12 steps to Build Your DIY Wine Cellar Cooling System
1. Determine the location and size of your wine cellar.
Before you start building, decide where to place the wine cellar in your home, and measure the size of your wine room to determine the cooling capacity you need.
An active wine cellar is a room where the temperature has to be maintained. Some have passive wine cellars – where the ambient temperature is used instead of an air conditioner – as in the case of basement cellars, where the environment is more regulated.
A larger cellar will require a more powerful cooling unit. In addition, think about the volume of the space or if you need to install wine racks and a fridge inside your wine cellar.
Another critical factor is the number of bottles you plan on storing in your cellar. The average cooling unit can typically handle around 800 to 1000 bottles. Still, if you have a more extensive collection or plan on expanding, you may want to invest in a bigger unit.
You'll also want to consider the cooling unit you use.
The self-contained system is typically more affordable and easier to install but may be less effective for more enormous cellars.
Split system units offer more powerful cooling capabilities and can be customized to accommodate your needs.
2. Choose a location for the cooling unit.
Decide where to place your cooling unit to cool the entire room efficiently. If it's exposed to warm air or natural light, you'll need a stronger unit to combat the extra heat.
3. Select a cooling unit.
Choose a cooling unit based on the size of your residential wine cellar and the cooling capacity you need. You can choose a pre-made unit or build one using a refrigeration system, a thermostat, and a fan.
Picking a suitable cooling unit for your wine cellar design is a good idea to ensure that your precious vintages are kept at the perfect temperature and humidity levels.
It can be challenging to know where to begin since there are many options in the market. But here are the critical factors you need to remember:
- Consider the size of your wine cellar, the size of the cooling unit, and the type of cooling technology used. Through-the-wall cooling units are great for those with a limited budget. If you have a small wine cellar, choose the cooling systems that can handle 300 cubic feet to 1,000 cubic feet to maintain the ideal temperature and save energy in the long run.
- Ensure the wall units are powerful enough to effectively cool your space and energy-efficient to keep your utility bills in check.
- Factor in the unit's noise level—no one wants a loud HVAC system disrupting their wine-tasting experience.
- Think about wine cellar cooling system maintenance. Regular upkeep can extend the life of your unit and prevent costly repairs down the line. This includes simple tasks like replacing the air filter, checking the refrigerant levels, and cleaning the evaporator coils. However, if you're uncomfortable performing these tasks, it's worth investing in professional maintenance services to keep your cooling system running smoothly.
