A technician from BC Express Inc Heating & Air Conditioning recently came over and did some service work on my air conditioner. I saw a commercial for them during the winter time, and I told myself that, when the time came to turn my A/C back on, I would sign a contract with them to make sure it's running fine. It was a very good experience, as the tech was very nice and didn't wast a lot of time. I asked him about the heat vents I have that come out from the floor, and he was very honest in not being sure if it was something his company can service. Overall everything came out fine, and I will continue to use them.
