Where is the thermostat located? Is it in the warm area or the cool
area?


Good thought. If the OP spends the most time in his living area, could
make sense to move the thermostat there.

Given that my home sounds similar to the OP's, and I have similar
problems, I have a question:

Would it be possible to have two thermostats in my home,
which could supply one average reading that would trigger my HVAC
system?

Most heating systems work on a simple on/off switch triggered by the
thermostat. I can think of a way to have each of them set to a different
temperature and connected to an intermediate switch which would require
both to be on before it would turn on the heating system but I can't see
any benefit in doing that. A more complex system would continually
sample the temperature reading at multiple locations and turn on the heat
when the average (or weighted average) reached a specified value. That
might have more benefit but I've not seen any such thing on the market.
Maybe for a Johnson Controls type commercial system but not for homes. I
think it would be less expensive to put in a second heating system.


BTW, my thermostat is in the middle of the hallway where the bedrooms
are.


Is there something about the cool area that makes it loose heat
faster than the warm area (more windows, uninsulated door, etc.)


Given that my home sound similar, I'll bet part of the problem is more
windows, proximity of heat-producing kitchen appliances such as
fridge, stove, and dishwasher, and air leaking through the chimney.
And in my case, the living area is just so dang big that it's harder
to heat or cool, compared to the bedrooms, which are smaller.


or does
the heat simply not get to the cool area?


In my case, the heat gets to the living area, but it's never as warm
as in the bedrooms. In summer, the situation is reversed, except it's
worse: hot living area, cool bedrooms.

That sounds like leakage/loss of temperature differential in the
distribution system. Are the ducts insulated? (Assuming forced air
because it does both heating and cooling.) Or maybe the total volume of
warm air at the starting point isn't great enough?


Hope nobody minds me interjecting my situation in my home. The OP's
situation sounds so similar to mine that my experience may be relevant
and/or I can learn something along with the OP from you other posters.
