This company was used for heating and cooling system when we were building our house. They did an excellent job on instillation. They are very prompt to return any phone calls and quick to make a trip out to check on any problems we are having. The repair man that has been out was wonderful at explaining how the system works so we could get an idea of what was going on and where things were going wrong when we were troubleshooting. They definitely stand behind their products and offer great customer service.
