Condensers
The air conditioning condenser sheds heat from the refrigerant after it leaves the compressor, converting it from a hot gas back into a liquid. It sits in front of the radiator in the airflow.
What it does
High-pressure refrigerant gas passes through the condenser core, where airflow removes heat and the gas condenses to liquid before continuing to the expansion valve and evaporator.
Signs a condenser is failing
- Air conditioning that blows cool rather than cold, worst in slow traffic
- Visible damage or bent fins on the front face
- Oily residue around the core or connections, indicating a refrigerant leak
- High-pressure faults reported during air conditioning diagnosis
When to replace them
Not scheduled. Replaced after impact damage from road debris, corrosion, or a leak. Its exposed position makes it vulnerable.
What to confirm before ordering
Have these ready and the counter can usually confirm the part in under a minute.
- Whether the receiver drier is integrated or separate, since it is replaced with the condenser
- Refrigerant type used by the system
- Core dimensions and connection positions
- Whether the radiator behind it has also been damaged
Condensers by vehicle
Pick your vehicle for the years and engines covered, and what is specific to that application.
Condensers questions
Should the receiver drier be replaced with the condenser?
Yes. Once the system has been opened to atmosphere the drier has absorbed moisture and can no longer protect the system. On many vehicles it is integrated into the condenser anyway.
Why is my air conditioning worse in traffic?
At low speed the condenser depends entirely on the cooling fan for airflow. A blocked or damaged condenser, or a fan that is not running, shows up first in slow traffic and improves once the vehicle is moving.
