HVAC Repair Durham NC | Call J&J Hvac

Common signs include your AC running constantly without cooling properly, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing sound from the unit, and a sudden spike in your energy bills. In Durham's heat, a leak means your system works much harder. If you notice these issues, it's best to call for a professional diagnosis to prevent further damage and restore efficiency.

Durham's humidity can speed up corrosion. The best prevention is regular professional maintenance, where we clean the coils, check electrical connections, and ensure proper drainage. We also recommend keeping the unit clear of plants and debris, rinsing the fins gently with a hose a few times a season, and considering a protective cover during winter (but never while the unit is operating).

We strongly advise against this. Refrigerant isn't a consumable fuel; if your system is low, it has a leak that must be found and repaired by a licensed technician, like ours at J&J Hvac. Simply adding more refrigerant is illegal for environmental reasons, won't solve the underlying problem, and can lead to more costly repairs down the line. Let us diagnose the real issue safely and correctly.
