Marco Benitez leads our Sandy Springs team under The Garrison Standard, the same operating discipline that has defined this company since 2003.

Why Dalton Heating & Air Sandy Springs Is Sandy Springs’s Preferred Furnace Repair Company
Homeowners in Sandy Springs call us because they’re done with no-shows and prices that shift at the door.

That’s not a policy, it’s how we operate.
Our Sandy Springs dispatch is coordinated from the brand’s Atlanta office, with crews serving the city locally. That means when a furnace dies on a February night in the Riverside Drive area, we’re not pushing a callback window. You get a live person on the phone, and a tech headed your direction with a written estimate before anyone touches a screwdriver.
What really builds trust here is the 365-Day Done Right Promise. If the repair doesn’t hold, we come back at no charge. No fine print, no upgrade pitch. Just a written guarantee on every repair.

Styles & brands we work with







Boiler Repair in Sandy Springs
Boiler Repair in Sandy Springs runs $150 – $700, and it’s a different animal than furnace work. Homes in the older pockets of the city, especially along Riverside Drive and some of the 1960s ranches near the river, still run hydronic systems that depend on a boiler and radiators. When a boiler fails here, it’s usually a bad circulator pump, a failing aquastat, or air trapped in the loop. The symptoms are usually uneven heat, banging pipes, or no heat at all.
We diagnose the system as a whole, not just the part that failed. A boiler that keeps cycling on and off in a slab-heated ranch often points to a clogged heat exchanger or low water pressure, not a faulty thermostat. Our techs pin down the actual cause before quoting the fix, and the price is in writing before any work begins.
Circulator Pump Failures
A bad circulator pump is the most common boiler repair we see in Sandy Springs. The pump pushes heated water through the radiators or baseboards, and when it seizes or the bearings wear out, heat stops moving. Homeowners notice the boiler fires, but the house stays cold.
Replacing a circulator pump on a hydronic system in a Sandy Springs crawl space typically runs $300 – $550 depending on the pump size and access. We explain exactly what failed and why, then fix it so the system runs balanced.
Air-Bound Hydronic Loops
Air gets trapped in boiler loops more often in older Sandy Springs homes with original piping. The symptom is usually gurgling at night and radiators that are hot at the bottom and cold at the top. Bleeding the loop and checking the pressure-reducing valve usually resolves it.
If the loop keeps ingesting air, there’s usually a leak at a radiator valve or an undersized expansion tank. We find the source before it rots out a floor joist in a crawl space.
Gas Furnace Repair in Sandy Springs
Gas Furnace Repair in Sandy Springs runs $150 – $700, and most jobs come down to three areas: ignition, gas flow, or airflow. A furnace that won’t fire on a 28-degree Sandy Springs night is usually a dirty flame sensor or a failed hot-surface ignitor. A furnace that fires and then shuts off seconds later often points to a cracked heat exchanger, a failing limit switch, or a blocked flue.
We don’t guess. Our techs test gas pressure at the valve, check the thermocouple or flame sensor output, and inspect the heat exchanger with a camera when the symptoms indicate a crack. Gas-adjacent work is dangerous, so we never advise homeowners to open a gas valve or pull a burner assembly themselves. A bad gas valve replacement, a broken manifold connection, or an improperly seated burner can leak carbon monoxide into a house. That’s why we recommend a trained professional for any gas furnace repair, and why our techs carry combustion analyzers on every Sandy Springs call.
Ignitor and Flame Sensor Failures
Hot-surface ignitors wear out, especially in furnaces that cycle frequently during Sandy Springs’s winter cold snaps. The ignitor glows to light the gas, and when it cracks, the furnace locks out. A flame sensor that’s coated in residue fails to confirm the flame and shuts the system down as a safety measure.
Replacing a hot-surface ignitor in a Sandy Springs home usually runs $180 – $350. A flame sensor replacement is usually $150 – $250. Both are fast, predictable repairs, and we carry common ignitor and sensor part numbers for Carrier, Goodman, Rheem, and Trane furnaces in our local stock.
Limit Switch and Gas Valve Work
A furnace that short-cycles in a Sandy Springs split-level is often tripping a limit switch because of restricted airflow, not a bad switch. Replacing the switch without fixing the airflow condemns the new part to the same death. We test static pressure and inspect the filter, blower wheel, and duct restrictions before we call a limit switch bad.
A failing gas valve usually shows up as intermittent no-heat calls. The valve opens, the burners light, then the valve drops out. Replacing a gas valve in a Sandy Springs furnace typically runs $350 – $600 including the part and labor. We pressure-test every gas connection after the repair, and we’re obligated to do so by The Garrison Code.
Trusted Brands We Service in Sandy Springs
Our Sandy Springs techs are factory-trained to service all nine major residential HVAC brands, and we stock parts locally for the ones most common in this market. Carrier is everywhere here, especially in the older homes where original units are still running. We also service a lot of Bryant and American Standard furnaces in the newer subdivisions, and Daikin furnaces in the 1990s-era townhome clusters.
That brand coverage matters when a 1990s furnace needs a control board or a specific inducer motor. We keep common Carrier and Bryant parts in our local stock, and we can have rarer Daikin or American Standard components the next morning. Same-day repair is realistic when the part is on hand, which is why stocking for the brands actually installed in Sandy Springs matters more than a national parts catalog.

