Cooling Unit Installation for a Residential Wine Cellar in Orange County

Awesome custom wine room in Orange County, California with cooling unit.

Awesome custom wine room in Orange County, California with cooling unit.

We at M&M Cellar Systems were recently contacted by Vintage Wine Cellars and asked for help on one of their projects. Vintage Cellars is one of the biggest wine cellar builders in the country. Their central office is in Southern California and they do a lot of projects in Orange County and Los Angeles, regularly asking us to assist with cooling unit installation.

This impressive wine room was to be built with traditional wood wine racks and modern stainless steel metal rods, merging both old and modern design aesthetics. The entirety of the room would be visible from the outside by large glass walls and doors. This residential wine cellar measures 16 feet wide, 5 feet deep, and 9 feet high.  The total bottle storage capacity is 1,150 wine bottles.

The Wine Rack Designs

Vintage Wine Cellars used a combination of different wine rack designs.  There are single bottle storage racks, horizontal display racks, solid diamond bins, case drawers, and stainless steel metal rods.  The wine rack designs are actually a mix of traditional and modern wine storage styles.

Finding the Best Wood Option

The wooden wine racks are made of Sapele Mahogany.  Mahogany is one of the best wood species, due to its natural beauty, longevity, workability, and compatibility with wood stains.  The stain used for the wooden wine racks is a dark walnut stain, with a clear lacquer finish.

Wine Cellar Doors

A wine cellar door is an essential element in every wine room.

A Door That Protect the Wine Cellar’s Climate Conditions

In order to maintain the ideal humidity and temperature inside the wine cellar, it must have an air tight seal.  This is what wine cellar doors are for–they keep wine cellars insulated while providing a method of  access.

A Door That Offers Quality Design Elements

Aside from the functional aspects of wine cellar doors, they should also enhance the aesthetic appeal of a wine room. Wine cellar doors can be customized to reflect the style preference and personality of the owner.

Residential Wine Cellar Refrigeration Unit

Glass Wine Cellar DoorsThe wine cellar cooling unit used for this climate controlled wine cellar is an SLD split wine cellar cooling system.  This type and model of cooling unit is ideal for many residential wine cellars.

Initially, the wine cellar cooling unit installation was a bit of a challenge due to the size of the cellar and the all-glass-front.  At least 10,000 BTUs were needed to cool the room down to 55 degrees Fahrenheit.

Wine Cellar Cooling System Design

The first design had a fully ducted commercial grade high static system, which would be installed in the attic.  But it turned out that the attic did not have enough space because the air handler for the house was already kept there. This resulted in a redesign that allowed the evaporator coil of the cooling unit be hidden in the wine racks.

The SLD Split Wine Cellar Cooling Unit

The split wine cellar cooling system by SLD was chosen for this wine room because of its versatility and functionality.  It is designed for medium to high temperature wine storage spaces.

The wine cellar cooling systems team installed the cooling unit horizontally, and covered it with a louvered grill, which was made of the same wood as the wine racks.

The Importance of Regular Maintenance for Wine Cellar Cooling Units in Corona Del Mar

Wine cellar cooling units must always be functioning properly, so that your wine collection is not at risk of spoiling. Regular maintenance is necessary to make sure that your wine cellar refrigeration system is constantly providing your wines with the climate conditions that they need. This service call to fix a wine cellar cooling system in Corona del Mar is a perfect example of why regular maintenance is very important. 

Wine Cellar Cooling Units – An Essential Part of Proper Wine Storage

Those who want to venture into the art of wine collecting know that wine is a wonderful investment. It is a product that increases in value over time as long as it is kept in the ideal conditions. To protect their investment, wine enthusiasts should make sure that they have an effective wine storage solution first, before starting their wine collection.

Wine Cellar Cooling Units in Corona del Mar

Residential wine cellars allow easy access to your favorite wines, since you do not need to go elsewhere to get a bottle from your collection. Also, they provide an opportunity to be creative and a chance to flaunt your collection to your guests and friends.  Home wine cellars come in various designs and styles, that range from simple to elaborate.

A wine cellar refrigeration unit is an essential part of a residential wine cellar, because it is the unit that provides the cellar with the cool air that wines need. Each residential custom wine cellar needs a different wine cellar cooling system, depending on its storage needs.

The Need to have Regular Maintenance for your Wine Cellar Refrigeration System

Wine cellar refrigeration units are responsible for providing the cool air necessary inside a wine storage room. An efficient wine cellar cooling unit is one that can provide the ideal temperature and humidity levels with minimal to no fluctuations. You will know if your wine cellar refrigeration system is no longer functioning properly if the temperature and humidity are no longer in the ideal levels. Ideally, the temperature inside a residential custom wine cellar should be within 55 to 60 degrees Fahrenheit, while the humidity should be within 60% to 70%. There can be many causes a poorly functioning wine cellar cooling system, but in order to avoid most problems, and to prevent the worsening of existing problems, regular maintenance should be done.

