Lennox Air Duct Cleaning Service Nationwide

Why Orlando Homeowners Choose Lennox Air Duct Cleaning

We provide independent Air Duct Cleaning services for Lennox systems in Orlando, and what sets our work apart is that we clean to the airflow design of your specific Lennox system. In Orlando’s climate, a Lennox variable-speed blower can push dust into corners of supply ducts that a generic cleaning never reaches. We service Trane and Carrier systems too, but this page is for Lennox owners who want a forced-air clean that matches how their equipment actually moves air.

Paul Adeyemi founded Mortons Air Duct Orlando in 2005, and he learned HVAC technology at Los Angeles Trade-Technical College before spending the better part of two decades inspecting and cleaning duct systems across the Orlando area. His crews know where Lennox plenums, flex runs, and return drops collect the most fungal and particulate matter in this humid, pollen-heavy environment. We are not affiliated with or authorized by Lennox. We are an independent Lennox service provider, which means we answer to you, not to a manufacturer’s service network.

Why Trust Mortons Air Duct Orlando for Your Lennox Air Duct Cleaning?

Our technicians work on Lennox in Kissimmee and Orlando duct systems in these specific conditions every week, so they know the equipment’s anatomy. They can identify a Lennox Elite Series EL296V variable-speed furnace by its blower housing and know that its long, low-CFM run cycles leave dust in places single-stage systems never reach. They know the Signature Series SLP99V modulating furnace moves air so gently that fine particulate settles inside supply runs when return filtration is not kept up. And they know the Merit Series ML180E, common in Orlando’s 1990s and 2000s tract homes, often sits in a hot attic where flex duct insulation breaks down and allows condensation inside the liner.

This is not generic knowledge. Paul built Mortons Air Duct Orlando on one straightforward idea: tell the customer exactly what you found, exactly what you plan to do about it, and exactly what the invoice will say before a single piece of equipment comes off the truck. He is probably best known for taking his time. His crews rarely rush a job, and clients often mention that he noticed something a previous company missed. That matters when you own a communicating Lennox system where a crushed return elbow or a torn flex run can trigger “poor airflow” on the iComfort thermostat.

Common Lennox Air Duct Cleaning Problems We Fix in Orlando

• Heavy dust buildup behind the filter rack on variable-speed Lennox systems. The EL296V and SLP99V blowers run at low CFM for long cycles, which is efficient but allows fine dust to settle in supply ducts if the return filter is not changed on schedule. We often find heavy accumulation packed into the first several feet of every supply run leading from the plenum, especially on systems where Orlando’s sandy construction dust works its way past the filter gasket.
• iComfort thermostat “poor airflow” warnings from crushed or kinked flex duct. Lennox iComfort communicating thermostats report poor airflow when return ducts are partially obstructed. In Orlando, we trace this to flex duct kinks near the air handler, crushed metal elbows, or original 1990s flex runs that have been pinched by stored boxes in the attic.
• Microbial growth on Lennox evaporator coils in Orlando’s humidity. Orlando’s long, rainy summers mean condensation sitting on coil surfaces for months. On Lennox systems, that humidity-driven microbial growth sends musty odors through the ducts. We address the coil and the adjacent supply plenum together, because cleaning only one leaves the other ready to recontaminate the system within a season.
• Dust bypass through clogged Lennox Healthy Climate media cabinets. Lennox Healthy Climate UV lamps and media air cleaners trap more spores than standard filters, but when the pre-filter clogs, airflow drops and dust bypasses the media into the supply ducts. We see this on systems with deferred filter changes in Orlando homes with pets and high pollen loads from live oaks.
• Attic insulation pulled into Lennox supply plenums through takeoff gaps. In Orlando’s suburban tract homes, original duct board and takeoffs develop small gaps over years of attic heat cycling. We find fiberglass insulation particles inside supply ducts where those gaps act like a vacuum under negative pressure, and we seal them with mastic after cleaning so the problem does not return.

Lennox Parts & Our Repair-vs-Replace Approach

When we seal or repair Lennox duct fittings, access doors, and filter racks, we use OEM-equivalent replacements, not generic hardware. For duct board and flex, we match the original insulation R-values rather than chasing brand names, because the R-value is what keeps Orlando’s attic heat from condensing moisture inside the liner. For Lennox repair in Clermont and Orlando, where a flex run has been crushed or torn, we repair first if the inner liner is still intact. We recommend replacement only when the duct is saturated, moldy, or collapsed beyond repair.

Our local stock includes common Lennox filter rack sizes, mastic sealant, flex duct in typical Orlando residential diameters, and access door hardware. That means we can usually complete a repair during the same visit as the cleaning, without scheduling a return trip for a part. Call (321) 204-8194 for a written price before any work begins.

