AC Repair in Marietta - Fixed Today, No Surprise Invoice

Trusted AC Repair for Marietta Homeowners

When your air conditioner stops cooling in a Marietta summer, you need a repair team that shows up fast and tells you the truth. Brandt HVAC Co Marietta has been fixing residential cooling systems since 2003, and we answer our phones with a live person 24 hours a day. That matters in July, when the humidity off the Chattahoochee pushes indoor temperatures past 90 degrees by mid-afternoon. Devin Marlowe leads our team with one rule: every job gets a written price before any work starts. No surprises, no add-ons at the door. If your AC is blowing warm air, short-cycling, or making a noise you’ve never heard before, call (478) 662-5175. We’ll send a background-checked, uniformed technician whose name and photo arrive on your phone before they do. That’s the standard we built our name on, and it’s how every repair in Marietta starts.

AC Service

AC Service is the catch-all term for diagnosing and correcting whatever is keeping your cooling system from doing its job, and in Marietta it typically runs $150 to $650 depending on what we find. A service call at Brandt HVAC Co Marietta means a full-system inspection, not a quick glance at the thermostat. Our technicians check airflow, refrigerant pressure, electrical connections, and condensate drainage, then hand you a written diagnosis with a fixed repair price. You decide what happens next. Nothing starts without your signature.

Full-System Diagnosis

We test every major component: compressor, fan motor, capacitors, contactors, and coils. The goal is to find the root cause, not just patch the symptom. Most Marietta service calls take 60 to 90 minutes from arrival to a written quote.

Preventive Checkups

Sometimes a service call turns up nothing broken yet, and that’s good news. For $80 to $200, we clean the condenser coils, check refrigerant levels, and tighten electrical connections. That small visit can prevent a $600 repair in August.

Home comfort starts with knowing what’s actually wrong. We’ll tell you plainly, in words you understand, before any tool comes out of the truck.

AC Unit Repair

AC Unit Repair means fixing the specific mechanical or electrical failure inside your condenser or air handler, and in Marietta it most often lands between $150 and $650. What drives that range is the part. A failed capacitor is a $150 to $300 fix. A seized compressor can push toward $650 or beyond, at which point we’ll show you replacement numbers honest enough to make a real decision. Brandt HVAC Co Marietta repairs what can be repaired and tells you when it can’t.

Common Repairs We Make

Capacitors, contactors, fan motors, and refrigerant leaks are the big four in Cobb County. We stock parts for Trane, Lennox, Goodman, and Rheem units on our trucks, which means many repairs finish in a single visit.

When Repair Beats Replacement

If your system is under 10 years old and the compressor is healthy, repair is almost always the smarter money. We’ll show you the repair cost, the expected lifespan of the fix, and what a new system would run, then let you choose without pressure.

For the widest view of what’s involved, read our guide to AC Repair in Marietta. It covers the same honest process in greater depth.

AC Capacitor Replacement

AC Capacitor Replacement is the most common repair we perform in Marietta, typically costing $150 to $300 including the part and labor. The capacitor is the small cylinder that gives your compressor and fan motor the electrical jolt they need to start. When it fails, your outside unit hums but won’t spin, or the fan runs while the compressor doesn’t. It’s a quick fix, usually under an hour, and we keep the most common capacitor ratings on the truck at all times.

Why Capacitors Fail

Heat is the enemy. Marietta’s long, hot summers cook capacitors until the dielectric inside breaks down. Storms and voltage spikes from Georgia Power lines also shorten their life. If your unit is 5 to 10 years old, a capacitor failure is ordinary wear, not a sign your system is dying.

What to Expect

We test the old capacitor with a multimeter to confirm it’s out of spec, then install a replacement rated to your unit’s exact microfarad requirements. The written price covers the part, the labor, and a 365-day guarantee on the repair. If it fails within the year, the return visit is free, no argument, under our AC Repair in Mableton-standard Done Right Promise.

AC Recharge

AC Recharge means refilling the refrigerant, the fluid that moves heat out of your house, and it typically costs $200 to $500 in Marietta depending on how much refrigerant your system has lost. Here’s the important part: refrigerant doesn’t burn up or evaporate over time the way oil does. If your system is low, it means there’s a leak somewhere. A recharge without finding and fixing the leak is like refilling a tire with a nail in it. Brandt HVAC Co Marietta doesn’t do that. We charge only after we’ve located and sealed the leak, or confirmed the low reading came from a recent repair.

R-22 vs. R-410A

Older systems built before 2010 run on R-22, which is no longer manufactured and now costs three to five times what modern R-410A runs. If you have an R-22 system with a significant leak, we’ll show you what a recharge costs versus replacing the unit. Sometimes paying for refrigerant you’ll lose again is the wrong call.

