ACiQ 4 Ton Inverter Heat Pump – Model ACiQ-48-EHPD Built for large-scale comfort and high efficiency, this 4-ton inverter heat pump delivers 12,000–48,000 BTUs of variable heating and cooling power. With advanced inverter technology, a self-learning condenser, and adaptive sizing, it ensures consistent performance in any climate—from -13°F to 122°F. The two-stage design, R454B refrigerant, and durable gold fin coil make it a powerful, quiet, and eco-friendly solution for ducted systems.
Powerful Inverter Heat Pump Technology: Converts AC power to DC, allowing the variable-speed compressor to adjust output between 12,000 and 48,000 BTU for both heating and cooling—delivering flexible, energy-saving performance all year long.
Smart Learning Condenser: Built-in sensors track duct pressure, indoor/outdoor temperatures, and refrigerant levels. The unit enters a learning mode during initial startup, optimizing future performance for enhanced efficiency.
Adaptive Sizing Performance: Automatically adjusts capacity based on your home's heating or cooling demands. Functions like a smaller system during milder conditions to reduce overcooling and maintain consistent humidity control.
High-Capacity, Energy-Efficient HVAC Solution: Designed for ducted installations, this 4 ton inverter heat pump delivers reliable comfort with significantly reduced energy consumption—ideal for larger homes or light commercial spaces.
Reliable in Extreme Climates: Operates efficiently in harsh conditions, with cooling performance from -13°F to 122°F and heating functionality from -13°F to 75°F.
Eco-Friendly R454B Refrigerant: Utilizes R454B refrigerant with a lower global warming potential (GWP), making it a future-proof, environmentally responsible HVAC choice.
Gold Fin Condenser Coil for Durability: Features corrosion-resistant gold fin coil coating to extend unit lifespan and maintain performance, even in coastal or high-humidity environments.
Quiet Operation: Engineered for silent running—even during full load—perfect for residential applications where noise matters.
Ducted HVAC Compatibility: Seamlessly integrates with existing duct systems, providing a centralized, high-capacity solution for modern comfort control.

I bought this lift for my home garage since I’m always working on cars as a hobby. Installation was straightforward with a buddy’s help. The build quality feels like commercial shop grade.
We’ve had this unit for several months now and it’s been nothing but reliable. It easily lifts our larger SUVs and trucks, and the rolling jack is a nice bonus for versatility.
The safety locks are secure, the platform is stable, and customers are impressed. Easily one of the best investments for my business this year.
If you’re serious about alignment jobs, this is the right tool for the shop.
I run a busy repair shop, and this Katool alignment lift has been a great addition. Smooth operation, reliable locking system, and it saves us tons of time on alignments.
