I help homeowners, contractors, and builders with residential HVAC design calculations and permit documentation. My services cover Manual J heating and cooling load calculations, Manual S equipment selection and sizing, and Manual D duct design. Whether you're planning a new home or preparing documents for a building permit, I focus on clear calculations, organized reports, and project-specific requirements. To get started, share your floor plans, building location, property details, and permit requirements so the scope can be established before work begins.
