I highly recommend ductworks! Cesar did an excellent job cleaning all the air ducts, vents, and dryer vent throughout my house. He was extremely friendly, professional, and paid great attention to detail. What impressed me most was how thorough he was. He took the time to show me before-and-after pictures, and the difference was incredible! He also explained everything he was doing, including the technical details, in simple terms that were easy to understand. It’s refreshing to work with someone who genuinely cares about doing the job right and making sure the customer understands the work being done. Great experience from start to finish. I would absolutely recommend Cesar and Ductworks llc to anyone looking for quality duct cleaning services!

Mason showed up on time, made me feel at ease and answered all my questions. He used drop cloths and booties to keep my house clean. I enjoyed when he showed me before and after photos with random items found inside the vent ducts, like crayons, dog food and hair, and a random assortment of nails and building material debris. He did a good job cleaning around the vents when he was done, and didn't leave a mess behind for me to clean up. Kudos!

I recently purchased and moved into a 20-year old home. Shortly after having my wood floors refinished, our furnace blower motor failed and our furnace filter kept clogging with CLUMPS of pet fur and dust. The HVAC technician recommended duct cleaning. I've always been skeptical of duct cleaning, but I've also never seen the type of fur and dust build up in an air filter that I found in this new house. After spending far too much money on HVAC repairs, I decided to hire a duct cleaning company hoping to avoid recurring problems with my HVAC system. The technicians were courteous and professional. They explained clearly what they were doing and carefully moved (and replaced) furniture to access the ducts and returns for cleaning. Along the way they gladly shared photos of the ducts before and after their cleaning. The ultimate proof of the efficacy of the cleaning will be in a couple months, when I can see if the new air filter looks less like a wet dog and more like a normal air filter. I attached a photo of a brand new MERV 5 filter after 30 days in my system before I had ductworks clean my system. I've never seen an air filter this dirty and hope never to see one like this again.

Updated review: I originally left a lower review with Ductworks after a handful of my air registers suffered some minor cosmetic damage following a residential service. However, the moment Ductworks was made aware of the issue, they did everything in their power to get in touch with me and make things right. First they stopped by my house to assess the damage and see if repair was at all a possibility. They were quick to offer an identical replacement at no cost to me, and ensured all the other registers were up to satisfaction. They were always kind and took full responsibility. At the end of the day, mistakes can happen with these types of jobs. What spoke volumes to me was the way Ductworks handled themselves. They genuinely worked to ensure I was happy with the service when all was said and done.

Warren was very professional, respectful of our home, a focused and steady worker. I wish all the contractors/service providers coming into our home had the same approach tot heir work. The cleaning of our ducts was done so thoroughly. Im ashamed we hadn't had them done before now. I would most definitely recommend this company. Ducts are easy to forget but they play a very important role in how clean our home air is. Our home feels like new again. Thank you Warren!!!

Colorado Commercial & Residential Air Duct Cleaning Services

Air duct cleaning in Colorado is one of the smartest HVAC maintenance decisions for property owners. Over time, duct systems accumulate dust, allergens, and foreign contaminants that circulate through occupied spaces. As buildup increases inside the ventilation system, indoor air quality declines and HVAC efficiency drops, forcing heating and cooling equipment to work harder to maintain comfort. Ductworks, Inc., NADCA-certified and locally owned for 35+ years, provides professional Colorado air duct cleaning for commercial buildings and homes using proven source-removal methods that help restore airflow, improve system performance, and support healthier indoor environments.

Regular HVAC and air duct maintenance is essential for peak efficiency, safety, and long-term equipment performance. In many Colorado homes and commercial buildings, heating and cooling account for up to 50% of total energy use, making proper ventilation system maintenance especially important. Ductworks’ Complete Ventilation Cleaning Package™ and CleanCycle Program™ help ventilation systems operate more efficiently while reducing accumulated debris within the air conveyance system. These programs support improved system performance, extend equipment life, and help maintain consistent indoor air quality.

Air Duct Cleaning FAQs

Colorado’s dry climate causes ducts to collect debris quickly. This impacts indoor air quality and HVAC performance. Most homes benefit from cleaning every 3–5 years. However, you may need it sooner if you have pets, remodeling dust, wildfire smoke exposure, or asthma concerns.

Excessive dust is a common sign of a dirty system. For example, you might see heavy dust layers on your air filter. You may also notice dust on registers shortly after cleaning. Also, ask your technician to check the furnace cabinet during maintenance. Excessive buildup there means contaminants are likely circulating in your ducts.

NADCA certification proves a company passed rigorous testing. This covers HVAC mechanics, safety standards, and indoor air quality protocols. It is a clear signal of training and accountability. When you choose a NADCA-certified provider, you get trained professionals. They follow best practices for safety and healthier indoor air.

Yes. In fact, it is often the best time to improve air quality because you are continually re-circulating indoor air. In winter, furnace use creates drier air. This causes more dust to remain suspended in the living space. Ductworks, Inc. COMPLETE VENTILATION CLEANING PACKAGE™ uses a Portable, HEPA-filtered, Closed-loop process. Our equipment operates inside without outdoor hoses. Your doors stay shut and your home stays warm while we work.
