Customer Question

Seems to be no power coming to HVAC unit after (attempting to) change to a new thermostat. Worked before, wanted to upgrade the old Honeywell to a Nest.
JA: Thanks. Can you give me any more details about your issue?
Customer: Nest didn't recognize the red wire (power), since removed unit, used voltage tester, not getting a reading from wire or directly from electric panel on side of furnace.
JA: OK got it. Last thing — HVAC Technicians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
