Get your free estimateFast, Reliable AC Repair Across Roswell
When your air conditioning quits during a Roswell summer, you need someone who understands what your house is up against. That means 95-degree afternoons with humidity thick enough to fog your windows, pollen coating every outdoor unit by late April, and homes built anywhere from 1880 to 2005. Our AC Repair team answers the phone with a live person around the clock, sends you the technician’s name and photo before arrival, and puts a written price in your hand before any wrench turns. If you’re in Roswell and the air won’t cool, call (478) 662-5175 and we’ll walk you through what’s happening, what it’ll cost, and when we can be there.
Why Brandt HVAC Co Marietta Is Roswell’s Preferred AC Repair Company
Roswell homeowners call us because we treat a repair call like a diagnosis, not a sales visit. We don’t get paid on what we sell, so when a technician tells you a capacitor is shot, that’s what it is. Devin Marlowe built this company on the Threshold Verified standard: every tech is background-checked, identity-verified, uniformed, and introduced to you by name and photo before they ever ring your doorbell. When someone arrives, they show a photo ID badge at the door. If anyone shows up who you were not told to expect, that visit is on us. We make it right.
Our crews know Roswell streets, not just Roswell zip codes. We know that a 1960s ranch off Old Alabama Road has different electrical realities than a 1990s cul-de-sac near Crabapple. We know that homes along the Chattahoochee corridor battle humidity differently than houses up near the Cherokee County line. And we know that a blower motor failing in a 1980s subdivision east of GA-400 usually isn’t a motor problem at all. It’s static pressure from undersized ductwork. That’s the kind of local knowledge that keeps a repair from repeating itself in two summers.
Every repair we complete in Roswell includes a written guarantee that states exactly what’s covered and for how long. If that repair fails within the guarantee period, we return free of charge under the 365-Day Done Right Promise. No argument, no second invoice.
Styles & brands we work with







AC Service in Roswell
AC Service in Roswell means more than swapping a part and driving off. It means checking how the whole system behaves under Georgia’s heat and humidity load, because a repair that ignores airflow, refrigerant charge, and coil condition is a repair you’ll pay for twice. A full AC service visit for a typical Roswell home runs $150 – $650 depending on what we find inside the cabinet and at the condenser. You get a written price before we start, and a written guarantee when we finish.
Diagnostic and Repair Checks
We start with what’s actually failing, not what’s easiest to replace. In Roswell, that often means a pitted contactor, a swollen capacitor, or a condenser coil packed with cottonwood fuzz from April. We test, we show you what we found, and we quote a fixed number before touching anything.
Coil Cleaning and System Evaluation
A clogged evaporator coil can drop your cooling capacity by 30% or more, and in a humid Roswell summer that’s the difference between a dry house and a damp one. We clean coils, check refrigerant lines for leaks, and take a static pressure reading on the blower when the system has a history of failures. Evaporator coil cleaning with a static pressure check runs $150 – $350.
AC Unit Repair in Roswell
AC Unit Repair in Roswell covers the mechanical and electrical failures that stop a condenser or air handler from doing its job: bad capacitors, failed fan motors, contactors, refrigerant leaks, compressor issues, and thermostat wiring faults. Most Roswell repair calls land in the $150 – $650 range, parts and labor included, and we tell you the exact number after diagnosis, before we order a single part.
Capacitor, Contactor, and Fan Motor Work
These are the three most common failures we see in Roswell’s summer heat, because the harder a system runs, the faster electrical components wear. A bad capacitor won’t always show itself, so we test under load rather than guessing. Fan motor replacements are quoted as a fixed price with the part specified by brand and model.
Refrigerant Recharge and Leak Repair
If your system is low on refrigerant, that fluid that moves heat out of your home has leaked somewhere. Refilling without finding the leak is throwing money away. We locate the leak, repair it, and recharge to the manufacturer’s specified charge. No shortcuts, no mystery top-offs.
