Explore our collection to find the right match for your cooling needs.

How Does Central Cooling Systems Work?

A central air system relies on paired indoor and outdoor units connected by refrigerant lines. When your thermostat senses heat indoors, it signals the air conditioner to begin. The outdoor unit’s compressor pressurizes refrigerant, then the condenser transfers the captured heat to the outside air. That cooled refrigerant flows through the lineset into the indoor unit, where the evaporator coil absorbs warm air from inside and blows chilled air back through your ductwork. This cycle repeats to maintain a steady temperature. Properly sizing avoids an oversized unit, which can short-cycle, ensuring consistent, efficient cooling on the hottest days.

Components of a Central Cooling Air conditioning System

Central cooling air conditioning systems consist of several key components that work together to provide effective cooling. These components are carefully designed to maximize efficiency and ensure reliable performance. The condenser, compressor, lineset, evaporator, and expansion valve all play crucial roles in the cooling process, each contributing to the system's overall functionality. By understanding how these components work, you can better appreciate the technology behind central cooling systems and how they keep your indoor environment comfortable. At HeatAndCool.com, we offer a range of central cooling systems with these components, ensuring that your home or office stays cool and comfortable throughout the year.

Condenser

The outdoor unit’s condenser releases heat absorbed from inside. It moves refrigerant through a series of fins and coils, using the fan to expel high outdoor temperatures.

Compressor

Located in the outdoor unit, the compressor pressurizes refrigerant, raising its temperature so it can circulate effectively. This is critical for the HVAC system to achieve both heating and cooling modes.

Lineset

Insulated copper piping links indoor and outdoor units. The lineset safeguards refrigerant temperature as it travels, enabling optimal performance.

Evaporator

Housed in the indoor unit, the evaporator coil absorbs warmth from indoor air. As refrigerant expands through the coil, it changes state and cools air before returning it to your living space.

Expansion valve

This valve meters refrigerant into the evaporator at the correct pressure. It ensures the air conditioner operates efficiently and prevents liquid refrigerant from damaging the compressor.
