Lennox Air Duct Cleaning in Columbus, OH

Lennox Air Duct Cleaning in Columbus, CA | Hollis Air Duct Cleaning

We provide independent Columbus Air Duct Cleaning for Lennox systems, and the one thing that makes our work here different is simple: we know how Columbus’s split housing stock affects Lennox equipment. A 1920s Clintonville bungalow with original galvanized ducts and a brand-new Dublin flex-duct system are two entirely different jobs. If you’re running a Lennox furnace or air handler in Columbus, call (361) 326-5060 for a straight answer and a written price before any work starts.

As an independent company, we’re not tied to Lennox’s authorized network. That means we can recommend the right fix without a manufacturer script telling us what to sell. Roy Castellanos, our owner, came up through the sheet metal and air conditioning program at LA Trade-Tech and spent years doing hands-on duct work before starting Hollis. He’s the kind of person who would rather explain what we found in your ductwork than hand you a bill you don’t understand. We bring that same approach to every Lennox job in Columbus.

Why Columbus Residents Choose Us for Lennox Service

Columbus has a housing stock problem that most air duct companies don’t talk about. The older neighborhoods, Clintonville, the Short North, Olde Towne East, are full of pre-1950 homes with galvanized ducts that have never been properly cleaned. The newer suburbs, Dublin, Westerville, Pickerington, have flex duct that kinks, sags, and collects dust in ways that stress a Lennox blower. We work both sides of that divide every week.

Our techs carry OEM-equivalent aftermarket parts for Lennox blower motors, pressure switches, and coils when they meet spec. For critical components like heat exchangers and control boards, we recommend OEM to match Lennox’s exact tolerances. That’s the honest middle ground: affordable where it’s safe, exact where it matters. And every job gets a written price before we touch anything. No moving targets at the door.

We’re also part of the Garrison Partners family, running on The Garrison Standard. That means background-checked, uniformed technicians, a live person answering the phone around the clock, and the 365-Day Done Right Promise in writing on every job. If the work fails within a year, we come back at no charge. That’s not a slogan. It’s the way Roy built this company since 2004.

Common Lennox Air Duct Cleaning Problems We Solve in Columbus

• Rust ingestion in galvanized ducts. In pre-1950 Columbus neighborhoods, original galvanized ducts sweat internally during summer AC season. The rust flakes get pulled into Lennox air handlers and coat the blower wheel and evaporator coil. This is the single most common problem we see in Clintonville and Olde Towne East.
• Static pressure stress on variable-speed blowers. Lennox Signature and Elite variable-speed blowers are sensitive to static pressure. Kinked or poorly sized flex duct in Dublin, Westerville, and Pickerington slab and attic layouts forces the blower to run at high RPM constantly. That trips pressure switches and shortens motor life.
• Biological growth in Healthy Climate media cabinets. Columbus’s humid summers turn Lennox Healthy Climate filters and HRV/ERV cores into biological growth sites when return ducts aren’t sealed. Homeowners notice a musty odor that doesn’t go away. The fix is sealing the return side and cleaning or replacing the media.
• Clogged evaporator coils from decades of dust. Older Lennox Complete Heat HM30 and HM40 systems in Columbus city neighborhoods often have undersized return drops. When ducts are full of decades of debris, the coil gets starved, the heat exchanger runs hot, and efficiency drops hard.
• Debris-filled blower assemblies. After years of pulling central Ohio pollen, mold spores, and dust through leaky returns, Lennox blower wheels collect a layer of grime that throws them out of balance. We clean the blower and housing, then seal the return so it stays clean.

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

Here’s the thing about Columbus that no generic Lennox page will tell you. The city’s pre-1950 housing stock, concentrated in Clintonville, the Short North, and Olde Towne East, is full of original galvanized ducts that sweat internally during AC season. That condensation causes rust flaking inside the ductwork itself. When a Lennox air handler pulls air through those ducts, it drags rust flakes and scale right into the blower wheel and evaporator coil. You will not find this in the newer flex-duct suburbs like Dublin or Westerville, where the ducts are plastic and the problems are kinks, sags, and installer error. In Columbus, the age of your neighborhood tells you which failure mode you’re likely dealing with before we even open the first access panel.

We saw this exact scenario in a 1920s Clintonville bungalow. The original galvanized supply trunk was flaking rust into a Lennox EL296V furnace, clogging the secondary heat exchanger and the blower wheel. Our tech did a full system clean, sealed the trunk with mastic, and installed a Healthy Climate media cabinet to catch remaining particulates. The musty odor disappeared and static pressure dropped back into spec. The homeowner said the system hadn’t run that quietly in years. That’s not a one-off. That’s a Tuesday in Columbus.
