Why Meadowsweet Heating & Air Is Dunwoody’s Preferred Furnace Repair Company
Luis Serrano leads our team with a straightforward rule: treat every Dunwoody home like it belongs to someone who will notice how it’s left. That’s not a slogan here. It’s the Cedarwell Care Promise, and it means a written price before any work starts, shoe covers and drop cloths on every visit, and a photo of the clean-up sent before our crew pulls out of the driveway.
Dunwoody homeowners call us because we don’t do vague. We service nine equipment brands including Goodman, Rheem, and York, which covers most of what’s installed in the split-levels and ranches built across this area between the 1970s and early 1990s. Our techs know that a furnace in a Dunwoody Club Forest attic behaves differently than one in a Perimeter Center condo. That local knowledge saves you money because we’re not guessing at what’s wrong. We’re checking what actually fails here. Every job is backed by the 365-Day Done Right Promise. If it’s not done right, we make it right. No fine print, no runaround.
Boiler Repair in Dunwoody
Boiler repair in Dunwoody is a different animal than furnace work, and if your home still runs on a boiler, you’re likely in one of the older ranch houses near Dunwoody Country Club or off Chamblee Dunwoody Road where hydronic systems were more common in the early construction years. This work involves diagnosing circulation problems, bleeding radiators, addressing pressure faults, and repairing or replacing zone valves. Boiler repair in Dunwoody runs $150-$700 depending on whether we’re replacing a single component or addressing multiple issues across the loop. A boiler that won’t hold pressure or makes banging sounds in the pipes needs attention before it leaks through a finished ceiling.
Circulator and Zone Valve Work
A failed circulator pump stops hot water from moving through the baseboards or radiators, and the house goes cold even though the boiler fires. We replace worn circulators and sticking zone valves in Dunwoody homes regularly, particularly in systems that haven’t been flushed in years. Hard water mineral buildup from Dunwoody’s municipal supply shortens the life of these components.
Air-Bound Radiators and Pressure Faults
Radiators that are hot at the bottom and cold at the top usually have trapped air, not a failed boiler. We bleed the system, check the expansion tank, and confirm the pressure relief valve is doing its job. Leaving air in the loop strains the circulator and leads to a louder, less efficient system.
Gas Furnace Repair in Dunwoody
Gas furnace repair in Dunwoody is the core of what we do from November through March, and the job starts with answering one question: why did the unit stop producing heat? Most calls involve failed ignitors, dirty or cracked flame sensors, bad gas valves, or inducer motor problems. Gas furnace repair in Dunwoody runs $150-$700, and the specific price depends on the part and how many components have been affected. A furnace that lights and then shuts off after a few seconds is usually a flame sensor issue. A unit that hums but never fires often points to an ignitor or gas valve.
Short-Cycling and False Static Pressure
In Dunwoody’s volume-built 1970s and 1980s subdivisions, gas furnaces were wired into original builder-grade flex ductwork that was almost never replaced. Decades of attic humidity cycling has left ducts collapsed or disconnected at joints. So a furnace repair that only addresses the unit itself will read a false static pressure and fail again. We check the whole path, not just the box.
Propane and Heat Pump Hybrid Setups
Rural Dunwoody properties where natural gas was never run often use propane furnaces paired with heat pumps. Those hybrid systems fail differently, and a standard gas-furnace visit misses the defrost control or changeover valve failure that’s actually causing the no-heat call. Our techs ask whether you’re on propane or natural gas before we even arrive, because it changes what we bring and what we test.
Trusted Brands We Service in Dunwoody
We work on Goodman, Rheem, York, and Daikin furnaces, along with five other leading brands. Because we service such a wide range across Dunwoody, our trucks carry common replacement parts for these units, which means faster repairs for you. A Daikin in a Perimeter Center condo and a Rheem in a ranch off Womack Road both respond to our diagnostic tools the same way: honestly, when we know what to look for. We stock flame sensors, ignitors, capacitors, and gas valves for the brands most common in Dunwoody’s housing stock, so we’re not waiting on a parts shipment while your family sits in a cold house. If your brand isn’t one we stock parts for, we’ll tell you that upfront and give you a realistic timeline.
Common Furnace Repair Problems We See in Dunwoody Homes
- Delayed flame sensing in vented attics: Dunwoody’s 1970s-80s builder-grade Carrier and Goodman units sit in attics that cycle from 130-140°F summer heat to winter cold, which stresses the control board and flame sensor. That delayed sensing shuts the furnace down repeatedly, and a homeowner hears the unit try to light and fail.
