If you go on frequent road trips, you may experience various weather conditions. Whether it's winter or summer, your Subaru vehicle's HVAC system will heat, cool, and ventilate your cabin.

How Do HVAC Systems Work?

If you're wondering how a car HVAC system works, you're not alone. The heating system works like a radiator. It pulls coolant from your engine into a small heater core, and a fan blows cool air from outside over the core's fins.

The air conditioning system is more complex since it uses more parts. First, the compressor pressurizes the refrigerant and alters it to hot gas. Then, the condenser cools the gas and turns it to a liquid. The liquid passes through the expansion valve and turns into gas, and the evaporator cools the gas down with a fan. This process keeps you and your passengers comfortable as you drive in hot climates.
