AC leak repair across northeast Tennessee is a call away with ThermoSTAT Heating & Cooling. Our team finds refrigerant leaks fast, fixes them right, and gets your cooling back. Whether you have a small leak or a bigger problem, we give you an honest estimate before we start work.
Our technicians start by checking system pressure and using leak detection tools to find where refrigerant is escaping. Common leak spots include the evaporator coil, fitting connections, and the outdoor condenser. Once we locate the leak, we clean the area, make the repair, and recharge the system with the correct refrigerant type. If the leak is in a major component, we walk you through your options so you can decide what makes sense for your home and budget. Most repairs are done the same day. If your system just needs a top-off after the leak is sealed, our AC refrigerant recharge service handles that.
