We have been using Tru-Comfort for our HVAC needs for over 25 years and have been on their maintenance program. Their service in all these years has been excellent, and we know that if something is not right, they will do their best to make it right. They respond to our calls in a timely manner. Everyone we have dealt with is pleasant, polite and knowledgeable. We trust them. It would be nice if all businesses operated like this.
