Dylan, was very professional. Tried to break the cost of the new part gently to me. But over $1, 500.00 is a hard number to swallow for a 11 year old furnace. I think carrier is off of my list for my next furnace and AC.

Called Interstate on 9/24 for an estimate on a whole house humidifier replacement and an attic fan problem. They said they would email me an estimate. It’s 9/30 and not a peep. No follow-up from customer service to check on the quote status.
Shows lack of respect for customers and poor internal processes.
