Just outstanding customer service, it makes such a difference! I worked with a customer service representative (Sergio) who was available (and showed great patience) in answering all my questions to insure I got the right unit for my cellar. Many thanks!

Communication
Communication. The exchange from the answering the phone, parts department, my technician and myself went very smoothly. Everyone at WhisperKOOL was professional and knowledgeable about the old wine cabinet. Part’s ordering and shipping instructions again went smoothly.
When parts arrived , perfect fit and performance. The 25 year old Vinotheque Cabinet wine cooler is running like new.
Thank you WhisperKOOL 😊

WhisperKOOL are immoral
Installed their cellarcool 2200 product. It never worked - for their own agent around to inspect and they said compressor was faulty. And then to get them to honor the warranty - hoop after hoop after hoop. Even their agent said it was ridiculous in an email to them. Eventually they said they’d honor the warranty if I sent them the unit and $1500 which they’d return with a new unit if they didn’t find anything untoward in returned machine. I said…..that sounds like you will as you seem to have been looking for every reason under the sun to not honor it. So they won….as I left it at that and moved to a new product. They are immoral and their products are bad.

Questioning the quality of the Whisperkool Slimline series
I have owned 2 Whisperkool units - the 1st (Slimline 2500) cooled my cellar for 6 ½ yrs then it died. The 2nd, (Slimline LS) cooled my cellar for 3 ½ yrs then died. The Slimline LS died a few weeks ago. My cellar is 105 cf , Whisperkool currently advertises the LS to cool approximately 300 – 650 cf. My cellar is 100% interior in my house, built inside a closet. There are no exterior walls to it. It draws air that always ranges between 68 - 72 degrees. When I converted the closet to a cellar, I insulated all the walls and ceiling with traditional home insulation made to go between 2x4 studs. The floor is concrete. It has a solid wood door that is sealed on all 4 door jams and it has a rubber weather seal on the bottom. Inside the cellar are traditional wine racks that hold about 180 bottles, all open to the interior space. There are no glass enclosures or structures in the cellar. I inspected both units ongoing and the filter cleaned regularly.
After the 2nd cooling unit failed, I started questioning the quality of Whisperkool. An average of a 5 yr life does not make sense to me. My refrigerator, AC unit and freezer all last significantly longer. Why doesn’t my Whisperkool last. In researching this question, I learned that shorter life cycles for wine chilling units suggest poor maintenance and/or lower quality equipment. As stated above, I did ongoing maintenance!!!
The tech group at Wine Cellar HQ (where I purchase the LS) took me through a Q&A process recently with the objective of trying to troubleshoot. Through multiple emails and sending them a few pictures of my cellar, they determined the problem likely to be insulation and my cellar door. This conclusion did not seem logical so I had a general contractor come to my house. This guy, having 30+ yrs experience, was very surprised to hear my issues were related to insulation and my door. I am now at a crossroads as what to do next inside my cellar. My wife and I really enjoy our red wine and we desire to properly care for it.

I purchased a Whisperkool SC Pro 4000…
I purchased a Whisperkool SC Pro 4000 wine cooler and have been extremely disappointed with the noise level performance of the unit. Whisperkool represents that the unit operates at 50-55 dBA and they have actually produced a youtube video showing the unit running at 52.7 dBA. As it turns out the unit actual runs at 60-70 dBA, up to 50% louder than what the manufacturer has stated. I’ve had multiple interactions with the manufacturer, just to be told, sorry it is what it is. These units cost approx. $3500 which is quite an investment to be told, yes we lied about the units performance but thank you for the money. Beware of WhisperKool.

Bought a brand new CellarCool CX4400
Bought a brand new CellarCool CX4400. 4 months in, the unit stopped cooling. Provided numerous pictures and information to the company for warranty purposes. It was installed correctly and plenty of air flow. They claim it was not and denied warranty. Very very sneaky, the unit clearly was defective. I wont be doing business with any of this brands companies ever again.
