I called at 8:00 am to get a service appointment for my malfunctioning air conditioner; All-In -One had a repairman at my house at 11:00 am. The polite, well spoken, clean, tidy serviceman diagnosed and repaired my air conditioner's dead condenser in 15 minutes, and, although my air conditioner is old, the serviceman did not try to talk me into buying a new one, but instead gave me a brochure from the company offering a service and parts contract. I am delighted with the speed of the service (I'm a new customer) and the competency of the repairman. I will definitely use All-In-One again.
