HVAC in Georgia: the five-ton license ceiling and a split fuel market

Why does the Georgia license ceiling matter to a homeowner?

Because Georgia draws the line inside the residential range. In most states the consumer-facing license classes divide residential from commercial.

Source fact: O.C.G.A. § 43-14-6(a)(1) provides in full: “Class I licenses shall be restricted to the installation, repair, or service of conditioned air systems or equipment not exceeding 175,000 BTU (net) of heating and five tons (60,000 BTU) of cooling. Class II licenses shall be unrestricted.”

HYRE HVAC Research Desk analysis: Compare that with the other states this site covers. Florida’s Class B air-conditioning contractor is limited to 25 tons of cooling; Texas’s Class B license to 25 tons; North Carolina’s heating group three to 15 tons.

All three ceilings sit far above anything a house needs, so in those states the class is a formality for residential work. Georgia’s Class I ceiling is five tons — 60,000 Btu of cooling, together with 175,000 Btu (net) of heating.

A three-ton system is a common Georgia house; a five-ton system is a large or leaky one; and above five tons the Class I holder is outside the statute.

What follows for a homeowner: If a load calculation puts your house at or above five tons of cooling, the license class of whoever installs it stops being a box-ticking detail.

And there is an incentive worth naming: a contractor whose license caps at five tons has a reason, conscious or not, to arrive at a load calculation that lands just under it.

Undersizing is not the usual failure mode in the South — oversizing is — but this is the one structural reason a Georgia quote might tend the other way, and it is why the calculated tonnage and the license class are worth asking about together.

The useful next step: Ask for two numbers: the Manual J calculated cooling load in tons, and the license class held by the company and by the qualifying agent on the license. Both are ordinary questions with ordinary answers. A Class II license is, in the statute’s own word, “unrestricted”.

Does Georgia heat with gas or electricity?

Both, almost equally. Source fact: In EIA’s Residential Energy Consumption Survey 2020, 46.6% of Georgia households heat with natural gas (46.6% ± 2.9 percentage points) and 45.5% with electricity (45.5% ± 2.9). 27.3% have a heat pump, against 13.9% nationally, and 95.2% have air conditioning.

HYRE calculation: Those two heating shares are 1.1 percentage points apart, against a combined standard error of about 4.0 points. On the survey’s own error bars we cannot say which fuel leads in Georgia. That is unusual: most states are decisively one or the other — Florida is 61 points apart, Ohio about 41.

Source fact: The climate says the same thing. NOAA’s 1991–2020 county normals give a Georgia median of 2,094 cooling degree days and 2,315 heating — as close to balanced as any state we cover.

The range across 159 counties, second only to Texas in number, runs from 2,668 cooling degree days in Camden County to 820 in Union County, which records 4,056 heating degree days — more than any county in Florida or south Georgia by a wide margin.

HYRE analysis: A genuinely balanced climate is the hardest case for equipment selection, and it is why Georgia is one of the states where the dual-fuel argument is strongest: a heat pump doing the shoulder seasons with a gas furnace behind it for the coldest hours.

In Florida that is over-engineering; in Ohio the heat pump half struggles to pay; Georgia is the middle where both halves earn their keep.

Whether it is right for you turns on whether you already have a gas line, because the capital cost of adding one rarely comes back.

What does it cost to run, and which federal rule applies?

A heat pump heats for about $272 a year against $365 for gas, and the DOE Southeast rule applies.

Source fact: EIA’s 2024 residential averages for Georgia are 14.08 cents per kilowatt-hour — 35th of 51 jurisdictions — and $18.19 per thousand cubic feet of natural gas, a ratio of 2.35 to one against 3.45 nationally.

HYRE calculation: Applying the south census-region consumption averages from RECS 2020 Table CE3.1: a 95% gas furnace costs about $365 a year to run, a heat pump at a seasonal COP of 3.0 about $272, and cooling about $466.

The breakeven seasonal COP is 2.24, comfortably clear of any modern system, and Georgia ranks 7 of 51 on our Heat Pump Readiness Index.

Source fact: Under 10 CFR § 430.32(c)(6) Georgia is in the DOE Southeast region: a split-system air conditioner installed here since January 1, 2023 must reach 14.3 SEER2 below 45,000 Btu/hr and 13.8 SEER2 above it, against 13.4 nationally, with no additional EER2 requirement.

The restriction attaches to the installation: “Any model of outdoor unit that has a certified combination with a rating below the applicable standard level(s) for a region cannot be installed in that region.”

And the correction that matters most: the regional standard reaches air conditioners only. Heat pumps carry no regional installation standard anywhere in the country — our study of the regional split reads that out of the full CFR text.

Source fact: Georgia’s energy code is recorded by the Department of Energy’s Building Energy Codes Program as 2015 IECC with Amendments for residential buildings, effective January 1, 2020, and 2015 IECC and ASHRAE 90.1-2013 with amendments for commercial.

HYRE analysis: That baseline is a decade behind Florida’s and two editions behind California’s, so a Georgia code-minimum installation is a 2015 model-code minimum.

In a state with 2,018 cooling degree days and ducts commonly run through unconditioned attics, duct sealing and insulation are the specifications most worth paying to exceed.

What can we tell you about Georgia contractors?

Nothing verifiable yet, and that is worth saying plainly.

HyreHVAC publishes no verified contractor count for Georgia. The Georgia Secretary of State’s Professional Licensing Boards register — the Division of Conditioned Air Contractors, under the State Construction Industry Licensing Board — was unreachable when our store attempted it, so no Georgia record carries an issuing authority, a register URL or a retrieval date.

We hold records we cannot stand behind on a named register with a retrieval date, and the rule on this site is that such records are not counted, not ranked and not published as a roster.

That is a limitation of our store, not a statement about any Georgia contractor.

Why we are not printing a number: We do hold Georgia rows. Printing their count here would state, by implication, that they were checked against a register — and they were not.

Our licensing study was rewritten in September 2026 for exactly this reason after a different state’s records were found to be counted as verified while carrying no provenance.

A count is a claim about evidence, not just a number, and we would rather publish a shorter page than a bigger figure.

What to do instead: Georgia’s licensing board publishes its own public verification service, and it is the authoritative source in a way our store is not.

Look up the company yourself, confirm the license is active, and read the class off the record — Class I or Class II, which after the first section of this page you now have a specific reason to care about.

The standing rule on this site: Every national claim we publish rests on federal or state agency data — EIA, NOAA, the Code of Federal Regulations — and never on our own contractor counts. Georgia is the clearest illustration of why that rule exists.
