Gerry the field technician was great. Clearly knew what he was doing and solved the problem right away. I only give three stars because I found the price to be quite high in comparison to other groups. I could have taken the time for another quote, but I still would have needed to pay the call out fee and take another half day away from work. I would happily recommend them if something needs to get done right and fast, but if you have the time I would suggest looking for a less expensive company.
