Furnace repair in Lithia Springs typically runs $150 – $700, and most jobs are finished in a single visit. If your heat is out on a cold December night near Sweetwater Creek or off Skyview Drive, you need a technician who knows this area’s older homes and can get there fast. Brandt HVAC Co Marietta answers the phone 24/7 at (478) 662-5175, and we send a background-checked, uniformed tech to your door with a written price before any work starts. No voicemail, no callbacks.
Lithia Springs isn’t just another stop on a route for us. The houses here are different from what you find ten miles east. We’re talking about 1960s and 1970s ranch and split-level homes with original galvanized ductwork and single-zone systems that were never designed for how families live in them today. A furnace that keeps tripping its limit switch or a blower that runs constantly without warming the back bedrooms is almost always a duct or airflow problem hiding behind what looks like a parts failure. That’s what we fix.
Why Brandt HVAC Co Marietta Is Lithia Springs’s Preferred Furnace Repair Company
Most furnace repair companies will swap the part and leave. We don’t work that way in Lithia Springs. The houses here demand more. A 1974 ranch with original ductwork won’t behave the same as a newer build off Thornton Road. Our Furnace Repair team checks the whole system: the duct static pressure, the return-air path, the electrical feed, the way the home actually breathes. That’s why we’re the call homeowners make after another company already “fixed” it once.
Every technician who comes to your home in Lithia Springs is background-checked, identity-verified, and introduced to you by name and photo before arrival. When they knock, they show a photo ID badge at the door under our Threshold Verified standard. If someone shows up who you weren’t told to expect, that visit is on us. Devin Marlowe built this company on that promise, and it holds for every call we run in Douglas County.
Our written guarantee covers every furnace repair for a full 365 days. If the repair fails, we come back free. That’s not a prorated warranty or a “parts covered, labor extra” arrangement. It’s the 365-Day Done Right Promise, in writing, on every job. For homeowners in Lithia Springs who’ve been burned by vague verbal assurances, this matters.
Scheduling and dispatch for Lithia Springs are coordinated from our Atlanta office, and crews are stationed locally to reach you quickly. Call (478) 662-5175 and a live person answers, day or night.
Styles & brands we work with







Furnace Tune Up in Lithia Springs
A Furnace Tune Up in Lithia Springs costs $80 – $200, and for homes here it’s the most protective service we offer. The humid air rising from the Chattahoochee River valley means rust on gas lines, corroded ignitors, and capacitors that fail quietly. We inspect the heat exchanger for cracks, test the ignitor or pilot, check gas pressure, verify the limit switch, and measure the blower motor’s capacitor under load. You get a written report of what we found, and a written price for anything you want fixed. No pressure.
Heat Exchanger and Safety Inspection
A cracked heat exchanger can push carbon monoxide into your living space. In older Lithia Springs furnaces, the corrosion risk is higher because of the persistent dampness along the river valley. We check visually and with a combustion analyzer, and if there’s a crack, we show you. We don’t just tell you it’s bad. We show you the photo.
Airflow and Duct Pressure Check
Most tune-ups skip this. We don’t, because in Lithia Springs it’s the thing that keeps your furnace from failing. Rusted duct joints and collapsed returns are common in these older homes. We measure static pressure and check for obvious duct leakage while we’re there. It’s a five-minute check that tells us whether a new part will actually solve your problem or just mask it.
Emergency Furnace Repair in Lithia Springs
Emergency Furnace Repair in Lithia Springs is available 24/7, with no overtime surcharge, and most emergency calls cost the same $150 – $700 range as a standard repair. When a furnace dies during a January cold snap and the temperature inside drops below 55°F, that’s a health risk, especially for older adults and young children. We treat these calls accordingly. A live person answers the phone at (478) 662-5175, every hour of every day. You’ll speak with a person, not a menu.
Same-Day Response Across Douglas County
For emergency calls in Lithia Springs, we aim to have a technician at your door within hours, not days. Our crews are stationed locally and know the roads: Skyview Drive, Veterans Memorial Highway, Thornton Road, the neighborhoods around Sweetwater Creek. When you call, we tell you who’s coming, when they’ll arrive, and what to expect.
Written Price Before We Touch Anything
On an emergency call, the process is the same as any other call. The technician walks through the problem with you, shows you what’s wrong, and gives you a written price for the repair. You approve it first. No surprises on the invoice. If the repair is covered under an existing Brandt warranty, you pay nothing for the second visit.
Trusted Brands We Service in Lithia Springs
We service all major residential furnace brands, including Trane, Lennox, Goodman, and Rheem. What matters more than the brand is the installation and the system around it. A Goodman 80% furnace in a 1972 split-level can run beautifully for years if the ductwork and return air are right. We stock common parts locally for Lithia Springs customers, so most repairs don’t wait on shipping. Whether you have a Trane in a newer subdivision off Thornton Road or a Lennox that’s been in a Powder Springs-adjacent ranch since the Carter administration, our techs have worked on it.

