AfterLennox Air Duct Cleaning in Tampa, CA | Hollis Air Duct Cleaning
Air Duct Cleaning in Tampa for a Lennox system typically runs $450 to $900 for a full system, and we complete most jobs in half a day. We’re an independent provider, not factory-authorized, but we’ve worked on Lennox equipment across Tampa’s humid subtropical climate long enough to know exactly where these systems fail. If your Lennox air handler is in a Tampa attic, the ductwork and coil are fighting moisture year-round. Call (361) 326-5060 for a written estimate before any work starts.
Why Tampa Residents Choose Us for Lennox Service
Roy Castellanos, our owner, learned HVAC fundamentals through the sheet metal and air conditioning program at Los Angeles Trade-Technical College and spent years doing hands-on duct work before starting Hollis Air Duct Cleaning. That background matters when we open a Lennox air handler in a Tampa attic and find the gasket has turned to crumbs. We know what we’re looking at.
We’re independent, so our recommendation isn’t tied to a manufacturer sales target. We stock OEM Lennox gaskets and coil-compatible parts where they matter, and we use aftermarket flex duct, mastic, and insulation that meet or exceed factory specs where duct repair is the smarter fix. Our techs are background-checked and uniformed. The price is written down before we touch anything. And if it’s not done right, our 365-Day Done Right Promise means we come back at no charge. For broader context on how we approachLennox sales & service, that’s the same standard we apply to every duct system we open in Tampa.
Common Lennox Air Duct Cleaning Problems We Solve in Tampa
- Louvered cabinet doors pulling attic dust. Lennox air handlers with louvered doors rely on a perimeter gasket. In Tampa’s attic heat, that gasket degrades fast, and the blower starts pulling insulation fibers and fine dust straight across the evaporator coil. We replace the gasket, clean the blower wheel and coil, and the airflow restriction drops immediately.
- Flex duct connectors separating at the plenum. Year-round condensation plus thermal cycling in a hot Tampa attic is hard on flexible duct collars. We regularly find Lennox systems where the connector has torn or slid off the plenum, dumping conditioned air into the attic. That’s a duct repair job, not just a cleaning.
- Condensation pooling in slab-on-grade ductwork. Many Tampa homes sit on slab foundations with ducts running under the concrete. When hurricane season pushes groundwater up, or the original duct insulation gets compromised, condensation pools inside those under-slab runs. That’s where microbial growth starts, and it’s one reason Tampa duct cleaning often involves more than dust removal.
- Formicary corrosion on evaporator coils. Lennox coils with tin-plated copper tubing are susceptible to formicary corrosion in humid, coastal air like Tampa’s. Tiny pinholes leak refrigerant, the coil runs cold, and condensation increases throughout the duct system. We’ll flag this during a coil cleaning and give you an honest repair-or-replace assessment.
- Undersized returns in older homes. In Seminole Heights and Hyde Park, original ductwork was often sized for gravity furnaces, not modern Lennox AC. Oversized systems on undersized returns pull humid air from wherever they can find it. We see this constantly in Tampa’s historic bungalows.
Lennox Service in Tampa: What Local Conditions Mean for Your Equipment
Tampa’s historic bungalows in Seminole Heights often have original ductwork sized for gravity furnaces, not modern air conditioning. When a homeowner upgrades to a Lennox Merit or Elite Series system without addressing the duct sizing, the return side starves. That negative pressure pulls humid attic air through every seam and gap in the return duct, which condenses on the coil and drips into the cabinet. We rarely see this combination of factors in newer suburban construction around Tampa; it’s a specific problem of the pre-1950 housing stock. What it means for Lennox owners is this: a coil cleaning alone won’t fix a system that’s pulling attic air through a collapsed return. You have to correct the return before the cleaning means anything. That’s the kind of thing we check on every Tampa job before we give you a price. For everything we cover, see ourTampa service area.
