South Fulton HVAC Replacement: Frequently Asked Questions

How long does a full HVAC replacement take and what happens on install day?
Most standard replacements finish in one day (6–10 hours). We protect floors, recover refrigerant, remove old equipment, set the new condenser/air handler or furnace, connect line sets and drains, wire the system, pull vacuum and charge, start up, and perform commissioning checks. Before we leave, we show you how to use the thermostat and review maintenance.
Do I need a permit and inspection in South Fulton?
Yes—HVAC replacements typically require a mechanical permit and a final inspection within the City of South Fulton or Fulton County, depending on jurisdiction. We obtain the permit, schedule inspection, and provide proof of licensing and insurance.
How do you determine the right size system for my home?
We perform a Manual J load calculation (square footage, insulation, windows, orientation) and assess ducts (Manual D) to confirm airflow capacity. Proper sizing prevents short cycling, humidity issues, and high energy bills.
Heat pump vs. AC + gas furnace—what’s best in South Fulton?
Modern heat pumps are efficient year‑round; dual‑fuel (heat pump with gas furnace backup) can offer the best comfort and economics in cold snaps. We’ll compare SEER2/HSPF2 ratings, electric/gas rates, and your comfort preferences to recommend the right setup.
Are there incentives or rebates for upgrading?
Many utilities offer seasonal rebates for high‑efficiency heat pumps and smart thermostats, and federal tax credits may apply to qualifying upgrades. Availability changes—ask us to check current programs for your address. To get started, call +1 (470) 555‑0123.
