Worry-Free Duct Services™ in Knox County
Certified Duct Professionals Improving Your Air Quality
After traveling through your attic, crawlspace, and interior walls, ductwork can get pretty dirty, especially when it has cracks, gaps, or holes in it. Unsealed ducts suck in dirt, dust, and other allergens, which can significantly impact your indoor air quality. Luckily, Russell & Abbott Heating and Cooling has a solution. Our certified duct technicians provide second-to-none duct services in Knox County to keep your property healthy. We also proudly offer our services in Blount and Loudon counties.

Our Worry-Free Duct Sealing Process
Shockingly, 25-40% of conditioned air leaks from ductwork before it has a chance to make it into your home. Duct sealing can prevent energy loss, protect your HVAC equipment, and reduce energy bills. We have developed a comprehensive duct sealing process to ensure the best possible results. Using industry-leading tools and technology, the entire service is done in just one day!
Below is a breakdown of our Knox County Worry-Free Duct Sealing process:
- Inspection: Using in-duct cameras, our technicians conduct a thorough inspection of your ductwork to assess its overall condition and come up with a plan of action.
- Brush and vacuum: Using a state-of-the-art brush and vacuum system as well as our in-duct camera, we thoroughly clean the inside of your ductwork.
- Pressurizing preparation: Once we are ready to get to work, our team places either tape and foam or wooden blocks to prepare for pressurization.
- Isolation: We isolate the HVAC units to block them from the sealing process.
- System connection: We connect the sealing system to the ducts with clear plastic tubing.
- Pre-seal test: We conduct a pre-seal test by activating pressurization. This helps us to measure the exact amount of leakage in your ducts.
- Sealant application: Sealant is then applied to the inside of the ductwork by being blown through the clear plastic tubing. The entire process is monitored by our in-duct cameras.
- Completion: Once the sealing process is complete, you will receive a certificate of completion documenting our results.
