Cleaning & Care
Air Duct Cleaning
Our negative-air machine seals onto the main trunk duct and puts the whole system under suction first. Then each run is scrubbed individually, so years of dust and debris travel one way only — out of the ducts and into the machine. The visit also covers the returns, where a winter of dry-air dust and pet hair mats together. That local standard is what air duct cleaning in Markham, IL means with Air Duct Service Co.

A duct system in Markham runs hard in both directions - deep-winter heating, humid-summer cooling - usually from a big trunk in the basement. This is what we actually find here, and what we check on every visit.
Midwest summers are humid even when they are not extreme, and moisture makes duct dust cake instead of staying loose. By late summer the buildup in a Markham system is packed, which is why a register wipe changes nothing - the load is in the trunk and the returns.
Finishing a basement in Markham usually means boxing ducts into soffits and ceilings where they cannot be seen or reached easily. Leaks and dust loads hide in there for years, and a camera inspection is the only honest way to know the condition of the runs serving half the house.
Split-levels and ranches across Illinois share a layout flaw: the primary bedroom sits at the very end of the longest run. By the time air travels a leaking trunk and thirty feet of branch, the room gets what is left - an airflow problem that belongs to the ducts, not the furnace.
Tree pollen in spring, grass in summer, ragweed into fall - Markham allergies barely get a break, and return ducts store every season's pollen and pass it along in winter. Cleaning the reservoir out is why many families book in early fall, before the house closes up.

Same-day service, free estimates, licensed & insured — and a air duct that lights when you click the remote.
Every few years for most Markham homes - sooner with pets, a finished-basement project, or allergy sufferers in a house that closes up tight all winter. We camera-inspect free and show you the inside of your own trunk, so you decide from evidence, not a sales pitch.
Yes. Finishing work loads the system with drywall dust, and the boxed-in runs are the hardest to assess afterward. In Markham we camera the trunk and the soffit runs, clean what the project left behind, and check the joints the remodel may have disturbed.
Long furnace or AC cycles, rooms that lag the thermostat, dust that returns within days of cleaning and weak flow at the far registers. Across Markham, failed tape on basement trunk joints is the most common finding, and mastic sealing is the permanent fix.
In growing parts of Markham, often yes: systems run during construction, and drywall dust packs into new ductwork before move-in. The inspection is free and the camera does not exaggerate - owners see the trunk's condition and decide for themselves.

No — and be wary of anyone who does. Every duct system is a different size and condition, so a phone price is a guess that changes at your door. Our inspections and estimates are free: a tech looks inside your actual ductwork first, then gives you one clear price before any work starts.
