I bought a house that has a newly installed Trane air heat pump and an electric furnace emergency backup.
As far as I'm concerned I don't want the HVAC company that installed it to look at it as they want to charge me for an incompetent setup.
The way its set up is the heat pump runs whenever the stat is calling for heat...even down below temps in the teens and colder when the heat pump is obviously useless...it still runs along with the electric furnace. This is a horrible waste of electricity and I figure is costing me about 30% more on my electric bill when the outside temp is that cold.
Anyone know of a thermostat that I can install that is inexpensive as possible that will lock the heat pump out when the electric furnace kicks on? Or one that I can install an outside sensor and the heat pump kicks off at a certain temp and tells the backup to run?
Thanks
