I'm very pleased with the service I received from Duane at Sierra Air, he's pleasant, polite, and efficient. He made two trips here. The first was to diagnose the problem with my gas furnace and to give me a repair quote. He was very understanding when I told him I had to acquire financing for the repair and told me to give him a call when I had the funds. Two days later, I called and he was on his way. Not only did he repair the broken part of the furnace, he was extremely thorough and checked to make sure that it had no gas leaks or any thing else that might be weak and cause problems later.
