When your air conditioner stops cooling in a Marietta summer, the problem isn’t just discomfort. It’s a race against 90-degree heat and 80% humidity in a house that heats up fast, especially in older Cobb County homes with single-pane windows. Halden Heating & Air has done AC Repair - Marietta since 2004, and we answer the phone live, 24/7, because we know a dead AC at 9 p.m. on a Friday doesn’t wait for Monday. Most repairs run $150 to $650 depending on the part, and you’ll get that number in writing before we touch a screw. Call (229) 514-0545 and you’ll talk to a person, not a voicemail tree.
AC Maintenance
AC Maintenance is the scheduled tune-up that keeps your system from breaking down in the first place, and in Marietta’s pollen-heavy spring and muggy summer, it’s the difference between a unit that lasts 12 years and one that croaks at 8. Halden Heating & Air Marietta sends a background-checked technician to inspect, clean, and test your entire system twice a year, ideally in early spring before the cooling season kicks in. A tune-up runs $80 to $200 and includes a written report and AC Repair Maintenance Checklist for Marietta Homeowners covering what we found, what we fixed, and what might need attention later. We’re not paid on commission for what we sell, so the report is straight information, not a sales pitch.
Spring Startup Checklist
We check refrigerant pressure, capacitor health, contactor wear, and thermostat calibration. We also wash the outdoor coil and check the condensate drain line for clogs. If anything looks off, you’ll get a written price to fix it before it becomes an emergency.
Fall Shutdown Service
Before you switch to heat, we inspect the full system again. This catches issues early so you’re not surprised on the first cold evening in November. It also protects your warranty because most manufacturers require documented annual maintenance.
Styles & brands we work with
AC Service
AC Service is the umbrella term for any visit where we diagnose, repair, or tune your cooling system, and it covers everything from a quick capacitor swap to a full refrigerant recharge. Halden Heating & Air Marietta approaches every service call the same way: show up on time, track to your door, diagnose, then hand you a written price before any work starts. Most AC service visits fall between $150 and $650 depending on what we find. We service every major brand and we won’t push a replacement unless the math actually makes sense.
Diagnostic Visit
We don’t bill by the hour and make you watch the clock. Our diagnostic fee covers the time and tools it takes to find the actual problem. If you approve the repair, that fee rolls into the total.
Repair Visit
Once you approve the written price, we fix it on the spot in most cases. Our trucks carry hundreds of common parts for Trane, Lennox, Goodman, and Rheem units, so there’s no waiting on a parts run across town.
AC Unit Repair
AC Unit Repair means fixing the physical equipment in your outdoor condenser or indoor air handler, and it’s the bread and butter of what we do in Marietta from May through September. When a unit loses cooling capacity, it’s usually one of a handful of parts: a capacitor, a contactor, a fan motor, or a compressor. Halden Heating & Air Marietta carries the common OEM parts for Trane, Lennox, Goodman, and Rheem systems, so we can usually complete AC unit repair same-day. You’ll see a written price, and you’ll approve it before we start.
Condenser Repairs
The outdoor condenser unit takes the worst of Marietta’s weather. We replace fan motors, clean fouled coils, and check electrical connections for heat damage. Anything wearing out gets flagged in writing.
Air Handler Repairs
The indoor air handler houses the blower motor and evaporator coil. Noises, weak airflow, or ice on the lines point toward the air handler. We diagnose, show you what we found, and fix it with the same no-surprise pricing.
AC Capacitor Replacement
AC Capacitor Replacement is one of the most common AC repairs we perform in Marietta, and in many cases it’s the reason your outdoor unit hums but won’t start. The capacitor is the silver cylinder that gives your compressor and fan motor the electrical jolt they need to spin up. Marietta’s heat and humidity wear these down faster than the national average, usually after 5 to 10 years. A capacitor replacement typically runs between $150 and $350 including the part and labor. Halden Heating & Air Marietta stocks these on every truck, so this is almost always a same-day fix. Safe handling matters here because capacitors store voltage even after the power is off, which is why we never recommend homeowners open their outdoor unit themselves.
Signs Your Capacitor Is Failing
You might hear a clicking sound from the outdoor unit, the fan might spin slowly, or the unit might struggle to start on a hot afternoon. If you’re hearing a hum but no spin, cut power at the breaker and call us. Running the unit with a bad capacitor can overheat the compressor.
Dual vs Single Capacitors
Many newer units use a dual capacitor that serves both the compressor and fan motor. We test both sides under load, because a capacitor can look fine with a basic meter and still fail when the unit kicks on at full draw.
AC Recharge
AC Recharge, or refrigerant recharge (topping off the coolant your system needs to produce cold air), is not a routine maintenance item. If your system is low on refrigerant, it means there’s a leak somewhere, and the right fix is finding and sealing that leak, not just pumping in more coolant. In Marietta’s long cooling season, a system that’s 10-20% low can run constantly and still not hit your set temperature. A recharge typically falls in the $150 to $500 range depending on the refrigerant type and how much is needed. Halden Heating & Air Marietta handles R-22 and R-410A systems, and we’ll always tell you if the leak is worth fixing or if the math points to replacement.
R-410A vs R-22 Systems
Older R-22 systems are getting more expensive to recharge because R-22 has been phased out. If we’re topping off an R-22 system, we’ll give you a straight answer about what future recharges will cost and when replacement starts to make more sense.
