1 What stands out in Georgia for an HVAC contractor What is this?

The things people get wrong or do not expect about Georgia, in a few sentences.

Georgia calls the trade "conditioned air contracting". A Class I license stops at 175,000 BTU of heating and 60,000 BTU of cooling (5 tons), and each complete system in one installation counts as its own job for that limit.
EPA Section 608 certification is written into the state experience rule. You must show it in your license application, not just carry it on the job.
Since December 1, 2021, every conditioned air company must show its registration number as "GA. REG. CN-" plus the qualifying licensee's number on both sides of every work truck in letters at least 2 inches high, in ads, and on every invoice and proposal. Plumbers have no such rule.
HVAC licenses renew by November 30 of odd-numbered years. Plumbing licenses renew in even years. A person who holds both renews in different years.
The board rules, the conditioned air FAQ, and the licensing law do not ask for liability insurance or a bond to hold the license. Several websites say otherwise, and no official source gives a figure.
A central furnace or air handler is part of the building for sales tax. You pay tax when you buy it and charge the customer none. A window unit stays personal property. You buy it for resale and charge the customer tax on it. Labor is tax-free only when it is its own line on the invoice.

4 How much insurance does an HVAC contractor need in Georgia? What is this?

What Georgia requires you to carry before you work.

Minimum liability insurance	Not listed yet
Type of policy	None found. The board rules (Department 121), the conditioned air FAQ, and O.C.G.A. 43-14-8 do not ask for liability insurance to get or keep the license or to register the company.
Who this applies to	Not applicable at state level. Cities and counties may ask for a certificate before they issue permits, and most customers and builders will ask for it.
Who must be named on the certificate	Not applicable
Why other websites say a different number	Several non-government websites say Georgia conditioned air contractors must carry general liability insurance. We could not find that in any official source read for this record. The business registration form on sos.ga.gov may ask for it. Check with the board before publishing.
Workers' comp required?	Yes, once you regularly employ three or more people, full time or part time
Who can opt out	If your company is a corporation or LLC, officers and members count toward the three even if they opt out. Up to five officers or members can opt themselves out by filing Form WC-10 with their insurance company. A sole proprietor or partner is treated as an employer, not an employee, and is not covered unless they ask the insurer in writing. No state fee for the WC-10 was listed.
Workers' comp: if you skip it	Civil penalties of $500 to $5,000 per occurrence for failing to carry coverage, and possible criminal charges

Cities may also ask for a bond before they let you pull permits, so check with your city.

9 Does an HVAC contractor charge sales tax on labor in Georgia? What is this?

In Georgia, no sales tax on repair or installation labor if you list it as a separate line on the invoice. If you lump labor and parts into one price, the whole amount can be taxed. The rest of the rules are below.

See how this compares in every state: Sales tax on labor for plumbers and HVAC contractors by state

Central systems and furnaces	Count as part of the building. You pay sales tax when you buy the unit, ductwork, and parts, and you charge the customer no tax on them. You cannot buy them tax-free with a resale certificate.
Window and portable units	Anything held in place only by gravity or a plug stays personal property after you install it. You can buy it tax-free for resale (Form ST-5) and must charge the customer sales tax on the price of the unit. Installation labor on it is still tax-free if listed separately.
Labor	No sales tax on repair or installation labor if you list it as a separate line on the invoice. If you lump labor and parts into one price, the whole amount can be taxed.
Homes versus businesses	No difference. Georgia looks at whether the item becomes part of the building, not at what kind of building it is.
New buildings versus repairs	No difference for parts that become part of the building. You pay tax when you buy them either way.
Registering and filing	Every contractor must register for a sales and use tax number in the Georgia Tax Center and file a return every month, even in months with no sales.
Use tax	If you buy equipment where the rate is lower than the rate where the job is, you owe the difference as use tax. If you paid more, there is no refund.
Tax rate	4 percent state, plus local rates. Most counties total 7 to 9 percent.

Who has to send a notice	Anyone who was not hired by the general contractor directly, such as a sub of a sub or an equipment supplier, and only when a Notice of Commencement (a form the owner or contractor files with the county superior court clerk at the start of a job) was filed.
