Concealed Installation
Ducted mini-split air handlers can be hidden above ceilings, in attics, closets or other suitable spaces so only supply and return grilles are visible.
Get the efficiency and zoning flexibility of a mini-split with the clean appearance of traditional supply registers. Concealed ducted air handlers can serve one room or multiple nearby spaces while keeping the indoor equipment largely out of sight.
Concealed equipment, flexible air distribution and ductless-system technology in one professionally designed comfort solution.
Ducted mini-split air handlers can be hidden above ceilings, in attics, closets or other suitable spaces so only supply and return grilles are visible.
A properly designed short-duct system can distribute conditioned air to multiple nearby rooms from one compatible indoor unit.
When matched with compatible heat-pump outdoor equipment, ducted indoor units can provide efficient cooling and heating.
Supply registers can be positioned to improve room coverage while keeping the indoor equipment out of sight.
Locating the air handler away from occupied areas can help reduce perceived indoor equipment noise when the system is properly designed.
A ducted air handler can serve as the indoor component of a compatible dedicated single-zone mini-split system.
Some ducted air handlers can be combined with other compatible indoor-unit styles on approved multi-zone systems.
Concealed ducted systems preserve wall and ceiling surfaces where visible wall heads or cassettes are not preferred.
Unlike a wall-hung or floor-console indoor unit that conditions a room directly, a ducted mini-split air handler uses supply and return ductwork. This allows the indoor equipment to be concealed while conditioned air enters the space through registers or diffusers.
These systems are especially useful when you want the zoning benefits of mini-split technology without a visible indoor head in each room. Explore our HVAC installation services, mini-split categoriesand HVAC load calculations.
A properly designed ducted mini-split can provide discreet zoned comfort across a wide range of spaces.
A concealed air handler can serve one room or a small group of nearby rooms when duct design and load requirements allow.
Useful for additions that need independent comfort without extending the home's primary duct system.
A compact ducted system may fit qualifying attic layouts while serving rooms through short duct runs.
Provides discreet heating and cooling where visible indoor heads are not desired.
Concealed equipment and distributed supply air can create a clean professional appearance.
Suitable for qualifying light-commercial applications that benefit from hidden equipment and flexible register placement.
One ducted indoor unit may serve multiple nearby spaces when loads, airflow and duct design are properly engineered.
A strong choice when interior design requirements call for minimal visible HVAC equipment.
Depending on the manufacturer and equipment family, a ducted air handler may be paired with a dedicated outdoor unit or connected to a compatible multi-zone system. Some multi-zone platforms allow concealed ducted air handlers to operate alongside wall-hung, ceiling cassette and floor-mounted indoor units.
A ducted mini-split must move the required amount of air through its duct system while remaining within the manufacturer's allowable external static pressure. Undersized ducts, restrictive filters, poor return-air design and excessive fittings can reduce airflow and performance.
Professional design may include room-by-room load calculations, airflow targets, duct sizing, return-air planning, register selection and static-pressure verification during commissioning.
Learn About Load CalculationsCorrect load sizing, duct design, airflow, drainage, refrigeration practices and commissioning all contribute to reliable comfort.
Review room loads, insulation, windows, occupancy, available equipment space and comfort goals.
Determine heating and cooling requirements instead of selecting capacity from square footage alone.
Calculate required airflow, external static pressure, duct sizes, return-air paths and register locations.
Verify manufacturer-approved indoor/outdoor combinations, refrigerant requirements and connected capacity.
Determine condensate drainage, line-set routing and outdoor-unit placement.

A ducted mini-split air handler is an indoor unit connected to compatible mini-split outdoor equipment that distributes conditioned air through supply and return ductwork.
Yes. The indoor unit uses ductwork for air distribution, but it can still be part of a compatible single-zone or multi-zone mini-split heat-pump system.
A wall-hung head delivers air directly into the room, while a ducted air handler is concealed and distributes air through ducts and registers.
A ceiling cassette delivers air directly from a visible ceiling grille, while a ducted air handler normally connects to separate supply and return grilles through ductwork.
Yes, in qualifying applications. The number of rooms depends on heating and cooling loads, required airflow, duct design and the capabilities of the selected equipment.
When paired with compatible heat-pump outdoor equipment, many ducted mini-split systems provide both heating and cooling.
Depending on the model and building, it may be installed in an attic, ceiling cavity, closet, mechanical space or other approved location with adequate service access.
They require an appropriate return-air path. The exact return arrangement depends on equipment design, installation location and duct-system design.
Sometimes, but existing ducts must be evaluated for sizing, leakage, condition, insulation, airflow and static-pressure compatibility.
External static pressure represents resistance to airflow outside the air handler. Ducted equipment must operate within the manufacturer's allowable static-pressure range.
Excessive resistance can reduce airflow, increase noise, hurt performance and create comfort or equipment problems.
Yes. Proper equipment sizing should be based on the actual heating and cooling loads of the spaces being served.
No. Oversized equipment can cause short cycling, comfort issues and poor humidity control. Proper sizing is important.
Some manufacturer-approved multi-zone systems allow concealed ducted, wall-hung, cassette and floor-mounted indoor units to be combined.
Yes, when the selected indoor air handler and outdoor unit are an approved single-zone match.
They can provide very quiet occupied-space comfort when equipment placement, duct design, airflow and vibration isolation are properly addressed.
Yes. Cooling and dehumidification produce condensate that must be drained correctly.
Yes. A properly designed return-air system should include filtration appropriate for the equipment and installation.
Compatible filtration and indoor-air-quality options may be available, but airflow resistance and manufacturer requirements must be considered.
Ducts located outside conditioned space or where condensation can occur generally require appropriate insulation and vapor control according to applicable requirements.
