I worked with Kristin Casey and R&D Heating and Cooling and she was a really big help. Not only did she take on figuring out what I needed at 3 houses, what timing I needed and so on, but I gave her a budget after that and she went back and really figured out how to get to keep costs within my budget for the 3 units. As far as the setup and installation, 2 houses are already done and were finished on time on the dates they promised. The 3rd house is delayed and I think there are some issues, but I'm hoping it will be worked out soon. I would very quickly contact Kristin in the future for this kind of job. I like having sales person to contact, it's a much easier way to approach them. If it's just a phone number for an office, that won't work the same way. One of the big benefits for me is that I can text her with questions and she will respond, and that makes my life much easier.
