Through-the-wall air conditioners with heat pump

Step into a new era of home comfort with our collection of through-the-wall air conditioners with heat pump. These refined systems are purpose-built for quiet operation, low energy consumption, and all-season performance. With no need for an outdoor condenser, they offer a discreet and elegant way to heat and cool your space — an ideal choice for stylish homes, apartments, and professional interiors.

What Exactly Is a Through-the-Wall Air Conditioner with Heat Pump?

A through-wall air conditioner is a single-unit system that fits directly into an exterior wall, removing the need for bulky external equipment. Inside one compact housing, it integrates an inverter compressor, advanced filters, and an intelligent heat pump that efficiently switches between cooling and heating modes. This allows for stable indoor temperatures year-round, without the complexity of traditional split systems.

The design is sleek and minimalist, making it perfect for spaces where aesthetics matter just as much as performance. A through-wall AC gives you comfort and control with minimum visual impact and almost no installation hassle.

Quiet, Smart, and Exceptionally Efficient

Our quiet through wall air conditioner range delivers outstanding acoustic comfort thanks to multi-speed fans, soundproof insulation, and adaptive inverter technology. Even at high output, they run softly — you’ll feel the difference in temperature, not hear it. It’s the ideal solution for bedrooms, studies, and open-plan living areas where peace and comfort go hand in hand.

Unlike temporary or portable air conditioners, these permanent systems blend seamlessly into your walls, preserving interior design harmony and keeping cables, vents, and outdoor components out of sight.

Combined with heat pump functionality and the eco-friendly R32 refrigerant, these systems provide outstanding environmental efficiency with lower carbon emissions.

Most models also include built-in Wi-Fi control, allowing you to adjust temperature, mode, and timer settings via smartphone. Whether you’re on your sofa or on the go, your perfect climate is always just a tap away.
