How much does an air duct cleaning in Denver cost?
In Denver, a professional air duct cleaning service for an average-sized home typically ranges from $350 to $700.

1. Action Air Duct Cleaning Denver
Address: 100 Fillmore St Suite 563
Phone: +17202573319
Business Hours:
- Monday to Saturday – 7 AM to 9 PM
- Sunday – 8 AM to 7 PM
Action Air Duct Cleaning Denver left a solid impression right our first call. The team was responsive, clear about pricing, and eager to answer even the smallest questions.
They arrived on time, inspected the ducts thoroughly, and explained every step of the cleaning process before starting. The technicians used professional-grade vacuums and brushes to remove years of dust buildup—something we didn’t even realize was that bad until we saw the before-and-after photos.
The only downside was the cost—it’s definitely on the higher end compared to some competitors.
That said, after seeing the quality of their work and attention to detail, we could understand why. They spent extra time sealing leaks and cleaning vents that previous services had missed entirely.
By the end of their visit, the air quality in our home noticeably improved, and even the faint musty odor was gone. It’s clear these pros know what they’re doing and genuinely care about the results.
Used clean and powerful cleaning equipment
“We had a great experience with Tamir and his company. A 2-person crew, headed by Elizabeth, came after hours because we were leaving our condo for 6-weeks. The equipment was clean and powerful. They were efficient and scrupulously clean. They cleaned and sanitized 2 heat pump systems with 10 registers and ducts in 2 hours. The air felt and smelled better, immediately. We highly recommend these folks.”

A very responsive, professional, and skilled team
“I needed a vent hood installation to replace an old over the range microwave that did not vent. Cooking fumes just sat in the house. I didn’t know where to start and am so glad I found Action Air Duct. Tamir was very responsive at every stage, professional, and skilled. He walked me through every step and provided a great recommendation for the range hood product. When it arrived, he completed the install with a new exterior duct creation quickly. What a huge life upgrade! The kitchen feels more spacious, and vents properly to an exterior duct. Highly recommend Action Air Duct for this service.”

2. Zerorez Carpet and Air Duct Cleaning of Denver
Address: 2635 S Santa Fe Dr # 3A
Phone: +13034715150
Business Hours:
- Monday to Saturday – 7 AM to 6 PM
Calling Zerorez felt like chatting with a company that really knows its stuff. From the start, their rep explained how their Zr Clean technology works—using water that’s been electrolyzed to lift dirt and grime without the use of harsh chemicals.
It’s a big plus if you have pets, allergies, or little ones at home. The process sounded both high-tech and practical, and the technician we spoke with walked us through what a typical cleaning day looks like, from setup to post-cleaning checks.
They offer more than just air duct cleaning, too—carpets, tiles, upholstery, and dryer vents are all part of their lineup. Several clients we researched mentioned how punctual and careful their staff are, even wearing protective booties indoors and explaining every step.
However, one consistent observation stood out—the team can be a bit pushy with upselling additional services.
Friendly and thorough technicians
“I booked Zerorez for two days in a row for some post-construction cleaning: air ducts and carpets. Both technicians were very friendly and thorough. Each one called with plenty of notice when they were on their way. Both of them were very communicative throughout the cleanings and explained what they were doing and why. The quotes I received in advance when booking over the phone were the exact amount charged at the end of each appointment. Great experience! I would have reserved them for wood floor cleaning as well, but the Denver location does not offer hardwood cleaning. Highly recommend!”

Tech was very cautious
“We went with a discount air duct cleaning in our old house but decided to go with a more legit service as our current house is bigger and built in the 70s so we were afraid there might be decades of build up in the ducts. It was well worth the extra amount spent. It was a very thorough job and the tech was cautious inside our home. I never once saw him without booties, unnecessary but very nice. He had to come into my office and patiently waited a few min for me to finish an unexpected call to avoid noise. It was easy to schedule and I was able to get a coupon off the website. I will be recommending this to anyone who needs air duct cleaning. We added on our dryer vent too and so far no more error codes about the lint trap 🤞”

3. LEV Air Duct Cleaning INC
Address: 909 Bannock St #1634
Phone: +17209278730
Business Hours:
- Monday to Sunday – 8 AM to 8 PM
LEV was one of the most responsive companies we reached out to in Denver. Their rep took the time to walk us through their services: air duct cleaning, dryer vent cleaning, and attic insulation, and broke down the cost clearly.
They also explained how their cleaning process removes allergens and buildup that can affect air quality, which is especially useful if you or someone in your home deals with allergies.
When we asked about scheduling, they offered flexible time slots and even same-day availability, which shows how well they manage their workload.
However, one thing we noticed during our call was their tendency to upsell additional services even after we had declined. It wasn’t aggressive, but felt slightly persistent.
That aside, LEV’s reputation holds strong. Customers consistently praise their technicians for being detail-oriented, professional, and transparent about what they’re doing.
Spectacular technicians
“Dan and Lian came to my house to clean my air ducts. They were spectacular. Vents look incredible. Both of them were very professional, friendly, and accommodating. They walk through every step of the process with you so there are no surprises. Highly recommend there services.”

