Sergio showed up promptly for my appointment. He did complete check up on my air cond unit outside as well as checking inside unit. Put in a new filter and used a device to check all my vents to make sure working properly. Very knowledgeable about heater unit also. He explained everything to me and made me feel safer knowing professionals are at work for me. Would recommend Stewart Heating and Air to friends. Very high quality in their products and services and personnel.
