Scientists have agreed that the temperature and humidity at the workplace has a direct impact on the productivity of employees.
If the room is too hot, employees are more likely to feel sleepy and their concentration level drops dramatically. On the other hand, very low temperature leads to illnesses and complaints. In order to keep your employees awake and focused longer, the room should be cooled to the temperature around 20 or 21 degrees. 
However, not every air conditioner meets the basic requirements and may be unsuitable for the office with regards to the size or functions. As employers are responsible for the health of their staff, it is important for them to choose the air conditioning carefully.
As we specialise in air conditioning maintenance and portable air conditioning, here are some valuable tips on how to choose the right air conditioner for your office.
Type
Portable, fitted, cooler, fan; there are many types you can pick from. The important thing you need to consider is how, where and for how long you want to use it. If you need a temporary cooling system, you can just hire one for a limited period and save money.
Size
Contrary to the common belief, bigger is not necessarily better. Oversized air conditioning unit may consume more energy than it actually needs, which will reflect on your next bill. Nevertheless, if the unit is too small it will not be able to cool the room properly. The best thing to do is to seek an advice of a specialist.
Maintenance
A lot of people neglect the maintenance and thus considerably shorten the air conditioning’s lifespan, not talking about increasing its consumption of energy. Professional maintenance not only saves you money but also makes sure the unit works well for longer period of time.
