I have a 2.5 ton Trane XR15 that's about a year old. When heat is needed, which is not very often in south Florida, I only get warm air blowing to one room. The handler is blowing warm air at the source, but the tech is saying because the unit produced is specific to a warm weather area it runs at a higher fan speed. So warmer air is not dispersed equally to ducts, it depends on the length of the duct. So some rooms heat up, and others do not. And the thermostat is in a room which does not get warm air, so it runs pretty much until the overload fuse blows.
The cooling works fine. I've never heard of such a thing with the heating issue. The unit that was replaced did not have any issues with heating.
Is there truth to what I'm being told, or am I getting my chain yanked?
Thank you in advance
