"Outstanding experience."

We had a great experience working with Kim & Willis to choose and install our new fireplace. Not only were they exceptionally knowledgeable and incredibly helpful; they are very nice people as well. We never felt like they were putting the “sale” before what was right for us. We would certainly refer all our friends to IHT

“My husband and I inherited a hot tub when we bought our house and we had no clue what to do with it.”

We called IHT and were not disappointed. The customer service was great, everyone we worked with was super nice. On the day of our appointment, the technician, Bill, was excellent! He walked us through what we needed to do to maintain the hot tub and told us everything he was going to be doing. He left our hot tub looking sparkly and new. Highly recommend them!

They are available, knowledgeable and want to help. From our initial purchase in 2018 through any questions we have, to the most recent query on some warranty needs…. The team is the best. Thank you. It is appreciated. IHT is the go to place for your hot tub and needs.
