Tru-Comfort Inc did an excellent job and I would rate their service a 5. They came in and serviced a piping issue in a unit in our complex and they also changed our filters. They did a good job and I was very happy with them. That's right, one of them also came in for a problem with a motor in a fan that was failing, that's what he did and he was professional with the repair that he did. This is our second or third time using them and we will use them again. They are very good.
