Elec. heat v. Gas heat
I have a heating element in my a/c and gas heat. If I turn on the elec. heat, will the system automatically switch to gas heat if the temperature drops below a certain degree?

Heat pump roof top units will only work to about +40 f otherwise thet freeze up as they do not have a defrost cycle. Most thermostats then switch to furnace heating then back to heat pump when the day warms.
If cost is a factor, calculate resistance heating at 5160btu/ kwh, 80 % of 91502/gal btu for propane, heat pump @ 8200btu/ kwh roughly depending on unit.
Given that in our market that propane fills are $3.50/ gallon and elec. is ,15/kw, then its equal with propane furnace heat output, no savings.
Market price for power, propane and temps. you are in are your search. It may be in some places better to heat with propane. Other places electric . heat pumps are generally best when they work.
Know the costs and how your system works.
