AfterHow Much Does AC Repair Cost in Marietta?
Most AC repairs in Marietta run between $150 and $650, with the majority of homeowners paying around $325 for a typical fix like a capacitor replacement or refrigerant leak seal. At Brandt HVAC Co Marietta, our AC Repair services come with a written price before any work starts, so you’ll know the exact number before you agree to anything. A tune-up runs $80 – $200, while a full system replacement is a different conversation entirely, starting around $3,500.
That $150 – $650 range covers the most common failures we see across Cobb County: bad capacitors, failed contactors, frozen evaporator coils, clogged condensate lines, and low refrigerant. The price depends on the part, the refrigerant type, and how long the repair takes. We’ll break down every line item below so nothing is a surprise.
If your air conditioner quit today and you’re reading this at 2 a.m., call (478) 662-5175. A live person answers. No phone tree, no voicemail. We serve all of Marietta, from East Cobb to the Historic Marietta Square to West Cobb and everywhere in between.
AC Repair Cost Breakdown (2026)
Here are the line-item prices we see across Marietta in 2026. These figures include parts and labor unless noted, and they reflect what homeowners in this market actually pay, not national averages that don’t account for Georgia humidity and our extended cooling season.
| Repair Type | Typical Cost (Parts & Labor) | What It Involves |
|---|---|---|
| Capacitor replacement | $150 – $300 | Replacing the cylinder that starts your compressor or fan motor. The single most common AC failure we see in Marietta. |
| Contactor replacement | $150 – $280 | Swapping the electrical switch that delivers power to the compressor. Often fails after years of arcing. |
| Condensate drain line clearing | $120 – $250 | Clearing a clogged PVC drain line that’s causing water to back up or a float switch to trip. Marietta’s humidity makes this a frequent call. |
| Refrigerant leak repair (minor) | $250 – $650 | Locating and sealing a small leak at a fitting or Schrader valve, then recharging the system. Cost depends on leak accessibility. |
| Refrigerant recharge (no repair) | $180 – $450 | Adding refrigerant to a system that’s low. We don’t recommend recharging without finding the leak first; it’s money that leaks out again. |
| Condensate pump replacement | $220 – $400 | Replacing the small pump that moves condensate water when the air handler sits below the drain line. |
| Blower motor replacement | $350 – $650 | Replacing the motor that pushes air through your ducts. Price varies by motor type (single-speed vs. variable-speed). |
| Thermostat replacement | $150 – $350 | Installing a new thermostat, including wiring verification. Programmable and smart models cost more. |
| Evaporator coil cleaning | $180 – $350 | Deep-cleaning the indoor coil that’s caked with dust and Georgia pollen, which chokes airflow and freezes the coil. |
| Compressor replacement | $1,200 – $2,800 | Replacing the heart of the system. At this price point, many Marietta homeowners choose to compare against a new system. |
These are the numbers we quote every week. Nothing vague, no “it depends” without a range attached to it.
What Drives the Price Up or Down
Four things move the final number on your written estimate. First, the part itself: a capacitor is cheap; a variable-speed blower motor is not. Second, refrigerant type: if your system runs R-22 (banned from new production but still present in many pre-2010 Marietta homes), refrigerant is significantly more expensive than R-410A. A pound of R-22 now costs 3 to 4 times what R-410A does, which is why a recharge on an older East Cobb system can hit the top of our range. Third, access: an attic air handler in July is a brutal place to work, and tight crawlspaces in older Smyrna-adjacent neighborhoods take longer. Labor time is money. Fourth, urgency: we don’t charge after-hours premiums, but a repair at 11 p.m. on a Sunday still costs exactly what it costs, because we staff live people around the clock. The price doesn’t change based on the clock.
What Affects AC Repair Pricing in Marietta
Marietta’s climate and housing stock shape what we charge and why. Here are the local factors at play.
- Humidity and extended cooling season: Marietta runs air conditioners from March through October, often into November. That’s 8 to 9 months of runtime per year compared to 4 to 5 months in northern markets. More runtime means more wear on capacitors, contactors, and fan motors. We replace capacitors in Marietta at roughly double the rate we’d see in a milder climate simply because the systems never rest.
- Georgia red clay dust: The soil here is dense, powdery, and gets airborne. It settles on condenser coils in West Cobb and Marietta proper, insulating them and driving up head pressure. A dirty coil makes the compressor work harder, shortens its life, and pushes repair frequency up.
