What are the changes between the 4th and 5th generation DIY?

The 5th generation DIY systems from MRCOOL feature several key improvements over the 4th generation, including:

1. Refrigerant Change: The refrigerant has been upgraded from R410-A to R454-B, which is more environmentally friendly and energy-efficient compared to the previous refrigerant.

2. Performance Enhancements: We’ve made various performance improvements to enhance the efficiency and overall operation of the systems.

3. Expanded DIY Multi Condensers: The DIY Multi condensers now come with additional ports, ranging from 3 to 6, allowing for greater flexibility in multi-zone setups.

4. New Product Offerings: We’ve introduced new 6k BTU air handlers and cassette units to provide more options for different space sizes and installation preferences.

These updates reflect our commitment to providing cutting-edge, easy-to-install HVAC solutions that meet both performance and environmental standards.
