Why Sandy Springs Homeowners Choose Lennox Air Duct Cleaning
Hollis Air Duct Sandy Springs provides independent Lennox Air Duct Cleaning in Sandy Springs, GA, duct sealing, and flex duct repair throughout the area. We work on Lennox Elite Series, Merit Series, and Signature Collection systems every week, and we clean the whole airflow path, not just the registers. As an independent Lennox service provider, we are not affiliated with or authorized by Lennox, but our technicians know these systems well enough to spot the failure patterns that shorten blower life and spike utility bills in Sandy Springs homes. Call (229) 489-7780 for a written quote before any work begins.
Why Trust Hollis Air Duct Sandy Springs for Your Lennox Air Duct Cleaning?
Lennox builds tight, efficient air handlers. That’s a good thing, until dust, pet hair, and Sandy Springs humidity start loading up the evaporator coil and blower wheel. Tight clearances inside Lennox Signature Collection cabinets mean less room for debris to pass through, so the coil becomes a filter, and airflow drops faster than most homeowners expect. Our technicians work on these units constantly, and we know what a restricted Lennox system looks and sounds like before we even pull the panel.
Roy Castellanos, who runs our Sandy Springs operation, grew up in Los Angeles and picked up his trade fundamentals at Los Angeles Trade-Technical College before moving east and spending the better part of two decades pulling grime out of ductwork across the Atlanta metro. He and his crew know the Sandy Springs housing stock well, including the older split-levels near Hammond Park where original flex duct sags and separates after thirty years of attic heat. Roy’s rule is simple: a clean job site, a straight read on what the system actually needs, and no padded estimates. Clean ducts, straight answers, that’s the whole job.
Every Lennox job we do gets a written price before work starts, and every job is covered by the 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge. That includes a free second visit. No fine print, no negotiating.

Common Lennox Air Duct Cleaning Problems We Fix in Sandy Springs
- Dust and debris buildup on blower wheels and evaporator coils in Lennox Signature Collection systems. The Signature Collection air handlers are built with tight internal clearances for efficiency, but that same compact design means debris loads up fast on the blower wheel and evaporator coil. In Sandy Springs, where high humidity keeps dust sticky and stubborn, this buildup cuts airflow and forces the blower motor to work harder. We clean the coil and blower wheel in place with professional-grade equipment, not a hardware-store shop vac.
- Flex duct compression and kinking behind Lennox Elite Series supply plenums. Sandy Springs attics get brutally hot in summer, and flexible duct that was installed decades ago loses its shape. We regularly find kinked or compressed flex duct behind Elite Series supply plenums, which starves individual rooms of air. The result is uneven temperatures between floors, and a system that runs longer than it should. We pull the flex back into shape, replace sections that have collapsed, and seal connections properly.
- Return duct leaks at mastic joints feeding Lennox Merit Series air handlers. Mastic joints dry out and crack over time. In Sandy Springs, leaky return ducts pull attic insulation, pollen, and humid air straight into the system. Homes near the Chattahoochee River corridor, especially in neighborhoods like Riverside and Heards Ferry, deal with persistent dampness that makes this problem worse. We test return-side integrity, reseal joints with fresh mastic, and stop the system from inhaling attic air.
- Condenser coil lint and pollen buildup on outdoor Lennox units. Sandy Springs has a dense tree canopy, and in spring the pollen load is heavy. Outdoor Lennox condensers in wooded neighborhoods collect a layer of lint and pollen that reduces heat exchange efficiency. The unit still runs, but it runs longer and draws more power. We include outdoor coil inspection and cleaning as part of a full-system Lennox service, because cleaning the inside of the ducts while ignoring the outdoor coil only solves half the problem.
- Mold and mildew growth inside duct runs and plenums. Sandy Springs sits in the Chattahoochee River corridor, and the humidity here is relentless. Condensation forms inside duct runs and plenums, especially in crawlspace-mounted air handlers with poorly sealed return ducts. That moisture feeds mold and mildew, which then circulates through the home every time the blower runs. We address the root cause, sealing leaks and correcting airflow, then clean the affected surfaces with professional-grade equipment.
Lennox Parts & Our Repair-vs-Replace Approach
We use factory-style replacement flex duct, mastic, and insulation that match Lennox duct specifications. That matters because generic, thinner flex duct collapses faster under Sandy Springs attic heat, and the wrong mastic fails early. When a coil or blower genuinely needs replacement, we recommend OEM Lennox parts. We do not push aftermarket coils or blower motors just to lower the bid, because a cheaper coil that leaks or a blower that runs hot costs more in the long run. The honest truth is this: most Sandy Springs Lennox systems we work on do not need new parts at all. They need deep cleaning, sealing, and airflow correction. We will tell you when replacement is actually required, and we will tell you when it is not. Call (229) 489-7780 if you want a straight answer on whether your Lennox system needs parts or just a proper cleaning.
