Anybody know anything about wireless thermostats?
We've been in our new house for just over a year. A month or two ago I noticed that our A/C was running nonstop without regard to external or internal temperature (or the fact that I'd set our thermostat to heat instead of cool). I called our HVAC guy who'd installed a new furnace the day we'd moved in, and he was too busy with people who didn't have working furnaces (it was our first cold snap of the winter) to come out right then but said he hoped it wasn't a bad wire in the walls as one of the others had been shorted out when he put the new thermostat in and there weren't any spares left. I said that I hoped so too and shut off the breaker to the AC and didn't think anything more of it.
I guess it slipped the HVAC guy's mind too because he never called back to set up a time to come take a look at it. I was talking with my dad about how I hoped we didn't have to go through the walls to rewire things while I was home over Christmas holidays, and he said he'd heard of a wireless thermostat you could use anywhere in the house and it would talk via radio frequency with a base that you had directly hooked up to the furnace (no rewiring needed), but he didn't know anything more about them than that. Anybody know anything about them? I'd like to have a general idea before I call the furnace guy back so I can have some idea of what I'm talking about (he's sort of an old school guy).
