AC Condenser vs. AC Compressor: Know the Difference

By Hifza Nasir & Shumaila Saeed || Published on March 1, 2024

AC condensers release heat from refrigerant into the air, while AC compressors pressurize refrigerant to keep the cooling cycle moving.

Key Differences

The AC condenser plays a crucial role in dissipating heat absorbed from inside your space by releasing it outside. In contrast, the AC compressor's job is to pressurize and circulate refrigerant, enabling it to absorb heat efficiently.

Refrigerant arrives at the condenser in a high-pressure vapor form. Here, it condenses into a liquid by cooling down. The compressor, meanwhile, takes this liquid refrigerant, compresses it into a high-pressure vapor, and sends it back to the condenser.

The efficiency of your AC system heavily relies on the proper functioning of both the condenser and the compressor. A malfunction in either component can significantly reduce cooling effectiveness.

Condensers are typically located in the outdoor unit of split-system air conditioners, alongside the compressor. This design helps in the efficient expulsion of heat to the outdoors.