- Pollen season: Marietta’s spring pollen counts rank among the highest in the country. That yellow film clogs outdoor condenser coils and gets pulled into return ducts, fouling evaporator coils. Homes near heavily wooded lots in East Cobb see more coil cleaning work than homes on cleared lots.
- Housing stock age: Large portions of Marietta’s housing stock went in between 1970 and 1995. Those systems are now 15 to 30 years older than their original equipment, and many still run R-22 refrigerant. Repairing an aging system costs more because parts are scarcer and refrigerant costs more. Homes in newer developments near Kennesaw Mountain tend to have newer, more efficient equipment with lower repair costs.
- Attic and crawlspace access: Marietta homes built before central air was standard often have air handlers shoehorned into tight attic corners or low-clearance crawlspaces. Labor time goes up when our technicians can’t stand up. We quote labor honestly, and that shows up in the written estimate.
- Seasonal demand spikes: The first 95-degree week in June always brings a flood of calls from all over Cobb County. We don’t price-gouge during heat waves; our rates stay the same year-round. What changes is scheduling availability, which is why we recommend pre-season tune-ups.

AC Repair Cost by Repair Type
Here’s how common Marietta AC problems break down in real numbers, along with what you’re actually paying for.
Capacitor Replacement: $150 – $300
The capacitor is a small cylinder inside the outdoor condenser unit that stores the electrical charge needed to start the compressor and fan motor. When it fails, the fan might spin slowly, hum without starting, or not run at all. In Marietta’s humidity, capacitors fail more often because heat and moisture accelerate internal degradation. The part itself costs $15 – $70 depending on the unit’s specs. The rest of the price is labor, diagnostic time, and the guarantee we put behind the repair. This is a same-day fix in most cases.
Contactor Replacement: $150 – $280
The contactor is the switch that closes to send high voltage to the compressor when your thermostat calls for cooling. Years of electrical arcing pock the contact points until the switch no longer closes reliably. You’ll hear a chattering sound or nothing at all. The part is inexpensive, but we test the entire starting circuit while we’re there, because a failed contactor is often the first sign of a compressor drawing too many amps.
Condensate Line Clearing: $120 – $250
Your AC pulls moisture out of Marietta’s humid air. That water drains through a PVC line, and that line grows algae and mold, especially in the warm, damp conditions of a Georgia summer. When it clogs, water backs up and either trips the safety float switch (killing the system) or soaks your ceiling if the air handler is in the attic. We clear the line with compressed air or a wet-dry vac, flush it with an antimicrobial treatment, and test the float switch. Homes with air handlers in finished attics should pay attention to this one; the repair bill for a clogged line is nothing compared to the drywall repair after a ceiling leak.
Refrigerant Leak Repair: $250 – $650
Low refrigerant almost always means a leak. The leak could be at a braze joint, a Schrader valve core, or a coil. Finding it takes an electronic leak detector or UV dye, and sealing it might be a five-minute fix or require brazing. The price range reflects how long the search takes and how accessible the leak is. After the repair, we recharge the system to the manufacturer’s specified charge. If your system is pre-2010 and runs R-22, expect the high end of this range or beyond, because that refrigerant is no longer manufactured and the remaining supply is expensive.
Blower Motor Replacement: $350 – $650
The blower motor sits inside the air handler and pushes conditioned air through your ductwork. Single-speed PSC motors cost less; variable-speed ECM motors found in high-efficiency systems cost significantly more. Marietta’s extended cooling season means blower motors here log hundreds more hours per year than in moderate climates. When one fails, you’ll often notice the outdoor unit running but no air coming from your vents, or a loud grinding from the attic.
How to Save on AC Repair
Repair bills are not inevitable. Most of the expensive failures we see in Marietta could have been caught early or avoided entirely. Here’s what actually works, based on what we see in the field every week.
- Change your air filter every 30 – 60 days, more often during pollen season. A clogged filter strangles airflow, freezes the evaporator coil, and strains the blower motor. In Marietta’s spring, yellow pollen will trash a filter in three weeks. A $15 filter beats a $350 coil cleaning.
- Schedule a tune-up before summer. A pre-season inspection runs $80 – $200 and catches weak capacitors, low refrigerant, and dirty coils before they become breakdowns. The best time in Marietta is March or April, before the first heat wave. Our home page covers what a tune-up includes.
