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.
