The Duct Cleaning Services Approach
Duct Cleaning Services isn't a commodity service — and we don't treat it like one. Your ductwork is the circulatory system of your HVAC — and if it's leaking, restricted, or dirty, no equipment upgrade will fix your comfort problems. Our Duct Cleaning Services process starts with a static pressure test to measure airflow resistance. We then inspect accessible duct runs with a camera, checking for disconnected joints, crushed flex duct, and biological growth. Cleaning uses negative-pressure HEPA vacuums and agitation brushes — not the $99 scam companies that blow air and call it done. After service, we re-test to verify measurable improvement.
Why Longmont Residents Choose Us for Duct Cleaning Services
We measure before and after — you'll see quantifiable improvement, not just a promise.
Our negative-pressure vacuums capture particles down to 0.3 microns. No recirculation of dust into your home.
We show you what's inside your ducts before and after cleaning — photos included in your report.
After cleaning, we check all accessible joints for leaks and seal any gaps we find.
Drop cloths, shoe covers, and a complete cleanup before we leave. We treat your property like our own.
If anything we did on your Duct Cleaning Services job isn't right, we come back and fix it — no charge, no argument.

Homes in Longmont — many from the 1970s-2000s suburban growth — share common characteristics that affect repair and maintenance needs. The semi-arid continental climate creates hailstorms, which accelerates wear on specific systems. Our technicians know these patterns from years of hands-on experience in Longmont-area properties.

Duct Cleaning Services — Frequently Asked Questions
- Does duct cleaning improve efficiency?
- Yes — restricted ducts force your HVAC system to work harder, increasing energy consumption. We measure static pressure before and after to quantify the improvement.
- Can duct leaks be sealed?
- Yes. We use mastic sealant and foil-backed tape on accessible joints. For inaccessible duct runs, aerosol-based duct sealing (Aeroseal) can seal leaks from the inside.
- How do I know if my ducts need cleaning?
- Signs include visible dust blowing from registers, musty odor when the system runs, uneven room temperatures, or it's been more than 5-7 years since last cleaning. A static pressure test reveals hidden problems.
- How long does duct cleaning take in Longmont?
- A typical home takes 3-5 hours for a thorough cleaning with HEPA-filtered negative-pressure equipment. Companies that promise one hour are not doing it properly.
- Are your technicians employees or subcontractors?
- Every technician on our Duct Cleaning Services jobs is a direct employee — trained in-house, background-checked, and accountable to our quality standards.
- Do you provide written estimates?
- Yes — every Duct Cleaning Services estimate is written, itemized, and provided before any work begins. No verbal quotes, no surprise add-ons.
- Can you explain your Duct Cleaning Services warranty?
- Every Duct Cleaning Services job includes our written workmanship warranty. If something we did fails within the warranty period, we return and fix it at no charge. We put this in writing before the job starts.