- Keep the outdoor condenser clear. The unit needs at least 2 feet of clearance on all sides. Trim back shrubs, don’t stack firewood against it, and rinse the coil gently with a garden hose (unit off) after heavy pollen or red clay dust events.
- Don’t ignore small problems. A unit that runs constantly, makes a hum but doesn’t start, or trips the breaker is telling you something. Those are cheap fixes today and expensive ones in August.
- Ask for a written price before any work starts. At Brandt HVAC Co Marietta, that’s not a favor; it’s how we work. You’ll see the line items and the total before your technician touches a tool. If a repair doesn’t make sense, you’ll know the number and can decide.

How Our Pricing Works
We don’t bid low and stack fees on later. Every repair follows the same process, and the process is designed to give you certainty before you spend a dollar.
- Diagnosis: A background-checked, uniformed technician arrives at your door. You already know their name and have seen their photo before they arrived. They show you a photo ID badge before stepping inside.
- Written estimate: You get a written price for the repair, with parts and labor broken out. The number you see is the number you pay. No work starts until you say yes.
- Repair: The technician completes the work using your approved estimate. If they find something unexpected, they stop and talk to you first with a new written number.
- Written guarantee: Every repair includes a written guarantee, and under our 365-Day Done Right Promise, if the repair fails within the warranty period, we come back and fix it at no charge. No argument, no bill.
This is the same process whether you’re in a 1950s ranch near the Square or a new build off Whitlock Avenue.
Repair or Replace: A Honest Cost Comparison
The most common question we hear isn’t about the repair price. It’s whether the repair is worth it. Here’s the math we walk through with Marietta homeowners.
The rule we use: multiply the repair cost by the system’s age. If the repair costs $600 and the system is 12 years old, that’s $7,200. Compare that to a new system at $3,500 – $7,500 installed. The closer the “repair times age” number gets to replacement cost, the more sense replacement makes.
More specifically:
- Under 8 years old: Repair almost always makes sense. The system has life left, and the part will likely be one of a few failures, not a cascade.
- 8 – 14 years old: Repair makes sense if the failure is minor (capacitor, contactor, condensate line, small refrigerant leak). Compressor failure is the line in the sand; a $2,000+ compressor replacement on a 12-year-old system often isn’t the best use of your money.
- 15+ years old: Any major repair deserves a hard look at replacement. If your system runs R-22, that alone tilts the decision toward replacement, because refrigerant will only get more expensive and harder to source.
We repair all major residential brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, so we’ll give you an honest read on your system, whatever badge is on the cabinet.

FAQs – AC Repair Cost
How much does AC repair cost in Marietta?
Most AC repairs in Marietta run $150 – $650, with common fixes like capacitor replacement at $150 – $300 and refrigerant leak repairs at $250 – $650. You’ll get a written price from us before any work begins. Call (478) 662-5175 for a free estimate.
Is it cheaper to repair or replace my AC in Marietta?
If your system is under 8 years old, repair is almost always cheaper in the long run. If it’s 15+ years old and the repair exceeds $1,000, replacement at $3,500 – $7,500 may be the better financial choice. We’ll give you an honest comparison and a written price for either path, with no pressure either way.
Can you fix my AC the same day in Marietta?
Yes, in most cases. Capacitor replacements, contactor swaps, condensate line clearings, and many thermostat issues are same-day fixes. Complex repairs like compressor replacement or a hard-to-find refrigerant leak may require a return visit. Call (478) 662-5175 and we’ll tell you honestly what the timeline looks like for your specific problem.
How much is a home AC compressor replacement in Marietta?
A compressor replacement in Marietta runs $1,200 – $2,800 parts and labor, depending on your system’s tonnage and refrigerant type. At that price, many homeowners compare the cost against a new system at $3,500 – $7,500. We’ll walk through the numbers with you in writing before you decide.
Does HVAC repair cost more at night or on weekends in Marietta?
Not with us. Our repair rates are the same at 2 a.m. on a Sunday as they are at 10 a.m. on a Tuesday. A live person answers the phone 24 hours a day, 7 days a week, and the price you’re quoted is the price you pay, no after-hours surcharge.
Why is my AC repair in Marietta more expensive than my last one?
Marietta’s humidity, pollen, and extended cooling season wear systems harder than milder climates do. A capacitor that lasted 6 years in Michigan might last 3 years here. Additionally, if your system runs R-22 refrigerant, that refrigerant now costs several times more than R-410A, which pushes any recharge or refrigerant-related repair to the high end of the range.
