Not so many years ago, air conditioning was a luxury
vouchsafed only to the privileged few; now, though, it's the
norm in many offices and public transport systems, so it's a
part of our lives whether we want it or not. Unfortunately,
abusively low temperatures and faulty maintenance have
led to health problems, triggering common disorders in some
people and occasional major outbreaks of illnesses such as
Legionnaires' disease.

respiratory system.
It has a drying effect on skin and mucous membranes.
It adds to ambient noise, contributing to noise pollution.
The air circulation can transmit infectious respiratory
diseases.
Airborne dust and fungi can cause allergic reactions.
Air conditioning is associated with chronic rhinitis and
pharyngitis, throat irritation and hoarseness.
Air conditioning can exaccerbate eye conditions such as
conjunctivitis and blepharitis, as well as causing problems
for contact lens wearers.

Professional installation and maintenance is essential for
both individual units and centralised systems.
