HVAC Company in Jefferson, GA

Southeast Heating & Cooling is a family-owned, Buford-based HVAC company that takes residential repair, replacement and maintenance jobs in Jefferson, GA when the job and our capacity line up. Here's how to tell whether we're the right fit.

Is Southeast the right HVAC company for your Jefferson home?

Jefferson is a right-job market for us. We're a good fit when three things are true:

• You own the home, or you're a renter with the owner's authorization to approve work.
• The equipment is residential. Central air conditioners, gas furnaces, heat pumps and ductless mini-splits of any major brand. We don't service window units, geothermal systems, boilers, oil furnaces, mobile-home equipment or commercial units, and we don't do new construction.
• The job can be scheduled honestly. Planned work like a replacement estimate, an installation or a maintenance visit fits easily. An urgent repair fits when the day's capacity allows, and our office will tell you before you wait.

We're not the right fit if you need a same-day guarantee. We don't give one to anyone. We try to answer calls 24/7 and aim to respond within 24 hours, and arrival depends on demand, weather, location and the type of problem.

What should you tell us when you call from Jefferson?

The more we know up front, the straighter our answer on timing. Have these ready:

1. Your name, mobile number and the service address or ZIP. Say it's Jefferson so we check the right part of the schedule.
2. The type of system (central AC, gas furnace, heat pump, mini-split) and its approximate age if you know it.
3. What it's doing: no cooling, no heat, tripping the breaker, water, a noise, an error code.
4. How urgent it is. A system that's completely down in extreme weather is a call, not an online booking, so a person can triage it.
5. For a replacement estimate: how many systems you have and whether you're interested in financing.

That information lets the office judge the fit, send the technician most likely to have the right parts on the truck, and confirm a realistic window by call or text. A request isn't an appointment until we've confirmed it.

What does Southeast stand behind?

Southeast is independent, family owned and locally owned, founded in 2022, owned by Phillip Suggs and Brian Malone. We hold Georgia license CR110452 and a 5.0 Google rating across 979 five-star reviews as of September 2026. On new systems, our labor warranty runs one year on single-stage equipment, three years on two-stage and five years on Daikin Fit variable-speed. Qualifying Daikin Fit equipment carries 12-year parts and up to 12-year unit replacement, and qualifying single-stage equipment carries 12-year parts and 6-year unit replacement, both subject to Daikin's terms. We register the manufacturer warranty for you and pull the required permits. And on any job: if a problem is caused by our workmanship, Southeast will return and correct it at no charge. Our guide to HVAC warranties explained shows how labor and manufacturer coverage fit together.

How do repair, replacement and maintenance work from Buford?

Repair starts with a $79 diagnostic, typically charged. The technician finds the actual cause, explains it plainly and quotes the fix before touching anything. The full process is on HVAC repair; the Jefferson-specific version for cooling is AC repair in Jefferson.

Replacement starts with a free in-home estimate and a Manual J load calculation, the industry method for sizing the system to your house instead of copying the old label. Daikin is our primary brand, we're a Daikin Premier Dealer, and every new Daikin system we install uses R-32 refrigerant. See HVAC replacement, or furnace installation in Jefferson for a heating-side example.

Maintenance is a $49 seasonal tune-up while the promotion is active, or the Southeast Family Plan for two scheduled visits a year. Because plan visits are booked ahead, they're some of the easiest Jefferson work for us to fit. Our HVAC maintenance page lists what a visit includes.

What does it cost to hire Southeast in Jefferson?

Every home is different, so we don't publish repair totals or system prices. What we do publish: the $79 diagnostic; the free replacement estimate; up to $1,000 off a new system, some restrictions may apply; and the Southeast Family Plan at $149 a year for the first system and $109 for each additional system, with two visits, standard 1-inch pleated filters, condensate drain and condenser-coil cleaning, 15% off qualifying repairs, priority service and no after-hours charge for members. More than 1,000 members are on the plan, and it transfers to a new homeowner.

Financing is through Service Finance: 18 months at 0% interest, 12 months with no payments and no interest, or 180 months at 9.99%. Payment examples run from $59 a month for heating, $69 for AC and $99 for a complete system, with credit approval; see financing terms.
