I would strongly recommend to anyone that they do not work with this sham organization! They were sub-contracted to do work for me, and did a very shoddy job, actually left work unfinished which caused damage to another system in the house. To get that fixed the bill is going to be well over $1000, and they are taking no accountability for repair, and even went so far as to blame the homeowner. Horrible service as well, it took them forever to show up and do work they were way overpaid to do, and then they do horrible work on top of it. I have heard many different complaints about these tools, and would strongly warn anyone that they will get burned by these people, and they should find another more reputable organization to work with.
