A common misconception is that air con units are simply used to circulate cold air. However, in commercial premises it’s all about keeping room temperatures ‘just right’ – and heating spaces up when necessary too.
Whether used to cool or keep warm, your AC units play a key role in making sure your guests, residents, customers and staff are comfortable whatever the weather.
A properly planned, located and controlled AC system can keep air temperature consistent, and can even free up areas that might otherwise be unusable – like conservatories or garden rooms which can be too hot to enjoy in summer and too chilly to relax in during the winter.
The latest guidance from CIBSE looks at how HVAC systems can help to reduce the spread of COVID-19, and recommends choosing ‘outside air’ mode where possible. If your air condioning is limited to ‘recirculation’, you may want to consider new appliance options for your building.
‘It is recommended that any ventilation or air conditioning system that normally runs with a recirculation mode should now be set up to run on full outside air where this is possible’.
We’ll take care of it.
There are eight main types of air conditioning equipment out there in the market. Each type of air conditioner is designed for a certain space & fulfills a certain purpose. The different AC types are as follows:
If you have a large home & wish to cool multiple rooms at once then this type of air conditioning is best suited for you. A central air conditioning unit uses a split system that regulates air through ducts installed in your home. It is also known as a ducted system.
The split aspect implies that the system is a combination of two main units. The outdoor unit packs in the condenser and compressor. While the indoor unit comprises the evaporator coils & air handler. Like any typical air conditioner, central air conditioning also uses refrigerant in removing heat from the indoor air. This heat is pulled outdoors & cool air is pushed in through the ducts.
Utilizing modern HVAC technology, programmable thermostats can be coupled with central air conditioners for a smart home experience.

Disadvantages of a central air conditioning system:
If you want better efficiency, or you want to do away with a lot of ducting, or you simply just want a portion of your home to be cooled, then opting for ductless mini-split air conditioners is a great choice.
Such type of an air conditioner is a combination of an outdoor unit comprising of a compressor & a condenser that comes along with one or more indoor units. These indoor units are mounted on a wall and equipped with air blowers. The indoor & outdoor units are connected through tubing and refrigerant circulates through them in variation depending on the type of usage.
Since these indoor units are small and compact, each room usually gets its unit installed that can either be used for heating or cooling purposes. Such types of air conditioners are regarded much more efficient in energy consumption compared to some of the other options available out there but can also be heavy on the pocket if you plan on installing one in each room to cover the entire house.
Ductless mini-splits come with a remote control but coupled with a smart AC controller you can operate them using your phone, from anywhere!

Since Window air conditioners come in different sizes, they would be suitable if you’re looking to cool a single room or a small area. If you go for a large window air conditioner you can even cool a small home considering it is a single story or one open space. Window air conditioners, since the beginning, have been labeled as champions of cooling smaller spaces & regarded as the most common type of air conditioner.
A window air conditioner is a single unit with all of its components enclosed inside. It ejects heat out of its outdoor side and blows cool air into the room on the indoor side. As the name suggests, it is installed in a window or by making a hole in the wall. Such air conditioners have a filter that slides out so that it can be cleaned regularly for full AC efficiency. These air conditioners have controls on the unit & may also come with a remote.

Disadvantages of Window ACs:
Portable air conditioners are similar to window air conditioners. They are also placed in a single unit with all its components enclosed inside but the difference is that it is a free-standing unit and therefore can be moved from room to room. All it requires is a power outlet to power it up & access to a window where the unit’s air can be exhausted from using its funnel.
You can opt for a portable air conditioner if you want temporary space cooling or wherever it’s not practical to install a window or split air conditioner. They are very handy and smaller versions can even be used for kennels or bathrooms. Portable ACs can be singl- hose that takes in air from inside a room and expel it outdoors. Or, dual-hose which pulls air from the outdoors using one hose, this air cools the compressor and is then exhausted outdoors from the other hose.
Since a portable unit sits indoors, its evaporator fan runs continuously to evaporate the condensed moisture that is collected inside the unit.
Advantages of portable ACs are:
Disadvantages of portable ACs are:
Floor mounted air conditioners are designed for convenience if you prefer a mini-split but lack the required space for a wall mounted unit. The indoor unit of floor-mounted AC rests on the floor, and the outer unit can be installed without major site preparation or any ductwork. This arrangement is also ideal for spaces with tilted walls such as attics or building constructed by fragile materials such as glass.
The unit can be installed up to 6 inches higher than the floor, and through a small hole in the wall it is connected to the outdoor unit.
An amazing benefit of the placement of this AC is that it allows you to very easily check the air filters!
Easy access to the air filters makes floor-mounted air conditioners ideal for individuals with respiratory issues or people who are keen on keeping their indoor air quality as clean as possible.
Floor mounted systems cool/heat the room quicker than any other mounting system as the fan blows the air directly at your level. On the contrary, units that are mounted high up on the wall can often face difficulties cooling the room uniformly and efficiently. Floor units need free space around them though to function efficiently and circulate the air adequately. Make sure the unit is not obstructed by furniture or walls.
Advantages of floor mounted ACs:
• Perfect for elderly people living in the house due to accessibility
• Can be installed easily
• An excellent choice for difficult and small areas as they do not take much space
Disadvantages of floor mounted air conditioners:
• Airflow can be compromised because of the obstacles in the room, i.e., furniture
• Not suitable for big rooms due to uneven and localized distribution of airflow
Smart air conditioners are a type of mini-split, window or portable air conditioner that are IoT enabled. These ACs are connected to the Wi-Fi and come with a native app providing global control through a smartphone.
Depending on the manufacturer, these air conditioners come with numerous functionalities. Some of these include weekly scheduling, geofencing, comfy mode, temperature range control, and numerous other features. Utilizing these, you can achieve great comfort coupled with energy savings.
Smart AC controllers are also available in the market that provides all the functionalities of a smart AC to any conventional ducted unit. They work like programmable thermostats and come at a fraction of the cost compared to smart ACs.

Geothermal heating & cooling is considered a relatively new method, it works by utilizing the insulating properties of the earth. Since the temperatures under 4 to 6 feet of land remain consistent all year regardless of the weather, geothermal technology takes advantage of this to heat & cool your home more efficiently.
This system has piping that consists of a loop that circulates water between your home, a heat pump & the ground. They require intensive work to set up underground.

Disadvantages of a geothermal AC system:
A hybrid system is one that combines a gas furnace with an electric air-source heat pump to deliver a cost-effective & efficient performance in terms of heating & cooling. Depending on the temperature outdoors, the system automatically switches between burning fossil fuels and the usage of electricity. You program the temperature at which the system switches from heat pump to furnace or you can make the manual switch too.
During the summer season, the heat pump works as it is functioned to, pulling hot air from inside your home and throwing it outdoors. During the winters, this process is reversed and heat is distributed throughout your home. When the temperature is too cold for a heat pump to function efficiently, the furnace kicks in.
