All Seasons Heating & Cooling is a licensed dealer for Carrier heat pump systems. Allowing for the ability to move heat from one location to another, heat pumps can also work in a cooling mode that will offer the same benefits as a traditional air conditioner. We offer Carrier heat pump systems with various efficiency ratings and sizes that will certainly meet your needs.

Infinity Variable Speed Heat Pump with Greenspeed Intelligence

Carrier’s 25VNA with Greenspeed Intelligence is a breakthrough 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.