AfterCommon Furnace Repair Problems We See in Sandy Springs Homes
- Cold floors and uneven heat in 1960s slab-ducted ranches. The ductwork runs through uninsulated concrete, and registers lose most of their heat before it reaches the room. We often find the furnace is fine, but the duct leakage is so bad the system can’t satisfy the thermostat.
- Limit switch failures from single-zone split-levels. The upstairs is freezing while the downstairs overheats, so the furnace short-cycles all winter. The limit switch trips repeatedly, and eventually the constant heat stress kills it. Fixing the switch without addressing the airflow is a temporary patch at best.
- Pine-needle and pollen buildup on furnace intake and exhaust vents. Sandy Springs’s tree cover is beautiful until it clogs a concentric vent kit. Our techs regularly clear blocked intakes on furnaces in tree-shaded lots, especially in spring when pollen and pine needle drop peak.
- Electrical issues in 1970s and 1980s electrical panels. Many Sandy Springs homes don’t have a dedicated breaker for a modern ECM blower motor. A furnace repair that includes a motor upgrade can reveal a panel that can’t handle the load, and we flag it before we touch anything live.

FAQs About Furnace Repair in Sandy Springs
Cold spots in a Sandy Springs ranch home usually aren’t a furnace problem at all. The furnace heats the air fine, but the original slab ductwork leaks so much heat into the concrete that the air arrives lukewarm. We’ve seen this on dozens of 1960s-era ranches where homeowners replaced the furnace and the cold spots didn’t move. The fix is usually duct sealing, register balancing, or adding returns, not another furnace part. Call (478) 400-5908 and we’ll pressure-test your ductwork before selling you anything.
It’s worth repairing if the heat exchanger is intact and the repair is under $700. Our crew recently repaired a 1972 Carrier furnace in the Riverside Drive area where the homeowner had kept the original unit alive through sheer persistence. The heat exchanger was intact, but the blower motor was pulling 4.2 amps on a 2.8-amp rated winding, and the capacitor was down to 3.8 microfarads from a 5.0 spec. We replaced both, checked static pressure at 0.62 inches, and the old unit fired up. With the right parts, even a 50-year-old furnace can keep a Sandy Springs home warm. We’ll give you an honest read on whether repair or replacement makes sense, and the repair quote is always in writing before we start.
A furnace that trips the breaker in a 1980s Sandy Springs home usually has a failing blower motor or a compromised electrical panel. Many of these homes lack a dedicated circuit for a modern ECM blower motor, and the existing breaker was sized for a much smaller load. We test the blower amp draw and inspect the breaker before recommending a motor replacement or a panel upgrade. This is electrical work, and it’s not safe to keep resetting the breaker repeatedly. Call (478) 400-5908 and we’ll diagnose the electrical side properly.
A furnace repair alone rarely fixes humidity in a Sandy Springs home, but it can be part of the picture. If the blower motor is running too hot or the burners are overfiring, the system may short-cycle and never run long enough to move air through the ductwork consistently. A proper airflow setup and a correctly sized flame can help the system feel less clammy. But real humidity control in Sandy Springs usually comes from properly sealed ductwork and a system that runs long enough to actually move air. We’ll show you what’s contributing and what won’t work.
Yes and no. A furnace in a Sandy Springs crawl space is harder to access than one in a garage closet, especially when the crawl space has low clearance or the soil stays damp from the Chattahoochee’s proximity. Ground-level moisture accelerates rust on heat exchanger seams and electrical connections. Our techs go in prepared for tight access and often recommend a dehumidifier or vapor barrier if the moisture is severe. The repair cost itself usually doesn’t change much, but the diagnosis is more thorough because we can see the conditions the furnace lives in.