Finding the Leak

We use an electronic leak detector and, on stubborn cases, a UV dye injection to pinpoint the exact fitting or coil that’s leaking. The written repair price includes the leak fix and the recharge, so you know the total before we start.

If your outdoor unit is coated in ice or the air from your vents is barely cool, review our page on AC Repair in Acworth for the same no-nonsense approach we bring to every job in the region.

Emergency AC Repair

Emergency AC Repair is for the calls that can’t wait until morning: a dead system with a baby in the house, an elderly parent on oxygen, or a downstairs that hits 95 degrees with the windows open. In Marietta, emergency AC repair typically runs $150 to $650, with no overtime surcharge for nights, weekends, or holidays. Brandt HVAC Co Marietta staffs a live phone line 24/7, which means a person answers at 2 a.m., not a voicemail. We dispatch technicians to Marietta and the surrounding Cobb County area around the clock.

What Counts as an Emergency

If the indoor temperature is climbing and someone in the home has a health condition, that’s an emergency. If it’s 72 degrees at midnight and the AC just quit, you can wait until morning and save yourself the late-night call. We’ll tell you honestly which situation you’re in when you call.

No After-Hours Price Gouging

Our labor rate doesn’t change because the sun went down. The written price you get at 11 p.m. is the same as the one you’d get at 11 a.m. That’s part of the Threshold Verified standard we hold ourselves to on every single job.

AC Not Blowing Cold Air

AC Not Blowing Cold Air is the most common symptom we hear from Marietta homeowners, and the fix usually falls in the $150 to $650 range once we diagnose the cause. Sometimes it’s a dirty air filter choking the airflow. Sometimes it’s a frozen evaporator coil, low refrigerant, or a failed compressor. The only way to know is to measure, and that’s what we do. Brandt HVAC Co Marietta starts every “not cooling” call with a temperature differential test across the coil, a static pressure reading on the ductwork, and a visual inspection of the condenser. Most causes reveal themselves in the first 30 minutes.

Things You Can Check First

Check that the thermostat is set to COOL and the fan is on AUTO. Check the air filter; if it looks like a felt pad, replace it and give the system an hour. Check that the outside unit isn’t buried in leaves or overgrown shrubs, especially in neighborhoods with old tree cover like Whitlock Avenue or the side streets off Roswell Road.

When to Stop and Call

If the copper line at the outside unit is frozen, or the unit is short-cycling on and off every few minutes, shut it down at the thermostat and call (478) 662-5175. Running a system with low refrigerant or a bad capacitor can turn a $200 repair into a $2,000 compressor replacement. Don’t let a small problem become the reason you’re replacing the whole unit.

Brands We Service

We service Trane systems more than any other single brand in the Marietta market, and we keep their most common capacitors, contactors, and fan motors stocked on our trucks. Trane units have a distinctive spine-fin coil design that requires a gentle touch when cleaning; our technicians know how to handle it without flattening the fins and killing airflow.

Rheem and Goodman show up constantly in the 1990s and 2000s subdivisions across East Cobb and Powder Springs. Rheem’s classic round-top units are easy to diagnose by sound; a clicking compressor is almost always a bad capacitor or contactor. Goodman earned a reputation for simple, durable internals, and they respond well to straight mechanical repair rather than proprietary parts. Lennox units are less common down here but we work on them regularly, particularly the multi-speed air handlers that need careful diagnostic work to isolate electronic control board failures from mechanical ones. Whether you have a Trane, a Rheem, a Goodman, a Lennox, or any other make, we can help.

Signs You Need a Pro Right Now

• Warm air from every vent. When the thermostat says 72 but the air coming out of your registers is 78 or warmer, your compressor or refrigerant system has a problem. The longer a low-refrigerant system runs, the more damage the compressor takes.
• A frozen evaporator coil. Ice on the indoor coil or on the copper line into the house means restricted airflow or a refrigerant leak. Letting it thaw on its own just postpones the diagnosis; the underlying cause doesn’t fix itself.
• Burning smell from the vents. This can be a failing blower motor or electrical component overheating inside the air handler. Shut the system off at the breaker and call us. Electrical overheating inside an HVAC cabinet is a fire risk you shouldn’t ignore.
• Constant short-cycling. If the system kicks on and off every five or ten minutes without reaching temperature, you’re overworking the compressor and burning electricity for nothing. It’s commonly a capacitor, thermostat, or airflow issue, all inexpensive fixes if caught early.
• Rattling, grinding, or squealing. New mechanical sounds mean something is loose, worn, or failing inside the fan assembly or compressor. Early intervention keeps a $250 fan motor repair from becoming a $650 compressor job.