Our Lennox Service Process – Step by Step
- 1
Diagnosis. We inspect the full airflow path, from return grilles to supply registers, with a focus on Lennox-specific weak points: coil condition, blower wheel buildup, flex duct integrity, and return-side leaks at mastic joints. We measure static pressure and airflow where the system configuration allows it.
- 2
Cleaning and seal. We use negative-air machines and rotary brush systems from Rotobrush and Nikro to pull debris out of the ductwork without blowing it into the living space. Evaporator coils get cleaned with a HEPA vacuum and coil comb. Flex duct gets pulled back into shape or replaced with factory-style material. Mastic joints get resealed.
- 3
Verification. After the work is done, we measure airflow again. One recent job off Riverside Drive involved a Lennox Elite Series air handler that had been cycling its blower on high for months. The return flex had sagged and kinked, and the evaporator coil was caked with dust and dog hair. After we pulled the flex back into place, sealed the plenum with mastic, and cleaned the coil, airflow jumped from 32% to 88% of rated CFM. That is a measurable result, not a vague promise.
- 4
Warranty. Every Lennox service we do is covered by the 365-Day Done Right Promise in writing. If something fails within a year, we come back and make it right at no charge. That is a free second visit, included on every job.

AfterLennox Products We Service & Install in Sandy Springs
We service ductwork and airflow systems connected to the full Lennox residential lineup: the Merit Series, the Elite Series, the Signature Collection, and the Dave Lennox Signature Collection. That includes air handlers, evaporator coils, condenser units, supply and return plenums, and all associated flex duct and rigid ductwork. We keep factory-style flex duct, mastic, and insulation on the truck for common Lennox repair jobs, so most fixes happen the same day in Sandy Springs without waiting on a parts order.
We Also Service These Brands
Hollis Air Duct Sandy Springs is not tied to a single manufacturer. Alongside Lennox, our technicians work on Trane and Carrier systems regularly. The airflow principles are the same: clean coils, sealed ducts, proper static pressure. If your home has a mixed system or you are not sure what brand is in the attic, we can identify it and service it the same visit.
FAQs – Lennox Air Duct Cleaning Service in Sandy Springs
No. We are an independent Lennox service provider, not a Lennox-authorized dealer. That means we are not bound by manufacturer service quotas, and we recommend only the work the system actually needs. We use factory-style materials that match Lennox specifications and OEM Lennox parts when replacement is genuinely required.
For replacement coils, blowers, and other mechanical components, yes, we recommend OEM Lennox parts. For flex duct, mastic, and insulation, we use factory-style materials that match Lennox duct specifications because that is what holds up in Sandy Springs attics. We do not use thinner, generic flex duct that collapses after one summer.
A typical Lennox system in Sandy Springs takes four to seven hours to clean and seal properly, depending on the number of returns, the condition of the flex duct, and whether the evaporator coil needs a full cleaning. Homes with crawlspace-mounted air handlers or severely degraded flex duct can take longer. We give you a written time estimate before work starts, and we hold to it. Call (229) 489-7780 for an exact time range for your home.
We service ductwork and airflow systems connected to Lennox Merit Series, Elite Series, Signature Collection, and Dave Lennox Signature Collection equipment. That covers the vast majority of Lennox residential systems installed in Sandy Springs homes over the past thirty years, including original flex duct from the 1980s and 1990s that is now degrading.
No. Routine Air Duct Cleaning services, coil cleaning, and duct sealing do not void a Lennox equipment warranty. In fact, Lennox’s own documentation identifies restricted airflow as a cause of premature component failure. What does void warranties is improper cleaning that damages the coil or blower. We use professional-grade equipment designed for the job, and we document the work we do. If a warranty claim ever comes up, you will have a record of proper maintenance.
For a typical single-family home in Sandy Springs, full Lennox system cleaning including duct cleaning, evaporator coil cleaning, and blower wheel cleaning runs roughly $700 to $1,400 depending on the number of returns, system size, and whether flex duct repair or duct sealing is needed. Homes with multiple zones or a second air handler run higher. We give a written price before any work starts, and that price does not move at the door. Call (229) 489-7780 for a free estimate, and we will give you a real number, not a teaser.
