Last fall we replaced our 30 year old systems with new top end systems from Trane and Reliable Air. The sales person did a great job of helping get things the way we wanted, relocating thermostat and selecting systems. The systems are great when working but shuts down and requires power to be turned off and on to restart. They have not been able to fix. This is ridiculous as we have not heat until that is done. Keep your old system until it dies. New is not better!
