In San Marcos the outdoor condenser of a split system faces afternoon heat: the average August high is 96.8°F. CellarPro rates its 1800-series units to 95°F ambient, while WhisperKOOL rates its ceiling-mount split to 110°F, so the condenser’s rating, shade and placement are chosen with local highs in mind.
Permits for wine walls
A plug-in cooling unit and cabinetry may need no permit, but new circuits and split systems are trade work. San Marcos uses a single trade permit application for electrical, plumbing and mechanical work, and the mechanical applicant must be a state-licensed air conditioning and refrigeration contractor or exempt under state law; the Permit Requirement Determination form settles unclear cases.
