Jeff Grissom (Owner)

I am the Heat and Air doctor. I may not have been to medical school but whatever ails your heating and cooling system, I can fix. I have been in the heating and air business for 34 years. That experience has earned my company numerous awards, respect, and many satisfied customers.

As further testament to my knowledge and abilities, I even starred in the nationally syndicated television show, Remodeling and Decorating, produced by Cinetel Productions in the early 1990s.

I learned hard work and self reliance at home. My dad taught me to do quality work for a fair price, to treat people right and they will always come back. We work hard to please our customers. The foundation of my business has been built upon satisfied customers who have confidently referred Grissom Heat & Air to others. We have many people who have called on us for four or five systems in both residential and commercial environments. I am proud to say that I have worked with several children of past customers. That makes me feel like we are creating a legacy of good business practices. Our customers are our best referral systems.

After graduating from Knoxville's Halls High School in 1978, at the age of 17, I immediately started learning my future business. I had hoped to work with my father as a firefighter but had already been working in the heat and air business for four years by the time I was old enough to apply. I was installing systems by the time I was 19 and was in business for myself at the age of 22.

I earned an eighteen month degree at Knoxville State Vocational and Technical School in just 10 months. I also attended factory training sponsored by Goodman, Amana, Rheem, York, American Standard, and Honeywell.

As a life-long Knoxvillian, I know the importance of making and keeping good friends - in business and in life. As a father of five, I know the importance of home and family. When I service a family's heat and air system, install a new one in a family's future home, or work with a small business owner to reduce energy cost, I am working on a relationship that I want to continue. Grissom Heat & Air is ready and willing to start a relationship with you.

We expertly custom design each system to each site guaranteeing peak performance and comfort. We offer a vast array of products, makes, and models, enabling us to cater to any particular need.

The Grissom team installs heat and air systems in residential and light commercial buildings from the ground up. 

I ensure safety and comfort in all residential and commercial installations. I only use high-quality materials like copper wiring for consumer safety and sheet metal and flexible connections for long-lasting durability, thereby getting the best performance for the consumer.

Installing new systems or replacing old, inefficient units in older homes and buildings is another challenge I gladly accept. In either case, finding the right unit for each situation is paramount.   "I won't sell something I do not believe in."  My name is the one that's out there and on my  business. I won't jeopardize my good name.

One of my strengths as a business is my ability to communicate with my customers and determine their goals.  "My priority is finding out what is important to each and every customer and doing my best to meet his or her needs."

I am adamant about service after the sale. If a problem occurs when the summer sun is blazing or temperatures dip near freezing, it's important to know that help can be found nights or weekends in order to keep a family comfortable or a business operating. We work on all systems whether we originally installed the unit or not.
