Furnace repair in Roswell typically runs $150 – $700, and most calls we handle are diagnosed and fixed the same day. Whether you’re in a 1980s subdivision off Holcomb Bridge Road or a larger two-story home near the Chattahoochee, we arrive with the parts to service Carrier, Trane, Lennox, Goodman, and Rheem equipment. A live person answers when you call (478) 606-5046, any hour, any day.
Our crews know Roswell’s housing stock intimately: attic-mounted air handlers, slab foundations, crawlspaces, and the occasional boiler in older East Cobb homes. That local familiarity means we diagnose faster and quote a written price before any work begins, so you’re never guessing what the repair will cost.
Why Meadowsweet Heating and Air Alpharetta Is Roswell’s Preferred Furnace Repair Company
Roswell homeowners call us because we treat the house the way they’d treat it themselves. Every technician is background-checked, uniformed, and follows the C.A.R.E. values code on every visit: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, and Explain the price before the work. Shoe covers and drop cloths go down before tools come out, and you get a photo of the clean-up before the crew leaves. That’s the Cedarwell Care Promise, and it’s included on every job, not offered as an upsell.
Luis Serrano leads our team with a simple standard: if a job isn’t done right, it isn’t done. That’s why every repair carries the 365-Day Done Right Promise. If something fails within a year of our fix, we make it right. No runarounds, no fine print. For families in Roswell with kids, pets, and busy routines, that promise matters as much as the repair itself.
Styles & brands we work with
Boiler Repair in Roswell
Boiler repair in Roswell is less common than furnace work, but a number of older homes in the historic district and parts of East Cobb still rely on hydronic heat. When a boiler’s circulator pump fails or a zone valve sticks, the result is usually a cold room and a pressure gauge acting erratically. A typical boiler repair in Roswell runs $150 – $700, depending on whether we’re replacing a thermocouple, flushing a sediment-clogged loop, or diagnosing an air-bound radiator line.
Circulator pump and zone valve work
Boilers in Roswell’s older homes often have multiple heating zones controlled by individual valves. When one zone stops heating, the pump or valve is usually the culprit. We test voltage, check the valve actuator, and replace only what’s failed.
Boiler lockouts and pressure issues
Hard water in parts of Roswell contributes to sediment buildup inside boiler heat exchangers. That sediment causes overheating, pressure spikes, and lockouts. Flushing the system and checking the expansion tank usually restores steady operation.
Gas Furnace Repair in Roswell
Gas furnace repair in Roswell covers the bulk of our winter calls, and the most common issues are failed igniters, dirty flame sensors, gas valve failures, and cracked heat exchangers. A gas furnace repair in Roswell generally costs $150 – $700. If a furnace is blowing cold air or short-cycling, the sequence of operation tells us exactly where the failure sits.
Igniter and flame sensor replacement
Hot-surface igniters crack after years of heating cycles, and flame sensors get coated with combustion residue. Both are straightforward fixes. Igniter replacement runs $180 – $350 in Roswell, and a flame sensor cleaning or replacement sits at the lower end of that range.
Gas valve and heat exchanger diagnosis
When a gas valve fails, the furnace won’t light at all or produces weak, uneven flame. Heat exchanger inspection and replacement runs $400 – $700 and is the repair we never rush: a cracked heat exchanger can leak carbon monoxide into the home, which is why we test with a combustion analyzer before calling it safe.
Trusted Brands We Service in Roswell
Our techs are qualified on nine major equipment brands, including Trane, Lennox, Goodman, and Rheem. For Roswell customers, that means we stock common parts locally so a furnace repair doesn’t stall waiting on a distributor. Most igniters, flame sensors, capacitors, and control boards for these brands fit right on the truck, and we can have less common parts sourced within one business day. If your furnace is a Carrier from the 1980s or a newer Lennox, we’ll know its quirks before we ring the doorbell.

AfterCommon Furnace Repair Problems We See in Roswell Homes
- Overheating condensers in the historic district. Roswell’s screening rules require condensers to be hidden from street view, which traps heat around the unit. That heat drives up compressor temperatures and can shorten the system’s life, so some furnace repair calls begin with a condenser that’s actually overheating, not a furnace failure at all.
- Cracked heat exchangers in 1980s attic air handlers. Undersized ductwork from the original build starves the furnace of airflow. That causes the heat exchanger to overheat repeatedly until it cracks. We check static pressure before replacing parts, because the furnace is often not the root problem.
- Rust on control boards and igniters in slab foundation homes. Homes without crawlspace access trap moisture near the furnace cabinet. Rust forms on control boards, igniters, and gas valve connections. We seal and reposition components where possible to slow the corrosion.
- Unbalanced zones in large multi-zone houses. East Cobb and riverside homes often have two or three zones fed by a single system. Poor static pressure balance means one zone overheats while another stays cold. Variable-speed blower motors and proper damper adjustment usually correct it.

FAQs About Furnace Repair in Roswell
In Roswell’s historic district, condensers must be screened from street view, which traps heat and raises pressure inside the refrigeration circuit. That heat migrates through the refrigerant lines and can push the furnace or heat pump past its designed operating range, triggering high-limit switch trips and overheating faults even on cold days. The fix usually involves improving airflow around the screened condenser and checking the system’s charge and airflow. Call (478) 606-5046 for an assessment.
If your 1980s home off Holcomb Bridge Road still runs an original R-22 system, a planned replacement often costs less overall than an emergency repair on a system that’s already dying. R-22 refrigerant is no longer produced, so a leak repair can cost as much as a new system. We can walk you through replacement options, written pricing, and what a modern variable-speed unit will do for your utility bills. Call (478) 606-5046 for a free estimate.
Unbalanced static pressure is the usual culprit in larger East Cobb homes with multi-zone systems and attic air handlers. When one damper closes, the extra pressure pushes airflow unevenly through the remaining zones, so one floor roasts while another freezes. We measure static pressure at the air handler and recalibrate dampers or upgrade the blower motor. We regularly replace failing blower motors in attic air handlers off Holcomb Bridge Road, where homes from the 1980s still run original Carrier furnaces. After a static pressure test showed 0.9 inches, we upgraded to a variable-speed motor and recalibrated the thermostat: the homeowner immediately noticed quieter operation and more even heat. Call (478) 606-5046 and we’ll diagnose your zone balance.
Loud banging usually comes from expanding and contracting ductwork when the blower kicks on, especially in attic installations where ducts are suspended and uninsulated. In some Roswell homes it’s also the heat exchanger expanding under uneven heat from a dirty burner. We’ll isolate the source and fix it rather than asking you to live with the noise. Call (478) 606-5046 to schedule an inspection.
Short-cycling in crawlspace homes near Holcomb Bridge Road often traces to a dirty flame sensor or an overheating limit switch tripping too early. Crawlspace moisture accelerates rust on the control board and sensor connections, which produces false readings and rapid on-off cycling. We clean or replace the sensor, check the limit switch, and address the moisture where possible. Call (478) 606-5046 and we’ll stop the cycling before it damages the heat exchanger.
