Which HVAC component is responsible for increasing refrigerant pressure in the system?

Explanation:
The compressor does. In the vapor-compression refrigeration cycle, it takes the low‑pressure, low‑temperature vapor from the evaporator and compresses it into a high‑pressure, high‑temperature gas. That high-pressure gas then moves on to the condenser where it releases heat and becomes a liquid. The other components have different roles: the condenser rejects heat and condenses the gas, the expansion device drops the pressure before the liquid returns to the evaporator, and the evaporator operates at low pressure to absorb heat.
