Northglenn's Leading Commercial Duct Cleaning Service

Bring the other invoice or describe what they did. We re-inspect, identify what was missed (commonly the returns, the blower, or the coil), and quote the re-clean honestly. Many of our re-clean calls come straight after a competitor's visit.

Yes. Pre-close inspection-response is time-pressured and we treat it that way — same-day or next-day scheduling, a written report on completion, and photo documentation so the buyer's agent can sign off. It's a regular workflow across Northglenn.

Ask whether they use HEPA negative-air and seal the non-active registers; whether they clean the returns, blower, and coil or only the registers; whether the quoted price changes on-site; and whether you get before/after photos and an itemized scope. Those four answers separate a real clean from a quick upsell.

Yes — cigarette and cigar nicotine residue is one of our most common post-purchase asks. Standard reset: a full duct cleaning plus indoor coil clean, sanitize, and a new HVAC filter, documented with photos so you can show the system was reset.

Yes. New-build ducts often still hold construction debris, sheetrock dust, and insulation fragments that combine over the years with pet dander and outdoor allergens into a real airflow problem. We pull these out regularly on move-in resets.

Yes, after the dusty work is done. Drywall sanding and demolition push fine debris into the duct runs; cleaning afterward keeps it from recirculating through the home. If you're also encapsulating a crawlspace, do that first, then clean.
