The Silent Revolution in Air Conditioning

Experience the future of air conditioning with the Cooper&Hunter Concealed Duct Mini Split Systems. These systems are not just an air conditioner, but a complete solution for your heating and cooling needs. As modern architecture moves toward open-concept spaces and minimalist aesthetics, bulky traditional wall-mounted units can sometimes interrupt the visual flow of a room. This is where the concealed duct system shines, offering the power of a mini split with the invisibility of a central air system.

What is a Concealed Duct Mini Split System? A Concealed Duct Mini Split System, also known as a Slim Duct, is a type of Ductless A/C that provides an inconspicuous solution for your cooling and heating needs. Hidden in attics and ceiling crawl spaces, these systems avoid the energy loss associated with traditional large-scale central ducted systems while remaining completely out of sight.

Unmatched Flexibility and Control

One of the key benefits of our Slim Ducts is the flexibility of installation. Unlike standard central air systems that require massive trunk lines and extensive ductwork that can leak up to 30% of their energy, these units use short, focused runs. The ducts can be directed into separate areas which are collectively controlled by one wall thermostat.

For example, one slim duct can be directed to cool and heat hallways, closets, laundry rooms, and bathrooms of a home while the bedrooms themselves are controlled independently. This allows for a "hybrid" approach where common areas are sleek and hidden, while bedrooms might utilize individual wall units for ultra-personalized temperature zones.

Efficiency vs. Design

"Traditional ducted systems lose energy through 'duct leakage' and 'conduction'—meaning you pay for cold air that never reaches your room. Concealed ducts sit closer to the point of use, slashing that waste while keeping your walls clear."

Models and SKU’s: The Right Fit for Every Space

Our Slim Ducts are available in a range of models to suit your specific needs. From a small home office to a sprawling light-commercial warehouse, we have the BTU capacity to match.

03 Why Choose Concealed Ducting?

Quiet Operation: The Library Factor

Because the fan and cooling components are situated inside the ceiling or crawl space—and often wrapped in insulation—the audible noise levels are significantly lower than traditional wall mounts. You won't hear the hum of the unit; you'll only feel the result. This makes them perfect for nurseries, libraries, and conference rooms where silence is non-negotiable.

Improved Air Quality

Our concealed systems feature advanced filtration and high-performance dehumidification modes. By keeping the unit hidden, you also reduce the accumulation of household dust on the unit's exterior, keeping your air cleaner and your maintenance routine simpler.

Significant Energy Savings

Concealed ducts operate on inverter technology. Unlike traditional central air that turns on and off like a light switch, these systems ramp up and down to maintain a constant temperature. This avoids the energy-intensive "startup" phase, leading to massive SEER ratings and lower monthly bills.

See It In Action: Barndominium Showcase

In this featured project, Texas Best Construction demonstrates how the Cooper&Hunter concealed duct system integrates into a modern Glen Rose Barndominium. Notice how the industrial-chic design is preserved because there are no bulky units hanging on the beautiful walls. The cooling is distributed via discreet linear vents that blend into the ceiling, proving that high performance doesn't have to compromise high design.
