    When to "Size Up"

    High Ceilings (10ft+)

    If your ceilings are 10 feet or higher, you are cooling a larger volume of air. We recommend increasing your BTU choice by 20%.

    Poor Insulation

    For older homes or buildings with single-pane windows, opt for the next size up to ensure the unit can maintain the set temperature.

    Kitchen Environments

    Appliances generate significant heat. If the unit is for a kitchen, add 4,000 BTUs to your square footage calculation.

    Heavy Sun Exposure

    Rooms with large south-facing windows or "sunrooms" act like greenhouses. Increase your BTU capacity by 10-15%

    Occupancy

    If the area regularly hosts more than two people (like a conference room or classroom), add 600 BTUs per additional person..

    Frequently Asked Questions

    A: Unlike standard mini splits that mount directly on your wall, concealed duct indoor air handlers are ultra-slim mechanical boxes engineered to be completely hidden from view. They are typically installed above drop ceilings, inside attics, below floor joists in crawlspaces, or tucked away inside nearby closets. The treated air is then quietly channeled into the room via brief duct runs terminating in subtle, flush-mounted wall or ceiling grilles.

    A: Yes, absolutely. Every concealed duct air handler connected to your multi-zone outdoor condenser acts as an entirely independent zone. Each space is governed by its own dedicated wall thermostat or wireless remote, allowing you to cool down an active kitchen or living space while completely shutting off or dialing back heating and cooling in unoccupied guest bedrooms.

    A: Because these systems are intentionally engineered for low-clearance residential and commercial retrofits, most slim duct air handlers feature a profile height of only about 7.5 to 11 inches. This incredibly compact vertical footprint allows them to slip comfortably into standard ceiling joists or tight furry-down spaces without drastically lowering your finished ceiling height.

    A: Most premium multi-zone concealed duct indoor units (such as our packages from ACiQ and Cooper&Hunter) come standard with a factory-installed, internal condensate lift pump. Because these units sit level inside flat ceiling spaces where natural gravity drainage can be difficult to angle, the integrated lift pump actively forces collected water up and out into your primary drainage line, preventing structural leaks.

    A: Just like any traditional HVAC system, the primary maintenance task is regular air filter cleaning or replacement to preserve high static airflow and equipment longevity. Since the actual air handler box is hidden behind drywall or inside a ceiling panel, installers configure a return air grille with an easy-access hinge, allowing you to slide the air filter out and clean it in seconds without needing to enter the ceiling envelope.
