CUSTOMER: 👍 I've tried several geothermal supply companies in the past, but Illinois Geothermal Supply, INC is by far the best. Their products are top-notch and the customer service is excellent. They always go the extra mile to ensure customer satisfaction. I am a very happy customer and will continue to purchase from them in the future. 👍
