  • Reduced Allergens and Irritants: Over time, dust, pet dander, pollen, and other allergens can accumulate in your ductwork. Regular duct cleaning removes these particles, ensuring cleaner air and reducing the risk of allergies and respiratory irritation.
  • Improved Indoor Air Quality: Clean ducts contribute to better indoor air quality by preventing the circulation of dust and pollutants. This is especially crucial for individuals with respiratory conditions such as asthma or allergies, as well as for promoting overall health and well-being.
  • Enhanced System Efficiency: When your ducts are free of debris, your HVAC system can operate more efficiently. Clean ducts facilitate better airflow, allowing your system to distribute heated or cooled air more effectively. This efficiency not only improves comfort but also reduces energy consumption and lowers utility costs.
  • Prevention of Mold and Mildew Growth: Ductwork provides an ideal environment for mold and mildew growth if moisture is present. Regular duct cleaning helps eliminate any accumulated moisture and prevents the development of mold, ensuring a healthier living environment and avoiding potential respiratory issues associated with mold exposure.

Meet Us – Everest Air

Everest Air – Heating and Cooling was founded by Brad and Lynnsey Williams on January 29th, 2019. HVAC is in Brad’s blood. His grandfather opened an HVAC training school in 1994 when Brad was just 3 years old. His parents then opened a heating and air conditioning company when he was 10 years old. He went to work one summer when he was in high school, and that was it, he was an HVAC guy.

When he was 21, he moved to Panama City, FL and enjoyed the beach for a few years. Brad met the love of his life, Lynnsey, on April 7, 2015. In October of 2016 they were married and in July 2018 they discovered they were pregnant!
Wanting their daughter to have a close relationship with family, they decided to make the move from the beach to the mountains of Tennessee with their three dogs: Steele, Dexter and Bailey, and a baby in the oven!

Brad had tried his hand at a few different things from selling solar energy systems door-to-door to becoming a realtor and selling real estate. However, he eventually realized that he needed to stick with what he knew best and go back to his roots, HVAC.

With the intention of creating a life that would allow them to spend ample time with their daughter, they decided to build their own heating and air conditioning company and they named it after their beautiful daughter, Charlotte Everest Raine Williams.

Brad’s parents taught him that the best way to get and keep customers was to always honor your word and provide a quality service. Brad and Lynnsey believe that convenience is also a major part of providing a customer friendly experience and therefore, we have reliable regular business hours and offer easily scheduling so customers stay happy! They know that money is hard earned and offer customer friendly pricing as well.

In all, they are a small family with big dreams and strive to grow some deep roots here in East Tennessee.

We Love Our Customers!

Everest Air is a family-owned and operated air conditioning and heating company established in Maryville, TN in 2019. Having lower overhead allows us to offer better pricing than some of the other HVAC companies out there. Even if it means putting in space heaters or AC units while we fix your issue - Your comfort is our priority.

What equipment do you repair?

We repair most systems from leading manufacturers such as Trane, Goodman, York, etc. Our work is covered by a satisfaction guarantee so be sure to read our warranty page!

York is a great company that provides excellent machines that last longer than others on average. If properly maintained, your new York will last significantly longer than the average lifespan of a system. They also offer a fantastic warranty.

What if I don't know what's wrong?

Don't worry, we can have a HVAC technician come out and perform a detailed diagnostic and figure out exactly what the issue is.

What if my city isn't listed in your service areas?

Don't worry, we're continuing to grow as a brand and are looking to expand to more service areas soon. You're more than welcome to call us and see if you're within our radius.

How long does installing a system take?

It depends on what type of system you're having installed. It can range from a few hours to several hours depending on the complexity of your setup, and whether you're getting a ductless, split system, or package unit. Call us and we'll give you a more accurate time frame.