Very professional and fantastic team
“Dan and Lian were fantastic and very professional. Up front Dan explained all of our options for their services. We went with the Ultimate package. They did a great job cleaning our ducts and the dryer vent. We’re very happy! Thank you for everything! We’ll be in touch the the coming years for your services again.”

4. Lowe’s Air Duct Cleaning
Address: 2150 S Bellaire St Ste E
Phone: +13037315206
Business Hours:
- Monday to Tuesday, Friday – 6 AM to 4 PM
- Wednesday to Thursday – 6 AM to 6 PM
- Saturday – 7 AM to 5 PM
Lowe’s Air Duct Cleaning has been serving Denver and nearby areas for over a decade, and it’s easy to see why they’ve built such a strong reputation. When we reached out to them, the staff was quick to respond and gave a full breakdown of their process, from using camera inspections to following strict NADCA standards.
They also offer flat-rate pricing with no hidden fees—a big relief when comparing them to other companies that like to tack on surprise charges later. We also noted their transparency, as several clients mentioned how the technicians explained every step and even showed before-and-after photos.
Their team’s honesty, like advising homeowners when a service wasn’t necessary, reflects genuine professionalism.
The only catch? Their services are on the pricey side.
Awesome and top-notch technician they sent
“Luis is a top notch technician. He walked me through the house and showed me exactly what he was doing in each section. I got the extra service for cleaning the motor and evaporator coil. They were running a special so the pricing was very reasonable. When finished he let me know anything that I may need to address. I’d definitely use them again and I would request Luis Chavez.”
Joanna Medin, Google Review
Showed up early and completed an amazing work
“Luis came in and rocked it. Showed up early and got to work. When he was cleaning out my fan, he had issues getting to it, so instead of doing a half job, decided to pull it out to clean it properly. He did notice the fan wasn’t blowing to full capacity during his inspection, so he suggested I get someone to check it out. It’s hard to find good honest folks that days and he really shined.”

5. Apex Clean Air AC & Heating Repair
Address: 6401 Broadway Unit L
Phone: +17207305856
Business Hours:
- Monday to Friday – 7 AM to 6 PM
- Saturday – 9 AM to 4 PM
When we first reached out to Apex, one thing that stood out was their $49 air duct cleaning promotion. It sounded like a great deal at first, but after a few questions, we realized it only covers basic round vents.
Any rectangular ducts would add $100 to $200 each. That makes it a bit misleading if you’re expecting full-house coverage, especially for average-sized homes.
That said, their professionalism and technical expertise were hard to ignore. The representative patiently explained how their process improves both energy efficiency and indoor air quality.
They use advanced tools and HEPA-filtered vacuums to get deep into the system, and their technicians are trained to handle residential and commercial HVAC systems.
Customers we interviewed praised how Apex staff show up on time, wear protective gear indoors, and go above and beyond to solve issues quickly.
Very impressive team
“I’ve had a great experience with Apex Clean Air! From my initial consultation with Frank, then Ryan in Sales, then Michael & Alexis with the install team, and finally Donovan who cleaned our air ducts after our new system was installed. I was incredibly impressed with Donovan – he was super professional, a wealth of knowledge, and very pleasant to work with! He took the time to explain everything to me and also offered helpful tips to ensure my system was operating as best as it can. I didnt feel like he was doing a sales pitch, more like a friend who genuinely cares about keeping your home & family healthy & safe. I would definitely recommend Apex Clean Airs services.”
Jacey Soper, Google Review
Kind technicians and paid close attention to detail
“This is the second or third time we have had Apex Clean Air come out to help service our HVAC system. Their prices are incredibly reasonable and well worth it. Today Joe and Juan spent several hours cleaning out all the dust and debris. They were so kind and paid close attention to detail. I am very happy with the results and will continue to use Apex Clean Air!”