Service Call to Fix a Wine Cellar Cooling System in Corona del Mar

Ideal Wine Storage

Wines Need a Wine Cellar with a Cooling Unit Installed

One of the best examples of why it is very important to have regular maintenance services done on a wine cellar cooling unit is a recent service call that M&M Cellar Systems received. The service call was to fix a poorly functioning wine cellar refrigeration system in Corona del Mar, a city in Newport Beach, California.

The client’s wine cellar cooling unit was an LPQ 6600, which is generally a very reliable type of cooling unit. The client called to complain that the unit was no longer cooling the wine cellar, due to a leak found in the unit’s condenser. The client had never had this wine cellar cooling unit go through regular maintenance before, and had neglected it.

After inspection and investigation, it was found that the leak was possibly caused by the poor installation of the wine cellar cooling system. The refrigeration lines were found buried in the ground, with no protection cover. This also caused leaks.

Repair personnel from M&M Cellar Systems repaired the leak and did the necessary corrections. Fortunately, no permanent damage was caused by the leak. Also, it was a good thing that the client made the service call, because if they waited longer before acting on the problem, more serious damage could have occurred.

The client’s LPQ 6600 wine cellar refrigeration unit is now functioning properly, and cooling the residential custom wine cellar in the right temperature and humidity levels for proper wine storage.

The Importance of Addressing a Wine Cellar Cooling Problem Quickly

Wine Cellar Cooling

Wine Cellar Cooling Units by M&M Cellar Systems

Wines are a very sensitive type of beverage. There are many factors that can easily damage wine. One of wine’s worst enemies is heat. Wine easily loses its quality when exposed to too much heat. This is the reason wine bottles are generally dark tinted: to protect wines from exposure to light, which produces heat.

If a residential custom wine cellar cooling unit is not functioning properly, the wine collection is at risk of being damaged. The risk increases the longer the problem fails to be dealt with. This is why it is imperative that, once a problem is noticed in the wine cellar cooling unit’s ability to cool the wine storage room, immediate action should be taken.

Regular maintenance and servicing is important, so that you can identify problems with the wine cellar cooling unit immediately, and, consequently, you can have it fixed quickly. The faster the problem is solved, the safer your wines are. Never allow your wine collection to be in a place where the ideal wine storage temperature and humidity are not provided.

Wine Cellar Cooling Maintenance Los Angeles by M&M Wine Cellar Cooling

A wine cellar refrigeration system is a crucial component of cellaring wines.  The cooling unit is responsible for keeping temperature levels between 50°F and 55°F, and the relative humidity at around 60%.  Maintaining a stable and consistent storage environment is essential to preserving and improving the quality of wines for a prolonged period of time.

Types of Wine Cellar Cooling Systems

Self-Contained Wine Cellar Cooling System

Self-Contained Wine Cellar Cooling System

Wine cellar climate control systems are used in both residential wine rooms and commercial wine displays.  There are three different types of residential and commercial wine cellar cooling units on the market: self-contained “through the wall” systems, split cooling systems, and self-contained ducted units.  Each refrigeration unit has unique specifications, and requires regular preventative maintenance and service from licensed HVAC personnel.

A self-contained “through the wall” wine cellar cooling unit is the most economical and the easiest to install.  It is simply mounted on the wall, and vents through an adjacent room.  The room must be well-ventilated and should not exceed 80°F.

Split Wine Cellar Cooling System

Split Wine Cellar Cooling System

A split wine cellar cooling system houses the evaporator unit and condensing unit separately.

Separating the units provides flexibility in wine cellar cooling installation options, that can help minimize the impact of noise, heat, and vibration.  A line set is used to connect the condensing unit (placed in a remote location) to the evaporator unit (installed inside the wine room).

Ducted Self Contained Wine Cellar Cooling Unit

Ducted Self Contained Wine Cellar Cooling Unit

A self-contained ducted cooling unit provides efficient performance.  This entire cooling unit can be located within or near the wine cellar (e.g. attic, adjoining room, etc.).

Air ducts are used to supply cold air into the wine room, and return air vents pump air out of the cellar and into the system.

Since the unit can be installed outside the wine cellar, the absence of mechanical equipment inside the storage space can increase total bottle capacity, as well as add to the aesthetics.

Wine Cellar Cooling Maintenance

The absence or lack of wine cellar cooling installation can cause irreversible damage to a wine collection.  Proper support infrastructure (e.g. insulation and a vapor barrier) must also be in place to ensure that the ideal climate conditions are maintained and the refrigeration system does not overexert itself, which could otherwise lead to overheating and costly damage.

Wine Cellar Cooling Maintenance by Wine Cellar Cooling Los Angeles

Applying insulation to all walls and the ceiling helps maintain a consistent wine storage temperature.  The cool environment of a wine cellar can promote moisture migration, which can consequently lead to mold growth.  A properly installed vapor barrier prevents vapor diffusion and halts mold presence inside the wine room.

