Product Overview
The WhisperKOOL Ceiling Mount 4000 Ductless Split System is built for collectors who want reliable wine cellar cooling without a visible wall-mounted unit. The evaporator mounts flush into the ceiling, draws warm air upward, and circulates cooled air throughout the cellar.
Because this is a split system, the condenser is installed remotely from the wine room. This helps reduce mechanical noise inside the cellar and supports a more refined wine room design.
Updated design details include bottom-mounted wiring and line-set access, flare fittings that eliminate on-site brazing, e-coated Duramax coils, a redesigned hex mesh grille, and a startup air filter for added system protection.
Collectors who want discreet ceiling-mounted cooling
Properly insulated and sealed cellars up to approximately 1,000 cu. ft.
Projects where the condenser can be installed remotely
New construction or planned cellar remodels
Not Recommended For
DIY installations
Uninsulated rooms or spaces without a vapor barrier
Cellars larger than 1,000 cu. ft. without professional sizing review
Temporary wine storage areas
Projects without ceiling access for installation and service
Applications where a self-contained plug-and-play unit is preferred
Free Wine Cellar Design Assistance
Wine Coolers Empire can help confirm cellar size, insulation, vapor barrier quality, ceiling access, condenser placement, and system fit before purchase.
The evaporator is designed to mount flush with drywall or sheetrock and fit between ceiling joists for a clean integrated appearance.
Ductless Split Performance
The split design separates the evaporator from the condenser, moving heat and mechanical noise away from the wine cellar.
KDT Digital Touch Display
The KDT Digital Touch Display can be installed up to 50 feet away from the unit and includes Advanced System Protection alerts.
Liquid Temperature Bottle Probe
The included bottle probe measures liquid temperature for a more accurate reflection of wine temperature than ambient air alone.
Startup Air Filter
The startup air filter helps protect the unit from debris during installation, cellar construction, and rack installation.
Optional 24V Thermostat Conversion
The optional conversion kit allows the system to work with compatible 24V smart thermostats for Wi-Fi control and monitoring.

Limitations
Nearly invisible ceiling-mounted installation
Requires professional HVAC-R installation
Remote condenser helps reduce cellar noise
Requires refrigerant line-set routing
Strong fit for luxury cellar designs
Requires ceiling access and proper framing
Liquid temperature monitoring improves wine protection
Not suitable for poorly insulated rooms
Optional smart thermostat compatibility

Installation Requirements
Warranty Requirement: This system must be installed by a qualified HVAC-R technician. Improper installation can void the warranty and may cause performance problems.
Required Installation Considerations
Ceiling framing and joist spacing must support the ceiling-mounted evaporator.
The wine cellar must be fully insulated and sealed.
A proper vapor barrier is required for stable cellar performance.
Refrigerant line-set routing is required between the evaporator and condenser.
Electrical wiring must be completed by a qualified professional.
Condensate drainage must be planned before installation.
Condenser placement must allow proper ventilation and service access.
Drain Line Requirement
The WhisperKOOL Ceiling Mount 4000 requires a 1/4" ID clear plastic drain line. Drain tubing is not provided.
Confirm drain routing before installation so condensate can be managed properly and service access remains available.
BTU/h and Sizing Notes
The WhisperKOOL Ceiling Mount 4000 has an estimated cooling range of 4,000-6,087 BTU/h. This value is an estimate and not a guarantee for every 1,000 cubic foot wine cellar.
Actual cooling requirements depend on cellar construction, insulation, vapor barrier quality, glass exposure, ambient temperature, door type, and other design variables. Cellars with glass, stone, concrete, poor insulation, or high ambient heat may require a larger system.
Choosing an undersized unit can result in excessive runtime, unstable temperature, and premature equipment failure. Request a sizing review before purchase if the cellar has high-load materials or unusual ambient conditions.
The optional 24V Thermostat Conversion Kit allows compatible third-party smart thermostats to monitor and control the wine cellar environment.
Connect compatible thermostats to Wi-Fi
Control temperature from a phone, tablet, or laptop
Monitor runtime and energy usage
Set alarm notifications
View cellar conditions remotely
Please Note: WhisperKOOL does not provide smart thermostats. If the 24V Thermostat Conversion Kit is selected, the system will not be built with the standard WhisperKOOL control or liquid measuring bottle probe. A compatible 24V smart thermostat must be purchased separately. WhisperKOOL support does not provide troubleshooting for third-party smart thermostat issues.
Optional WhisperKOOL Accessories
