We had our furnace replaced a few years ago and now want to move our
thermostat. It's against a cold outer wall, and runs our furnace more based
on the outside temperature than the inside temperature.
The thermostat is the type that runs on batteries. There's no power wire -
something we didn't know when we had the furnace replaced. So, I need to
have some wiring done to get it moved and hooked up correctly. Who would I
call to do this? A plumber who does heating/cooling or an electrician?
in the words of the immortal Sgt Schultz:
The difficult part is to run the wire through the wall. In most cases, a
handyman can do this. It is a low voltage setup so an electrician is not
needed. You just disconnect the existing wires and put them back on the
same terminals in the new location.
Except for the less expensive thermostats with a bimetallic strip and
mercury switches, most setback thermostats have both batteries and a
low-voltage control wire harness (allowing for fan, heating and
cooling control). The wire is small guage and typically no more than
24 volts A/C from a small transformer. A simple voltmeter can confirm
what you have.
For low voltage such as this, most of the relocation cost is running
new wire from the furnace to the new location, fishing it down inside
the wall. I would leave the existing line in place until the new
connection is verified as operating properly. Abandon the existing
line by pushing it back into the wall and disconnecting it at the
I would suggest that a heating system installer would be less
expensive than a licensed electrician. They have to be able to perform
this task in new construction.
