Furnace repair in Sandy Springs typically runs $150 – $700 depending on the failed part, and most calls are diagnosed same day. When your furnace quits during a January cold snap, you need a crew that shows up inside the window, puts the price in writing before touching a screw, and stands behind the work. That’s how Dalton Heating & Air Sandy Springs operates, and has since 2003 under The Garrison Standard. Marco Benitez leads our Sandy Springs team. Call (478) 400-5908 and a live person answers, 24/7. No voicemail queue, no callback window.
Furnace Maintenance
Furnace Maintenance is the scheduled service that keeps your heating system from failing mid-winter, and in Sandy Springs it runs $80 – $200 per visit. Think of it as the furnace equivalent of an oil change: a technician inspects, cleans, and measures components so small problems get caught before they become $700 repairs. Our Sandy Springs crew pulls the burner assembly, checks the heat exchanger for cracks, tests the flame sensor, and measures gas pressure against the manufacturer’s spec. Every visit ends with a written report of what we found and what it means in plain English. No technician at Dalton Heating & Air is paid on what they sell, so the report is just the truth about your equipment.
Seasonal Inspection Details
We recommend one maintenance visit in early fall, before the first real cold snap. Sandy Springs sees freezing nights from late October onward, and a furnace that sat dormant for six months collects dust on the blower and debris in the flue that hurts efficiency and, in some cases, creates a carbon monoxide risk. Our visit includes a full safety check on the gas line, the burner ignition, and the venting path.
Cleaning and Calibration
The main work in a tune-up is cleaning: flame sensor, burners, blower wheel, and the condensate line if your furnace is a high-efficiency model. We also calibrate the thermostat against the actual output temperature and adjust the gas valve for proper burn. A system that burns clean runs quieter and costs less to operate, which is the whole point of maintenance.
Styles & brands we work with
Heat Pump Repair
Heat Pump Repair in Sandy Springs covers any failure in a system that both heats and cools by moving refrigerant, and most repairs land between $150 and $650 depending on the component. Heat pumps are common here because winter temperatures rarely dip below the point where they lose efficiency. When yours stops heating, it is often a defrost control, a reversing valve, or a refrigerant charge that has drifted low. Dalton Heating & Air Sandy Springs works on heat pump brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard, and every repair starts with a written price before work begins.
Defrost and Reversing Issues
The reversing valve is the part that switches a heat pump between heating and cooling mode, and when it sticks, you get cold air when you want warm air. Defrost problems tend to appear on cold, humid mornings when frost builds on the outdoor coil and the unit cannot clear it. Both are common failures we diagnose with a multimeter and pressure readings rather than guesswork.
Refrigerant and Compressor Repairs
A low refrigerant charge, which means the cooling fluid your system needs to move heat is leaking, is the most common cause of weak or no heat output from a heat pump. We find the leak with an electronic leak detector, repair the leak, and weigh in refrigerant to the manufacturer’s exact spec, not a ballpark guess. If your compressor has failed, our written estimate explains whether repair or replacement makes sense for a Sandy Springs climate like ours.
Heating Repair
Heating Repair in Sandy Springs is the broad term for any fix on a furnace, heat pump, or hydronic system, and most jobs run from $150 to $700 depending on the part that failed. Homeowners usually call us when the system runs constantly without reaching set temperature, short cycles, or simply will not start. Our technicians diagnose the exact failure with a multimeter, a manometer for gas pressure, and a combustion analyzer, so you are paying to fix the actual problem, not a guess. We arrive in uniform, background-checked, and the price is on paper before we turn a single wrench.
Common Heating System Failures
The parts that fail most often in Sandy Springs homes are igniters, flame sensors, thermocouples, blower motors, and limit switches. A cracked heat exchanger is the serious one, because it can leak carbon monoxide into the living space. Our safety check covers that on every heating call, not as an add-on.
Heating System Diagnostics
Diagnostics start at the thermostat and move through the sequence of operation: call for heat, draft inducer, igniter, gas valve, blower. When a step fails, the meter tells us, and that isolates the problem to a specific component. Most diagnostics take 45 to 90 minutes, and you get the written price for the actual repair before any work starts.
Boiler Repair
Boiler Repair in Sandy Springs covers hydronic heating systems that circulate hot water through radiators or baseboards, and most repairs fall between $150 and $700 depending on the failed part. Boilers are less common here than forced-air furnaces, but plenty of older Sandy Springs homes, especially in Dunwoody and Kennesaw, still run on them. Common failures include circulation pumps, expansion tanks, pressure relief valves, and zone valves. Dalton Heating & Air Sandy Springs diagnoses hydronic systems with the same written-price discipline we bring to every forced-air job.
Circulation Pump and Zone Valve Repairs
When one part of the house stays cold while the rest heats, the problem is usually a zone valve that won’t open or a circulation pump that has seized. The circulation pump moves hot water through the loop, and when it fails, the boiler fires but the heat never reaches the rooms. Zone valves are simpler and cheaper to replace than pumps, which is why we diagnose with a voltage meter before pricing any part.
