Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.
When your AC hums but won't cool, blows warm air, or keeps tripping the breaker, the fix is usually a single worn component. We test the system, find it, and replace it, often the same day. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.
HVAC trouble rarely announces itself politely. If you're dealing with any of these problems, contact our team right away for prompt help.
Low refrigerant, a failed compressor start, or a dirty condenser can all masquerade as the same symptom. Real diagnosis beats parts-swapping every time.
AC repairIf the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.
Furnace repairA system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.
Maintenance & tune-upsA system past 12 to 15 years that needs a repair every season is telling you something. We'll give you the honest math on repair versus replacement.
System replacementIf some rooms get dusty faster than others, leaky or dirty duct runs are the likely cause. We inspect, clean, and seal what we find.
Air duct cleaningWe size and mount mini-splits cleanly, proper line sets, condensate handling, and a tidy exterior finish, so they work as good as they look.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
The person at your door knows HVAC inside and out, from superheat readings to error codes, because we hire seasoned pros and keep them sharp on the methods that actually work.
If a $40 capacitor fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
Installations get the full treatment, real load calculation, correct line sets, sealed and balanced ductwork connections, and a complete commissioning test before we leave.
Year after year, Dunwoody HVAC has been the team local families call when the AC quits or the furnace goes cold. We've serviced systems in nearly every neighborhood around town, and that track record shapes how we approach each job, from the first diagnostic to the final test.
Every technician on our team is seasoned, vetted, and trained across air conditioners, furnaces, heat pumps, and ductless systems. We build every quote around your home's actual heating and cooling load. When you need help, you deserve a team that knows your neighborhood, not a national call center hundreds of miles away.
One call connects you with a nearby technician who can size up the problem and get you a quote.
Every job runs through the same proven steps, so nothing gets missed and the fix actually lasts.
Call (470) 200-3365 and we'll get you a price quote, often within a day. A few quick questions, cooling or heating, what the system is doing, how old it is, and we'll book a time that works for you.
Our technician tests the system, capacitors, motors, refrigerant charge, ignition, airflow, safeties, pinpoints the actual fault, and presents your options with clear, upfront pricing.
From swapping a contactor to setting a new condenser, every job gets the same standard: right parts, right sizing, right workmanship.
To keep your comfort reliable long-term, we can set up seasonal maintenance that cleans coils, checks the charge, and catches small issues before they strand you in the wrong season.

Acting quickly keeps a small failure from becoming a big one. Here's exactly what happens when you call Dunwoody HVAC for emergency HVAC service.
You call (470) 200-3365. A real person answers, assesses your situation, and sets up fast service for your home.
Your technician shows up ready to work, not just to look. The common failure parts ride on every truck, so the visit moves straight from diagnosis into repair.
The technician confirms exactly what failed and why, then fixes it on the spot, and if the system is beyond saving, walks you through right-sized replacement options with real numbers and a realistic timeline.
Lasting comfort is the whole point. We verify the repair, note the system's age and condition, and offer a simple seasonal plan that keeps efficiency up, breakdowns down, and miserable nights off your calendar.
"We signed up for their maintenance plan a couple of years back and it has already paid for itself. On the fall tune-up they caught a cracked igniter that would have left us with no heat in January, and replaced it on the spot. Money well spent."
"Half our house was always five degrees warmer than the thermostat said. The tech rebalanced the dampers and fixed a kinked duct run, then set up a new smart thermostat and actually taught us how to use it. Every room finally feels the same."
"Another company quoted us a full system replacement. Dunwoody HVAC found a bad blower motor in twenty minutes and repaired it on the spot. The tech said the rest of the system had years left in it. You remember honesty like that."
Your home runs on this equipment every single day. Here's why local families choose Dunwoody HVAC.
The difference shows up in the results. Our technicians have logged real years on these systems, so they identify the actual fault the first time and fix it properly instead of throwing parts at your system until something sticks.
An oversized system short-cycles itself to death; an undersized one runs nonstop and never satisfies. Our team walks you through the sizing and installs it to local code, permits included where required.
We don't wait for failures to profit from them. Every maintenance visit is thorough and documented. For hard-working systems, a spring coil cleaning is the difference between year 10 and year 15. Period.
