Key Factors to Consider Before Installation
Size and Load Requirements
Choosing the right size is critical. An undersized unit will struggle, while an oversized system wastes energy. Proper load calculations by professionals ensure perfect sizing.
Building Layout and Roof Structure
Not all roofs are created equal. Before Rooftop Unit installation, we assess the roof’s strength and structure to ensure it can safely support your new HVAC system.
