Do I need a permit to install AC in Dunwoody?

Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect. In almost every Georgia jurisdiction a mechanical permit is required for an AC or heat pump install. Your licensed contractor pulls it, and it covers the equipment, refrigerant handling, and the electrical disconnect.

Should I repair or replace my HVAC system in Dunwoody?

If the system is under about 10–12 years old and the fault is a part — a capacitor, igniter, or motor — repair usually wins. If the compressor or heat exchanger fails, the system uses phased-out R-22 refrigerant, or it’s past 12–18 years, replacement is the smarter spend. A local Dunwoody pro can confirm which way to go on-site.

How long does an AC or furnace installation take in Dunwoody?

A like-for-like central AC or furnace swap is usually one day, so most Dunwoody jobs are completed same-day. Adding ductwork, switching system types, or a multi-zone mini-split can take two to three days.

Recommended unit for Dunwoody

High-SEER2 heat pump

Given Georgia’s hot-humid climate and mixed heating, high-seer2 heat pump is the sensible default for most Dunwoody homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

What Dunwoody code requires

Installing or replacing an HVAC system in Dunwoody follows Georgia rules under the state mechanical code. Here’s what applies statewide:

Permit
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
Required
SEER2 minimum
Federal Southeast-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
14.3 SEER2 (Southeast)
Load calculation
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
Recommended
Refrigerant
R-454B / R-32 (R-410A phased down 2025+)
Good to know
Georgia follows the IECC-based state energy code; mechanical permits and licensed-contractor installs are required, and Manual J/S sizing is recommended practice but not strictly code-enforced on changeouts.
