my dogs have chewed my central air contactor wire.my ac will not cut on. does anyone knows how to replace them and where to buy replacement wires locally( i live in Dallas TX.) i would like to do it myself instead of spending a lot of money.
You shouldn't need to replace the wires, only splice them back together, color to like color. If you decide to replace them, they are 18 gauge. Depending on the unit that you have, there may be 2, 3, 5, 7, or 9 wires. Install the wire in 3/8 flex to prevent a repeat. Lowes and Home Depot will sell you the wire by the lenght you need. Ask for jacketed wire.
This should be copper wire and a splice could be made with little risk since the thermostat is a low voltage circuit in most cases. Try the local HVAC contractor for some of the type you need. There are different types ( number of conductors) for different controllers so they need to match. If you just have the HVAC contractor do a fall service on the system they can make the needed repairs and prepare the whole system for the winter. It was probably used a lot this last summer so a service is about due.
