ML14KP1 Heat Pump
Fantastic Product
April 24, 2025Our highest energy usage day after installation is still lower than the lowest energy usage day before installation. The difference is noticeable and with the new refrigerant, I feel future-proofed for years to come. 10/10.

Yes, I recommend this product.
