HOME AC*HEAT Thermostat Replacement HELP?? Robert Blass 08-28-2008

What I have is a system which is called a "heat pump" but it does have
both heating and air conditioning and it's sometimes called a "central
unit". It has one of those very old mercury switch type thermostats
that adjusts the changing temp by using some old coil-spring like
system and is controlled by sliding the temp knob left or right.

With this type of system [heat & AC] can I replace this thermostat
with a Digital Thermostat?

I've Googled this and cannot come to a good comparison chart or report
on the various Digital Thermostat Replacement products, could you help
me find such a website?

Is replacing the OLD Thermostat with the NEW Digital Thermostat
something I can do myself?
I've done simple things like replacing ac outlets and ac light
switches many times so would this be something I could also do myself?

Oh yeah almost forgot, What is a good price for a Digital Thermostat
for a home AC and Heat system?

And what kind of saving$ would I see by this replacement? I live in
the southeast so we use the AC about 9 months per year.

Let me know if I didn't make something clear, I'll try to.

Thanks

If in fact it is a heatpump, you need a heat pump thermostat. Those
have an extra wire for the change over valve circuit, orange I
believe.
I bought one over the internet, for around $70. You want a
programmable one, so you can set it back when you don't need heat or
cool,
that is where the real savings comes from.
Auto changeover is a nice feature, as you don't have to slide a switch
to go from heat to cool.
I just looked at Ebay & found lots of them.

Last year I replaced an old mercury and spring based thermostat with a
Hunter Auto Temp Heat Pump Model 44760 picked up at Lowe's.

Best money I ever spent. I had to hire an HVAC guy to bring an
additional wire needed for the new thermostat, but even so has paid for
itself in a few months. I am in South Texas.

It's programmable, so I can set 4 daily time slots and decide what
temperature I want for each one. Every day of the week can be
programmed individually, if needed . When reaching the threshold
temperature I set it will switch between heat and cold automatically.

Go for it. Of course Hunter is not the only game in town, but whatever
you choose or find, make sure to have many programming options and auto
switch cold-heat.

This house has people in it 24 hours a day so I wouldn't need to
program it, but would it still help the power bills?

Also, I have special things like emergency heat and a fan setting, is
that a DIY with a new digital thermostat or would I need an
electrician?

thanks
