The office called with an approximate arrival time the morning of my appointment and the technician called ten minutes before his arrival. The work on my furnace was done efficiently and the technician advised me that I should change the humidifier filter. Only then did he ask if I wanted it replaced. When the work was done he offered me a one year contract which includes an A/C inspection in the Spring at a discounted rate. I was very satisfied with the service. Gary H-Mokena, IL