Leak Detection First
We use electronic leak detectors and UV dye to find the source before adding refrigerant. A recharge without a leak fix is money that literally evaporates within a season or two.
Emergency AC Repair
Emergency AC Repair is what we do when a cooling failure hits at the worst time, and in Marietta, that’s almost always the first 95-degree week of June. Halden Heating & Air Marietta answers calls live 24/7, and we run emergency calls in Marietta, our AC Repair in Smyrna, Kennesaw, and the surrounding area with no overtime surcharge for showing up at 11 p.m. Emergency calls fall into the same $150 to $650 repair range, and you’ll get the written price before we open the unit. If your AC goes out late on a summer night, don’t leave it running in misery and don’t start flipping breakers repeatedly. Call us at (229) 514-0545 and talk to a live dispatcher who can get a technician headed your way.
What Counts as an Emergency
No cooling at all on a hot day, a burning smell from the vents, or a unit that trips its breaker repeatedly. These are calls we prioritize because they become health issues in Maria’s humidity, especially in homes with infants, elderly family members, or anyone with a respiratory condition.
After-Hours Response
Our on-call technicians carry the same parts stock as daytime crews. You won’t be told to wait until Monday for a capacitor or a run capacitor. If it’s fixable that night, we fix it that night.
AC Not Blowing Cold Air
AC not blowing cold air is the number one reason Marietta homeowners call us between May and October, and the root cause is almost always one of five things: low refrigerant, a failed capacitor, a clogged air filter, a frozen evaporator coil, or a thermostat that’s lost its calibration. Before you call, check your filter and your thermostat batteries, because those two things account for maybe 20% of the calls we run in Marietta. If those look fine, the issue is inside the system, and that’s where Halden Heating & Air Marietta comes in. A diagnostic visit is $89, and if you approve the repair, that fee is applied to the total. Most no-cold-air calls we run in Marietta end up between $150 and $650 all-in.
Frozen Coil Problems
A frozen evaporator coil often means restricted airflow, a dirty filter, or low refrigerant. If you see ice on the copper lines outside, turn the system off and let it thaw before we arrive. Running a frozen system can destroy the compressor, and that’s a $2,000 part, not a $200 one.
Airflow and Duct Issues
Sometimes the AC is fine and the problem is that air isn’t moving through the house. Collapsed ductwork, closed dampers, or a dead blower motor all show up as warm air at the vents. We check static pressure on every diagnostic call to tell the difference between an AC problem and an airflow problem.
Brands We Service
We service Trane systems extensively across Marietta, and we’re familiar with the scroll compressor and ComfortLink controls on their heat pumps and straight-cool units. Trane parts are on our trucks, and we’re comfortable with their diagnostics, not just swap-and-hope repairs.
Lennox systems show up a lot in older Marietta subdivisions like East Cobb and Sandy Plains. We know the G51 furnace lineup and the XC series condensers well enough to diagnose by sound. Goodman and Rheem are the workhorses we see in newer construction around Kennesaw and Acworth, and we stock common OEM parts for both. Two brands we carry less of but service without hesitation are Goodman and Rheem, which we see frequently in Powder Springs and Mableton. Whether you have one of these or any other make, we can help.

- Warm air blowing from the vents. If your thermostat is set to 72 and the air coming out reads 82, your system is running without producing cold air. That’s usually a refrigerant or compressor issue, and running it longer won’t help. Shut it down and call before the compressor overheats.
- Hissing or bubbling sounds from the indoor unit. That can be refrigerant leaking from the evaporator coil. You can’t fix that with a can from the auto parts store, and trying to can damage the compressor. Cut power and get a pro out.
- The outdoor unit is short-cycling. If your condenser kicks on and off every 3-5 minutes, it’s overheating, losing a capacitor, or fighting a clogged coil. Short-cycling can double your power bill during a Marietta heat wave and cut the life of the compressor roughly in half.
- Water pooling around the indoor unit. The condensate drain line can clog with algae and mold, especially in Marietta’s humidity. That backs water up into your house, and if you’ve got a drain pan here in a Cobb County home with hard water, scale buildup makes clogs more common. Left alone, it damages floors and drywall and can trip the float switch and shut the system down.
- Electrical smells or a breaker that trips repeatedly. A burning smell from the unit often means a capacitor that’s blown or a motor that’s seizing. If the breaker trips more than once, stop resetting it. Repeated resets can arc and permanently damage the electrical panel, and that’s a much bigger bill.

How Much Does AC Repair Cost in Marietta?
A typical AC repair in Marietta runs $150 to $650 depending on how much AC Repair costs based on what part failed and how accessible it is. Capacitor replacements sit at the bottom of that range, usually $150 to $350. Refrigerant recharges with leak repair tend to land in the $250 to $500 range depending on the refrigerant type and how much the system needs. Blower motors, fan motors, and contactors usually fall between $250 and $500. Compressor replacements are the big one: they can push past the $650 mark and often trigger a replacement conversation instead, and we’ll give you that math in plain language. At the high end of the range in Marietta, a hard-start kit plus a capacitor plus a contactor might hit $650 on an older R-22 system. What affects the price is part cost, refrigerant type, system age, and whether we’re working on an R-22 or R-410A unit. To avoid overpaying, get a written price before work starts and walk away from any company that won’t commit to a number upfront. Our free estimates include the diagnostic, the written price, and our 365-Day Done Right Promise on every repair.
