What our customers say

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. Thank you, Karla P’Simer Dwight Amos Deane Hill Dental Laboratory, LLC

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!

Rob C. was super informative and super helpful when my AC unit wasn’t cooling my house. He helped recommend a couple of fixes - one was an immediate solution and one was a long term solution (more freon and new copper pipes) to keep my unit working longer/better (cleaning ducts). Hope I see him again if my HVAC unit messes up - (but I hope it doesn’t mess up any time soon, lol). 10/10 recommend. 😃

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.

I appreciate Jacob Newman coming out and evaluating damage to supply ductwork caused by raccoon(s) in our attic earlier this month. He explained what he saw and offered a few solutions. Jacob also helped fitting the project into our budget and schedule.

Patrick McGraw came out to check our duct work and central unit. He did the inspection and explained everything that he was doing. He did an awesome job! Will be using HEP again!

Jeremy S.

I spoke with Jacob Newman about cleaning my vents & he was extremely professional and provided different options of service. Highly recommend!

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

Comprehensive Duct Cleaning for Knoxville Homes and Businesses

HEP offers specialized heating and air conditioning duct cleaning in Knoxville designed to restore system efficiency and elevate indoor air quality. By targeting dust, pollen, pet dander, and other contaminants deep inside HVAC ductwork, HEP technicians help local property owners breathe easier and prolong the life of their equipment.

Key Objectives of HEP’s Service

Remove accumulated debris that restricts airflow
Reduce airborne irritants that aggravate allergies and asthma
Support balanced heating and cooling performance across every room
Extend the lifespan of HVAC components by minimizing strain

Why Regular HVAC Duct Cleaning Matters

Knoxville’s fluctuating weather and seasonal allergens can quickly find their way into ductwork. Without periodic cleaning, circulating pollutants may contribute to poor indoor air quality, higher energy bills, and frequent system breakdowns.

Advantages of Consistent Maintenance

Enhanced indoor comfort during both humid summers and chilly winters
Lower utility costs due to improved airflow efficiency
Reduced likelihood of mildew growth and musty odors
Greater peace of mind knowing the HVAC system is operating at peak performance

Signs Your Knoxville Property Needs Professional Duct Cleaning

Recognizing early indicators helps prevent bigger HVAC issues later. HEP recommends scheduling a cleaning when any of the following arise:

Visible dust bursts from supply vents when the system starts
Stale or musty odors that linger in multiple rooms
Uneven temperature distribution between floors
Increased allergy or respiratory symptoms indoors
Notable rise in utility bills without a change in thermostat settings
Recent renovation or construction that introduced extra debris

The HEP Duct Cleaning Process

HEP’s approach combines advanced equipment with industry-recognized best practices for a thorough, mess-free service.

Initial System Assessment

Technicians evaluate the entire HVAC layout, including supply and return ducts, air handler, and registers. Any areas of concern are documented before cleaning begins.

High-Efficiency Vacuum Extraction

A powerful, truck-mounted vacuum creates negative pressure inside the duct system, pulling loosened contaminants out through sealed hoses rather than dispersing them into living spaces.

Rotary Brush & Compressed Air Agitation

Specialized rotary brushes scrub interior duct surfaces while compressed air whips dislodge stuck-on debris, ensuring even deeply embedded particles are captured.

Sanitizing & Deodorizing Treatments

Upon request, EPA-approved solutions are applied to neutralize microbes, odors, and mold spores, leaving a fresh, clean scent without harsh chemical residue.

Post-Cleaning Verification

Technicians perform a final inspection, confirm airflow improvements, and ensure all registers and grilles are reattached securely before departing.

Benefits of Choosing HEP for Heating and Air Conditioning Duct Cleaning

Local experience and technical expertise set HEP apart in the Knoxville market.

NADCA-aligned methods for quality and safety
Certified HVAC professionals familiar with regional climate challenges
Attention to detail that protects furniture, flooring, and personal belongings

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.