Trusted Brands We Service in Roswell
We work on all major residential HVAC brands, and in Roswell that means a lot of Trane and Lennox units in the 1980s-2000s subdivisions, plus plenty of Goodman and Rheem systems in newer construction and retrofitted older homes. We stock common capacitors, contactors, fan motors, and thermostat parts locally so we’re not waiting on a warehouse in another time zone. That speeds up repair turnaround for Roswell homeowners, especially during a July heat wave when nobody wants to wait three days for a part.
Common AC Repair Problems We See in Roswell Homes
- Undersized ductwork in 1980s-era subdivisions. Homes built fast in the 80s and 90s often got duct runs smaller than the air handler wants. Static pressure spikes and blower motors fail. A repair-only approach repeats the same failure within two summers.
- Original electrical panels in older Roswell homes. Many pre-1950 houses near the historic district still carry panels sized for a window unit era. A modern condenser can trip a breaker or refuse to start, and sometimes the repair is a subpanel upgrade before the AC will even run.
- Condenser coils packed with cottonwood and pollen. Roswell’s spring pollen load is brutal on outdoor units. Cottonwood, oak pollen, and general tree debris settle into coil fins and choke airflow. Without a proper coil cleaning, a “repaired” system is back to no-cool by July.
- Hot upstairs rooms in multi-level homes. A single-zone system serving a two-story Roswell house often can’t balance temperatures. Homeowners run blowers on high to compensate, which shortens motor life. That’s a sizing and airflow problem, not something a capacitor swap will fix.

FAQs About AC Repair in Roswell
Because many homes in Roswell’s historic district have original plaster walls and pine floors that make adding traditional ductwork nearly impossible without destroying period finishes. If your system has failed and the ductwork was never designed for central air, a like-for-like repair often won’t solve the comfort problem. High-velocity mini-duct systems or ductless mini-splits let us preserve the architectural integrity of your home while delivering cold air where it’s needed. We’ll assess what you have before recommending anything. Call (478) 662-5175 for an honest evaluation.
You can’t stop Roswell’s pollen, but you can keep it from killing your AC. The single most effective thing is a full condenser coil cleaning every spring, ideally before cottonwood season peaks in May. Rinsing the outside of the unit with a hose helps, but it doesn’t clear the inner coil fins where pollen packs in. A clogged condenser causes the compressor to run hotter and fail sooner. We clean coils as part of a Roswell AC Maintenance visit, and it’s far cheaper than a compressor replacement. Call (478) 662-5175 to schedule a cleaning before the heat hits.
Not automatically. We got a call from a 1960s ranch off Old Alabama Road where the original two-ton Carrier condenser had finally quit. Our tech found a pitted contactor and a weak capacitor, but also discovered the evaporator coil was sized for a much smaller living area, and the homeowner had been running the blower on high to compensate for a hot upstairs. We replaced the capacitor and cleaned the coil, but we recommended a load calculation before any future swap. A same-tonnage replacement would have left the master bedroom still roasting at 78 degrees. Homes in Roswell subdivisions built in the 80s and 90s often have undersized ductwork, and matching old tonnage to new equipment without checking airflow repeats the failure. We run the numbers before we recommend a size.
It can. Many original electrical panels in Roswell’s older homes lack the amperage for a modern condenser, especially if the panel predates central air conditioning. If your system won’t start and the breaker trips or the panel shows signs of heat damage, a “simple” repair turns into a subpanel upgrade or a service upgrade before the condenser will even receive power safely. We’ll check the panel during diagnosis and tell you exactly what’s required, in writing. Call (478) 662-5175 and we’ll walk through what your panel can handle.
Because the motor is likely fighting undersized ductwork, and replacing the motor without fixing the airflow repeats the failure. In many 1980s-era Roswell subdivisions, duct runs were sized too small for the air handler, which spikes static pressure and overheats the blower motor. A replacement motor will work for a while, but it’s burning itself out under load. The real fix is a static pressure test, possibly duct modifications, and then the motor. That’s the difference between a repair that lasts and one that fails again in two summers. Call (478) 662-5175 for a pressure test and an honest answer.