Routine wine cellar cooling maintenance and annual inspection service is highly recommended to ensure the optimum performance of climate control systems.  Proper service and maintenance conducted by a certified HVAC professional will keep the refrigeration equipment running smoothly and prevent higher cost repairs down the line.

An HVAC professional is a licensed technician that specializes in the maintenance, repair, and installation of various equipment, including commercial and residential wine cellar cooling systems, air conditioning, refrigeration, humidifiers, heating units, hermetic compressors, and intake and exhaust fans.

Preventative wine cellar cooling maintenance Los Angeles allows HVAC professionals to identify a potential problem that may lead to a major breakdown of a residential or commercial wine cellar cooling system.  Sudden failure of wine cellar climate control systems exposes wines to temperature swings that can completely ruin the overall taste and flavor of wines.

A preventative maintenance plan for commercial or residential wine cellar cooling systems provides early detection of mechanical failure.  Regular wine cellar cooling maintenance and inspection service enables a licensed HVAC professional to formulate and implement corrective measures and actions that can greatly reduce the probability of equipment malfunction and complete system breakdown.

HVAC preventative wine cellar cooling maintenance checklist includes monitoring and adjusting refrigerant levels, operation of compressor, fan motors, amperage and voltage readings, superheat and sub-cooling measurements, as well as checking electronic relays and controls, and wiring connection.  Routine inspection service of wine cellar cooling installation helps maintain the efficiency of the refrigeration equipment.

M&M Cellar Systems offer a proactive wine cellar cooling maintenance Los Angeles plan that allows their team of technicians to conduct periodic health checks to commercial or residential wine cellar cooling systems.  A general inspection of the cooling system keeps the equipment running smoothly at all times, and minimizes the risk of exposing wine collections to unfavorable climate conditions.

Wine Cellar Refrigeration Systems Los Angeles – Types to Choose From

Wine cellar refrigeration systems may be simple or complex, forced air or split-type, and affordable or expensive.  These units vary significantly on the amount of noise produced (decibel level), how they vent, installation method, and lifespan.

Generally, there are three main types of wine cellar refrigeration:

Forced Air

Through the Wall Wine Cellar Cooling System (WhisperKOOL)

Through the Wall Wine Cellar Cooling System (WhisperKOOL)

One of the three general types of wine cellar refrigeration systems Los Angeles is the forced air type, also known as the through-the-wall wine cellar cooling system.

This basic style of wine cellar refrigeration is like a window-type air conditioner, but the forced-air cooling unit cannot vent air out.

It can only vent interiorly, into an adjacent room that should be bigger than its maximum cooling capacity (80 degrees Fahrenheit).

One of the advantages of this cooling unit type is its affordable price and simple installation method.  However, a forced-air cooling unit only lasts up to 8 years, and it is quite noisy.

Ductable Wine Cellar Refrigeration Systems

Ducted Wine Cellar Refrigeration Systems

Ducted Wine Cellar Refrigeration Systems – Wine Guardian

This wine cellar refrigeration type offers high functionality.  It is somewhat similar to the forced-air type, because they both have their compressors and evaporators in a single housing.

On the other hand, a ductable unit gives you the convenience of positioning it in a separate room, far from your custom wine cellar.

You can then duct the cooled air into your wine storage room while releasing the warmed air to outside. In fact, some units can even be placed outside of your house, as long as you protect the unit from environmental factors.

Ductable wine cellar refrigeration also gives you the convenience of a quieter wine storage space, because of its lower decibel level compared to forced-air units.  It also has a longer shelf-life of up to 15 years.

With its higher functionality and lifespan, it is a bit pricey; and, on the downside, the ducts can only run a maximum of 25 feet, and you have to make sure that warm air is vented away from any living space.

Split Wine Cellar Cooling System

The third type of cooling system is the split-type.  This type has two configurations – ductless or ducted.  The former is more common, because its installation is simpler.  It is like a centralized air conditioning setup with a separate condenser that can be placed in a separate room or outside the wine cellar.

A pair of refrigeration pipes that would normally hang on your wine cellar walls connect the condenser to the evaporator.  A ducted setup, on the other hand, is ducted into the wine storage; but, this is only needed if your wine cellar is large.

Split-type units are very advantageous.  Their evaporators are very quiet, because the fans are the only parts producing a sound, and their condenser is located somewhere else.

Also, its refrigeration lines can run as long as 90 feet, giving you a wide range of installation options.  Additionally, split wine cellar refrigeration systems last up to 20 years and can give you constant temperature and relative humidity levels which allows your wines to age safely.

For its downside, a split-type unit is costly.  This is due to the fact that its refrigeration lines need to be charged with a refrigerant. You would need the HVAC expertise of a wine cellar specialist.

M&M Wine Cellar Cooling Los AngelesUltimately, a lot of factors need to be considered for your final decision.  This includes the storage room size, venting application, your budget and location, just to name a few.  Make sure that you talk to wine cellar refrigeration systems Los Angeles expert before making the final decision.
