Hey guys,
We just moved to a new home with a Carrier 58PAV up-flow gas furnace. The furnace checked out fine before we moved in, so I'm not sure if the way that it's currently operating is normal (and it works in a way I don't expect), or if something is wrong:
Say the temperature in my house is 68 degrees, and the thermostat is set to HEAT at 71 degrees. Well, the furnace stats circulating the air (that is, air is moving through the system and into the house so the blower fan turns on), however it's just the ambient temperature (whatever temp it is in my garage and ducts - but not hot/warm). So, effectively I have this cool breeze blowing through my home! If I set my thermostat up to 90 degrees, then the burners click on and start heating the air. I'm not sure why the 'call for heat' isn't heating for low differences in temperature..?
am I totally nuts? Thanks in advance for your help...!
