Dunwoody’s 1970s and 1980s colonials and brick-front traditionals were built well, but their original HVAC systems were sized for a different Georgia summer. Pair that with homeowner association rules about equipment placement and screening, and the job is rarely as simple as swapping a part. We know that before we roll up. The price is in writing before any work starts, and every repair carries a written one-year guarantee under the 365-Day Done Right Promise. If the fix fails inside that window, we return at no charge.

We run AC Repair calls across Dunwoody every day, from Mount Vernon Road to the neighborhoods off Chamblee Dunwoody Road. Our techs understand the load variables created by mature tree canopy, the pollen that cakes condenser coils in April, and the static pressure problems baked into original ductwork. This isn’t a one-size-fits-all service call.

Why Dalton Heating & Air Sandy Springs Is Dunwoody’s Preferred AC Repair Company

Dunwoody homeowners call us because we operate under the Garrison Standard, and that means something specific. Since 2003, Garrison Partners locations have been held to the Garrison Code: arrive inside the stated window, put the price in writing before starting, do the job by the book, leave the site clean, and stand behind the work for a full year. No exceptions, no fine print.

Every technician who arrives at your Dunwoody door is background-checked and uniformed. You’ll know who is coming before they arrive. They are factory-trained to diagnose and repair nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters here, because Dunwoody has a lot of original 1980s Carrier and Trane equipment still in service, and those systems have known failure points that a less experienced tech will miss.

Our Dunwoody customers also get something that has become rare in this trade: a written price before any work begins. Not an estimate range, not a ballpark. A line-item price, on paper, that does not change at the door. Marco Benitez runs our location with that discipline on every single job.

AC Not Blowing Cold Air in Dunwoody

AC Not Blowing Cold Air in Dunwoody usually comes down to one of four faults we see week after week: a refrigerant charge that has leaked down over time, a failed capacitor that cannot start the compressor, a condenser coil packed with pollen and pinestraw from the tree canopy, or a blower motor straining against undersized ductwork. A typical diagnostic and repair runs $150 – $650 depending on which part failed. In the Georgetown area especially, we find original 1980s systems where the refrigerant is fine but the upstairs returns are too small, so the system can never deliver cold air where it’s needed.

We got a call from a homeowner in the Georgetown area whose upstairs bedrooms were running 8 degrees hotter than the rest of the house. Our tech found the original 1980s Trane still holding a refrigerant charge but paired with a badly undersized return in the hallway. Static pressure was double what the blower motor was rated for. We resized the return, sealed the duct collars in the crawlspace, and replaced a weak capacitor on the condenser coil. Now the second floor stays within 2 degrees of the thermostat setting. That’s the difference between guessing and measuring.

Refrigerant Recharge

A refrigerant recharge means topping off the cooling fluid your system needs to reach set temperature. If your Dunwoody AC is running but the air from the vents is lukewarm, low refrigerant is the most common cause. We locate the leak before we recharge, because putting refrigerant into a system that’s still leaking is throwing money away. Recharges in Dunwoody typically fall in the $200 – $450 range depending on how much refrigerant the system needs.

Capacitor Replacement

The capacitor is the electrical component that gives your compressor and fan motor the jolt they need to start. In Dunwoody’s humid summers, capacitors fail more often because heat and moisture break down the dielectric material inside. A capacitor replacement runs $150 – $300 and is usually a same-visit fix. We carry common capacitor ratings on the truck for the brands most common in Dunwoody homes.

AC Maintenance in Dunwoody

AC Maintenance in Dunwoody is not optional, not if you want a system to survive this climate. High humidity, heavy pollen, and mature hardwood canopies mean coils foul faster here than in most of metro Atlanta. A tune-up runs $80 – $200 and includes a written report of what was actually found: refrigerant levels, capacitor health, static pressure, coil condition, and drain line flow. Our techs are not paid on what they sell, so the report tells you what needs attention and what does not.

Dunwoody’s HOA requirements add another layer. If your outdoor unit must be screened by landscaping, those shrubs shed leaves and debris straight into the condenser coil. That blocks airflow, raises head pressure, and shortens compressor life. A spring tune-up after pollen season, and a fall check after leaf drop, catches most of that before it becomes a $600 repair.

Pre-Season Tune-Up

We recommend Dunwoody homeowners schedule a tune-up in March or April, before the first real heat wave. That gives us time to catch weak capacitors, clogged drain lines, and pollen-packed coils before they strand you on a 95-degree Saturday. The flat price includes cleaning the condenser coil, checking the refrigerant charge, testing the capacitor, and flushing the drain line.

Post-Repair System Check

Every repair we complete in Dunwoody includes a full system check before our tech leaves. We measure temperature drop across the coil, check amperage on the compressor and fan motor, and verify the condensate drain is flowing. If something else is about to fail, we tell you then, in writing, with a price. Not a future surprise.

Trusted Brands We Service in Dunwoody

Our techs are factory-trained on Rheem, York, Daikin, Bryant, and five other major residential lines, so the name on the cabinet doesn’t matter. What matters is that the parts for Dunwoody’s older stock are actually available. We keep common capacitors, contactors, fan motors, and relays stocked on our trucks for the brands most often installed in this area’s 1970s-1990s homes. That means fewer return trips and faster turnaround when your AC goes down on a hot Dunwoody afternoon.

Common AC Repair Problems We See in Dunwoody Homes

• Condenser coils packed with pollen and pinestraw. The mature tree canopy that makes Dunwoody beautiful also sheds constantly into outdoor units. A packed coil starves the system of airflow and trips the high-pressure switch, which shuts the compressor down.
• HOA screening shrubs growing too close to the unit. Many Dunwoody covenants require landscaping around outdoor equipment, but when those shrubs grow within a foot of the coil, they block the manufacturer’s required clearance. The compressor overheats, and the system fails early.
• Original 1970s ductwork separating in crawlspaces. In slab and crawlspace homes, the original duct seams have often opened up over decades. The AC runs constantly but the upstairs stays hot. We check static pressure on nearly every Dunwoody call where the complaint is uneven cooling.
• Undersized returns in upstairs bedrooms. The colonials near the Georgetown area commonly have original Carrier and Trane units paired with returns too small for the blower. The result is chronic hot spots that no thermostat adjustment can fix.