Expansion Tank and Pressure Issues
Boiler systems need an air cushion to absorb the expansion of heated water. When the expansion tank fails, pressure climbs until the relief valve pops, which is a messy and avoidable failure. We check pressure on every boiler visit and test the expansion tank by tapping it and checking the pressure gauge, because a waterlogged tank is a $150 part that, ignored, causes a $700 repair.
Gas Furnace Repair
Gas Furnace Repair in Sandy Springs addresses failures in natural gas-fired forced-air systems, and most repairs run $150 – $700 depending on the component that failed. Gas furnaces are the most common heating system in this part of Georgia, and they have a specific sequence of operation that makes diagnosis straightforward for a trained technician. We work on gas furnaces from Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Every repair begins with a written price and every repair carries a full-year written guarantee under The Garrison Code.
Igniter and Flame Sensor Failures
The hot surface igniter is the glow plug that lights the gas, and it is the most common gas furnace failure we see in Sandy Springs. Most igniters last five to seven years, and when one cracks, the furnace tries to start, fails, and goes into lockout. The flame sensor is the safety device that confirms the burners lit, and when it gets coated with buildup, it shuts the gas valve as a precaution. We clean sensors, test them, and replace igniters with OEM parts.
Gas Valve and Safety System Checks
Because gas furnaces burn fuel inside your home, we safety-check the gas valve, the manifold pressure, and the venting on every gas furnace repair call. A furnace that is venting improperly or burning rich is a carbon monoxide risk, so this check is never optional with our crew. If you ever smell gas, leave the house and call your gas utility first, then call us at (478) 400-5908 once the utility clears the scene.
Furnace Tune Up
Furnace Tune Up in Sandy Springs is the flat-price preventive service that runs $80 – $200 and is the single best way to avoid a no-heat night in February. The job takes 60 to 90 minutes and covers a full-point inspection, cleaning, and calibration of your heating system. Sandy Springs winters are not harsh by northern standards, but a furnace that fails on a 25-degree night is still a health risk for kids and older adults in the house. We recommend one tune-up in October and we book them on a schedule, so you are not calling us the morning of the first freeze.
What the Tune-Up Covers
Our tune-up checklist includes the ignition system, the gas valve, the heat exchanger, the blower motor, the condensate drain, the air filter, the thermostat calibration, and a full carbon monoxide check. We clean the flame sensor, the burners, and the blower wheel, and we test the system’s amp draws against the manufacturer’s spec sheet. You get a written report listing what we found and what, if anything, needs attention.
When to Schedule in Sandy Springs
Schedule your tune-up before Thanksgiving if you can. Once December hits and furnaces start failing across Roswell, Dunwoody, and Chamblee, emergency calls crowd the schedule and make it hard to get a preventive visit. A tune-up also keeps your warranty valid on many brands, including Carrier and Daikin, which require annual maintenance as a condition of parts coverage.
Emergency Furnace Repair
Emergency Furnace Repair in Sandy Springs means a furnace that fails when you need it most, on a freezing night or a weekend, and we answer that call with a live person 24/7 at (478) 400-5908. Most emergency furnace repairs run $150 – $700 depending on the part, and we do not charge overtime for nights or weekends. The Garrison Standard says a real person answers the phone, a technician arrives inside the stated window, and the price is in writing before any work begins, no exceptions, no matter the hour. In Sandy Springs, a no-heat situation during January is not just uncomfortable; it is a safety issue if the house gets cold enough to risk frozen pipes.
What Counts as an Emergency
No heat during freezing weather is an emergency, especially if small children, elderly adults, or anyone with respiratory problems lives in the house. A furnace that is banging loudly, short cycling constantly, or producing a smell of gas also warrants an immediate call. If you smell gas, leave the house and call your gas utility first; once the scene is clear, call us to repair the furnace itself.
Overnight and Weekend Response
Our Sandy Springs crew runs overnight and weekend dispatch, and the technician who arrives is background-checked, uniformed, and driving a marked Dalton Heating & Air vehicle. The price is the same as a weekday call, in writing before the repair starts. The written guarantee is the same too: if the fix does not hold for a full year, we return at no charge.
Brands We Service
We’re factory-trained to service nine major residential HVAC brands, and our Sandy Springs technicians have deep bench experience with Carrier and Bryant specifically. Carrier and Bryant share a parent company and a common design language, so a technician who can diagnose one can usually read a wiring diagram for the other without guessing. We stock common OEM parts for both, which means fewer return trips waiting on a part to ship. American Standard is another brand we see regularly in Sandy Springs, especially in older homes where the furnace was installed and well-maintained for 15-plus years. On those systems, we check the heat exchanger carefully, because that is the component that determines whether a 12-year-old American Standard is worth repairing or has reached the end of its serviceable life.
Daikin units show up more in newer construction around North Atlanta and Chamblee, and our techs work on their variable-speed and multistage gas furnaces, which are more complex than single-stage units but respond well to the same diagnostic discipline. Whatever make you have, whether it is Daikin, Bryant, American Standard, Carrier, or any other nameplate, our process is the same: diagnose first, price in writing, repair by the book, and stand behind it for a year.

