Solved the problem of my heating system sounding like a 747 taking off! Joshua and his assistant first checked out the system to make sure it was functioning as expected and then spent some quality time with the manual and the dual zone control. He was able to change some settings in the system and the heat now comes on gently and quietly. This saved us a lot of money and got the result we wanted. He made some other suggestions and provided a quote to improve the system. I will be calling them back for my annual AC tune up.
