Upstairs system not blowing air due to a bad blower motor. Also, heat exchanger is cracked and filter is located inside the furnace. It’s a high efficiency motor and very expensive and system has a crack in the heat exchanger. System is 13 years old. Sent estimates for potential repairs (not recommend). The best option would be to upgrade the system with 10 years warranty and WiFi thermostat. Set a lead to quote upgrading for tomorrow after 10 am. Customer also wants to zone the system and install a dedicated thermostat in the room above the garage.
