AfterFurnace Replacement in Alpharetta, GA
Furnace replacement in Alpharetta typically costs between $4,200 and $8,900 depending on furnace size, efficiency rating, and the condition of your existing ductwork and venting. Most single-family homes in Alpharetta neighborhoods like Windward, Crabapple, and Milton’s Crabapple Crossroads fall into the $5,500 to $7,400 range for a complete swap, and the job is usually finished in one day. At Meadowsweet Heating and Air Alpharetta, every replacement starts with a written price before any work begins, so you’ll know the exact dollar figure before our crew touches a single tool.
We’re part of the Cedarwell family of HVAC companies, and furnace replacement is one of the core services within our Heating & Furnace work in Alpharetta. Luis Serrano leads our Alpharetta location with one rule: a new furnace should leave your home cleaner than it found it, running quietly, and backed by a promise we actually keep. That’s exactly what the 365-Day Done Right Promise is for.
When You Need Furnace Replacement
Not every furnace problem means replacement. A repair often makes more sense, especially on units under 12 years old. But Alpharetta’s humid summers and cold snaps put real strain on heating equipment, and there are clear signs that a replacement is the smarter financial choice. Here’s what we look for:
- Furnace age of 15 years or more. A furnace installed in 2009 or earlier is running on borrowed time. Even well-maintained units lose efficiency after 15 Georgia winters, and repair costs climb fast once major components age out of warranty.
- Heat exchanger cracks or rust. This is the one that matters most for your family’s safety. A cracked heat exchanger can release carbon monoxide into your home. We always check this first when a furnace is over 10 years old.
- Repair costs piling up. If you’ve spent $600 or more on repairs in the last two winters, or a single repair quote exceeds $1,200, replacement usually wins on math. The $1,200 repair buys you maybe one more season. The $5,800 replacement buys you 15 to 20 years.
- Uneven heating between rooms. Homes in older Alpharetta neighborhoods like Saddle Creek and Huntington Ridge often have undersized furnaces from years of additions and remodels. If your upstairs stays cold while the living room roasts, the furnace may simply be the wrong size for your home now.
- Gas bills climbing without explanation. A furnace rated at 80% AFUE was standard 15 years ago. Today’s units hit 96% AFUE or better. On a 2,800-square-foot Alpharetta home, that efficiency gap can mean $25 to $40 more per month during winter.
- Strange sounds that keep coming back. Repeated banging, rumbling, or screeching after repairs signals internal wear that patchwork fixes won’t solve. The noise is the furnace telling you something is failing mechanically.
Our Furnace Replacement Process
We built our process around one idea: you should never have to wonder what’s happening in your own home, or what it will cost. Here’s how a replacement with Meadowsweet Heating and Air Alpharetta goes, step by step:
- Call and talk to a real person. A live person answers our phones 24 hours a day, 7 days a week. No voicemail queue, no automated menu. You’ll tell us about your home, your furnace, and what you’ve noticed, and we’ll schedule a visit around your family’s routine.
- In-home load calculation and equipment review. We don’t guess at furnace size. Luis Serrano or one of our background-checked technicians measures your home, checks insulation levels, counts windows, and reviews your existing ductwork. Alpharetta homes built in different decades have very different heating needs, and the right size matters more than the right brand.
- Written price, explained line by line. Before any work starts, you’ll see an itemized written price. We walk through every line with you: equipment cost, labor, any ductwork modifications, disposal of the old unit, and the final dollar figure. You approve it, or you don’t. There’s no pressure either way.
- Replacement day, done carefully. Our crew arrives in uniform, with shoe covers on before they step inside, and drop cloths laid down in every walkway and work area. We work around your family’s schedule. Quiet tools during naptime? Just tell us. Pets that need a gate kept closed? We’ll ask before moving anything.
- System testing and walkthrough. We run the new furnace through a full startup sequence, check the thermostat, test airflow at every vent, and verify the gas connections. Then we walk you through the new system: thermostat settings, filter location, and what normal operation sounds like.
- Clean-up photo before we leave. Before the crew pulls out of your driveway, we send you a photo of the clean-up area. We clean up like it’s our own house, which is one of our C.A.R.E. values, and we prove it with a photo. Shoe covers, drop cloths, and the clean-up photo are included on every job. No upsell needed because they’re never optional.
Furnace Replacement Pricing in Alpharetta
Here’s what furnace replacement costs look like in Alpharetta right now, based on the jobs we see across Windward, Crabapple, Milton, and the surrounding communities. These are honest ranges, not bait pricing:
| Furnace Type | Typical Installed Cost Range | Who It’s Right For |
|---|---|---|
| Single-stage, 80% AFUE | $4,200 – $5,400 | Budget-conscious homes where the furnace is in an unconditioned space |
| Single-stage, 92-96% AFUE | $5,200 – $6,800 | Most Alpharetta homes built in the 1980s-2000s |
| Two-stage, 96% AFUE | $6,200 – $7,800 | Homes with cold spots or noise concerns; gentler heating cycles |
| Modulating, 96-98% AFUE | $7,400 – $8,900 | Larger homes or families sensitive to temperature swings |
Three things move the price on an Alpharetta furnace replacement. First, the size of your home. A furnace for a 1,400-square-foot ranch in Alpharetta’s older neighborhoods costs less than one sized for a 4,000-square-foot home in Windward. Second, efficiency. A 96% AFUE two-stage unit costs more upfront but lowers gas bills every winter. Third, the condition of your venting and gas line. If your existing flue or gas line needs modification to meet current code, that adds to the job.
We service equipment from Lennox, Goodman, Rheem, and York, among the nine major brands we’re qualified to install. Brand matters less than correct sizing and a careful installation, and we’ll help you choose based on your budget and your home, not on a sales quota. Call (478) 606-5046 for a free replacement estimate, and we’ll give you a written number you can plan around.
What the Cedarwell Care Promise Means for Your Furnace Replacement
The furnace itself is only half the job. The other half is how your home is treated while the work happens. That’s where most HVAC companies lose families, and it’s where Meadowsweet Heating and Air Alpharetta holds a different standard.
Every job includes shoe covers and drop cloths inside the house, which protects your floors, entryway, and the play area your kids use every afternoon. Every job includes a photo of the clean-up before our crew leaves, so you can see for yourself that your home was left the way it should be. And every job is backed by the 365-Day Done Right Promise: if something isn’t done right within the first year, we make it right. No runaround, no fine print, no arguing about whose fault it is.
Our technicians follow the C.A.R.E. values code on every visit: Clean up like it’s our own home, Ask before moving anything, Respect your family’s time and quiet hours, and Explain the price before the work. These aren’t suggestions. They’re the system. If your toddler is napping at 2:00, we’ll plan the noisy work around it. If your dog gets anxious around strangers, we’ll ask where to avoid. Your house keeps feeling like your house, even mid-replacement.
Safety During Furnace Replacement
Furnace replacement involves gas lines, combustion venting, and electrical connections. These are not DIY projects. A mistake with a gas connection or venting can put carbon monoxide into your living space, and that’s a risk no one should take. Our technicians handle gas line connections, flue venting, and all startup testing with the serious caution this work demands. If you ever smell gas in your home, leave immediately and call 911 first, then your gas utility.
