CANAIR 4CDH \u2013 HIGH-EFFICIENCY CENTRAL HEAT PUMP FOR QUEBEC<\/strong><\/h3>\n

The Canair 4CDH side-discharge central heat pump<\/strong> is designed to provide powerful and stable comfort in Quebec\u2019s challenging climate. Capable of operating down to -30\u00b0C<\/strong>, it delivers reliable heating in winter and efficient cooling during hot summers.<\/p>\n

This system uses R454B refrigerant<\/strong>, a next-generation, low-GWP refrigerant that reduces environmental impact while maintaining high efficiency and reliable performance.<\/p>\n

Thanks to Inverter Technology<\/strong>, the system continuously adjusts its capacity instead of turning on and off, improving temperature stability, reducing noise, and lowering energy consumption. With performance reaching 19 SEER2<\/strong> and 10.3 HSPF2<\/strong>, the 4CDH perfectly meets the needs of homeowners seeking efficiency, durability, and year-round comfort.<\/p>\n
