Your ductwork plays a major role in how comfortable, efficient, and healthy your home feels. Even with a high-performing furnace or air conditioner, damaged, dirty, leaking, or poorly designed ducts can make your HVAC system work harder than it should.
At Lenz Heating & Cooling, we provide professional ductwork services for homeowners across the Des Moines metro, including duct inspection, repair, replacement, cleaning, sealing, and airflow improvements. Whether your home has uneven temperatures, weak airflow, dusty rooms, or rising energy bills, our team can help identify the source of the problem and recommend the right solution.
Your ducts are responsible for moving heated and cooled air throughout your home. When they are dirty, damaged, loose, undersized, or leaking, comfort problems can show up quickly.

Lenz Heating & Cooling helps Des Moines homeowners find practical solutions that improve airflow, system performance, and whole-home comfort.

If your home has uneven temperatures, weak airflow, excess dust, or rising energy bills, your ductwork may be part of the problem. Our technicians inspect accessible ducts, vents, returns, airflow patterns, and visible signs of damage or buildup to help determine whether the issue is with your HVAC equipment, duct system, or both. A ductwork inspection can uncover loose connections, leaks, crushed ducts, poor airflow distribution, debris buildup, or moisture concerns. From there, we can recommend the most practical next step.
Small duct issues can have a big impact on comfort. Loose sections, damaged ducts, and air leaks can waste conditioned air before it reaches your rooms. Ductwork repair can help improve airflow, reduce hot and cold spots, lower system strain, and restore comfort without replacing the entire duct system.
In some homes, repair is not enough. Older ductwork may be damaged, poorly sized, deteriorating, or no longer able to support your heating and cooling needs. Duct replacement may be recommended when leaks are widespread, airflow problems affect multiple rooms, or your existing duct layout is inefficient. Properly installed ductwork can improve comfort, energy efficiency, and long-term HVAC performance.
Leaky ductwork can make your HVAC system work harder while still leaving certain rooms uncomfortable. Duct sealing helps keep heated and cooled air moving where it belongs. By sealing leaks and improving airflow, Lenz Heating & Cooling can help reduce wasted energy, improve room-to-room comfort, and support more efficient system performance.
Over time, dust, debris, pet dander, and other particles can collect inside your ductwork. Professional air duct cleaning helps remove built-up debris so your HVAC system can circulate cleaner air through your home. Our experienced technicians use professional tools and high-powered vacuums to clean ductwork thoroughly. When appropriate, antimicrobial treatment may also be applied for added protection. Duct cleaning may be especially helpful after remodeling, moving into a new home, or noticing excess dust around vents.
Dryer vent cleaning helps protect both safety and efficiency. Lint buildup can restrict airflow, cause longer drying times, and increase the risk of overheating. You may need dryer vent cleaning if clothes take more than one cycle to dry, the dryer feels unusually hot, lint collects around the unit, or the laundry room feels warm and humid. Keeping the vent clear helps your dryer run more efficiently and supports a safer home.
Your HVAC system can only perform as well as the ductwork supporting it. If the duct system is leaking, dirty, blocked, or poorly designed, your furnace and AC have to work harder to move air through the home.
Investing in ductwork services can help improve:
Better airflow helps reduce hot and cold spots so more rooms feel consistent.
Sealed, clean, and properly sized ducts help reduce wasted energy.
Cleaner ducts and better filtration help reduce dust, debris, and airborne particles.
When airflow improves, your HVAC equipment does not have to work as hard.
Repairing loose or damaged ducts can reduce rattling, banging, and whistling sounds.

At Lenz Heating & Cooling, we believe HVAC service should be honest, clear, and stress-free. Our team helps homeowners across Urbandale, Des Moines, West Des Moines, Ankeny, Clive, Altoona, Waukee, and nearby communities improve comfort with practical ductwork solutions.
At Lenz Heating & Cooling, we help homeowners improve airflow, comfort, and indoor air quality with honest ductwork solutions. Whether your ducts need cleaning, sealing, repair, or replacement, our “To the Penny” Pricing Guarantee means you’ll know the cost upfront with no hidden fees or surprises.
Uneven temperatures, weak airflow, dusty rooms, or noisy ducts can all point to ductwork issues. Our experienced technicians inspect your system carefully, explain what we find, and recommend the right solution to help your HVAC system move air more efficiently throughout your home.
We believe ductwork service should be clear, honest, and pressure-free. If another company has recommended major duct replacement or costly repairs, our team can take a second look and help you understand whether cleaning, sealing, repair, or replacement makes the most sense for your home.
Signs include weak airflow, uneven temperatures, noisy ducts, rising energy bills, or visible duct damage. A professional inspection can confirm whether the issue is duct-related.
No. Duct cleaning removes dust, debris, and buildup from inside the duct system. Ductwork repair addresses physical problems like leaks, loose sections, damaged ducts, or airflow restrictions.
Yes. Leaky, dirty, or restricted ducts can force your HVAC system to run longer and work harder, which may increase energy use and reduce comfort.
Replacement may be recommended if ducts are severely damaged, poorly sized, deteriorated, or causing widespread airflow problems throughout the home.
It can help, especially if your ducts contain dust, debris, or airflow restrictions. For best results, ductwork service may be paired with proper filtration, duct cleaning, and indoor air quality solutions.
Homeowners throughout Central Iowa trust Lenz Heating & Cooling for clear communication, honest recommendations, and dependable service.

We called another company who quoted a high price for a replacement. I didn’t know so scheduled an appointment. My husband talked to Al Lenz who quoted a much better price so we moved to Lenz on Friday where they were able to come first thing Monday to replace. On time, super nice, very clean, efficient. Great company. Thank you Glen and Jeff for the good work you did. Our old water heater was leaking so much water they worked to get it out a different door to save my house from being a nippy mess. And also gave love to my dog. Brownie points … very caring nice people.
