Signs You Need Duct Repair
Uneven Airflow Room to Room
Some rooms cool or heat fine while others barely receive airflow, often a sign of a leak or disconnection.
Energy Bills Climbing
Conditioned air escaping through gaps means your system runs longer to hit the same temperature.
Visible Gaps or Disconnected Sections
Ductwork in an attic or crawlspace that’s come apart at a joint is losing air directly to unconditioned space.
Dust or Debris Blowing From Vents
A damaged duct can pull in insulation, dust, or attic debris and blow it straight into your living space.
Whistling or Rattling Noises
ir forcing through a small gap or loose connection often makes noise that gets louder as the leak grows.
Pest Entry Points in Ductwork
Gaps large enough for air to escape are often large enough for rodents or insects to get in as well.

What Our Customers Say
Aaron was amazing. I learned a lot about my AC he also helped me put the air duct on my dryer. Very professional great customer service.
I had a great experience with Honeycomb Heating and Cooling. My duct system was a complete mess—basically a Frankenstein setup—and they completely fixed it with brand new ductwork.
They got everything done in just 2 days, which was impressive on its own, but what really stood out was how thoughtful they were throughout the process. They even provided a portable AC unit overnight after day one so we stayed comfortable.
They walked me through multiple solution options, explained everything clearly, and helped me choose something that fit my budget without any pressure. Once we decided, they executed perfectly.
The whole team was professional, efficient, and easy to work with. Highly recommend them if you need HVAC or duct work done right.
Did a fantastic job with my new air duct for kitchen remodel! Very knowledgeable and explained all options. Cleaned up the site when done. Dorian and Manuel did great!!

Frequently Asked Questions for Duct Repair & Sealing
What’s the difference between duct sealing and duct repair?
Sealing closes small leaks at joints and seams using mastic or an interior sealing process. Repair covers physical damage, like a crushed, disconnected, or torn section of ductwork.
How do I know if my ducts are leaking?
Uneven airflow between rooms, rising energy bills without a usage change, and visible gaps in accessible ductwork are the most common signs. A pressure test confirms exactly where and how much.
Will duct repair lower my energy bill?
Sealing leaks stops conditioned air from escaping into an attic or crawlspace, which means your system runs less to hit the same temperature. The exact savings depend on how much air was leaking before the repair.
How much does duct repair or sealing cost?
Duct repair and sealing runs $400 to $6,500 depending on scope. A pressure test identifies the actual damage first, and you get a price for that scope before work starts.
