Certified HVAC Cleaning for Healthier Indoor Air

The air you breathe is only as clean as your duct system. Dust, pollen, debris, and even mold can build up inside your HVAC ducts, circulating contaminants through your home or business. Over time, this leads to poor air quality, allergy flare-ups, and strain on your ventilation system.

That’s why K-tech Kleening provides professional air vent cleaning for both homes and businesses. With NADCA-certified technicians, advanced equipment, and proven cleaning methods, we restore fresh, healthy air and protect the performance of your HVAC system.

Why Regular Duct Cleaning Matters

Dirty ducts not only affect your health but also make your system work harder. Without proper cleaning, you risk:

Poor Air Quality: Circulating dust, pollen, and microbial contaminants.
Respiratory Issues: Aggravating allergies and asthma.
System Damage: Forcing your HVAC to work harder, leading to breakdowns.
Higher Costs: Increased energy bills and expensive duct repairs or replacements.

Routine cleaning improves both your indoor environment and the efficiency of your system.

Residential Air Duct Cleaning

Your home should feel like a safe and healthy place, but dirty air ducts can compromise that. Dust, pollen, pet dander, and even mold spores often collect inside HVAC systems, circulating throughout bedrooms, living rooms, and basements. K-tech Kleening’s residential air duct cleaning removes these contaminants to restore clean air for you and your family. The result: easier breathing, reduced allergy triggers, and peace of mind knowing your system is working efficiently.

Commercial HVAC Cleaning

Clean air matters just as much in the workplace. For employees, tenants, and customers, dirty ducts can aggravate health issues, increase dust buildup, and even impact productivity. As a commercial duct cleaning company, K-tech Kleening provides large-scale duct cleaning for offices, healthcare facilities, industrial buildings, and more. Our NADCA-certified technicians use advanced equipment to ensure HVAC systems remain safe, efficient, and compliant with health standards.

Our Professional HVAC Duct Cleaning Process

Our NADCA-certified technicians use industry-leading tools to clean every component of your ductwork:

Inspection:

Video inspection to identify contaminants and buildup.

Protection:

Covering registers and furnishings to safeguard your space.

System Access:

Creating an access point and flushing ducts with air at 75 mph into a powerful vacuum.

Agitation & Removal:

Loosening debris with brushes and air-powered tools, then capturing everything in a large environmental vacuum.

Sanitizing:

Cleaning and sanitizing each air register.

Testing:

Ensuring the duct system is clean, safe, and efficient.

We also offer optional air duct sanitizing services for added protection against microbial contaminants.

Dryer Vent Cleaning: A Critical Safety Service

Clogged dryer vents are a hidden fire hazard. The U.S. Fire Administration reports 2,900 dryer fires each year, with 34% caused by clogged vents.

Our dryer vent cleaning process reduces this risk and improves dryer efficiency. Benefits include:

• Lower fire risk
• Faster drying times
• Longer dryer lifespan

We had K-Tech come to our home after our sump pump failed. Water consumed pretty much the entire carpeted finished basement. The K-Tech team was prompt, very knowledgeable, thorough and extremely professional. Highly recommend! Thank you K-Tech Team

We bought our house in 2020, and our vents were scary, but now they're SO clean! They even found a couple very old mouse skeletons under decades of dust!! We had one small issue where a vent upstairs wasn't covered and a bunch of dirt blew all over our bathroom, but other than that we were very happy with the work done on our vents. I know they weren't expecting that particular vent to be part of the line they were working on, but in a 120+ year old house, that can be hard to figure out.
I would just suggest asking that they cover every vent not being serviced at a given moment to avoid this issue yourself. The crew was polite and they were able to schedule us within a week of calling. Several of my friends were calling them the same day after seeing the before and after pictures. It was shocking!

Response from the owner 17:33 10 Mar 25

Thank you so much for sharing your experience! We're thrilled to hear that you're happy with the results and that your vents are now super clean. We appreciate your understanding about the unexpected vent issue and we'll take your suggestion to ensure vents are properly covered moving forward. It's always fascinating what can be found in older homes, and we're glad we could help improve your air quality. If you ever need anything in the future, don't hesitate to reach out. Thanks again for your trust, and we appreciate you recommending us to your friends! We will also send a $50 gift card for the inconvenience. Please call 715-355-1369 to arrange pick up. Your friends at K-tech.

I have a small living room. I removed and reset all the furniture myself.The guys came and were over an hour early. They did call ahead and asked if they could come earlier. They set-up quickly and were done in about 20 minutes. They removed a rust spot and many others. I still have a slight area that they couldn't get clean in the traffic area. But let me know ahead of time it would probably not get all of that. Only slight disappointment was I asked if they had a deodorizer and they stated it only last about 2 days. And was an extra charge. I have never been charged for this by other companies in the past???

Response from the owner 16:19 02 Dec 24

Thomas, we’re glad to hear that you were pleased with the prompt arrival, quick setup, and the removal of the rust spot and other stains. We always strive to be transparent with our customers, so we’re happy to hear our technicians communicated about the expected results on the traffic area beforehand.Regarding the deodorizer, we understand your concern about the additional charge. Our deodorizing service is an optional add-on because we use high-quality products designed to be effective but temporary, as the scent naturally dissipates over time. However, we truly value your feedback and will review our pricing and communication policies to ensure we meet customer expectations.We appreciate your business and hope you’ll give us another opportunity to serve you in the future. If there’s anything else we can do to enhance your experience, please don’t hesitate to reach out!
