Wine Cellar Cooling Systems 101: Types, Sizing & Noise 

Why Active Cooling Beats Passive Storage

Wine ages gracefully only when change is slow. A single week at 75 °F can mute fruit aromas and push corks. Most modern basements swing > 10 °F between seasons—too risky for a serious collection.
Active wine‑cellar cooling units solve two critical problems: stable temperature and elimination of vibration/noise.

Three Cooling Compared

| Architecture | Install Difficulty | Noise in Cellar | Best For |
| Through‑wall (self‑contained) | DIY‑possible | 60–70 dB | Budget or utility spaces |
| Split system | HVAC tech required | 35–45 dB | Retrofits, garages |
| Fully ducted split (Panthaire APEX) | Pro install + ductwork | Luxury homes, glass walls |

Panthaire manufactures only fully ducted APEX units to deliver near‑silent performance and a clean aesthetic.

How to Size Your Cooling Unit

1  Calculate volume (L × W × H).
2  Multiply by insulation/glass factor (R‑20 = 1.0; heavy glass = 1.3).
3  Match BTU from quick table:
• 500 cu ft, good insulation → 1 800 BTU
• 1 000 cu ft, glass door → 3 200 BTU

Noise & Vibration Matter

Anything above 55 dB equals normal conversation; constant vibration accelerates ageing. Ducted systems place the blower outside the cellar, keeping internal dB near whisper level.

Installation Snapshot

Dedicated 15–20 A circuit
• 6 mil poly vapor barrier on warm side
• Condensate drain or pump
• Duct runs ≤ 25 ft, sealed at every joint
• Clear 18 " around condenser for airflow

Key Takeaways

• Match BTU to heat load—oversizing wastes energy; undersizing strains components.
• Prioritise silence for visible cellars.
• Professional design prevents 90 % of post‑install issues.
