Dear Customers, Welcome to the launch of our new website — formerly known as MRCOOL ONLINE! We’re currently updating our product catalog to include the 5th Generation DIY Multi-Zone and Single-Zone mini-split systems. In addition, we’ll soon be offering the Versa Pro line of central heating and cooling systems, a value-based option ideal for more moderate climates such as the Southwest Coastal region of Canada. Please note that MRCOOL is transitioning its inventory to the new R-454B refrigerant, and systems featuring this refrigerant will be available to ship in the coming months. Thank you for visiting Horizonsun Heat Pumps. We hope you enjoy a smooth and pleasant online shopping experience. Warm regards, The Horizonsun Heat Pumps Team Dismiss
