Load Calc Designs is a family-owned and operated HVAC design company serving builders, contractors, and homeowners across Meridian and the Treasure Valley. We specialize in new construction residential HVAC system planning, delivering the technical foundation that keeps projects moving forward. Whether you're building a model home, framing a custom home in Boise, or coordinating a subdivision in Nampa, accurate equipment sizing and duct layouts are essential to align with building plans and energy goals. Furthermore, meeting local jurisdiction requirements is critical, as Manual J, S, and D calculations are required by local municipalities to successfully secure your building permits.
