The condenser is the exterior half of an HVAC central split system. Every condenser houses two critical components: the compressor and the condenser coil. Similar to an organic heart, the compressor is responsible for pumping the refrigerant through the coils. The better the compressor, the more efficient the whole system will operate. The condenser coil is, like the evaporator coil, a conduit for refrigerant. Depending on the system particulars, the condenser coil will either collect or release heat into the outside air.
