Mitsubishi PAA-NL intelli-HEAT service details

The intelli-HEAT™ Dual-fuel system consists of an all-electric heat pump and coil that integrates with an existing gas furnace. This system can provide powerful air conditioning on hot days and determine the best source of heat (gas or electricity) on cold days, maximizing efficiency and comfort. The indoor unit is compatible with both single- and multi-zone outdoor units. A multi-zone outdoor unit can connect to other ducted or ductless indoor units for fixing hot or cold spots or dividing a large zone into smaller, more controlled zones. The PAA also includes a built-in refrigerant leak sensor for added safety.
