Air Duct Cleaning & Replacement
At Miller Attics, we believe the quality of the air inside your home is just as important as the insulation in your attic. That’s why we offer professional air duct cleaning and replacement services designed to improve your indoor air quality, protect your family’s health, and restore the efficiency of your HVAC system.
Most homeowners don’t realize how much dust, pollen, pet dander, and even mold can build up inside their ducts over time. Every time your heating or cooling system runs, it pushes those particles into the air you breathe. Our goal is simple: remove those contaminants, seal leaks, and replace damaged ducts so your home feels fresher and healthier.
Why Air Duct Cleaning Matters
Your air ducts are the lungs of your home. Over months and years, they collect dirt and debris that can’t be seen but can definitely be felt—especially for anyone in your family who suffers from allergies, asthma, or other respiratory issues.
When ducts are clogged, your HVAC system works harder, wasting energy and raising utility bills. By investing in regular air duct cleaning, you’re not just improving the air you breathe—you’re also extending the life of your system and lowering your energy costs.

When Air Duct Cleaning Isn’t Enough
Sometimes, Air Duct Cleaning alone isn’t enough to solve the deeper issues hiding in your HVAC system. Over time, ductwork can become old, damaged, or may have been poorly installed in the first place. When this happens, it often leads to leaking air, uneven temperatures throughout the house, and higher energy bills. You might notice certain rooms feeling stuffy while others are too cold, or your system working harder than it should just to keep up. That’s where our professional air duct replacement services step in.
We carefully inspect your ducts to identify cracks, gaps, or outdated materials that limit your system’s performance. If replacement is needed, we use high-quality materials and precise installation methods to restore full efficiency and comfort. By combining regular Air Duct Cleaning with timely replacement, you ensure your home’s air stays fresh, your system runs smoothly, and your family enjoys consistent, healthy comfort year-round.
The Benefits of Professional Duct Replacement
We carefully inspect every part of your ductwork to identify cracks, gaps, leaks, or outdated materials that may be reducing your system’s performance. Even small issues in the ducts can cause significant air loss, forcing your HVAC system to work harder than necessary. During our inspection, we explain exactly what we find so you can make informed decisions with confidence. If replacement is needed, our team installs new, properly sealed ducts that restore efficiency, balance airflow, and improve overall comfort in your home.
Replacing old ducts isn’t just about fixing an immediate problem — it’s about long-term savings and healthier living. Studies show that upgrading ductwork can reduce energy waste by up to 30%, lowering utility bills and reducing wear on your system. When paired with regular Air Duct Cleaning, new duct installation helps maintain clean, healthy air while making your home one of the most efficient and comfortable on the block.
Air Duct Sealing: The Hidden Energy Saver
Even if your ducts are in good condition, leaks at the joints can cause significant air loss. We provide air duct sealing that closes these gaps, preventing cooled or heated air from escaping into your attic or crawl space. This means more consistent temperatures, less strain on your HVAC system, and lower monthly bills.

Dryer Vent Cleaning & Replacement – Common Questions & Answers
How often should I clean my dryer vent?
Most experts recommend at least once a year. If you use your dryer heavily (large family, pets, long vent runs), you may need cleaning every 6 months. A good rule of thumb: if drying time increases, it’s time to clean.
Should I clean the vent myself or hire a professional?
DIY is possible with the right tools (brush kits, vacuum attachments), but professionals have stronger equipment and can reach long or complex ducts. If your vent runs through walls, floors, or the roof, hiring a pro is usually safer and more effective.
What tools or kits work best for cleaning?
Popular options include:
Rotary brush kits that attach to a drill
Long flexible rods
Shop vacs with special dryer vent attachments
Many homeowners use a brush/vacuum combo. For long or tricky vents, professional-grade tools work better.
How much does dryer vent cleaning cost?
Prices vary by region and vent location:
Basic cleaning: $80–$150
Multi-story homes or roof vents: $150–$250
Some companies offer flat rates, while others charge extra for longer ducts.
Why is my dryer still not drying after I cleaned the vent?
Common causes:
Lint compacted inside the duct during cleaning attempt
Holes or crushed sections in the duct
Blocked vent cap outside
Damaged blower in the dryer itself
In these cases, you may need to re-clean, repair, or replace the duct.
When should I replace the dryer vent duct instead of just cleaning it?
Replace if:
It’s not rigid metal duct (old vinyl or plastic ducts are unsafe)
The duct is damaged, crushed, or has holes
There’s heavy lint buildup that can’t be cleared properly
Always use UL-listed rigid or semi-rigid metal ducts – never PVC or foil.
