ACiQ 4 Ton 15.5 SEER High Efficiency Central Air Conditioner Condenser - R410A Inverter
Overview
Inverter Technology - Inverter technology converts AC power to DC, allowing the compressor inside your condenser to speed up and slow down. This enables the system to automatically self-adjust BTU output based on demand, ensuring optimal cooling performance as the weather changes.
Learning Condenser - Equipped with advanced sensors, this condenser monitors air temperature inside and outside, overall system performance, duct pressure, and refrigerant temperature. During the initial startup, it enters a learning mode to optimize efficiency for future operation by continuously gathering and storing critical data so future startups and run cycles will be at max efficiency.
Optimized Cooling - The self-adjusting inverter design allows the condenser to operate all the way down to a 1 ton unit when needed, keeping you cool and comfortable, making it an ideal seasonal device for hot climates where additional air conditioning is needed for homes already heated by boilers, fireplaces, or other sources of heat. For optimal performance, pair the ACiQ-48-AC unit with the ACiQ-48-ACL coil.
Product Features:
- Well-suited for medium to large homes in various climates
- High efficiency inverter condenser