We were called to a 1920s bungalow in Seminole Heights where the homeowner’s Lennox Elite Series system was short-cycling and the house felt clammy. Our video inspection found the original return duct in the crawlspace had collapsed and was drawing humid attic air into the system. The evaporator coil was caked with biological growth. We rebuilt the return with insulated flex duct, sealed the plenum with mastic, cleaned the coil, and the system’s static pressure dropped by 0.3 inches of water column. The homeowner said the air felt drier within hours. That’s what duct correction looks like in old Tampa construction.
Lennox Models & Products We Service in Tampa
We service the full Lennox residential lineup: the Merit Series (14ACX, ML14XC1), Elite Series (EL16XC1, EL18XCV), Signature Series (SL28XCV, SL25XPV), and the Dave Lennox Signature Collection (XC25, XP25). The ductwork attached to a Signature Series system isn’t fundamentally different from a Merit system; what changes is the cost of getting it wrong. High-efficiency Lennox equipment runs longer cycles, which means the ducts see more sustained airflow and more condensation opportunity. For critical cabinet components we use OEM Lennox parts when available. For duct repairs, we use aftermarket flex duct, mastic, and insulation that meet or exceed factory specifications because the ductwork aftermarket is genuinely better than factory flex. We’ll always tell you which is which and why.
Lennox Service Pricing in Tampa
A full Lennox air duct cleaning in Tampa runs $450 to $900 depending on system size, number of returns, and whether we’re cleaning the evaporator coil and blower wheel at the same time. Duct sealing adds $300 to $700 depending on accessible duct length. Flex duct repair runs $150 to $400 per section replaced. These are whole-system prices, not per-vent teaser rates. You get the number in writing before we start, and it does not move at the door. Call (361) 326-5060 and we’ll give you a straight answer.
Key takeaways:
- Independent Lennox service, not factory-authorized; we recommend what the equipment actually needs.
- OEM Lennox parts for critical cabinet components; aftermarket flex and mastic for duct repairs where they outperform factory.
- One written price per system before work begins; covered by a 365-Day Done Right Promise.
- We check duct sizing and return integrity before cleaning, because Tampa’s old homes punish that oversight.

FAQs – Lennox Air Duct Cleaning in Tampa
Yes, and it’s one of the first things we check. A clogged evaporator coil or a collapsed return duct forces your Lennox system to run longer to hit the thermostat setpoint. In Tampa’s humidity, that translates to more moisture pulled into the ducts and more biological growth. Once we clean the coil, rebuild the return, and seal the plenum, the system stops working so hard. Call (361) 326-5060 and we’ll tell you exactly what your system needs.
Louvered Lennox air handler doors are common in Tampa attics, and their gaskets fail faster here because of the heat. During a cleaning we pull the blower, inspect the gasket, and replace it if it’s degraded. That’s a step a generic Tampa Dryer Vent Cleaning crew skips, and it’s the difference between a system that stays clean and one that re-contaminates itself within a season.
The cleaning process itself is the same rotary brush and negative-air method we use on all systems. What changes with Signature Series equipment is the stakes: these units run longer cycles and modulate, so any duct leakage costs you more in energy and comfort. We’re more aggressive about recommending duct sealing on premium Lennox systems because the payback is faster.
Yes. During hurricane season, Tampa’s water table rises enough to saturate the soil around slab-on-grade homes. Ducts running under the slab can wick that moisture even if no water ever enters the living space. We look for condensation staining, rust on the register boxes, and musty air from specific supply vents. If we find it, we’ll show you the video before we recommend anything. For a written quote, call (361) 326-5060.
Older Tampa homes in Seminole Heights and Hyde Park often have ductwork that was never designed for the Lennox equipment now attached to it. The return side is undersized, the seams are loose, and the system pulls humid air from the attic or crawlspace. Duct sealing with mastic, plus return correction where needed, reduces that infiltration and stabilizes the system. It’s one of the highest-value services we perform in Tampa’s historic districts. Estimates are free, so call (361) 326-5060.
