It aligns with the typical American home — 1,800–2,200 square feet with average insulation and standard ceiling heights.

Quality Mechanical never defaults — we calculate what your specific home requires. A professional load calculation ensures the system is matched for optimal performance, efficiency, and moisture removal.
