Luis Serrano leads our Marietta furnace repair work, and he’s built the team around one habit: name the exact problem, price it in writing before any work starts, and leave the house cleaner than we found it. That last part matters in Marietta, where crawlspace work on 1960s ranches can track dust through a hallway if the crew isn’t careful. We are, every time.
Why Meadowsweet Heating & Air Is Marietta’s Preferred Furnace Repair Company
We’re part of the Cedarwell family of HVAC companies, founded in 2004, and every job here runs on the Cedarwell Care Promise. That means three things on every Marietta call: a written price before any work starts, shoe covers and drop cloths inside the home, and a photo of the clean-up sent before the crew leaves. Those aren’t add-ons. They’re the job.
Our techs are background-checked and uniformed, and they follow the C.A.R.E. values code: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, Explain the price before the work. If you’ve got a sleeping toddler and a nervous dog when we arrive, the dog stays calm because the crew moves slowly and speaks plainly. The toddler never hears us.
Every repair is backed by the 365-Day Done Right Promise. If it’s not done right, we make it right. No runarounds, no fine print. That’s the promise Luis stands behind on every furnace we touch in Marietta.
Heating Repair in Marietta
Heating Repair in Marietta means diagnosing failures across three very different housing eras, often in the same week. A 1962 ranch off Austell Road with galvanized trunk duct in the crawlspace needs a different kind of attention than a 1997 East Cobb two-zone system with flex duct in an un-vented attic. We carry parts for both on the truck, which saves Marietta homeowners a second trip and a second labor charge.
Most heating repairs in Marietta fall between $150 and $700. A failed ignitor on a Goodman 80% furnace might sit near the low end. A heat exchanger replacement on a Rheem unit pushing 20 years old lands toward the top. We give you the exact number after diagnosis, in writing, before we touch a tool.
Short-Cycling and No-Heat Calls
When a furnace fires and shuts down repeatedly through the night, the culprit in west Marietta ranchers is often a failed capacitor or a dirty flame sensor. We test, confirm, and replace only what’s failed. No system-selling from our techs, because our techs aren’t paid on what they sell.
If the heat won’t start at all, we check the ignitor, gas valve, and control board in sequence. Most no-heat calls around Marietta Square neighborhoods are fixed in under two hours on site.
Heat Exchanger and Carbon Monoxide Concerns
A cracked heat exchanger is the repair we take most seriously, because it isn’t a comfort issue. It’s a safety issue. In older Marietta homes with shifted 1960s ductwork, static pressure changes can strain a heat exchanger for years before it fails. We scope it with a camera and show you the image. If it’s cracked, we’ll give you a written repair-versus-replace comparison and respect whichever direction you choose.
Boiler Repair in Marietta
Boiler Repair in Marietta is less common than furnace work, but it shows up in pre-war homes near Marietta Square and in rural Cobb County properties that never got natural gas service. Those systems run on propane or fuel oil, and the failures are different: fouled nozzles, weak spark on the ignitor, draft problems from undersized flues, and sediment building in the heat exchanger.
Boiler repairs in Marietta follow the same $150-$700 pricing range as furnace work. A nozzle and electrode tune-up sits low. A circulator pump or gas valve replacement runs higher. We write the price before any work begins, same as every job.
Propane Boiler Ignition and Burner Faults
Rural Marietta properties without natural gas often run propane boilers that sit idle through the shoulder seasons. The first cold snap brings ignition faults: dirty pilots, weak spark, or a burner that lights and drops out. We clean, adjust, and replace the tiny parts first before recommending anything bigger.
Outbuilding and Workshop Boiler Service
Detached garages and workshops around Marietta sometimes have their own small boiler or hydronic loop. Undersized flues and improvised venting are common out there, and draft problems look like ignition problems. We inspect the vent path and the heat exchanger together, because fixing one without checking the other just burns the next cold evening.
Trusted Brands We Service in Marietta
Our techs service equipment from nine leading manufacturers, and for Marietta homes the names we see most are Trane, Lennox, and Goodman. Many west Marietta ranchers still run Rheem units installed in the 1990s, and we keep common Rheem ignitors, flame sensors, and control boards stocked locally so turnaround stays fast. If your brand is on the truck, the repair happens today. If it isn’t, we get the part from our Marietta supply house and return at the first open slot.
Common Furnace Repair Problems We See in Marietta Homes
- Heat pump capacity collapse during Blue Ridge foothill cold snaps. When temps drop below 20°F, heat pumps lose capacity fast and auxiliary strip heat carries the load. That sustained draw burns through blower motors and strains heat exchangers on dual-fuel setups.
- Propane furnace ignition faults on rural properties. Where natural gas never reached, propane burners foul nozzles and weaken spark. Long service drives mean these failures often wait until the family is already cold.
- Static pressure problems in 1960s crawlspaces. Galvanized trunk duct in west Marietta ranches has leaked and shifted for decades. Bad airflow causes short-cycling, temperature swings between rooms, and eventually cracked heat exchangers.
- End-of-life multi-zone systems in East Cobb. Homes along East Piedmont Road and Murdock Road built in the 1990s are hitting 25-30 years on original equipment. Dual-zone dampers fail, control boards go dark, and full duct replacement triggers Cobb County permits and inspections.

FAQs About Furnace Repair in Marietta
Yes. Many rural parcels around Marietta never received natural gas service and run propane furnaces or boilers. We handle propane ignition faults, burner cleanings, gas valve replacements, and venting corrections on those systems, including units in detached workshops and outbuildings. Call (747) 966-3037 and tell us it’s a propane system when you call, so the tech brings the right test equipment.
Marietta’s position near the Blue Ridge foothills brings periodic ice storms and sub-20°F temperatures that overwhelm heat pump capacity. When that happens, auxiliary strip heat carries the load, and sustained strip-heat operation strains blower motors, heat exchangers, and electrical connections. If your furnace fails during a cold snap, it’s usually been wearing down quietly for months. Call (747) 966-3037 for same-day diagnosis.
That depends on heat exchanger condition, airflow measurements, and duct leakage. In west Marietta ranches with 1960s galvanized trunks, we commonly find static pressure problems that shorten the life of any new furnace you install. We’ll give you a written comparison showing repair cost, replacement cost, and what the ductwork means for both. No pressure, just numbers. Call (747) 966-3037 for the full picture.
Most Marietta furnace repairs finish in under two hours on site, same as they would in Cherokee or Fulton County. The difference is permitting: Cobb County requires a permit and scheduled inspection for full duct replacements, which adds lead time on bigger jobs in east Marietta. For standard furnace repairs, there’s no delay. We’ll tell you upfront if your job triggers a permit.
Yes. We service HVAC equipment in detached garages, workshops, and outbuildings throughout the Marietta area. These units often run propane and have undersized flues, so we inspect venting and heat exchanger condition together. If you heat a workspace through the winter, a tune-up at $80-$200 is cheaper than a cold shutdown in February. Call (747) 966-3037 to schedule.
