When you get your maintenance check, be sure to ask the technician to review the wiring for your heating, ventilation and air conditioning system.

Wiring issues can hurt safety, the system’s operations and your monthly utility bill.

Wires may vibrate loose or fray or develop faulty ticks. A burning smell is one warning sign. Another is a sharp jump in the frequency of flipped circuit breakers.

To minimize these possibilities, an experienced technician will check all components for wear and tear and determine if the electrical connections are tight. Melted or pitted contacts indicate obvious trouble spots. So do discolor areas and loose connections.
