25VNA Infinityt Variable Speed Heat Pump with Greenspeedt Intelligence 2 to 5 Nominal Tons
Carrier’s25VNA with Greenspeedt Intelligenceis abreakthrough product providing up to 13 HSPF heating efficiency and up to 20.5 SEER cooling efficiency. The variable speed capacity control results in strong heating capacity as the outdoor temperature drops resulting in less reliance on auxiliary heat.
Lower speed operation, when needed in cooling, for enhanced comfort and dehumidification. This product has been designed and manufactured to meet Energy Starr criteria for energy efficiency when matched with appropriate coil components. Refer to the combination ratings in the Product Data for system combinations that meet Energy Starr guidelines.