AfterCommon Furnace Repair Problems We See in Lithia Springs Homes
- High-limit switch trips from duct leakage. Rusted return duct joints pull attic air into the system, dropping static pressure and making the furnace overheat. The blower motor gets blamed, but the duct is the actual failure.
- Capacitor failure in humid conditions. The river valley’s dampness ages capacitors faster than dry climates. A weak capacitor makes the blower motor work harder, draw more current, and eventually fail.
- Ignitor and gas valve corrosion. Furnaces near Sweetwater Creek and along the Sweetwater and Chattahoochee corridors see more corrosion on gas valves and hot-surface ignitors, even in homes only 15 years old. The moisture intrusion is real.
- Undersized electrical panels causing voltage drop. Many original panels in Lithia Springs homes were sized for a different era. A blower motor control board that keeps burning out is often a voltage problem at the panel, not a furnace defect.
Pricing for Furnace Repair in Lithia Springs, GA
Furnace repair in Lithia Springs runs $150 – $700, parts and labor included. A hot-surface ignitor replacement is on the lower end, typically $150 – $300.

FAQs About Furnace Repair in Lithia Springs
Your ductwork is the culprit, not the furnace. Split-levels in Lithia Springs were built with single-zone systems and original galvanized ductwork that has spent 50 years rusting in Chattahoochee Valley humidity. Leaky return ducts pull attic air, airflow to the upper level drops, and the furnace runs constantly trying to satisfy a thermostat that never gets there. Sealing the returns and adding balancing dampers often fixes the comfort problem without replacing the furnace at all. Call (478) 662-5175 and we’ll measure your static pressure and show you where the air is going.
Often it’s the panel. Many homes off Thornton Road and throughout Lithia Springs still have the original electrical service sized for a 1960s or 1970s house. A modern blower motor draws more current on startup, and an aging breaker or undersized conductors cause voltage drop that trips the breaker or fries the control board. A good technician checks the electrical feed before replacing the blower. Ours do, every time. Call (478) 662-5175 and we’ll diagnose the actual failure, not just swap parts until something sticks.
Yes. Homes near Sweetwater Creek, the Chattahoochee River, and the surrounding low-lying areas sit in persistently damp air, especially in spring and fall. Furnace cabinets, heat exchangers, gas valves, and even electrical connections corrode faster in this microclimate. We see evaporator coil corrosion and rusted duct joints in homes near the river valley that we rarely see on ridge tops just a few miles west. It’s a real condition, and it changes how we inspect and repair furnaces in those neighborhoods. Call (478) 662-5175 for a repair that accounts for where your house actually sits.
Not in most Lithia Springs homes. A new 60,000 BTU furnace in an older ranch or split-level will often perform worse than the old one if the ductwork is leaky, the returns are undersized, and the home has no zoning or balancing. The new furnace’s safety controls are more sensitive, so it trips the high-limit switch on weak airflow and shuts down. The furnace isn’t defective. The system around it is. We size and check the entire system before recommending a replacement, and if a repair keeps your current furnace running safely, we’ll tell you that first. Call (478) 662-5175 for a straight answer, not a sales pitch.
The smell is mold and mildew growth inside the furnace cabinet or ductwork, caused by the river valley’s persistent humidity during the summer and fall months. When the furnace sits idle through Georgia’s humid season, condensation forms inside the unit and in the return duct runs. When you first fire it up for the season, the blower picks up those spores and pushes the musty smell through the vents. A tune-up that includes cleaning the blower wheel, checking the condensate drains, and inspecting for duct moisture will resolve it. Call (478) 662-5175 to schedule a fall tune-up in Lithia Springs before the smell gets baked into your filter and your lungs.
Last January we tuned a 1972 split-level off Veterans Memorial Highway where the Goodman 80% furnace kept short-cycling. Our tech found a rusted return duct joint pulling attic air and a 35-year-old capacitor reading 3.2 microfarads under spec. After sealing the return and replacing the capacitor, the blower motor stopped overheating and the home held 70°F without the burner cycling every four minutes.
