Some of your questions about air conditioning answered.
Generally speaking, it is prohibited to deface a Listed building, which can include making penetrations through walls or fixing outside AC units to areas seen by the general public or others. Conservation areas are also subject to similar restrictions as the general look of the area is protected. An alternative option to consider is installing a water cooled air conditioning systems.

It depends on the property location. If the outdoor unit is either intrusive to the eye or noise can be heard from the unit which is higher than the maximum allowable decibel reading as per the local council’s legislative requirement, or if the unit is in a Conservation area then yes. Otherwise no it is not a requirement.
A typical single split type AC unit will take 1-2 days to install.
The benefits of air conditioning are many. Not only can it provide a natural source of dehumidification when cooling in the summer, but it is also a much cheaper way of heating your premises during the winter. Conventional electric heating or gas fired boilers with radiators is considerably more expensive compared to the cost of running a heat-pump AC unit on heating mode.
Modern units are very quiet. In the workplace, you rarely notice them while in bedrooms at night time certain specific night set back settings slow the fans down to reduce the cooling requirement in line with falling ambient temperatures.
Air conditioning works by way of transferring heat from the air inside a room into the internal gas and then pumped along the pipework to an outdoor unit where the gas transfers the heat to the external air. The heat exchange process happens when the internal air is passed over a heat exchanger coil called an evaporator. Inside this evaporator is refrigerant that boils off at a very low temperature making the coil very cold. When the warm air passes over it then heat is absorbed from the air into the coil. The reverse happens with the heat exchanger in the outdoor unit.
Generally, if it’s in a home then at least once a year. If in an office at least twice a year and if in a comms room, then 4 times a year. However, it really does depend on the environment. For example, a shop which is open to the walk-in traffic of the street may need more visits.
A single AC unit of average size will run at a similar cost to a domestic fridge as modern technology allows the power element of the unit to speed up and slow down according to the demand.
There are many reasons why your AC unit might not be working but the main one is lack of maintenance. Most AC units have a diagnostic facility that tells the user there is a fault. It can be a code on a controller display or a series of flashing lights on the unit.
