Vehicle Air Conditioning Frequently Ask Questions.

Like any other part of your car, in order to run efficiently the air-conditioning system needs regular attention.

In fact, it needs periodically recharging with gas and lubricant in order to avoid unpleasant smells and harmful bacteria forming.

What’s more, an air-conditioning system that does not have the correct level of gas has to work harder, in turn putting strain on the engine and subsequently using more fuel.

Motocolor (Southampton) Ltd are the experts when it comes to vehicle air conditioning.

Frequently Ask Questions:

How often should my air conditioning system be serviced?
Every 2 years to ensure it operates at maximum efficiency. If you let the system run low on refrigerant the compressor has to work twice as hard and will therefore wear out in half the time. Air conditioning is not normally serviced with your annual car service.

How often should I run the air conditioning in my car?
All the time on hot or cold depending on the outside temperature. This will ensure that the rubber seals and gaskets in your system don't dry out and crack, thereby causing leaks. Run your system for a few minutes every week at the very least. Contrary to popular belief, it does not greatly reduce your mpg, the drag created by having a window open can reduce your mpg more than running the air conditioning.

When I switch on my air conditioning I get a smelly 'pong' inside the car, what causes it and how do I get rid of it?
It's micro-organisms that collect on the evaporator behind the dashboard and the fan blows these nasties into your face causing allergic reactions, coughs, sneezes and sore throats. We can treat your air conditioning system and kill them off.

Why does my car air conditioning system run low on refrigerant?
All the pipes and connections on your air conditioning system are naturally slightly porous, so you lose anything up to 20% of the gas every year due to natural leakage.

If the gas leaks into the passenger compartment of my car, can it be dangerous?
No, the modern refrigerant called R134a, is not harmful to health and is not an explosive gas. It is also environmentally friendly unlike the old refrigerant gas R12 which was phased out from 1993.

What is included in the air conditioning service?
The following items:
     -Recovery of refrigerant
     -Evacuation of air and moisture from the system
     -Vacuum leak test
     -Recharging to recommended levels, adding fresh system oil
     -Air-conditioning cleaner to clear bacterial build up and remove
      any unpleasant smells

We also service air conditioning in light commercial vehicles up to 3.5 tonne.
