About 4 years ago we replaced our aging dual fuel heat pump system with a modern system . It is an 18 SEER Goodman with propane furnace . So during warm weather AC cools the house .
During cold weather down to around 30 degrees the heat pump does the heating . Think reverse AC . Our system does NOT have backup heat strips . Instead it has the propane furnace as backup . There is software programming that tells the system when to switch from heat pump to furnace .
It is a seamless transition and works very well for our weather here in north Georgia . The system is so efficient that our electric bill on average is $50.00 less per month vs our previous system . We also went from previous 10 SEER to current 18 SEER so major efficiency upgrade .
