You drive your Subaru on many outdoor adventures. You know how important a comfortable cabin temperature can be for them. Your original Subaru AC and heating system is the most dependable way to maintain it. How factory HVAC works is easy. Your heater is basically a radiator that sends hot engine coolant through a heater core. A fan passes cooler outside air across the core's fins and into your interior, keeping you warm during your drive. Your air conditioning uses a compressor, condenser, an expansion valve, and an evaporator that work together to cool your cabin. The compressor converts pressurized refrigerant to a hot gas, the condenser chills the gas back to a liquid, and the liquid travels through the expansion valve. It then becomes a low-pressure gas that the evaporator rapidly cools further. This is what chills the air coming through your ducts and out your vents. Eventually, even factory Subaru AC and heating systems can stop working. They can end up with weakened seals, cracked or broken hoses, dead compressors and more. Signs your heating is not working include a steamy cabin, a sweet coolant smell, clogs, and corrosion; they indicate a heater core leak. The main sign your air conditioning is not working is when it isn't cooling properly. That suggests either a leak or low refrigerant levels.
