FAQs

Why is duct cleaning important for my HVAC system?

Over time, dust, debris, and allergens accumulate in your ductwork, affecting the performance of your heating and air conditioning system. Regular duct cleaning can help remove contaminants that circulate through the air and settle into your home’s vents. By removing this buildup, you can improve indoor air quality, support healthier breathing, and maintain efficient airflow throughout your HVAC system.

How often should I get my ducts cleaned in Knoxville?

Most HVAC experts recommend scheduling a professional duct cleaning at least once every 3–5 years. However, several factors affect the ideal cleaning schedule, such as whether you own pets, if anyone in the household has allergies or respiratory conditions, or if you notice a musty odor coming from the vents. Knoxville’s seasonal humidity and pollen levels may also accelerate the accumulation of debris, making regular inspections and cleanings even more important.

Are there health benefits to having my ducts cleaned?

Yes. While duct cleaning is not a standalone solution to all indoor air quality issues, it does help reduce the circulation of dust, pollen, pet dander, and other airborne contaminants. This is especially beneficial for individuals with allergies or respiratory conditions. Clean ducts can also help cut down on mold spores, which thrive in moist environments and can negatively impact your health if left unchecked.

What does the duct cleaning process involve?

A professional duct cleaning typically begins with an inspection of your HVAC system and ductwork to identify areas of heavy buildup and potential issues. Then, technicians use specialized equipment—like high-powered vacuums and rotary brushes—to dislodge and remove debris. They may also seal and protect your vents during cleaning to prevent contamination of your indoor air. Some services include sanitizing or deodorizing treatments to help eliminate odors and kill bacteria or mold.

Will duct cleaning improve my HVAC’s efficiency?

Yes. When ducts are clogged with dust and debris, the airflow can be restricted, forcing your HVAC system to work harder to maintain the desired temperature. By removing the buildup, your system can run more efficiently, which can lead to lower energy bills, reduced wear and tear on components, and a longer lifespan for your heating and cooling equipment.

How do I know if my ducts need to be cleaned?

Look out for signs such as visible dust or debris around the vents, musty or stale odors when the HVAC system is running, or inconsistent airflow throughout your home. An unusual increase in allergy symptoms among household members can also indicate excessive pollutants in the air. Scheduling a professional inspection is a reliable way to determine if duct cleaning is necessary for your home in Knoxville.

What our customers say

I cannot say enough good things about the HVAC crew at HEP. Glenn, Travis, Chino, Trevor, Jeff, and Damien worked late into the night to get our new heat pump installed and our old duct work replaced. They went above and beyond what I thought a company would do to get our heat working and prevent us from experiencing a very cold morning. A big THANK YOU to all of these guys!

All the people we have dealt with with HEP have been a pleasure. Very pleasant and informative also. Josh that came out and diagnosed the problem and Glen and the crew that did the instillation were are very nice and professional. Most recently we dealt with Glen, who came out to do the inspection on the unit to make sure it was working as it should, and it was another pleasant and professional experience.

They did an excellent job very professional. They were also helpful in retrieving a highly emotional valued piece of Jewelry for me that had fell into one of the vents. I would gladly and highly recommend Hep to anyone who has a need of work.

Update: In just a couple of days after agreeing to the install, the crew came out and installed both upstairs and downstairs units along with redoing some duct work, all within 1 day! Very neat install was completed! There were a couple of open items that were missed, but they have now finished those up and it looks great. Quoted new heat/air system. Very professional and knowledgeable. Will be using Hep to install in the near future!

Michael K.

Very professional and thorough. Complete gentleman with so much respect for me and my home. I truly feel like he got me the best deal possible in my very bad duct work situation. I hope if I ever need hvac work done again, it’s this gentleman who shows up.

John was great from start to finish. He quoted me the duct work I needed and even completed my maintenance check when it wasn't listed on the job quote

Kevin G.

After accepting the estimate for ducting three bathroom fan exhausts together and venting through the roof of my home, HEP sent two employees out within a day. Christian and Jacob were both very professional and efficient. The work was completed within four hours, and was exactly what was requested.

John was here 1/24/25 to check for replacement of my duct work. He was polite and told me the cost and even financing program. He helped me understand everything they would do. I think he deserves a recognition. And praise

Zack and Caleb were fantastic! They came on a Tuesday morning removed all old duct work and vent boots. Then proceeded to replace the vent boots and duct work that afternoon. They were very thorough, polite and clean. They returned on Wednesday morning to install another vent with duct work in our bedroom as there was only one when the house was built and it really should have had two. The job was completed with the installation of 10 new vent covers, a new return vent cover and a UV Blue Light HVAC sanitizer and air purifier to help with my asthma. Both Zack & Caleb knew their job and gave 110%. They certainly did not disappoint! Their supervisor Jeremy Hidden was here both days to make sure the job was being done to his and HEP standards. Jeremy also made sure they had all necessary supplies needed to complete the work! On Thursday because of a question we had, Jeremy came by and proofed/adjusted the airflow at the unit and made sure it was evenly distributed through the whole house with both heat and a/c. He is excellent to work with and is the ultimate example of what customer service is all about! We couldn't be happier and more comfortable since the work was done! We just wish ALL departments were run as efficiently and professionally as Jeremy's! Thank you - John and Barbara
