Car Air Conditioning Service

A car air conditioning system that blows out stuffy, hot air on a stifling summer’s day is enough to drive anyone mad. If this sounds familiar, it's highly possible that your car aircon system is low on refrigerant, most likely because there is a leak. On more modern vehicles, if the refrigerant reaches a critically low level, they are designed to automatically shut down in order to protect the air conditioning compressor.

We can test the complete system by performing an air con recharge using our gas recharge system. We recharge your car air-conditioning with the required level of refrigerant as recommended by the vehicle manufacturer.

How Often Should I Recharge My Car Air Conditioning?

Although the air conditioning in your car is a closed system, approximately 10% of air conditioning gas permeates from your car aircon system every year. Therefore, car manufacturers recommend your car air conditioning system is recharged with refrigerant gas and lubricant every two years. This service is not part of routine mechanical servicing, so if your vehicle is more than two years old, it’s probably due an air con recharge to regain its efficiency.

How Does Car Air Conditioning Work?

As it says on the tin, car air conditioning simply ‘conditions’ the air. This means that it cools down the air in your car, whilst also reducing levels of moisture and humidity. To get scientific, this occurs through processes of evaporation, condensation, compression and expansion. 
There are three key main components which make up your car aircon system: 
The compressor compresses the refrigerant gas and pushes it out to the condenser.
The condenser creates heat; however, the air flow cools the refrigerant down and causes it to regain its original liquid form.
The evaporator transforms the cool refrigerant liquid into a gas again, which then moves out. Fans blowing over the evaporator cool the air down as it enters the vehicle.

Top Tips for Making the Most of your Aircon:

• In hot weather conditions, switch your air con/climate control to recirculate mode to block the hot air entering the car and recirculate the cool air to be more effective.  

• Don't wait for your car air conditioning to cool down before you drive off. Your aircon works more effectively when you are driving. This is because the compressor will run faster if the engine turns faster.

• Ensuring your car aircon is set to the lowest temperature and adjusting the fan as desired will mean that you can save on fuel.
