Straight answers to the questions we hear most from homeowners across Marietta and Cobb County. If your question isn't here, call us at (478) 662-5175 and we'll talk it through.
Pricing & Cost FAQs
Most HVAC repairs in Marietta run between $150 and $650 depending on the failed part and system age. A capacitor replacement is usually on the low end, while a blower motor or control board lands higher. At Brandt HVAC Co Marietta, you get a written price before any work begins, so there's no surprise when the bill comes. Devin Marlowe and our team will show you the exact number, explain what's actually wrong, and let you decide. Call (478) 662-5175 for a free estimate on your specific system.
A full system replacement in Marietta typically costs between $6,500 and $14,000 depending on home size, efficiency rating, and ductwork condition. That's a wide range because a 1,200-square-foot ranch in Fair Oaks needs far less than a two-story in Vinings. We give you a written fixed price after a load calculation, never a ballpark guess. Financing and rebate paperwork are handled by our team. Call (478) 662-5175 to schedule a free in-home estimate with a real installed price.
A seasonal AC or furnace tune-up in Marietta generally costs between $89 and $180. Our maintenance visits are flat-priced and include a written report of what we found and what we did. Our technicians are not paid on what they sell, so the only recommendations you'll hear are ones that actually matter. Spring and fall are the busiest tune-up seasons in Cobb County, so booking early gets you first choice of appointment times.
Yes. Georgia Power and Cobb EMC offer rebates on qualifying high-efficiency heat pumps and air conditioners, and federal tax credits for ENERGY STAR systems remain available through the Inflation Reduction Act. The exact rebate depends on the SEER2 rating and equipment type. When we quote a replacement in Marietta, we identify every rebate and credit your system qualifies for and include it in the written price. Call (478) 662-5175 and we'll check your address.
Equipment brand, efficiency rating, labor rates, and whether the company actually does a load calculation all move the price. A company that quotes over the phone without seeing your ductwork is guessing. We quote only after seeing the home, measuring the space, and checking airflow. You'll know exactly what you're paying for and why. Every pro working under our name is required to hold the license and insurance their state requires, which is part of what you're paying for in any legitimate quote.
Service & Process FAQs
You'll know who's coming before they arrive. We send the technician's name and photo ahead of the visit, and they show a photo ID badge at the door every time. They arrive in a clean, marked uniform, diagnose the system, and give you the repair price in writing before any work starts. If you approve, the repair usually happens right then. If you don't, you owe only the diagnostic fee. That's the Threshold Standard at every visit.
Yes, every time. Before your appointment, we send the name and photo of the technician coming to your door. When they arrive, they show a photo ID badge so you know exactly who is standing there. This matters to us because we know opening the door to a stranger is a real concern for parents home with kids, older homeowners, and anyone home alone. The Threshold Verified promise is part of every job we do in Marietta.
A typical full system replacement in Marietta takes one full day, occasionally a day and a half for larger homes or difficult attic or crawlspace access. We schedule a firm install date, arrive at the agreed time, and protect your floors and entryways while we work. Before we leave, we test the system, walk you through the new thermostat, and haul away the old equipment. You get a written price and a set date before you ever sign anything.
If the repair costs more than a third of a new system's price and the unit is past roughly 12 years old, replacement usually makes more sense. If it's a capacitor or contactor under $350, repair is almost always the right call. We'll show you the repair price, the replacement price, and what you're likely to spend on repairs over the next few years, then let you decide without pressure. Call (478) 662-5175 and we'll help you think it through for your specific unit.
We install equipment we supply. That's not because we're trying to mark up parts. It's because we can't warranty labor on a unit we can't verify, and we can't verify a unit we didn't order from our supply partners. When we supply the system, the manufacturer warranty and our workmanship coverage both apply cleanly. If budget is the concern, we have financing options and can match the right equipment to what you actually need in your Marietta home.
We run a Manual J load calculation on every system replacement. That means we measure the actual heating and cooling load of your specific home, not just the square footage. Homes in Austell and Lithia Springs often have different sun exposure, insulation, and window loads than a similar-sized home in Kennesaw. Swapping in the same size without checking the load is how you get rooms that never feel right. We measure first, then recommend equipment.
Brands & Parts FAQs
We install and service Trane, Lennox, Goodman, and Rheem systems. Your best choice depends on your budget, your home's layout, and what efficiency level you're after. A Trane or Lennox system tends to land at the higher end for build quality and quiet operation, while Goodman and Rheem deliver strong value with solid warranties. We'll match the brand to your actual needs and give you a written price for each option. Call (478) 662-5175 for a free estimate.
