Meadowsweet Heating and Air Alpharetta is an independent Lennox service provider. We are not manufacturer-affiliated or an authorized Lennox dealer, which means our only loyalty is to the homeowner standing in the kitchen with us. We work across nine major equipment brands, and we handle Lennox sales & service with the same care we bring to every job: shoe covers on, drop cloths down, and a photo of the clean-up sent before we pull out of your driveway.

Why Alpharetta Residents Choose Us for Lennox Service

Luis Serrano, our owner, trained at Los Angeles Trade-Technical College and spent close to two decades learning what Georgia humidity does to coils and ductwork from the inside out. That matters when you own a Lennox in Alpharetta, because a condensing furnace or variable-speed compressor behaves differently here than it does in a dry climate. If you’re dealing with cooling issues, our Alpharetta AC Repair team understands exactly how local humidity affects your system. Luis and our techs have worked regular routes through the Windward neighborhood long enough to recognize a failing Lennox evaporator coil before it floods your attic.

We stock OEM Lennox parts for warranty-covered components like variable-speed motors and control boards. For common wear items like capacitors and contactors, we offer quality aftermarket options that save you money without cutting corners. Every visit is backed by the Cedarwell Care Promise: a written price before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise. If it’s not done right, we make it right. No runarounds, no fine print. And yes, we wear shoe covers and lay drop cloths on every single job, because your floors matter as much as your airflow.

Common Lennox HVAC Problems We Solve in Alpharetta

• Iced-up coils in late-1990s Lennox Merit systems. Undersized returns in original Windward lakefront homes force the evaporator coil to run colder than designed. That leads to chronic coil icing, poor humidity control, and eventual compressor strain. We fix the airflow problem, not just the symptom.
• Failed control boards on Elite XC16 outdoor units after lightning storms. Alpharetta’s summer thunderstorms send surges through the power grid, and we regularly see blown relays and shorted capacitors on Lennox XC16 two-stage compressors. The fix is usually a replacement board or capacitor, but the real protection is a surge suppressor we can add during the repair.
• SLP98V gas valve and inducer issues near Crabapple. Homes on natural gas lines in the Crabapple area sometimes see variable-speed gas valve failures or restricted venting from sulfidation. We check venting integrity and inducer operation, then replace only what failed.
• Clogged condensate drain lines in XC25 heat pumps. Alpharetta’s summer algae and heavy pollen load plug drain lines in attic air handlers fast. We regularly find water damage starting where a Lennox XC25 drain pan overflowed. Clearing the line and adding an algae treatment tab is part of every summer service call we make here.
• R-22 leaks on 20-year-old Lennox 10ACC and 13ACX units. These systems run long in Alpharetta’s long cooling season, and when a coil corrodes, the charge leaks out. We pressure-test with nitrogen to confirm, then give you a straight answer on repair versus replacement.

Lennox Service in Alpharetta: What Local Conditions Mean for Your Equipment

Here’s a fact about Alpharetta that shapes every Lennox call we run here: the Windward community has one of the highest concentrations of original Lennox builder-grade systems from the late 1990s in the entire Atlanta metro. That’s not true in Johns Creek, where builders mixed Carrier and Trane more evenly. It’s not true in Lawrenceville, where newer construction dominates. In Windward specifically, we know to check for corroded evaporator coils and undersized returns on the lakefront homes before we even open the air handler. Our tech pulled up to a home on Lakewind Court in Windward for a no-cool call on a 2001 Lennox 10ACC. The owner said the system ran all day but never dropped below 78°F. We found a corroded evaporator coil leaking R-22 and a failing dual capacitor. After a nitrogen pressure test confirmed the leak, we replaced the coil and capacitor, recharged the system, and added a return duct to fix the undersized airflow. The home now holds 72°F even on humid afternoons. That’s the kind of specific, neighborhood-level knowledge you won’t get from a national Lennox review site, and it’s exactly what an Alpharetta homeowner needs.

Lennox Models & Products We Service in Alpharetta

We service the full Lennox lineup found across Alpharetta’s housing stock. That includes the Dave Lennox Signature Collection (SLP98V variable-speed furnace, XC25 heat pump), the Elite Series (EL296V, XC16), and the Merit Series (ML196, 13ACX). We also work on Lennox Healthy Climate products like PureAir air purification and Humiditrol whole-home dehumidification. Our parts approach is specific: OEM Lennox parts for proprietary components like variable-speed motors and control boards, quality aftermarket parts for wear items like capacitors and contactors. For multi-zone Lennox setups with dampers and zone control boards, we troubleshoot the full system, not just the zone that’s complaining. In Alpharetta’s larger homes, a single failed zone damper can make the whole system look broken, and we trace it down properly.

Why do Lennox systems in Windward homes often freeze up in summer?

Lennox systems in Windward lakefront homes often freeze up in summer because the original late-1990s builder-grade installations had undersized return ducts. That restricts airflow across the evaporator coil, which drops the coil temperature below freezing. Combine that with Alpharetta’s high summer humidity and a slightly dirty filter, and the coil ices over fast. We fix it by adding return capacity where the home’s layout allows, cleaning or replacing the coil if it’s corroded, and verifying the refrigerant charge. Call (478) 606-5046 if your coil is frozen now. Estimates are free.

Can I still get R-22 for my older Lennox AC in Alpharetta?

Yes, R-22 is still available in limited and increasingly expensive quantities for older Lennox systems in Alpharetta, but it’s a temporary fix. Prices for R-22 refrigerant have risen sharply since production ended, and the cost of recharging a leaking system often exceeds the value of a 20-year-old 10ACC. We’ll give you both options: recharge with what R-22 we can source, or a repair-and-replace quote for a new high-efficiency Lennox that uses R-410A or newer refrigerant. Call (478) 606-5046 for an exact quote.

Do Lennox variable-speed furnaces handle Alpharetta’s humidity better?

Yes, Lennox variable-speed furnaces like the SLP98V and EL296V handle Alpharetta’s humidity better than single-stage units, because the variable-speed blower runs long, low-airflow cycles that pull more moisture from the air. When yours isn’t performing, our Furnace Repair in Alpharetta gets it running right. That’s a real advantage in Alpharetta’s long cooling season, where high latent loads make standard systems struggle. If you’re comparing a two-stage or variable-speed Lennox for an Alpharetta home, we’ll walk you through the humidity difference in dollars and comfort terms, not brochure language.

What causes the control board to fail on my Lennox XC16 outdoor unit after a storm?

Alpharetta’s summer lightning storms send voltage spikes through the power grid that overwhelm the XC16’s control board, especially the relay and capacitor circuits. The outdoor unit sits exposed to the same surges that hit your other electronics, but without protection. We see blown relays and shorted capacitors on Lennox XC16 units regularly after storm season. Replacing the board is straightforward, but adding a surge suppressor at the disconnect is what actually prevents it from happening again. Call (478) 606-5046 for a board inspection before the next bad storm rolls through.

How often should I clean my Lennox outdoor coil in Alpharetta’s pollen season?

In Alpharetta’s spring pollen season, a Lennox outdoor coil should be cleaned every 4 to 6 weeks from March through May. Pine pollen, oak pollen, and the fine red clay dust that blows through Alpharetta’s construction zones clog coil fins fast, which drives up head pressure and cuts efficiency. If you have a XC25 heat pump that runs year-round, the buildup is even worse. We include coil cleaning as part of our $80 – $200 tune-up, and we’ll show you a before-and-after photo of your coil so you can see exactly what came off it. Call (478) 606-5046 to schedule one before the next pollen wave hits.
