Lennox AC installation in Sandy Springs typically costs between $3,500 and $7,500 for a complete system, depending on the model line and the condition of your existing ductwork. We provide independent Lennox AC installation across Sandy Springs, which means we source equipment directly and handle every step from load calculation to final cleanup. Most Lennox installs take one full day, sometimes two if we’re reworking duct connections in older homes near the Chattahoochee. We give a written price before any work starts, so you’ll know the exact number before a single piece of equipment arrives. If you’re a Lennox owner researching replacement or first-time central air, call (229) 490-2049 and a live person will talk through your situation.
How Lennox Products Fail – and How We Fix Them
After nearly two decades working on Lennox systems across the Southeast, we see patterns that are specific to the brand. Here’s what actually happens out in the field, and what we do about it when it shows up during an AC installation job.
- Evaporator coil leaks on the Merit series. The Merit line is Lennox’s entry-level equipment, and the evaporator coils on units that have run hard through Sandy Springs summers tend to develop pinhole leaks at the copper-aluminum joints. If we’re installing a new condenser and find the existing coil leaking, we replace both. Pairing a new condenser with a worn coil is how you wind up with a six-month callback.
- Compressor bearing wear on the Elite series after 10 – 12 years. Elite units run quieter than Merit, but once the compressor bearings start to rattle on startup, the clock is ticking. During an installation quote, we listen for that startup sound, because it changes the math: a compressor replacement on an older Elite often costs close enough to a full install that replacement is the honest recommendation.
- Drain pan corrosion on indoor air handlers in older Sandy Springs homes. The humidity here means indoor coils sweat constantly. On Lennox air handlers from the early 2010s, the factory drain pans can rust through before the coil itself fails. If we’re doing new central air installation and the existing pan is compromised, we include a new pan in the scope rather than leaving a floor-protection problem for later.
- Control board communication issues on the Signature series. The Signature line uses Lennox’s proprietary communicating system. It’s efficient, but a misbehaving control board reads as a system-wide fault. When we install a Signature system, we verify every communication wire is seated and flashed to the latest firmware before we call the job done, because an intermittent board error is the last thing you want at 9 p.m. in July.
- Incorrect refrigerant charge from previous installs. This isn’t a Lennox manufacturing defect, but it’s a Lennox-specific field problem: these units are sensitive to overcharge. A system with 8 ounces too much R-410A runs hot and eats compressors. Before we install anything, we recover the old refrigerant and weigh it, because what we find tells us how the last install was done and what the new system needs to run right.

Our Lennox AC Installation Process
Every Lennox installation in Sandy Springs follows the same sequence, whether it’s a Merit replacement or a full Signature upgrade. Luis Serrano built this process himself, and the crew follows it exactly.
- 1
Load calculation and duct inspection. We measure square footage, window orientation, and existing duct runs before recommending any Lennox model. In Riverside and the older streets near the river, duct sizing is often undersized for what the house actually needs.
- 2
Written price before anything is ordered. You get a fixed dollar amount covering equipment, labor, refrigerant, any new drain pan or duct adapters, and cleanup. No range. No “we’ll see what the job needs.”
- 3
Equipment selection and parts decision. We talk through OEM Lennox parts versus quality aftermarket where it matters, and which pieces we never substitute. If you want to understand the trade-offs, Luis walks you through them before you commit.
- 4
Installation day. The crew shows up in uniform, drops shoe covers and drop cloths before anything comes through the door, and keeps the workspace contained. If you have pets, we keep doors and gates closed so nobody makes a break for it.
- 5
Refrigerant charge verification and system test. We weigh in the exact spec of refrigerant, run the system through a full cycle, and check airflow and temperature drop at the vents. A Lennox system that’s charged correctly is quiet. One that’s off by a few ounces isn’t.
- 6
Cleanup photo and walkthrough. Before the crew leaves, we take a photo of the cleaned workspace and walk you through what was installed and why. The 365-Day Done Right Promise starts the day we leave, and if anything’s not right, we come back.

AfterWhat Lennox AC Installation Costs in Sandy Springs
Lennox AC installation in Sandy Springs runs $3,500 to $7,500 for most complete systems, which is the range we quote for central air installation and replacement. A Merit series install typically sits at the lower end, while Elite and Signature systems land in the upper half. Heat pump installation and mini split installation fall within the same general range, though multi-zone mini split work can push higher depending on the number of indoor heads.
Price moves based on three things: system size, ductwork condition, and accessibility. A straight condenser swap in a newer home on the north side of Sandy Springs costs less than a full install in a 1960s house where the duct plenum needs rebuilding. We write the price down before work starts, so you can plan around exact dollars, not vibes. Call (229) 490-2049 for a free estimate on your specific home. We’ll give you a number you can actually use.

FAQs
Most Lennox AC installations in Sandy Springs take one full day, though jobs that involve reworking existing ductwork or replacing a corroded drain pan can run into a second day. We’ll give you a clear timeline before we start, and we respect quiet hours if your family works or studies at home during the install.
Genuine Lennox parts are generally required to keep the manufacturer warranty intact, and we default to OEM parts for that reason. Where quality aftermarket parts make sense, we’ll explain the trade-off in plain language before you spend a dollar. Call (229) 490-2049 to talk through your specific scenario.
If your Lennox system is over 10 years old and a major component like the compressor or evaporator coil has failed, replacement is often the better financial decision, especially with Sandy Springs summers pushing systems hard. We’ll show you the repair cost and the install cost side by side so you can decide with real numbers.
Most common Lennox parts are available within a day or two through regional supply channels, but Signature series communicating boards can take longer depending on stock. We keep the most frequent failure items on the truck so a straight Merit or Elite repair doesn’t turn into a waiting game.
Yes. As an independent Lennox service provider, we install and service Lennox systems regardless of where the equipment was originally purchased.