If your AC condenser fails and the furnace is older than 10 years, replacing both as a matched pair is usually the smartest move. A mismatched system can lose efficiency, shorten the new equipment's life, and void parts of the manufacturer warranty. It also costs more in labor to do them separately later. If the furnace is still young and in good shape, you can absolutely do the AC alone. We'll show you both paths and let you choose.
For Marietta's hot, humid summers and mild winters, we recommend a minimum SEER2 rating of 15 for a new air conditioner or heat pump. Higher SEER2 units, in the 17 to 20 range, save more on cooling bills over the long Georgia cooling season, which runs roughly from May through September. The higher the efficiency, the more rebate and tax credit help you'll typically see. We'll run the numbers on your actual home and show you the payback.
In Marietta's climate, a well-maintained air conditioner typically lasts 12 to 15 years, and a furnace can reach 18 to 20. Georgia's long cooling season and high humidity put real strain on compressors and coils. Homes in Powder Springs and Woodstock with heavy tree cover sometimes see less coil corrosion than open-lot homes in Mableton. Regular maintenance, clean filters, and prompt repairs extend the life. When a system starts needing $500-plus repairs every year, replacement usually makes sense.
Licensing & Insurance FAQs
Georgia requires HVAC contractors to hold a state-issued conditioned air license, and every pro working under the Brandt HVAC Co Marietta name is required to hold the license and insurance their state requires. On top of that, the Threshold Standard means every technician is background-checked, identity-verified, and photo-badged. You'll see the ID badge at the door before they take a step inside. No exceptions.
It's the commitment every Brandt HVAC location works to. Every technician is background-checked and identity-verified. We send the tech's name and photo before the visit. They show a photo ID badge at the door, every time. They arrive in a clean, marked uniform. And the price goes in writing before any work starts. The Threshold Group doesn't pretend to be from every town. Each location is an independent local business that agreed to work to this standard.
That visit is on us, and we make it right. The Threshold Verified promise is simple: every technician is sent to you by name and photo before the visit. If anyone arrives who you were not told to expect, you don't pay for that visit. We built this policy for the homeowner who is home alone, the parent with young kids, and anyone who wants to know exactly who is at the door. That's what the name on the truck means.
Emergency & Response FAQs
We offer same-day service for urgent AC and heating failures during our business hours, which are Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. In a Marietta summer, a failed AC in a home with young children or elderly residents is a health issue, not just an inconvenience. Call (478) 662-5175 as early as you can and a live coordinator will connect you with our local team for the fastest available appointment.
In most cases, yes. We hold same-day appointment slots for cooling failures during Marietta's hot season, and our hours run Monday through Friday 7:00 AM to 7:00 PM and Sunday 7:00 AM to 7:00 PM. The sooner you call, the more flexibility we have to get a technician to your door. Tell the coordinator what the system is doing, your address, and whether anyone in the home has health concerns, and we'll get you on the schedule as quickly as possible.
First, check your thermostat is set to cool and the filter isn't clogged. Then check the outdoor unit for a tripped breaker or a frozen coil. If the coil is iced over, turn the system to fan-only and call us. Running it while frozen can damage the compressor. Warm air in a Marietta July is something we treat as a priority. Call (478) 662-5175 during business hours and we'll get a technician to you the same day in most cases.
Warranty & Guarantees FAQs
Every repair we make is covered by our workmanship warranty, and every part we install carries its manufacturer warranty. The exact length depends on the part and brand. We put the warranty terms in writing with the price, before any work starts, so you know exactly what's covered and for how long. If something fails that we fixed, call us and we'll make it right. That's the Brandt HVAC way in Marietta.
Most manufacturers cover the compressor, coils, and heat exchanger for 10 years when the system is registered within 60 days of installation. We handle the registration for you on every system we install in Marietta. Parts are covered under the manufacturer warranty, and our installation workmanship is covered separately. We'll explain exactly what's covered, what's not, and for how long, in plain language before you sign anything.
Yes, and it has to be done within the manufacturer's deadline, usually 60 days after installation. Miss that window and a 10-year parts warranty can drop to 5 years. We register every system we install on your behalf, the same week it goes in. You'll get the confirmation paperwork from us. It's a small step that protects a big investment, and it's included with every installation we do across Marietta, Smyrna, and Acworth.
Yes. Every estimate and every second opinion is free. You'll get a written price for the work, a clear explanation of what's wrong or what's needed, and no obligation to move forward. If you're comparing quotes in Marietta, ask each company whether their number is fixed or an estimate. Ours is a written price, and it doesn't change unless the scope of work changes and you approve the change first. Call (478) 662-5175 to schedule yours.
