WHISPER-QUIET COOLING WITHOUT DUCTWORK
Sizing your wine cooling unit
Square footage doesn't cool a wine cellar.
BTU load does.
Most homeowners — and unfortunately many contractors — size a cooling unit off room area alone. That approach ignores the variables that actually determine how hard a compressor has to work, and it’s the single biggest cause of oversized, undersized, and short-cycling wine cellar cooling systems.
The Common Mistake...!
Sizing by square feet
“My room is 200 sq ft, so I need a 5,000 BTU unit” ignores everything that actually drives heat gain into the cellar.
- Leads to units that run constantly and still can’t hold temperature
- Or units that short-cycle, causing humidity swings that damage corks and labels
- Doesn’t account for insulation, glass, or sun exposure
- Ignores ceiling height and true cubic volume
The Correct approach...!
Sizing by BTU heatload
A proper heatload calculation measures the actual thermal load your cellar generates, in BTU/hr — the only number a compressor cares about.
- Accounts for wall & ceiling insulation R-value
- Factors in glass doors, windows, and sun exposure
- Includes room volume, not just floor area
- Matches ambient temperature outside the cellar
01 — Cubic Volume
Ceiling height changes total air volume even when the floor space stays the same.
02 — Insulation
Wall, ceiling, and vapor barrier quality determine how much heat penetrates in cellar.
03 — Glass & Doors
Glass walls and doors gain heat far faster than insulated walls, especially in direct sun.
04 — Ambient temp
The temperature and humidity of the space surrounding your cellar changes the load significantly.

Frequently Asked Questions
Certainly! Here are some frequently asked questions (FAQs) about winezone ductless split systems.
A WineZone ductless split system is a two-part wine cellar cooling solution consisting of an indoor evaporator and a remote condenser installed outside or in another space. These components are connected via refrigerant lines, eliminating the need for ductwork and keeping heat and noise out of the cellar.
The indoor unit (evaporator) cools the air inside the wine cellar, while the remote condenser dissipates heat elsewhere. This separation ensures quiet operation and stable temperature control without introducing excess heat into the cellar.
- Quiet operation due to remote condenser placement
- No ductwork required
- Economical to purchase and install
- Precise temperature control via digital thermostat
- Reduced heat buildup inside the cellar
No. These systems are designed to be extremely quiet because the condenser (the loudest component) is located outside the wine cellar, significantly reducing noise and vibration within the space.
They are ideal for:
- Rectangular wine cellars with limited airflow requirements
- Spaces without room for ducting or mechanical equipment
- Concrete or brick-enclosed cellars
- Retrofit or already constructed wine rooms
No. These systems are specifically designed for installations where a mechanical room is not available, making them ideal for residential and retrofit applications.
Yes. WineZone ductless split systems offer flexibility with either indoor or outdoor condenser installation, allowing heat to be removed from the cellar efficiently.
Capacity depends on the model. For example, certain WineZone ductless systems can handle cellars up to approximately 2,000 cubic feet, but proper sizing should always be calculated based on insulation, glass, and ambient conditions.
Ductless split systems primarily focus on temperature control. Additional humidity control may require a dedicated humidification system or upgrading to an air handler system with built-in humidity management.
Yes. WineZone ductless split systems must be installed by a qualified HVAC technician to ensure proper refrigerant handling, system performance, and warranty compliance.
- Ductless split: No ductwork, wall-mounted evaporator, easier installation
- Ducted system: Uses hidden ductwork, better for complex or large layouts
Ductless systems are typically more cost-effective and simpler to install, while ducted systems provide more uniform air distribution in larger or irregular spaces.
Yes. By eliminating duct losses and isolating cooling to a specific space, ductless systems operate efficiently while maintaining stable wine storage conditions.
WineZone ductless systems are generally designed for shorter line runs and are best suited for applications requiring less than approximately 15 feet of air “throw,” making them ideal for compact to mid-sized wine rooms.
These systems are controlled by a 24V digital thermostat with a large display, allowing precise and easy temperature adjustments.
