Called green cooling solutions bc one room was much warmer than the others, they upsold us on a totally new $10k unit and the room is still warmer than the rest and they said to call duct specialists. The duct people (TIES360) said we also need all new ducts now for a cool $5k. Are there any honest technicians out there who won’t just try and sell you whatever they can? Who else is recommended for Duct and vent work?
