Yes—through‑the‑wall units (e.g., TTW018) are designed for DIY installation without needing a contractor . However, ducted, ducted split, and ductless split systems require licensed HVAC installers

Wine Guardian units are known for quiet operation (especially ducted and split systems installed outside the cellar) and high energy efficiency. They use commercial‑grade components built in the USA.

Ideal cellar temperature is usually 55–57 °F (12–14 °C), though a range of 45–65 °F may be acceptable. For humidity, aim for around 60–80% RH to keep corks moist and prevent oxidation

No. Regular air conditioners are not designed to maintain the stable temperature and high humidity wine requires. Standard AC units can cause fluctuations and dry out corks, harming wine quality.

Through-the-wall systems range from ~999 to 1,845 BTU/hour, ductless split units cover 2,900 to 4,300 BTU/h, ducted systems scale from 3,760 to 15,680 BTU/h, and split systems reach up to ~14,900 BTU/h—serving cellars of all sizes.

Yes, you can add integrated or standalone humidifiers to any cooling system. Many units include humidity display/control options, and packaged humidifier bundles are available.

All Wine Guardian cooling systems and humidifiers are made in the USA and come with a two‑year factory warranty.

Yes. Their units are rated at 80°F (27 °C) ambient and sized accordingly. In hot climates like Las Vegas, additional capacity may be needed to compensate for higher incoming heat loads.

Annual servicing is recommended: cleaning coils, checking refrigerant, inspecting controls, and testing the humidifier/water kit (if installed). Proper maintenance ensures longevity and prevents issues like frozen coils or thermostat errors.

Through-the-wall units can often be DIY-installed. Ducted self-contained, ducted split, and ductless split systems must be installed and serviced by licensed HVAC/Refrigeration professionals experienced with Wine Guardian products.

Typical problems include insufficient cooling, high/low humidity, the unit not cycling on/off, or the evaporator freezing. Wine Guardian provides a detailed Troubleshooting Wizard that covers thermostat settings, airflow restrictions, safety switch resets, and coil inspection.
