Costco

Worst experience ever. $12,000 for a new furnace that doesn't work and they won't stand behind it. Very nice but there's nothing they can do. Really? A big company like Costco and nothing they can do about a new furnance that has broken down already? And, never swtiched out the electrical box like they were supposed to. Install a 135 amp system in a 110 amp box! Hello fire department!
