I called Avondale Garage Doors on a warranty issue with 1 of the 2 openers they installed for me over 6 months ago. I told them I was hearing a sporadic loud popping sound, accompanied with my door freezing midway. Mind you this only happened at most twice a week.
The owner came to my house diagnosed the problem, fixed it and provided maintenance on both doors and openers at no charge.
Great timely customer service and I highly recommend this company.
