How it works
Buying a split system, step by step
A split system is a two-part install, so it pays to plan it before you order. Here is what happens, and where we help.
Size the cellar
Split systems are sized to the room, not just the cubic feet. Glass, stone, lighting and the temperature outside the cellar all change the load. Send us the details for a free heat-load check.
Use the cellar calculatorChoose the system
Pick the evaporator style (wall-mounted, ceiling, ducted or concealed) and the condenser. The 220V Advanced H.E. condenser is built for outdoor installs; the 110V condenser suits indoor spaces like a garage, attic or mechanical room.
Plan the install
A licensed HVAC/R technician runs the line set between the two units, charges the system and starts it up. The line set, drain line and any ducting are sourced separately. Your installer will confirm the run length and power.
Activate the warranty
The 2-year limited warranty starts on the purchase date and is activated once your technician submits WhisperKOOL's Product Warranty Checklist and WhisperKOOL approves it. We help you with the paperwork.

A note on the 24V Thermostat Conversion Kit: if selected, the system will not be built with the standard WhisperKOOL control or liquid-temperature bottle probe — you'll need to source your own compatible 24V thermostat. Our support team does not provide technical support for third-party smart thermostats.
Full technical specifications — dimensions, weight, electrical requirements, and complete BTU ratings by fan speed and configuration — are available in the official WhisperKOOL Product Specification Sheet.

Product Documentation & Resources
Frequently Asked Questions
Can this cooling system be hidden in a soffit?
Yes — soffit installation is one of the Mini Blow-Through's intended applications. It can be positioned in a soffit, ceiling cavity, custom cabinet, attic, or adjacent mechanical space, with airflow directed into the cellar through your chosen ducted, ductless, or hybrid configuration.
What's the difference between the ducted, ductless, and hybrid airflow kits?
The ducted kit connects both supply and return air to insulated ductwork, giving the most flexibility in equipment placement. The ductless kit uses directional deflectors for both airflow paths — well suited to soffits and cabinetry with short, direct airflow. The hybrid kit ducts one side while using a deflector on the other, useful when only one airflow path needs to reach a remote register.
Do I need a professional to install this system?
Yes. This is a split refrigeration system that must be installed, commissioned, and charged by a qualified, licensed HVAC/R technician. Installation by an unqualified party will void the warranty, and the split-system warranty checklist must be completed by the installing technician before coverage is activated.
Is this a good fit for a glass wine cellar?
Glass wine cellars are listed among the Mini Blow-Through's ideal applications by WhisperKOOL, alongside residential wine rooms, commercial wine displays, and custom millwork. As with any cellar type, we recommend a professional heat-load calculation to confirm the right configuration for your specific space before ordering.
How large of a wine cellar can the Mini Blow-Through cool?
Approximately up to 500 cubic feet when the cellar is fully insulated, properly sealed, and protected by a continuous vapor barrier. A heat-load calculation is still required, since glass, doors, lighting, and construction materials can all change the actual capacity your space needs.

Questions, answered
WhisperKOOL split system FAQ
Straight answers from the team that sizes, installs and services wine cellar cooling every day.
Do I need an HVAC technician to install a split system?
Yes. A split system has two units joined by refrigerant lines, so a licensed HVAC/R technician has to install it, charge it and start it up. Installing it any other way voids the WhisperKOOL warranty.
What is not included in the box?
The copper line set that connects the evaporator and condenser is not included, and neither is the drain line or any ducting for ducted models. An exterior housing for an outdoor condenser is available as an option. Your technician will size the line set for your run.
How far can the condenser be from the cellar?
On Platinum, Ceiling Mount and Quantum systems the condensing unit can sit up to 100 line feet from the evaporator, so it can go outdoors, in a garage, attic or mechanical room. Ducted evaporators can sit up to 25 duct feet from the cellar. Exact limits for each model are in its owner's manual.
110V or 220V Advanced H.E. condenser: which one?
The 220V Advanced H.E. condenser is made for outdoor installs: a larger coil, quieter fans and lower power use, and it copes with extreme temperatures. The 110V condenser suits indoor spaces such as a garage, attic or mechanical room. If you are unsure, tell us where it will go and we will recommend one.
Will it run in cold weather?
Split condensers are designed for roughly 20°F to 110°F. For colder locations, WhisperKOOL's cold weather start kit keeps the system running well below freezing, and it is included with many models. Check the product description, or ask us before you order.
How does the warranty work on a split system?
WhisperKOOL split systems carry a limited 2-year product warranty from the purchase date. It is activated once the installing technician submits the Product Warranty Checklist and WhisperKOOL approves it. As an authorized dealer, we help you register the system and file any claim.
Can I order online or do I need a quote?
Both work. If you already know the model, condenser and options, you can add it to your cart. If you want help choosing or want the full system priced in one place, request a quote and our team will send you an itemized recommendation.
