They came and it took quite awhile to diagnose the problem. He decided to order air switch which he did. After he came back and installed it it still didn't work. When he was checking the hose that connected to another part. A piece that look like calcium was sticking out where hose connected to pipe from the air switch. He pulled out the piece and connected the hose and then everything worked. So a new air switch wasn't needed and left the new one in.
The charge 129.00 for service call and 257.00 for a total of386.00 with discount . I feel I was overcharged .especially where there was not a bad air switch but just a plugged tube. I wouldn't recommend this company.
