HVAC Company in Peachtree Corners, GA

Southeast Heating & Cooling is an independent, family-owned, Buford-based HVAC company serving Peachtree Corners homeowners job by job. We repair, replace and maintain all major brands, we're licensed in Georgia (CR110452), and we're honest about scheduling.

What kind of HVAC company is Southeast for a Peachtree Corners home?

A small one, on purpose. Southeast was founded in 2022 and is owned by Phillip Suggs and Brian Malone, and it's still family owned and locally owned. We focus on residential heating and air, we install Daikin as our primary brand, and we service everything else that's a major brand. We're a Daikin Premier Dealer. We're not a multi-trade chain, and we don't have a Peachtree Corners branch; Our only office is 4582 Atwater Ct STE 8, Buford, GA 30518.

For Peachtree Corners, that matters in two directions. You get a company where the owners' names are on the business and the same team answers the phone and does the work. You also get a company that's driving out from Buford to reach you, at the edge of the area we normally cover, which is why we call Peachtree Corners an edge market and handle it job by job.

Will Southeast take my Peachtree Corners job?

Usually, yes. Here's how we decide, so there's no mystery.

• The job type. Residential repair, replacement, installation and maintenance all fit. Selected light-commercial work fits only when it's a scale we can do well. Large commercial or industrial HVAC, commercial refrigeration, new-construction projects, window units, geothermal, boilers, oil furnaces and mobile-home equipment don't fit, and we'll say so instead of wasting your afternoon.
• The day's capacity. We aim to respond within 24 hours and try to answer calls 24/7, but arrival depends on demand, weather, location and the problem. In a July heat wave or a January cold snap, a planned job in Peachtree Corners is easy to schedule and an urgent one depends on where the trucks already are.
• Whether we can do it right in one visit. The more you tell us up front, the better the odds. Brand, system type, where the equipment is, what it's doing.

When our office calls or texts to confirm, the appointment is real. Until then it's a request, and we'd rather turn down a job than confirm one we can't keep.

What should you check before hiring any HVAC company?

Ask these of everyone you call, including us. Our answers:

• Are you licensed in Georgia? Yes, license CR110452.
• Who owns the company? Phillip Suggs and Brian Malone, locally.
• What do your reviews say? A 5.0 Google rating across 979 five-star reviews as of September 2026.
• How do you size a new system? With a Manual J load calculation, the industry method for matching the equipment to the house, on every replacement. Not by copying the old unit's size.
• Who pulls the permit and registers the warranty? We do, when a permit is required, and we register the manufacturer warranty for you.
• What's your labor warranty? Written by tier: 1 year on single-stage, 3 years on two-stage, 5 years on Daikin Fit variable-speed systems.
• What if something's wrong with the work? If a problem is caused by our workmanship, Southeast will return and correct it at no charge.

Any company that gets vague on the license, the permit or the warranty is telling you something.

What does Southeast do in Peachtree Corners homes?

Repair. A $79 diagnostic finds the real cause; the technician shows you the part and quotes the fix before starting. Details on HVAC repair, and the local pages for AC repair and furnace repair in Peachtree Corners.

Replacement. A free in-home estimate, a Manual J, and written options across single-stage, two-stage and Daikin Fit. Every new Daikin system we install uses R-32 refrigerant. See HVAC replacement.

Maintenance. A $49 seasonal tune-up while the promotion is active, or the Southeast Family Plan for two visits a year. Our HVAC maintenance page shows what a visit covers. Because Peachtree Corners is an edge market, the Family Plan's priority scheduling is worth more here than it is next door to our office.

What does it cost, and how does financing work?

We don't publish repair totals or system prices online because every home is different. What we do publish: the $79 diagnostic, a free replacement estimate, and up to $1,000 off a new system (some restrictions may apply). Financing is through Service Finance: 18 months at 0% interest, 12 months with no payments and no interest, or 180 months at 9.99%, with payment examples from $59 a month for heating, $69 for AC and $99 for a complete system, with credit approval; see financing terms.

The Southeast Family Plan is $149 a year for the first system and $109 for each additional one: two visits, standard 1-inch pleated filters, 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 it, and it transfers to a new homeowner.

How do I get started?
