One of these circumstances is in office buildings. Offices can become very hot in the summer which means that staff can get irritable and distracted. The best way to prevent this is to install air conditioning units that will keep everyone cool and fresh. A problem that employers may find however is that they are only renting the office space they are in and therefore aren't allowed to install any units themselves. The perfect solution to this is to hire portable units that don't need any installation. This way everyone can work in a comfortable office and the units can be rented for as long as required.

Even if employers are renting office space and they are allowed to install air conditioning, it is unlikely that they are going to want to because they may only be there for a short period. For example, if the lease is only for two years a company could end up paying a lot of money for the units and installation and then only use it for two summers. In this case it makes a lot more sense to rent units as it will be cheaper and more practical.

British summers can also be very unpredictable which means that a company could end up paying for air conditioning and then not using it for a whole year. However, portable units can be rented out at short notice which means that if it needed they can be hired almost immediately and for as long as required. This saves the expense of installing a system and you know you are only going to paying for something that is definitely going to be used.

Sometimes things such as air conditioning units break which can take time and a lot of money to fix. However, when renting units the company you are renting from will be able to fix them quickly and of they can't they can be replaced. This saves a lot of money and also means that your offices don't have to go weeks without air conditioning until it's repaired.

With so many advantages of renting air conditioning units it's hardly surprising that so many employers are opting to do this rather than have a system installed permanently.
