking to increase their energy efficiency and comfort.
