We recently purchased a tri-level house built in 1955.

The thermostat is located in the mid level of the house, and is set at 77
degrees.

The bottom level is the garage and media room; the mid level is the kitchen,
dinning room and living room; and the bedrooms and bathrooms are in the top
level.

By the time the thermostat detects that it needs to cool, the bedrooms can
get as high as 84 degrees. By the time the thermostat detects that the
cooling can turn off, the lower levels of the house are a chilly 72 and the
bedrooms are still only down to about 79. The thermostat reads 77 degrees
the whole time.

What is the best way to regulate this temperature zoning problem?

Would installing exhaust fans in the upper bedrooms to remove the warmer air
be best, or should I look into a system that supports multiple climatic
zones?

The biggest annoyance is at night, when the outside temperature can get
below the thermostat setting. If the outside temp drops to 75 degrees, the
temperature at the thermostat does not get below 77, so the bedrooms stay at
84 degrees, cooking us all night long.

I'm looking for ideas, and the pros and cons with each idea.

Regards,
~Joe

        By getting a professional in to diagnose the design or
operational problems, and fix them.

        I'm reminded of a call I was on once for a noise from air
handler complaint. The lady mentoined in passing that the living room
/ kitchen / that side of the house never cooled or heated right, in
three years. While looking at the AHU for the noise, I noticed a
plenum damper closed 100 % to that side of the house. Duh. Opened
it, told the lady how to adjust it after giving it a day or two to
equalize

Wasn't the helpful answer I wanted.

Sounds like you support the idea of paying someone who is licensed for this
to do the job because you are licensed.

If so, your answer is lame.

        I'm SOOOOOOooooo sorry about that. Would you like a fucking
refund ?


>Sounds like you support the idea of paying someone who is licensed for this

        I support the idea of someone with a fucking clue looking at
it. This means that it will be someone other than you.


>If so, your answer is lame.

        My answer is A ) the best you'll ever get, and B ) the only
one that will solve you problem. Well, your AC problem, anyway. Your
problem with being an asshole, I can't help.

        Now - piss off.
