Your vehicle’s AC system compresses and heats the refrigerant, then allowing it to decompress and condense into a liquid that causes it to rapidly lose heat. This process absorbs heat from the car’s cabin and is continuously repeated to achieve your desired temperature.

There are a variety of reasons why your car AC is not blowing cold air. Fixing the AC could be as simple as recharging your car’s AC refrigerant or repairing a refrigerant leak but may also require complex electrical climate control repair or slipping compressor clutch to get your air conditioning operating at top performance once again.

Trusted professionals at any one of our Unipartner approved garages can help diagnose your car AC issue.

Here are the top 3 reasons why your car may not be blowing cold air:

1. Your AC Refrigerant Needs a Recharge

The most common cause of a vehicle’s air conditioner not getting cold enough is that it needs to be recharged. You can recharge your refrigerant by yourself, but to save time and make sure the job is done correctly you should make an appointment with a Unipartner garage.

2. An AC System Refrigerant Leak

When your vehicle’s AC system develops a refrigerant fluid leak it can be challenging to detect due to the fact that refrigerant fluid instantly evaporates when it comes in contact with air. A professional mechanic uses specialized tools to determine if there is a leak by introducing ultraviolet fluid to show signs of low refrigerant pressure in the AC system. Signs of an AC system refrigerant leak:

• Audible click when the AC is turned on.
• AC cycles on and off frequently.
• Hissing sounds from the AC system (when the engine is off).
• Oil residue around AC pipe fittings and hoses.

A refrigerant leak repair may include repairing or replacing the specific failing component. If a large amount of fluid has been lost, your AC system will need to be flushed and the refrigerant fluid will need to be replaced to function properly and get the cool air flowing. *Please note that refrigerant is a very harmful toxic chemical and should not be handled without the proper equipment operated by a trained Unipart Car Care Centre or Bosch Car Service professional.

3. Fan Motor Failure

Another common source of trouble in your car’s AC system might be the fan(s) motor located at the front of the vehicle’s motor. Whether your car has one or two fans, it is important that the fan is in good working order to both keep you cool and to provide vital cooling to your engine.