Our Lennox Service Process – Step by Step

1. 1
   Diagnosis. We inspect the full Lennox duct path from return grilles to supply registers, paying attention to plenum takeoffs, filter rack fit, and any sections where flex duct passes through hot attic spaces. We use video inspection when needed and show you what we find.
2. 2
   Repair and sealing before cleaning. If we find crushed flex, takeoff gaps, or a torn access door, we repair those first, because cleaning a leaky system pulls attic air into the ducts the moment the blower restarts. We seal takeoffs and plenum joints with mastic sealant, not tape.
3. 3
   Duct cleaning with professional equipment. We use Rotobrush and Nikro HEPA vacuum systems with agitation whips matched to your Lennox duct diameters. Variable-speed Lennox systems get extra attention on the first several feet of each supply run, where fine dust settles at low CFM.
4. 4
   Testing and warranty. We test airflow at the registers and confirm the iComfort thermostat, if present, reads normal. Every job is backed by the 365-Day Done Right Promise: if the job is not right, we make it right.

Lennox Products We Service & Install in Orlando

We clean and service duct systems connected to Lennox Elite Series (EL296V, XC and XP heat pumps), Signature Series (SLP99V, SLP98V), and Merit Series (ML180E, ML193) equipment. We work with Lennox Healthy Climate filtration and ventilation systems, including media air cleaners and UV lamps, and we size duct sealing and replacement to match your Lennox blower’s static pressure requirements in Orlando’s tight suburban attics. We also stock common filter rack dimensions across Lennox residential lines so a repair does not turn into a multi-day wait.

We Also Service These Brands

While this page focuses on Lennox, our Orlando crews clean and service duct systems on Trane and Carrier equipment as well. If you have a mixed system or are unsure what you have, call (321) 204-8194 and we will tell you what we find and what it costs before we start.

FAQs – Lennox Air Duct Cleaning Service in Orlando

Why does my Lennox variable-speed furnace leave dust in the ducts even though we change the filter?

Lennox variable-speed blowers, like the EL296V and SLP99V, run at low CFM for long cycles by design. That low airflow means fine dust that makes it past the filter settles inside the supply ducts instead of being blown out. In Orlando, where the AC runs nearly continuously from April through October, the long run times increase this effect. Adding a better return filter helps, but a periodic supply duct cleaning focused on the first several feet of each run is the real fix. Call (321) 204-8194 and we will inspect your system and give you a written price.

My Lennox iComfort thermostat says ‘poor airflow’ – is that a duct problem?

Often, yes. The iComfort communicating thermostat reads static pressure and airflow, and a warning frequently traces to a crushed or kinked flex duct, a saturated return filter, or a collapsed elbow near the air handler. We find this regularly in Orlando homes with original 1990s flex runs in the attic. We check the return path first, then the supply plenum, and we show you what we found before any work starts.

Lennox evaporator coils in Orlando get moldy fast – should I clean the coils before the ducts?

Yes, generally clean the coil first. In Orlando’s humid subtropical climate, microbial growth on the evaporator coil sends musty odors through the ducts, and cleaning the ducts without addressing the coil means the system recontaminates within a season. We clean the coil and the adjacent supply plenum together, using equipment from Nikro and Abatement Technologies where needed. This sequenced approach keeps the ducts clean longer.

Do Lennox Healthy Climate UV and media air cleaners reduce the need for duct cleaning?

They reduce particulate load and spore counts inside the ducts, but they do not eliminate the need for cleaning. When the pre-filter in a Healthy Climate media cabinet clogs, airflow drops and dust bypasses into the supply ducts. In Orlando homes with pets, high pollen, and construction dust, we still recommend periodic supply duct cleaning even with these systems installed. We can assess your system’s actual dust load with a video inspection and tell you when it is time.

How do you clean the supply ducts on a Lennox system with many small flex runs?

We use Rotobrush and Nikro equipment with agitation whips sized to the small-diameter flex runs common in Orlando tract homes. We do not try to push one large brush through a six-inch flex run. We also seal the takeoffs at the plenum with mastic after cleaning, because small flex systems often leak at the connections and pull attic air into the airstream.

How much does Lennox air duct cleaning cost in Orlando?

For a typical Orlando single-family home with a Lennox system, whole-system air duct cleaning generally runs between $450 and $850, depending on the number of returns, supply runs, and whether evaporator coil cleaning is included. Homes with collapsed or moldy flex runs will be quoted for additional repair work separately and always in writing before we begin.
