There were positive and negatives with Infinity Solar Heating. On the positive I think they do good work and the employees are all pretty nice to work with. However, we have had trouble communicating with them. They often don't respond at all to my husband's emails and even sometimes to my calls. There are some days that they are available and ready to help, but its very inconsistent. Its frustrating not being able to stay in contact with them, but otherwise they do good work!
