Natural loss of gas:
Normally caused by lack of use during cold periods or systems that are not serviced at regular services. Running the air con during the winter months helps with the de-misting process and also keeps the seals moist.
Loss of gas due to leakage:
Pipework and hoses can become loose causing fractures. hoses can rub together causing holes to form. Pipework or condensers corroding with gritting salts during winter. Stone chips to the condenser can cause leaks to start.
Pressure switches, fuses, relays and cables can cause systems to stop running.
A properly functioning air conditioning system makes for a safer more comfortable driving experience. Most probably not so well known is that the air conditioning system in your vehicle is not a fit and forget item. When new your system will work as well as the manufacturer intended, but given time the system can gradually degrade to an unacceptable level.
Air Conditioning is not only for hot muggy days. When used in the colder months it will keep the front screen from misting as de-humidified air is passed over it.
Air Conditioning systems should be "exercised" for at least 10 mins a week to enable oil to reach all seals to prevent them from drying and shrinking and also to lubricate the moving parts of the compressor to avoid costly replacements and repairs.
Is your air conditioning failing to provide its original freshness?
As your car air conditioning system ages, you may notice the freshness of the air provided deteriorating. Whenever your air conditioning is operating, moisture in the air condenses on the system's cold surfaces. Whilst most of this moisture drains harmlessly away, some of the moisture remains within the ventilation system after your A/C has been turned off.
This residual moisture provides the ideal living environment for naturally occurring airborne fungal mico-organisms, mildew and mould.
Recent national media attention has been focused on a new driving phenomenon named 'Sick Car Syndrome' which scientists believe is caused by the build-up of bacteria.
Trapped within the ventilation system, these colonies can combine to produce unpleasant odours and potential flu-like symptoms.
