Common Problems With Car Air Conditioning

Common Problems with Car Air Conditioning

The air conditioning system plays an important role towards passenger comfort whilst in the vehicle, helping us to stay cool on hot summer days; this is something especially important when travelling at high speed or in heavy traffic, when opening the windows is an unpleasant option. The air conditioning is also frequently utilised on damp, chilly winter days to demist the windscreen. Despite its important function, many of us do not give the air conditioning a second thought until something goes wrong.

There are a number of potential reasons that could cause the air conditioning system to fail, however, with regular maintenance, servicing and re-gassing, these problems can be identified before they cause further damage.

Common Problems

Air Conditioning Re-Gas

When the air conditioning is switched on and the air that blows out is not as cold as it used to be, or it doesn’t seem to make any difference, this is often a sign that the air conditioning needs re-gassing or recharging. This refers to the process of removing the old refrigerant gas and replacing it with a new refrigerant to ensure that the air conditioning is functioning properly and blowing out cold air. Over time most cars will need re-gassing or recharging; this is a relatively straight forward process which can be performed at your local garage. Most manufacturer’s guidelines recommend a re-gas every two years, although some people prefer to wait until the air conditioning is no longer blowing cold air.

System Leaks

A leak in the air conditioning system is more complex than a simple re-gas - it can be more difficult to pinpoint the exact location of a leak in the air conditioning system, but it is often a result of a worn valve or seal. One of the most common places to find a leak is at the unit hose connection – although a leak can occur at any place throughout the unit. The sooner a leak is identified, the cheaper the repair is likely to be. The longer the leak is left unrepaired, the greater the chances are that moisture will work its way into the air conditioning system, causing more serious problems. Leaks are generally caused by wear and tear, age, and moisture. Over time, the seals and hoses lose their strength and elasticity, causing them to break down and allow moisture to enter the air conditioning system.

Compression Issues

The compressor is a key part of the air conditioning system – it compresses the refrigerant gas. If the compressor is not working, then the air cannot get cold.

The Condenser

A clogged or damaged condenser will not allow the refrigerant to flow, if this happens, the air conditioning will be unable to blow cold air.

Electrical Fault

Many of the components of the air conditioning system are electrical and something as simple as a blown fuse can cause the whole system to stop working.
