“Jeff has done my work for many years now. I’ve built homes from $200,000 to over one million and, regardless of the size of the project, he has always exceeded my expectations. I would highly recommend Grissom Heat and Air for all of your heating and cooling needs.”

-Robert Phillips, Robert Phillips Construction

“Recently, the air conditioning at my place of work went of the fritz. My manager opened the phone book and called one of the HVAC companies with a big ad. They came out, inspected the broken unit and quoted an outrageous price for repair work. I recommended a second opinion from Jeff Grissom because I personally used Grissom Heat and Air for repair work at my own home. Jeff came out and upon inspection the system, determined the unit only needed a good cleaning and a few minor repairs. We saved thousands of dollars! Jeff Grissom is an honest man who provides exemplary, efficient service for a fair price. I recommend Grissom Heat and Air to everyone. You won’t be disappointed.”

-Brandon Dishner, Smoky Mountain Ironhorse

“I’ve know Jeff Grissom for a long, long time. And one important thing with Grissom is the service after the sale. We build custom homes and certainly price and proper installation are important, but equally important is the service after the sale. They also have a 24-hour answering service and we’ve had no problems getting call backs during the night or on the weekends.”

-Tim Neal, Fairfax Development

“I’ve worked with Jeff Grissom of Grissom Heat and Air for many years. I continue to use them because their service is so great. They do a thorough job and if any situations arise they are always prompt to respond to them. They’re good people and they take care of their customers.”

-Keith Walker, Walker Construction

“Anybody can sell a good product, but I buy service, and that’s what Grissom Heat and Air provides. They always make themselves available.”

-Steve Price, Prestige Development Company

“I have worked with Jeff for over 25 years. We build custom as well as spec home in which price, proper installation and service are of the utmost importance. Jeff understands this and always delivers.”

-Larry Koontz, Larry Koontz Construction
