Your Subaru is equipped to safely handle all types of weather. That includes your factory AC system, which is responsible for maintaining a comfortable cabin temperature no matter how hot or cold it gets outside. The process isn't complicated at all.
The air conditioner relies on a compressor, condenser and evaporator. Pressurized refrigerant is converted into a hot gas, get chilled to the point that it becomes a liquid, and then gets sent through a valve where it becomes a low-pressure gas. After that, it gets chilled one more time. That gas is then sent through your air vents to cool your passenger space.
Heating is even simpler. Hot coolant is drawn from the engine into a heater core. A front mount fan blows outside air over the core fins, releasing the warmer air through your air vents and into the cabin.
How to Spot AC System Troubles
Even the best HVAC components can fail over time. Signs of that include:
- A steamy cabin environment
- Worn-out belts and hoses
- The sweet smell of coolant
- Your system stops blowing cold or hot air
If you experience any of these, check your cabin air filter first. If it looks to be in good condition, the problem likely lies within your AC system. When you do need to replace an AC system part, make sure to choose the right one for your model.
