See question posted. Brand new furnace runs all the time and we can not get a warm house any longer. This after having replaced a 23 yr old Carrier. As mentioned the installer's technicians have been out several times. The pressure was increased from 1.2 to 1.5 stage 1 and from 3.2 to 3.5 stage 2. Honeywell tstats have been exchanged. But we are still cold and uncomfortable in a house where we have always been warm and comfortable.
