Subaru Subaru Impreza 2011-2016 HVAC Specifications

The HVAC system is compatible with all 2011-2016 Subaru Impreza models, including sedan and hatchback variants. It supports both manual and automatic climate control systems. However, specific components like the blower motor or condenser may vary slightly depending on the trim level and optional features. Always verify part numbers with your vehicle's VIN to ensure compatibility.

Regular maintenance for the HVAC system includes replacing the cabin air filter every 12,000-15,000 miles, inspecting refrigerant levels annually, and checking for leaks in the system. The compressor and blower motor should be inspected every 30,000 miles. Ensure the condenser and evaporator are clean and free of debris to maintain optimal performance.

To replace the cabin air filter, locate the filter housing behind the glove compartment. Open the glove box, remove the retaining clips, and gently lower the glove box. Unclip the filter housing cover, remove the old filter, and insert the new one, ensuring it faces the correct direction. Reassemble the glove box and clips. This process takes about 10-15 minutes.

If the HVAC system is not blowing cold air, first check the refrigerant levels and look for leaks. Inspect the compressor and ensure it is engaging when the AC is turned on. Clean the condenser and evaporator coils, and verify the blower motor is functioning properly. If issues persist, consult a professional for further diagnostics.

To optimize HVAC performance, regularly clean or replace the cabin air filter, ensure refrigerant levels are correct, and keep the condenser and evaporator free of debris. Use the recirculation mode in hot weather to reduce strain on the system. Park in shaded areas to minimize heat buildup, and have the system inspected annually by a professional.
