Merry Christmas from all of us at Heat Transfer Sales of the Carolinas!

Our offices will be closed on Monday and Tuesday, December 25 and 26, so that our employees may enjoy the holiday with their family and friends. However, we understand that critical needs still arise, even (and sometimes especially!) on the holidays. Our customer service team is ready to assist you throughout the holiday weekend if you experience a parts emergency for critical systems. Please contact us at 800-842-3328 and follow the after-hours instructions. We hope you have a safe and merry Christmas!

Why you should contact us

"As far as customer service goes or anything else for that matter; It does not get any better than Heat Transfer Sales! Angie, Tyson, and Elizabeth will bend over backwards to take of you. It has been a real pleasure to work with HTS."

We replaced our old equipment with the AERCO Modulex. We chose the Modulex because of the low energy consumption, the way the equipment modulates according to the demands of the system and the dependability. I have a lot on my plate and I enjoy having equipment that I don’t have to worry other than routine maintenance. Matt Rogers of HTS came and helped set up our units when they were installed. He is very knowledgeable and took the time to help me understand more about the Modulex and its maintenance requirements. HTS offers prompt service, good products and ease of mind. You just don’t have the worry about the products they sell or if they will maintain it.
