We’re Halden Heating and Air Marietta, and our AC Repair team knows exactly what heat, humidity, and red clay do to air conditioning in this city. Call (229) 514-0545 any hour.

Why Halden Heating and Air Marietta Is Marietta’s Preferred AC Repair Company
Marietta homeowners call us because we put the price in writing before any work starts. That’s not a special offer. It’s how every single job works. Andre Fuller, who leads our team, set that standard because too many Marietta residents had been through the old routine: a four-hour window, a vague quote, and a number that changed at the door. We don’t do that.
Andre’s crews know these neighborhoods. They know the 1960s split-levels off Powder Springs Road run undersized returns. They know the 1990s tract homes near Kennesaw Mountain sweat through long attic duct runs every August. That local knowledge means faster diagnostics and fewer return visits. Every repair includes a written guarantee. If it fails within the coverage window, we come back free. That’s the 365-Day Done Right Promise, and it applies to every job in Marietta.
Styles & brands we work with
AC Not Blowing Cold Air in Marietta
AC Not Blowing Cold Air is the most common call we get from Marietta homeowners between May and September. The cause might be a failed capacitor, a refrigerant leak, a clogged evaporator coil, or something deeper like cracked ductwork under a slab-on-grade ranch. In Marietta’s humid subtropical climate, your system runs from April through October, and any weak point gets exposed fast. A diagnostic visit with repair typically lands between $150 and $650 depending on the part and labor involved. We hand you a written price before we touch anything. No surprises at the door.
Refrigerant Recharge Checks
A system low on refrigerant (the coolant that makes cold air) will run constantly and still leave your living room at 78°F. In Marietta, refrigerant charges run $75 to $150 per pound, and we always locate the leak instead of just topping off. A recharge without finding the leak is a band-aid.
Capacitor and Contactor Work
A weak capacitor can cause your outdoor unit to hum and fail to start, especially on the hottest afternoons when the grid is straining and your unit is under maximum load. Capacitor replacement in Marietta runs $150 to $300 parts and labor included. We keep common parts on the truck so many fixes happen same-day.
AC Maintenance in Marietta
AC Maintenance in Marietta isn’t busy work. It’s the difference between a system that survives July and one that dies on the first 100°F day. Given our clay-heavy soil and the strain of a cooling season that runs six-plus months, a tune-up every spring and fall is the smart move. A full tune-up runs $80 to $200, and we give you a written report of what we found, what we fixed, and what might fail next. Our technicians aren’t paid on what they sell, so the report is honest.
Crawlspace and Slab Checks
Homes near the Marietta Square with crawlspaces need a technician who actually looks under the house. Shifting red clay pulls duct connections loose, and a separated duct in a humid crawlspace means your AC is cooling dirt instead of your bedroom. Our maintenance visits include checking duct connections for separation and sealing gaps with mastic where needed.
Static Pressure and Airflow Testing
In east Marietta’s slab-on-grade ranches, ductboard under the concrete floor can’t be inspected visually. We measure static pressure to detect restrictions that suggest cracked or collapsed ductboard. Catching that early prevents uneven cooling and a frozen evaporator coil later. This is the kind of check you won’t get from a company just changing filters.
Trusted Brands We Service in Marietta
Our team is certified to work on Trane, Lennox, Goodman, and Rheem equipment, along with the other major manufacturers. What that means for you: we diagnose accurately the first time, because we know the quirks of each brand’s boards, motors, and charge tolerances. And because Marietta homes run all of these brands in roughly equal measure, we stock common replacement parts locally and carry many capacitors, contactors, fan motors, and thermostats on the truck. A Rheem condenser off Lower Roswell Road needs a different service approach than a Lennox split system in a Kennesaw-area split-level, and we know both. Faster parts access means shorter downtime when your casa needs relief.

AfterCommon AC Repair Problems We See in Marietta Homes
- Cracked rigid ductboard under slabs. The red clay in east Marietta expands and contracts with moisture, and over years that movement cracks the rigid ductboard under slab-on-grade ranches. The result: one bedroom at 82°F while the rest of the house holds 74°F, and a cooling bill that climbs every summer.
- Sweating attic duct runs in tract homes. Long, uninsulated flex or sheet metal ducts in 1970s-90s east Cobb attics pour condensate onto ceilings in the dog days. Fixing insulation and sealing joints stops the dripping and keeps cold air where it belongs.
- Frozen evaporator coils in split-levels. Many split-level Marietta homes were built without enough return air capacity. In July, that restriction drops airflow and ices the coil. The system shuts down or blows warm. Cleaning the coil, correcting airflow, and sometimes adding a return fixes it for good.
- Condenser failures from the clay wash. Outdoor units in Marietta sit in yards with soil that hardens like brick in August heat. Combined with grass clippings and cottonwood debris, coils clog and compressor life shortens. Our maintenance visits include a coil wash and a check of the capacitor and contactor.

FAQs About AC Repair in Marietta
The answer is usually cracked ductboard under your slab. Marietta’s red clay absorbs water in winter and shrinks in summer, slowly shifting the ground beneath slab-on-grade ranches. That movement cracks rigid ductboard, and the room farthest from the air handler loses air pressure first. We measure static pressure and seal the gap with mastic which is the exact fix that outlasts a duct tape patch. Call (229) 514-0545 and we’ll find the crack, not just recharge the system and hope.
If that 1995 Rheem is still cooling but the ductwork is original and undersized, the decision isn’t about the unit alone. A 30-year-old condenser is nearing end of life, but replacing it without fixing per-room airflow wastes the new system’s efficiency. In Marietta split-levels, we often recommend repairing the immediate failure first (a capacitor or fan motor), then doing a duct and return-air assessment before committing to replacement. Our team will walk you through what each dollar buys. Call (229) 514-0545 for an honest repair-versus-replace conversation.
Schedule it twice a year, once in spring and once in fall. Homes near the Square tend to be older construction with crawlspaces, and Marietta’s humid summers push moisture under the house. Duct connections loosen in that environment, and coils run dirty faster. A semiannual crawlspace check plus coil cleaning and static pressure testing prevents the failures we see every July. Cost runs $80 to $200 per visit. Call (229) 514-0545 and we’ll put you on a schedule that matches your house, not some national average.
Yes, and it happens all the time here. A capacitor delivers the starting jolt your compressor and fan motor need. When it weakens in the heat, the outdoor unit hums and won’t start. The system might run one day and fail the next. That failure often shows up on the first 100°F afternoon because the capacitor is degraded, not dead, until maximum load hits it. We replace capacitors for $150 to $300 and test the start winding to make sure the motor isn’t next. Call (229) 514-0545 if your unit is humming and not spinning.
Yes. That sweating means the duct’s outer jacket is either uninsulated, torn, or the joints are leaking conditioned air into a 140°F attic. The condensation then drips through the ceiling. In east Cobb’s 1970s and 1980s tract homes, we regularly replace or re-insulate those long attic runs, seal joints with mastic, and rebalance airflow so the system doesn’t work harder than it should. This is a repair, not a replacement of your whole system, and it’s one of the most underrated fixes in Marietta. Call (229) 514-0545 and we’ll inspect the full run.
