Initially I had problems in setting up appointment with the company, probably due to email communications issues. But the company recognized and rectified its mistake, and everything went smoothly after that. The tech did a great job in installing the electrostatic filter and the humidifier for my house furnace. Dave, the owner, later stopped by to make sure the work was done right, and to show me how the new filter/humidifier system worked. He also took the time to explain to me how the overall furnace air flow worked and gave me a few good tips on how to save energy. The price was also reasonable. Everyone makes mistakes. What counts is that the person recognizes and corrects the mistakes. And this company came through where it really counts. I would use this company again, and recommend to others.
