Is the WhisperKOOL Mini Ceiling Mount Right for Your Cellar? The WhisperKOOL Mini Ceiling Mount is designed for properly insulated residential wine cellars up to 500 cubic feet. It is best suited for installations where wall space is limited and a split system is preferred to reduce in-cellar noise and vibration. This unit requires: R19 minimum wall insulation R30 ceiling insulation A continuous 6 mil vapor barrier A sealed cellar door A dedicated 15-amp electrical circuit Professional HVAC installation If these conditions are not met, cooling performance may decline and system lifespan may be reduced. Available in WhisperKOOL Mini Ceiling Mount 220V Condenser & Mini Ceiling Mount 110V for 500 cu.ft. Other Sizes: WhisperKOOL Ceiling Mount 4000 for 1000 cu.ft. wine cellar, WhisperKOOL Ceiling Mount 8000 for 2000 cu.ft. wine cellar, WhisperKOOL Ceiling Mount Twin 9000 for 3000 cu.ft. wine cellar and WhisperKOOL Ceiling Mount Twin 12000 for 3500 cu. ft. Best For Fully insulated residential wine cellars under 500 cu. ft. Ceiling installations where wall space is limited Remote condenser placement (up to 100 ft away) Homeowners seeking quieter split-system operation Not Ideal For Glass-heavy wine walls without load adjustments Stone or concrete rooms without proper insulation Commercial wine storage Condenser environments exceeding 110°F intake air Poorly sealed or improperly vapor-barriered rooms If your cellar exceeds 500 cu. ft. or includes significant glass exposure, consider upgrading to a larger model such as the Ceiling Mount 4000. How This System Works The Mini Ceiling Mount is a split cooling system: Evaporator (Fan Coil Unit) installs through the cellar ceiling Condenser (Air-Cooled Unit) installs remotely (attic, mechanical room, or exterior with protective housing) The system draws warm air from the ceiling, cools it, and redistributes conditioned air throughout the cellar. Because the compressor is located outside the cellar, vibration and operational noise inside the room are minimized. Performance Capabilities & Limits Designed to maintain 55°F cellar temperature Performance rated at 2167 BTU/h at 85°F condenser intake temperature Can operate with condenser intake air up to 110°F Above 110°F intake temperature, cooling efficiency may decline. Installations in unconditioned garages or extreme desert climates may require a larger system. Humidity is reduced during cooling cycles. This unit does not independently control humidity. Technical Specifications Cooling Capacity 2167 BTU/h (at 85°F condenser intake air temperature) BTU output assumes a fully insulated, sealed cellar. Glass, exterior walls, or inadequate insulation increase heat load. Maximum Cellar Size Up to 500 cubic feet Sizing assumes: R19 wall insulation R30 ceiling insulation Proper vapor barrier Minimal glass exposure Undersized systems may fail prematurely or struggle to reach set temperature. Temperature Delta Maintains 55°F cellar temperature with condenser intake air up to 110°F under proper insulation conditions. Refrigerant R-134a refrigerantCommonly used in wine cellar systems. Subject to environmental regulation changes over time. Electrical Requirements 115V (15-amp dedicated circuit required)Sharing the circuit with other appliances may cause performance instability or breaker trips. Amperage Evaporator: 1 running ampCompressor: LRA 26 / RLA 4.4 Horsepower 1/6 HP Noise Level Approximately 51 dBAComparable to a quiet conversation. Dimensions Evaporator: 22.05”L x 11.08”W x 11.34”HCondenser: 13.97”L x 15.85”W x 9.86”H Weight 50 lbs (Evaporator)50 lbs (Condenser) Line Set Requirements Liquid line: 1/4”Suction line: 3/8” (under 50 ft.) 1/2” (over 50 ft.) Correct line sizing is critical for compressor longevity and oil return. Drain Line 1/4” ID clear plastic tubing Installation Evaporator installs through the cellar ceiling.Condenser may be installed up to 100 line feet away. Professional HVAC-R technician required. Failure to use qualified installation may void warranty. Thermostat Advanced digital display with 50-ft cableIncludes 50-ft liquid-temperature bottle probe for accurate wine temperature measurement. Warranty Two-year limited warranty (parts and labor)Warranty requires proper professional installation. Manuals for WhisperKOOL Mini Ceiling Mount Ductless Split: Owner's Manual for WhisperKOOL Mini Ceiling Mount Ductless Split System Technician's Manual for WhisperKOOL Mini Ceiling Mount Ductless Split System Mini Ceiling Mount vs Ceiling Mount 4000 Feature Mini Ceiling Mount Ceiling Mount 4000 Max Cellar Size 500 cu ft 1000+ cu ft BTU Output 2167 Higher capacity Best Use Case Small residential Larger residential Glass Suitability Limited Better tolerance Electrical 115V May require higher amp If your cellar includes large glass panels or exceeds 500 cubic feet, upgrading reduces strain and improves long-term reliability. Installation Considerations Most system failures result from: Inadequate vapor barriers Undersized equipment Excessive condenser heat exposure Shared electrical circuits Improper line set sizing Confirm insulation and vapor barrier integrity before selecting a cooling system. Optional Accessories Exterior Protective Housing Required for outdoor condenser installations. Protects from rain and environmental exposure. Condenser Coil Coating Recommended for coastal environments to protect against salt air corrosion. 24V Thermostat Conversion Kit (Optional) Allows integration with compatible smart thermostats (thermostat not included). Final Guidance The WhisperKOOL Mini Ceiling Mount is a strong solution for small, properly insulated residential wine cellars where ceiling installation is preferred and condenser noise separation is desired. Proper sizing and installation determine long-term reliability. When in doubt, verify insulation values and total heat load before selecting a system.