- Heat exchanger cracks from short-cycling: Homes originally sized for lower insulation standards now have tighter envelopes but unchanged furnace tonnage. The heat exchanger flexes through more cycles than it was designed for, leading to cracks that put carbon monoxide risk on the table.
- Blower motor and capacitor failures: The sustained Georgia heat in Dunwoody’s vented attics degrades capacitor windings faster than national averages predict. A furnace that turns on but won’t push warm air through the house is usually a blower motor or capacitor issue.
- Collapsed or disconnected flex duct: This is the defining failure mode for Dunwoody’s housing stock. Original builder-grade flex duct, decades old, sits in unconditioned attics and breaks at the joints. The furnace fires perfectly and the house stays cold because the warm air never reaches the rooms.
Pricing for Furnace Repair in Dunwoody, GA
We give you a written price before any work starts. That’s the Cedarwell Care Promise and it applies to every visit, every time. Here’s what furnace repair in Dunwoody costs with us:
| Service | Typical Range in Dunwoody |
|---|---|
| Gas Furnace Repair | $150-$700 |
| Boiler Repair | $150-$700 |
The spread exists because a flame sensor replacement is a quick fix, while a gas valve replacement on a hybrid propane system takes longer and costs more. What drives the price up: multiple failed components, high-end brand parts, and attic access that’s tight or unusually hot. What doesn’t drive it up: the time of night you call. A live person answers at (747) 966-3037 at 3 a.m. the same way they do at 3 p.m. We don’t charge overtime for nights, weekends, or holidays. Estimates are free.

FAQs About Furnace Repair in Dunwoody
Your furnace has power and the thermostat is sending a signal, but something in the ignition sequence is failing. In Dunwoody homes with vented attic units, the most common culprits are a dirty or cracked flame sensor, a failing ignitor, or a bad control board that’s been stressed by the 130-140°F attic heat during summer. The furnace tries to light, doesn’t confirm the flame, and locks out for safety. Call (747) 966-3037 and we’ll walk you through what to check before we send someone out.
Yes, and it matters for both the diagnostic and the parts. Propane burns differently, leaves different residue on the flame sensor, and often runs through a changeover valve if the property has a hybrid heat pump setup. A standard natural gas visit that doesn’t account for propane pressure, the regulator, or the defrost control will miss the real problem. Our techs ask about fuel type before they arrive and carry propane-specific parts on the truck for Dunwoody’s rural properties.
Yes. When we come out for a no-heat call on a Dunwoody heat pump system, we test the outdoor unit, the air handler, the electric backup strips, and the defrost control. The problem is often a failed defrost board or a changeover valve, not the backup furnace itself. We don’t fix the furnace, declare victory, and leave you with a heat pump that still can’t pull heat when the temperature drops. The visit covers the whole heating system.
Furnace repair in Dunwoody runs $150-$700 with our team, and the price lands where it lands based on the part and the complexity. A flame sensor replacement sits at the low end. A gas valve replacement on a propane system with a failed defrost control sits at the high end. Attic access that’s cramped or crowded with stored items adds labor time. You’ll get the exact written price before any work starts, so there’s no guesswork. Call (747) 966-3037 for a free estimate.
Yes, and we recommend it when we’re already in the home. If your furnace in Dunwoody has failed because of a dirty flame sensor or a weak capacitor, the rest of the system probably needs attention too. We’ll inspect the duct connections, check the static pressure, clean the burners, and confirm the inducer motor is pulling correctly, all as part of the visit. We quote the repair and the tune-up separately, in writing, so you decide what gets done.
One More Thing About Dunwoody Furnaces
Our tech was called to a 1980 split-level in Dunwoody Club Forest whose 100k-BTU Carrier gas furnace was short-cycling. Testing found a bad capacitor on the inducer motor and failed flex duct connections in the 140°F attic pinching static pressure. We replaced the capacitor, re-sealed the plenum, and reset the gas valve. The homeowner reported their utility bill dropped over the next month. That’s the job: find what’s actually broken, fix it, and leave the house warmer than we found it.
If your furnace is struggling in Dunwoody, call (747) 966-3037 today. A live person answers, you’ll get a written price, and the crew that shows up will treat your floors, your kids, and your pets like they matter. Because they do.
