New Construction HVAC in Gwinnett County: What Builders Do Not Tell You

New construction homes should have properly installed HVAC systems — but quality varies widely. Production builders on tight margins sometimes cut corners that affect your comfort and costs for years.

The Minimum Code Problem

Building codes set minimums, not optimums. A builder can install minimum SEER equipment, minimum insulation, and minimum-standard ductwork. The result passes inspection but operates below its potential.

Common New Construction Issues

We regularly see in new Gwinnett County construction: improper sizing without load calculations, unbalanced air distribution, ductwork connections that leak from day one, and incorrect refrigerant charge.

Your First Year Inspection

Have a professional HVAC inspection done around 6 months after move-in — within your builder warranty period. Issues found can often be corrected at the builder expense.

Questions to Ask the Builder

Before closing: What SEER is the system? Was a Manual J performed? Who services the HVAC warranty? Can I see the commissioning report?

Upgrading During Construction

Upgrading to higher efficiency equipment and better duct insulation during construction costs far less than after the fact. This is the best time to make improvements.
