A control system for maintaining the temperature and humidity for a wine storage area within a predetermined range and at low operating cost includes a conduit field buried in a sand layer at a depth where the temperature normally ranges from 55 to 57 degrees F. An air intake is preferably disposed on a north side of a new or existing structure and draws outside ambient air into the conduit field when an exhaust fan is on and a partial vacuum is created in the wine storage area. The temperature and humidity of the ambient air are altered, as desired, during its passage through the conduit field until it is discharged in the wine storage area as a conditioned air. A pair of thermostats each individually control operation of the exhaust fan so as to maintain temperature below a first maximum setting and above a second minimum setting.
