Air-Con ATUCI4H1S12 / ATUEM4H1S12 12,000 BTU Ductless Mini Split Heat Pump System
Efficient, All-Season Heating and Cooling for Small to Mid-Sized Spaces
The Air-Con ATUCI4H1S12 (indoor unit) and ATUEM4H1S12 (outdoor unit) form a compact yet powerful single-zone ductless mini split heat pump system, designed to provide precision comfort in rooms up to 600 square feet. This system is a perfect fit for homes and small businesses across the U.S., including regions with variable seasonal temperatures like the Midwest, Northeast, or mountain towns. Its versatile application makes it ideal for bonus rooms, finished basements, sunrooms, garages, or ADUs where central HVAC may be impractical or overkill. With 12,000 BTU cooling capacity and 13,000 BTU heating output, it delivers reliable climate control tailored to specific zones—helping users save energy and reduce utility bills. Whether you're in humid summers of Florida or chilly winter zones like Colorado or Minnesota, this unit keeps indoor temperatures stable without compromise. The slim indoor head unit installs easily on most interior walls, while the compact outdoor condenser requires minimal space and meets most HOA noise level guidelines. This ductless heat pump offers the flexibility and energy-conscious performance modern homeowners and contractors are searching for.
Smart Inverter Technology Meets High SEER Performance
Built with advanced DC inverter compressor technology, this system continuously adjusts its output to match the exact heating or cooling demand of your space. That means it avoids the energy spikes associated with traditional on/off systems, reducing wear on the compressor and delivering smoother, more consistent comfort. Rated at 18 SEER and 10 EER, it meets and exceeds energy efficiency standards required for many regional rebates and ENERGY STAR-qualified incentives. This makes it a great option for customers looking to meet local energy codes or green building requirements, especially in states like California, New York, or Washington. Inverter-driven performance also contributes to quieter operation, with indoor sound levels as low as 33 dB(A)—ideal for bedrooms, nurseries, or work-from-home setups. By using only the power needed to maintain target temperatures, the system helps reduce both electricity use and carbon footprint, a growing concern in today's environmentally conscious market. Whether cooling in Phoenix or heating in Anchorage, the technology ensures reliable, efficient comfort in any climate.
Titanium Series Reliability in Extreme Weather Conditions
Part of the high-efficiency Titanium Series from Air-Con, this mini split system is engineered to perform in even the harshest outdoor environments. The unit operates in ambient temperatures as low as -4°F in heating mode and 5°F in cooling, making it a strong fit for cold-weather states like Michigan, Pennsylvania, or upstate New York. Unlike standard HVAC units that require additional heating sources below freezing, this system maintains strong performance in winter without supplemental heat. For southern climates, it handles high summer heat with ease while providing year-round dehumidification, which is especially beneficial in humid zones like Georgia or the Gulf Coast. Its whisper-quiet indoor operation and minimal vibration make it HOA-friendly and ideal for urban multi-family settings or noise-sensitive neighborhoods. Despite its compact footprint, it delivers robust and reliable comfort without the need for bulky ductwork or expensive retrofits. From high-altitude homes in Colorado to humid coastal rentals in South Carolina, this unit adapts to your space and season.
