J & J Heating Air & Refrigeration | Professional HVAC Repair in Lancaster, SC

Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your energy bills. If you notice any of these, it's time to call J & J for a professional diagnosis and repair to protect your system and efficiency.

In Lancaster's humid climate, we recommend a professional coil cleaning at least once a year, ideally during your spring AC tune-up. A dirty evaporator coil forces your system to work harder, reducing cooling power and increasing wear. Our maintenance service includes a thorough coil cleaning to ensure optimal performance and prevent breakdowns.

Most often, a qualified technician can locate and repair the leak, then properly recharge the system with refrigerant. Full replacement is typically only necessary if the leak is severe, the unit is very old, or other major components are failing. We'll provide a honest, upfront assessment and recommend the most cost-effective solution for your home.
