Dalton Heating & Air Sandy Springs is part of the Garrison Partners network, operating under The Garrison Standard since 2003.

If you need Lennox sales & service from a team that treats your system like the investment it is, we’re ready.
Why Sandy Springs Residents Choose Us for Lennox Service
Most homeowners don’t care whether the tech has a Lennox badge on his shirt. They care whether he can diagnose the problem correctly the first time and put the price in writing before turning a single bolt. That’s the standard Marco Benitez holds every call to. Marco cut his teeth in HVAC at Los Angeles Trade-Technical College and spent the better part of two decades working systems across the Southeast before settling in Sandy Springs. He’s the one walking homeowners through what failed, why it failed, and what it costs, in plain English.
We service every Lennox line you’re likely to have in Sandy Springs, from older 13 SEER single-stage units to the variable-capacity XC25 and XP25 platforms. We stock OEM Lennox parts where they matter most: inverter boards, gas valves, control boards, and thermostats. For non-critical components, we use exact-match aftermarket equivalents that meet the same spec at lower cost. Every repair includes a written guarantee for a full year. If it fails within that window, we return at no charge. That’s the 365-Day Done Right Promise, and it applies to every Lennox service call we run in Sandy Springs.

Common Lennox HVAC Problems We Solve in Sandy Springs
- iComfort S30 thermostat losing communication with the air handler. We see this constantly in Sandy Springs neighborhoods with heavy tree cover, where the condenser short-cycles and the communicating thermostat drops its signal. The fix is usually the communication wire, not the stat itself. We check both before quoting anything.
- XC25 inverter board failure after summer thunderstorms. The Chattahoochee corridor gets dramatic lightning events, and power surges are brutal on Lennox’s variable-speed inverter boards. Homes without a surge protector on the disconnect are the most vulnerable. If your XC25 just stopped cooling after a storm, this is the first thing we check.
- EL296V gas valve sticking after months of inactivity. Sandy Springs winters are mild enough that furnaces sit idle from March to November. When the first freezing night hits, gas valves that haven’t cycled in eight months can stick. The no-heat call on that first cold snap is practically a local tradition.
- Drain pan cracks on older Lennox air handlers in humid crawlspaces. Homes near the river, especially in the Riverside Drive corridor, run crawlspace humidity levels that eat through plastic drain pans over time. Cracked pans leak onto floors and into slab penetrations. It’s a straightforward replacement if caught early.
- Clogged condenser coils from spring pollen and riverbank foliage. Sandy Springs is green for a reason. Pollen season packs Lennox condensers with a yellow film that kills heat transfer efficiency, and overgrown riverbank vegetation makes airflow worse. We see units running 15 degrees hotter than they should because of this.
Lennox Service in Sandy Springs: What Local Conditions Mean for Your Equipment
On Riverside Drive’s steep lots, Lennox condensers often sit on decaying wooden platforms with restricted airflow from overgrown riverbank foliage. That combination drives up head pressure and kills XC25 inverter boards faster than anywhere else in Sandy Springs. We’ve pulled condenser platforms that were more rot than wood, held together by paint and wishful thinking. When the unit can’t breathe, the inverter works harder, runs hotter, and fails sooner. It’s not a design flaw in the Lennox, it’s a site condition. Part of every Riverside Drive service call is checking platform stability and foliage clearance around the condenser. If you live on a sloped lot anywhere in Sandy Springs, that platform is worth a look before July.
One field vignette worth sharing: our tech traced an XC25 short-cycling complaint on a Riverside Drive split-level to a clogged condenser coil. The backyard was so steep we had to rope the unit to a tree just to open the service panel. After cleaning the coil and replacing the iComfort S30 communication wire that had corroded from Chattahoochee humidity, the system held a 20-degree delta T. No new board needed. Just access, cleaning, and the right diagnosis. That’s the kind of call that separates a parts-swapper from a technician.
Lennox Models & Products We Service in Sandy Springs
We work on the full Lennox residential lineup, with deep hands-on time on the variable-capacity and communicating platforms most independent shops don’t see outside warranty work. The XC25 variable-capacity air conditioner, EL296V two-stage gas furnace, XP25 heat pump, and SLP98V variable-capacity gas furnace are all in our regular rotation across Sandy Springs, and Sandy Springs Heat Pump Installation is a core part of our work. That includes older Lennox systems from the early 2000s still running in ranch and split-level homes, often paired with original ductwork in slab or crawl spaces.
For parts, we take a straightforward approach: OEM Lennox components for critical electronics like inverter boards and gas valves, exact-match aftermarket equivalents for everything else where the spec is identical. We stock the most common Lennox parts locally so a Sandy Springs repair doesn’t wait on a warehouse three states away. If we have to order something unusual, we’ll tell you honestly when it lands before we schedule the callback.

| Furnace Repair | $150 – $700 |
| AC Installation | $3,500 – $7,500 |

An inverter board replacement on a steep Riverside Drive backyard, where we need to stage equipment and work around the terrain, runs higher.

FAQs – Lennox HVAC in Sandy Springs
Every 4 to 6 weeks from March through May, and again if you notice a yellow film building up on the coil fins. Sandy Springs pollen season is aggressive enough that a condenser can lose 20 to 30 percent of its heat transfer capacity in a month. A garden-hose rinse with the power off is all most systems need between professional cleanings. Call (478) 400-5908 if you want us to handle it, and we’ll quote it as part of a standard tune-up.
Yes, but only if the system is single-stage or two-stage. If you have a communicating variable-capacity Lennox like the XC25 or XP25, a standard thermostat won’t talk to the equipment properly and you’ll lose most of its efficiency. We’ll tell you honestly which camp your system falls into before recommending anything. If a standard stat works, it’s a lower-cost fix. If it doesn’t, we’ll quote an OEM iComfort replacement instead.
Usually it’s the gas valve starting to stick after months of inactivity, or a limit switch tripping because airflow is restricted. Sandy Springs furnaces sit idle through the long warm season, so the first cold snap reveals problems that have been dormant since March. We diagnose it in one visit, and the fix is usually under $300. Call (478) 400-5908 and we’ll get it sorted before the next freeze.
We do, and it’s some of our most common work. The 1960s through 1980s ranch homes that define much of Sandy Springs often put air handlers and ductwork in crawl spaces, where humidity from the Chattahoochee does damage over time. Drain pan cracks, corroded wiring, and rusted blower housings are all in a day’s work. We’ll get into the crawlspace, show you photos of what we found, and put the repair in writing before we start.
If the compressor and heat exchanger are sound, repair it. The XP25 is a strong platform, and 15 years in Sandy Springs conditions doesn’t automatically mean it’s done. We don’t push replacement unless the compressor has failed or the heat exchanger is compromised. A replacement XP25 installation runs $3,500 to $7,500 depending on size and existing ductwork, so repair usually makes sense if it buys you three more years. Call (478) 400-5908 and Marco will walk you through the numbers on both options, in writing.
