Thank you I was looking installers in the state of Virginia
Paul
More information on IID installation in Virginia has been included. Thank you for the request!
I need information on the price of the device and installation cost. I live in North Carolina and would like the nearest location to Asheville, NC (NC, SC or TN).
Can these be bought used?
Thanks.
Sorry for the delayed response. I don’t have a full list of approved IID installers in North Carolina, but there is a Monitech, Inc. installer in Asheville. The contact number is 1-800-521-4246. Typically, these devices aren’t bought at all, but rather are leased. The cost of leasing from Monitech is about $200 at installation for labor and the first month and $60 per month after that. I hope this is helpful. I will try to update the list with more providers in NC soon.
I wanted to know the places in INDIANA it can be installed at…also an estimate on price?
Thanks, Christina! I’ll get Indiana IID installers along with a price estimate or at least a range of prices shortly.
I’m also looking for installed of the devices in Indiana. preferably near the fort wayne, IN area.
