Revolutionize Your Defender:
Advanced Air Conditioning & Heating in One

Your Land Rover Defender is built for adventure, but that doesn't mean comfort should take a back seat. Installing a high-performance air conditioning system isn't just about staying cool in the summer; it's about ensuring a healthier, more enjoyable, and climate-controlled driving environment for you and your passengers all year round.

Traditional AC setups in Defenders rely on separate cooling and heating units, leading to inconsistent airflow. Dry, cooled air from the AC clashes with moist, heated air from the separate heater box, causing screen fogging and a damp cabin. Our integrated AC/heater system solves this problem by using dual-core technology, just like modern climate control systems.

Why Upgrade?

✔   All-in-One Climate Control - Enjoy powerful cooling and heating from a single unit.

✔   Dehumidified Airflow - No more misted windows or damp interiors, even in winter.

✔   Stronger Heating & Ventilation - A three-speed blower ensures efficient air circulation.

✔   No Compromise on Space - Fully integrated design means no lost legroom.

✔   Unbeatable Value - Get superior heating and AC at a lower cost than traditional systems.

Designed to work seamlessly with our Puma Dashboard™ upgrade, our 319 AC/Heater system can also be retrofitted to any Defender up to 2006. Professional installation is required, but the results speak for themselves. Unparalleled comfort and performance in your Defender, no matter the season.
