FAQ'S

Which Peterbilt models do your condensers support?
Our condensers are engineered to match OEM core dimensions, port locations, and mounting configurations for a wide range of Peterbilt models—such as the 579, 389, 567, and 389 series—ensuring a precise, drop-in replacement.

What is the function of a condenser in a heavy-duty truck’s AC system?
The condenser transforms the hot refrigerant vapor exiting the compressor into liquid by dissipating heat to ambient air. This step is necessary for delivering cooled air to the cab and completing the refrigeration cycle.

How do I choose the right condenser for my Peterbilt truck?
Compare the core’s physical dimensions, inlet/outlet offset and size, number of rows, and mount points. Matching those parameters or confirming with the OEM part number ensures compatibility and optimal performance.

Can I replace only the condenser without replacing other AC system parts?
Yes — if the rest of your AC components (compressor, evaporator, hoses, etc.) are in good working order. However, many technicians recommend replacing related parts such as the receiver/drier or expansion device at the same time to ensure system longevity.

What symptoms might indicate a failing Peterbilt condenser?
Common warning signs include reduced cooling efficiency, warm air blowing through vents, visible refrigerant leaks, clogged or bent fins, or elevated under-hood heat. Timely replacement helps restore AC performance and prevent further system damage.
