New home construction with HVAC ductwork installation

Building Right from the Start

New Construction HVAC

HVAC Systems Designed for New Builds

Getting the HVAC system right during new construction is one of the most important decisions a builder or homeowner can make. A.C. Simpson & Associates LLC partners with contractors and homeowners throughout Senoia, GA and surrounding areas to design, size, and install complete HVAC systems that deliver efficient, reliable comfort from day one.

We work directly from blueprints to perform Manual J load calculations, select appropriately sized equipment, and coordinate ductwork installation with your construction timeline. Our goal is a system that performs efficiently for decades — not just one that passes inspection.

  • Full ductwork design, fabrication, and installation
  • Coordination with builders and general contractors
  • Energy-efficient system selection to meet code requirements

Frequently Asked Questions

When should I bring in an HVAC contractor during new construction?

Ideally before framing is complete. Early involvement allows us to plan ductwork routing, equipment placement, and penetrations without costly modifications later.

How do you determine the right size system for a new home?

We perform a Manual J load calculation that accounts for square footage, insulation levels, window placement, ceiling height, and local climate data to select the correctly sized equipment.

Do you work with custom home builders?

Yes. We regularly partner with custom home builders and can accommodate unique architectural designs, multi-zone systems, and high-efficiency equipment specifications.
