Clermont's climate zone, in plain terms
Clermont falls in IECC climate zone 2A, and ENERGY STAR separately groups Lake County into its Southern zone for window certification.

A Orlando-Kissimmee-Sanford, FL contractor who can't name either one on request is worth a second question before you sign.
