Erza WordPress Theme is a feature-rich HVAC Services WordPress theme built on Bootstrap 5, fully compatible with WordPress 6.x with full WooCommerce integration. It ships with 12 page templates, a filterable AC unit gallery, a full e-commerce module with cart and checkout, a blog module — all controlled from the WordPress admin and Customizer with zero coding required.

Built for WordPress developers, freelancers, and site owners delivering HVAC and air conditioning service websites. The theme follows WordPress coding standards throughout: template hierarchy, action and filter hooks, wp_enqueue_scripts for all assets, and a child-theme-ready structure. Every visible element is customisable via the Customizer live preview — no page builder plugin dependency required.
