Advanced Invisible HVAC Solutions

Concealed duct systems are the "gold standard" for high-end renovations. Unlike wall units, they allow you to place multiple supply vents in one room for perfectly even airflow without hot or cold spots.

  • ✓
    Static Pressure Control: Adjustable fans allow for short duct runs to deliver air precisely where it's needed, even behind decorative grilles.
  • ✓
    Fresh Air Connection: Most Slim Duct models feature a knock-out for fresh air intake, improving indoor air quality beyond standard filtration.
  • ✓
    Built-in Condensate Pump: Every unit includes a powerful internal lift pump, making ceiling installation hassle-free even in tight spots.
  • ✓
    Discreet Serviceability: Requires only a small access panel for maintenance, keeping the aesthetic of your ceiling clean and professional.
  • ✓
    Inverter Technology: Features premium brands like Cooper & Hunter with inverter-driven compressors for maximum energy savings.
  • ✓
    Pro Installation: These systems require careful static pressure calculation and drainage planning by licensed HVAC pros.

Frequently Asked Questions

? Can I use concealed units in a multi-zone setup? ›
Absolutely. You can mix and match. For example, use a concealed duct for the master bedroom (to keep it invisible) and standard wall units for other bedrooms, all connected to a single multi-zone outdoor condenser.
📐 How much ceiling space do I need? ›
Slim duct air handlers are incredibly compact, usually requiring only 8 to 10 inches of vertical clearance. They are designed to fit between standard floor joists or in a dropped soffit.
🛠️ Do I need an access panel? ›
Yes. For long-term maintenance (filter cleaning and electronics access), a small service hatch or access panel is required. This can often be integrated into the return air grille for a seamless look.
🌬️ Can one concealed unit cool two rooms? ›
Technically yes, if the rooms are adjacent and you use ductwork to split the airflow. However, they will share the same thermostat setting. For independent control, a multi-zone system with separate units is recommended.
⚡ Are they more expensive to install than wall units? ›
The installation cost is generally higher because it involves ductwork, grilles, and ceiling work. However, the added property value and superior aesthetics make it a preferred choice for high-end residential projects.
🔇 How loud are concealed systems? ›
Since the unit is hidden behind drywall and insulation, they are often even quieter than wall-mounted units. You typically only hear a gentle whisper of air from the grilles.
