What you are feeling is the heat-pump unable to work efficiency below 40 degrees and depending on what type of thermostat and A/C system you have emergency heat will also be running to make up the difference. However this is not always the case depending on what type of system you have and how it?s set up. If you have electric and you run only in the emergency heat mode your energy usage could climb 4 X more in cost $ compared to the energy efficient heat-pump. to answer your question in most cases its okay to use the emergency heat, however learn more about your system and how it operates would be my best advice without seeing it! My advice would be to call the ?licensed? A/C Company who services your system on an annual bases and have it checked out and ask direct questions on your systems HVAC operation or refer to your system owner?s manual. If you do not have an owner?s manual you can go to your manufactures website such as TRANE, Carrier, Rheem, ICP or Goodman website for a copy or you can call them. Regards, Scott
