Contacted Mr. Kuhn to work on my air conditioning unit. He was very honest that he might not be able to get to me until the next day. Decided to go with him based on his great reviews on Angie's List. He agreed to contact me if any time opened up on his schedule. Luckily he contacted me early afternoon and was able to work me in - he even gave me time to make it home from downtown Nashville! He met me on time, was very professional and friendly, immediately diagnosed the issue and had the unit up and running very quickly, despite having to go pick up a part. He even checked the freon! His services come with my highest recommendation!!!
