Dalton Heating & Air handles HVAC work across Dunwoody, GA, where the housing stock and weather combine to create a specific set of challenges. Most homes here were built from the 1970s through the 1990s, which means original ductwork, attic-installed air handlers, and crawlspace foundations are more common than not. Hot, humid summers push air conditioning systems hard, while spring pollen clogs coils and filters faster than in most metro Atlanta suburbs. If you need service, call (229) 537-2086 and you’ll get a live person, not a voicemail queue.
Why Dunwoody Homes Are Different
Dunwoody’s housing stock is dominated by single-family detached homes built between the 1970s and 1990s, and a lot of them still run on their original HVAC infrastructure. That means flex duct in attics, air handlers sitting in unconditioned attic space, and crawlspace foundations that hold moisture against ductwork. Our technicians regularly find collapsed or kinked ducts from original construction in neighborhoods like Dunwoody North, Georgetown, and the Perimeter area – runs that were marginal when new and have only sagged further with age. When a duct collapses in an attic, the air you’re paying to cool never reaches the far bedrooms. You get uneven temperatures and a compressor that runs longer than it should, which shortens system life.
High humidity and a long pollen season make it worse. Pollen cakes onto condenser coils and air filters in a matter of weeks during spring, so airflow drops and the system works harder. Humidity inside homes with older ductwork stays elevated because the system can’t remove enough moisture. Many Dunwoody homeowners who have renovated with high-end finishes discover that a 1990s-era system can’t hold the temperature or humidity levels that a tighter, better-insulated home demands. The fix often involves a combination of duct sealing, insulation, and properly sized equipment – not just a bigger unit.
Marco Benitez, who leads our team, puts it plainly: a system is only as good as the ductwork carrying the air. In Dunwoody, the ductwork is frequently the weak link.
Styles & brands we work with







Our Main Dunwoody Services
Three services make up the bulk of what Dunwoody homeowners call us for: AC repair through the hot months, heat pump installation when replacement makes more sense than another repair, and furnace repair when the cold snaps hit. Each has its own Dunwoody page with full detail on pricing and scope.
AC Repair in Dunwoody
When a Dunwoody AC system fails in July, the problem is often tied to the strain of long run times and – especially in spring – pollen loading on the condenser coil. We diagnose the issue, put the repair in writing, and get it fixed. Every repair we perform includes a written guarantee for a full year, and if the work fails during that window, we return at no charge. AC Repair in Dunwoody covers pricing, common failures, and what to expect on the visit.

Heat Pump Installation in Dunwoody
Heat pump installation in Dunwoody is an increasingly common choice because a modern heat pump handles both cooling and heating in one unit, which suits the climate well. The catch is that older homes with original ductwork often need duct sealing or replacement before a new heat pump will deliver its rated efficiency. We size the system to the home as it actually is, not to a rule of thumb. Heat Pump Installation in Dunwoody has the full installation process, brand options, and current pricing.

Furnace Repair in Dunwoody
Dunwoody winters are mild compared to northern states, but a failed furnace on a 30-degree night is an emergency that won’t wait. Most furnace repairs in this area are $150 – $700 depending on the part. We service gas furnaces and electric air handlers in homes across Dunwoody, always with a written price before we touch the unit and a full-year written guarantee on the repair itself. Furnace Repair in Dunwoody explains what fails most often on local systems and what repairs typically cost.

AfterPricing for HVAC Company in Dunwoody, GA
Here are the price ranges we typically see in Dunwoody, based on the work we do across the area. Your exact quote is written before any work starts, so the number you approve is the number you pay.
| Service | Typical Range in Dunwoody |
|---|---|
| AC repair (minor: capacitor, contactor) | $150 – $350 |
| AC repair (major: compressor, evaporator coil) | $450 – $650 |
| Furnace repair (minor: ignitor, flame sensor, limit switch) | $150 – $300 |
| Furnace repair (major: blower motor, gas valve, control board) | $400 – $700 |

| AC installation (high-efficiency two-stage, 17+ SEER) | $5,500 – $7,500 |
| Tune-up / seasonal maintenance | $80 – $200 |
What pushes a Dunwoody repair toward the higher end of the range is usually access: units located in tight attics or on second-story platforms take more time to work on. Duct issues discovered during an installation can also add to the final figure, which is why we include a duct inspection in every new system quote. Whatever the number ends up being, you’ll get it in writing before we begin. That’s part of The Garrison Standard – the operating code every Dalton Heating & Air location is bound to.
