I am a non technical senior who needs help with a heating problem. I have a split system heat pump here in Dallas. The Heating & A/C folks told me (when I moved in 7 yrs ago) to set my thermostat on "EM" vs on "heat". I guess emergency (EM) is more efficient/economical ??? Am I doing the right thing?
2. Last year, professionals checked the system and found it to be fine. The problem I have is that the system will not turn on when it gets cold. Example: I woke up to a house temp of 61 degrees yet the system was set at 69 degrees. Later that day, the system kicked on.... it did take about several hours to reach 69 degrees... This has happened two days in a row... I also noticed that during the time it did not work, that it "tried" to work... it kicked on and then quickly turned off.
Any suggestions will be greatly appreciated!!
