About Wine Guardian
Wine Guardian is a world-renowned leader in precision wine cellar cooling. As an Air Innovations company, we combine the resources of a global leader in environmental control systems with a passion and expertise in wine preservation to deliver wine cellar cooling units to meet every need, from the largest commercial cellars to small cellars for wine storage at home.

OUR MISSION
Our mission is simple: to provide wine enthusiasts, collectors, and commercial establishments with professional-grade wine cellar cooling systems. We empower collectors, builders, and commercial operators to guarantee the long-term preservation of valuable wine assets, ensuring peace of mind and maximum enjoyment.

CORE VALUES
These six principles guide our work and commitment to our customers every day:
CUSTOMER FOCUS.
We view every situation from your perspective. Especially when things get tricky, we ask ourselves: “If we were the customer, how would we want this handled?”
RECOGNIZE GOOD IDEAS AND ACKNOWLEDGE SUCCESS.
We’re always looking for the good things happening, whether it’s a great new idea from our team or a successful installation you share with us. We believe in positive communication, not just problem-solving.
POSITIVELY EMBRACE CHALLENGES.
Our innovative solutions are what will forever separate us from our competitors. We embrace every challenge and look for ways to be a part of the solution.
SHARE THE DETAILS.
We believe you should always be in the loop. We take the time to share all the necessary details about your system, installation, and maintenance so you can feel confident in your wine preservation system.
MAKE QUALITY PERSONAL
We take great pride in our work. Every employee plays a role in our quality, so we double-check every step to get it right the first time.
KEEP THINGS FUN
We love what we do! While we take our engineering, assembly, and support seriously, we try not to take ourselves too seriously. We keep a light-hearted, positive perspective because wine collecting should be enjoyable.
OUR HISTORY
The story of Wine Guardian began in 1998 when our founders were looking for a better way to protect their own wine collections.
Wine Guardian was started by father-and-son entrepreneurs Larry and Mike Wetzel, who also happen to be career experts in specialty air conditioning and refrigeration. After applying their extensive HVAC knowledge to their personal wine cellars, they realized that the standard residential units on the market were noisy, cumbersome, and simply couldn’t consistently maintain the critical 55 °F temperature or provide adequate humidity control.
So they created Wine Guardian, commercial-grade cooling systems built to deliver precision and reliability previously unheard of in the industry. What began as a solution for passionate collectors has grown into a world-renowned brand trusted by homeowners and luxury establishments across the globe.
