Hi, I have a Carrier Infinity furnace with the Infinity thermostat. I have had several issues but my current question relates to system staging. In the thermostat, the maximum stages per hour is set at four and the staging has the options of "system, low, medium, or high". My house is only about 1900 sq. ft. but I was still having a problem with not getting enough heat to the back bedroom and bathroom so the staging was set to high. It solved the problem but the furnace became VERY noisy every time it ran. In addition, I suspect that it is far less efficient and more expensive to run it on high all of the time than to let the system decide what it needs to do. So, after about three weeks of it running on high, I put the staging on "system" tonight; assuming the system will decide what it needs to be running on based on need. It is running more quietly but does not feel like it is heating as well. So, the question is, is it less efficient to run the furnace with the staging set on "high" or does it really not make a difference? Where should it be set?
Part of the reason I am concerned about it is that this furnace runs almost all of the time. The anticipator was moved up to 8 and it still short cycles all the time. The dealer is working on that piece but I would like to better understand the implications of the various staging settings toward efficiency of and cost to run the furnace, particularly since it runs almost all the time!
Thanks for taking the time to help!
