We had a problem with our garage door not opening and closing completely. I called Mac Garage Door Company ask if they could troubleshoot and fix it. The installation crew that came over recommended replacing the spring, which they did on a return visit ($200). Several days later the door still had the same issues, including the door not going all the way up. I ended up at Lowe's to buy a replacement opener ($200) and had the same people install it ($200). It seemed to fix the problem but only for a few days. The motor made a noticeable humming sound and quit working. I called their office to ask if the installers could come back to my house to troubleshoot. The person who answered said he would send someone over to look at it but after two days of waiting no one appeared. I called another company this time to replace the opener I bought at Lowe's. This company sells a different brand than Lowe's does which works better and is quieter. The installer told me that the chain I bought for the one from Lowe's was for a 7-ft track and not 8-ft, which is in my garage. At this point I'm in for a spring I didn't need, a non-working motor, and another $200 to install it. The latest motor was $750, which included installation. So now, the total bill is $1,350 for a spring I didn't need, a new motor that stopped working, and installation. Mac Garage Doors probably didn't want to send someone to my house to troubleshoot the motor since it wasn't one they sold, but it would have been nice if they were here to look at it and give their recommendation. I even said that I would pay for a service call. So, all-in-all it wasn't a good experience with Mac Garage Doors and won't use them again. read more
