The J-Mart Services team proudly has over 35 years of combined technical hands-on experience. Our small family-owned business has been cooling Texas as J-Mart Services since 2009. We love helping people to be healthy and comfortable in their homes. Our focus as we meet new customers is to create a relationship based on trust: a trust that we are honest and capable. We don't only want as much business as we can get but the reputation for doing good business. Business Owner Phone: (254) 493-4510.
