Reflective Insulation

Will regular insulation from a store work to cover A/C wires from unit to the house?

My dog chewed the insulation off the wires/hose that runs from my a/c unit to the house. Can I use regular foam insulation from a hardware store or do I need to contact an A/C repair person to get the thicker insulation that was originally on there?

1. You need to find a real 'electrician' supply house...not Home Repo or Wallyworld...and ask for EXTERIOR grade wrap insulation. If ANY of the wires got chewed down to the metal, don't mess with it-call your electrician or A/C man and have the wires REPLACED...exposed wires WILL eventually contact water and arc and short. IF the wires are NOT chewed down, I'd wrap them firmly with exterior black electricians tape, THEN add the exterior grade insulation. Then move the dog run somewhere else in the yard!
2. If you dog eat the insulation off the electrical wires you will need to train your dog not to do that or you may not have a dog for long. As for the electrical wire they should be replaced. If it was the black pipe covers that cover the condescend line that is easily replaced. The only thing you need to make sure is if the insulation is OK to be in sun light. If not it will not last long.
