Still want to use the ductwork in your home but want the efficiency of a mini split? ACiQ’s next gen heat pumps are designed to operate at up to 20 SEER, much higher than most state minimum 14 SEER systems. While most central heat pumps only function down to 35F, all ACiQ next gen heat pumps can heat down to at least -4F, keeping the efficiency granted to you by using ACiQ’s technology. Need it to heat lower? No problem: each air handler can handle a backup heater coil to heat down to any temperature as straight electric heating.
