AfterCompressor Repair in Marietta, GA
Our AC repair installation services for compressor repair in Marietta typically cost between $600 and $1,800 depending on whether the failure is electrical, mechanical, or refrigerant-related, and most repairs can be diagnosed and completed within one visit. The compressor is the pump inside your outdoor AC unit that circulates refrigerant through the system, and when it fails, your air conditioner stops cooling entirely. At Brandt HVAC Co Marietta, we diagnose compressor problems with a written price in hand before any work begins, so you’ll know exactly what the repair costs and what it covers. Call us at (478) 662-5175 and we’ll walk you through what’s happening with your system.
This page covers the compressor repair work we do as part of our broader AC Repair & Installation in Marietta service. If you’re not sure whether the compressor is the problem, start with the parent page for a full overview of how we diagnose cooling failures.
When You Need Compressor Repair
Compressor failures rarely happen without warning. Here are the signs Marietta homeowners report most often before they call us:
- The outdoor unit runs but blows warm air. The fan spins, the unit hums, but the air coming from your vents is room temperature. That often means the compressor isn’t pumping refrigerant.
- A hard-starting compressor. The unit tries to kick on, makes a clicking or buzzing sound, then shuts off. This is common in older Trane and Goodman units in neighborhoods like East Cobb and Kennesaw where systems run hard through the summer.
- The breaker trips when the AC cycles on. A compressor drawing too many amps will trip the circuit. This isn’t something to reset repeatedly; each trip stresses the compressor windings further.
- Rattling or grinding from the outdoor unit. Internal compressor wear produces sounds you can hear standing next to the unit. By the time it’s audible, the damage is usually past the point of a simple fix.
- The system is blowing air, but it’s not cold enough on hot days. A compressor losing efficiency will still run, but it can’t keep up when Marietta’s July heat pushes past 90 degrees.
If any of these sound familiar, don’t wait. A failing compressor strains the rest of the system, and running it can turn a $700 repair into a $2,500 replacement.
Our Compressor Repair Process
Here’s how we handle a compressor repair call at Brandt HVAC Co Marietta, step by step:
- You call, a live person answers. No voicemail, no callback queue. We take your information, ask what you’re seeing and hearing, and schedule a visit at a time that works for you. If it’s an emergency, we’ll tell you honestly what we can do.
- You get the technician’s name and photo before we arrive. Every Brandt technician is background-checked and identity-verified through the Threshold Verified standard. Before the visit, you’ll know exactly who is coming to your door, and they’ll show a photo ID badge when they arrive. If the person at your door isn’t the person we told you to expect, that visit is free and we make it right.
- We diagnose the compressor and the system around it. A compressor doesn’t fail in a vacuum. We check refrigerant levels, the capacitor, the contactor, the condenser coil, and the wiring. Sometimes what looks like a compressor failure is actually a $40 capacitor. We’ll tell you what’s actually wrong, not what’s easiest to bill.
- You get a written price before any work starts. Every repair, every time. The price includes parts, labor, and refrigerant if needed. If the numbers don’t work for you, there’s no obligation – you’ll still have a clear diagnosis.
- We complete the repair and test the system. We don’t leave until the unit is cooling, the pressures are right, and the compressor is cycling normally.
- You get a written guarantee. Every compressor repair includes a written guarantee that states exactly what’s covered and for how long. If the repair fails within that period, we return at no charge under the 365-Day Done Right Promise.
Compressor Repair Pricing in Marietta
What you’ll pay depends on what’s actually wrong. Here are the ranges we see most often in Marietta and the surrounding Cobb County area:
| Repair Type | Typical Cost Range (Parts & Labor) |
|---|---|
| Compressor capacitor replacement | $120 – $250 |
| Hard-start kit installation | $180 – $350 |
| Compressor contactor replacement | $150 – $300 |
| Refrigerant leak repair + recharge | $400 – $900 |
| Compressor replacement (under warranty) | $600 – $1,200 (labor and refrigerant) |
| Compressor replacement (out of warranty) | $1,400 – $2,500 |
These numbers reflect what we see on Trane, Lennox, Rheem, and Goodman systems in this area. Your final price depends on the brand, the age of the system, and whether a Refrigerant Recharge is needed along with recovery and replacement. Compressors on newer units under manufacturer warranty bring the cost down significantly, since the part itself is covered and you’re paying for labor, refrigerant, and related components.
Before you decide between repairing a compressor and replacing the whole condensing unit, we’ll give you an honest comparison. On a 12-year-old Goodman system, for example, putting $1,800 into a new compressor rarely makes sense compared to replacing the unit. On a 5-year-old Trane under warranty, AC Installation or repair almost always makes sense. We lay out both options with real numbers and let you decide.
Every repair quote is free, written, and yours to keep. Call (478) 662-5175 and we’ll give you an exact number before any work begins.
FAQs – Compressor Repair
How much does compressor repair cost in Marietta?
Compressor repair in Marietta typically runs $150 to $2,500, depending on whether the problem is a small electrical component or the compressor itself. Capacitors and contactors sit at the low end; full compressor replacement at the high end. Our quotes always include parts, labor, and a written guarantee, so there are no surprises. Call (478) 662-5175 for a free estimate on your specific system.
Is it cheaper to repair or replace a compressor?
It depends on the age of your system and your warranty status. If the compressor is under manufacturer warranty, repair is almost always the cheaper option, typically $600 to $1,200 for labor and refrigerant. If the system is over 10 years old and the compressor is out of warranty, replacement often makes more sense, especially if the unit uses R-22 refrigerant, which is increasingly expensive. We’ll show you both numbers side by side and let you choose.
Can you repair a compressor the same day?
In many cases, yes. Electrical component failures like a bad capacitor or contactor are same-day fixes. A full compressor replacement is a longer job and may require a follow-up visit or a full day on site, depending on the system. We’ll give you a clear time expectation when we make the diagnosis. Call (478) 662-5175 and we’ll tell you what’s realistic for your situation.
What causes a compressor to fail in Marietta?
The most common causes we see in Cobb County are power surges during summer storms, low refrigerant from a slow leak that forces the compressor to overwork, and dirty condenser coils that trap heat and raise internal pressures. Regular maintenance catches the second and third causes early. A surge protector installed at the disconnect can help with the first. We’ll explain what happened in your specific case and what you can do to prevent a repeat.
