All went super in the install which was very difficult. All the techs and installers did great wok. I bought the unit , imay not have except for the fact that Jeff Wheeler coordinated the install. His expertise and knowledge made this happen. There was no challenge he did not overcome. I am difficult to please because I demand perfection. I demanded nothing because the perfection Jeff demands of himself and the crew exceeded anything I expected. He is an asset to his profession and his company. He is why I chose One Call Services and will recommend them both.
