My brand new system stopped working in the middle of winter (less than 6 months old) and when I called them, they told me I'll need to wait more than a week to have someone come and look at it.
We're only 10mins down the road. Surely a service tech can drop in on their way past?!
Having removed my wall heater when they installed it, we now have no way to heat our home with the warmest (not coldest) night between now and then at 8 degrees.