- Furnace runs but won’t heat. When the blower moves air but the air is cold, the problem is usually the igniter, gas valve, or flame sensor. A furnace in this state runs constantly, burns electricity, and never reaches your set temperature, which pushes your utility bill up while your house stays cold.
- Short cycling. When the furnace turns on and off every few minutes, the system is overheating or detecting a pressure fault and shutting down for safety. Short cycling stresses the blower motor and the igniter and usually points to a blocked filter, a failing limit switch, or a heat exchanger problem.
- Loud banging, popping, or rattling. A banging noise at startup often means delayed ignition, where gas builds up in the burner chamber before the igniter fires. Popping can signal an expanding and contracting heat exchanger, which over time leads to cracks. Both are safety-significant and worth a same-day call during heating season.
- Smell of gas or exhaust fumes. A natural gas smell means get everyone outside and call your gas utility first. A musty or metallic exhaust smell, especially when the furnace first fires, can indicate a cracked heat exchanger venting combustion gases into the house. This is the one failure pattern we treat with the highest urgency in Sandy Springs homes.
- Yellow flame instead of blue. A healthy gas furnace burns with a clean blue flame. A yellow, flickering flame means incomplete combustion, which produces carbon monoxide. It can result from a dirty burner, a blocked flue, or insufficient combustion air, and all three are the kind of problem a professional can correct in one visit.
Our Process, Step by Step
- 1
You call, a person answers. When you call (478) 400-5908, a live dispatcher picks up, 24/7. We take your address, your system type, and what you are seeing, and we give you a real arrival window, not a four-hour block. If it is an emergency, we tell you plainly when the truck will arrive.
- 2
The technician arrives and verifies the problem. The technician shows up in uniform, background-checked, and driving a marked Dalton vehicle. Before touching anything, he or she asks what changed, walks the system, and confirms the symptoms you described. We do not start guessing and we do not start work without your sign-off.
- 3
Diagnosis with meters and tools. We diagnose with a multimeter to check electrical continuity, a manometer to measure gas pressure, and a combustion analyzer to read the burner’s efficiency and CO output. The diagnosis isolates the exact failed part, so the price we quote is for the actual repair, not a hopeful guess.
- 4
Written price before any work begins. Before the technician opens the toolbox, you get the repair price in writing. That price covers the part, the labor, and the time on site. It does not change after the work starts. If the diagnosis finds multiple problems, you see all of them and choose what gets fixed now.
- 5
Repair, test, and written guarantee. The repair is done by the book, the system is run through a full sequence, and the technician verifies the temperature rise and burner readings match manufacturer spec. Before leaving, you get a written guarantee covering the repair for a full year, not 30 days, and if it fails in that time, we return at no charge.
How Much Does Furnace Repair Cost in Sandy Springs?
Furnace repair in Sandy Springs runs $150 – $700, with most jobs landing between $200 and $450. The cheapest common repairs are flame sensor cleaning, igniter replacement, and pressure switch swaps, which typically run $150 – $250 including the part and labor. Mid-range repairs include blower motor replacement, gas valve work, and control board troubleshooting, which land in the $250 – $450 range. The high end, $450 – $700, covers heat exchanger replacements when they are worth doing, variable-speed blower motors, and certain Daikin or Carrier control modules that cost more in parts.
What affects the price? The part itself is the biggest variable; an American Standard igniter costs less than a variable-speed control board for a newer Daikin. Access matters too; a furnace in a tight attic or crawlspace adds labor time. The age of the system matters; parts for a 20-year-old furnace can be harder to source, though we stock the common ones. To avoid overpaying, get the price in writing before work starts, and ask what the warranty on the part is. Every Dalton Heating & Air estimate is free, written, and covers diagnostics, so you are never paying to find out what is wrong. Call (478) 400-5908 and we’ll walk you through the numbers honestly.

Frequently Asked Questions About Furnace Repair in Sandy Springs
Furnace repair is the diagnosis and fixing of any component in a forced-air heating system that prevents it from safely producing and distributing warm air. The work ranges from cleaning a flame sensor to replacing a blower motor or heat exchanger. A trained technician isolates the failed part, prices the fix in writing, and completes the repair with a written guarantee on the work.
Most furnace repairs in Sandy Springs take 60 to 90 minutes once the technician begins work, with diagnosis adding another 45 minutes on top of that. The exact time depends on the part: an igniter or flame sensor is under an hour, while a heat exchanger replacement can take most of a day. If access to the furnace is tight, like an attic pull-down in a Dunwoody ranch home, that adds labor time.
Most furnace repairs run $150 – $700, with the typical call landing between $200 and $450 depending on the failed part. Simple fixes like a flame sensor or pressure switch sit at the low end, while blower motors, gas valves, and control boards run higher. The price is always in writing before work starts, and the estimate is free. Call (478) 400-5908 for an exact quote.
