I am a very pleased customer! Nestor is prompt, knowledgeable, courteous, and efficient -- diagnosing and repairing an unusual electrical problem that prevented my heat pump from turning on. I also have to mention that I received the service call just a few hours after I phoned the office, instead of having to wait several days for an appointment as with another company. Will MOST DEFINITELY RECOMMEND B&B Air Conditioning & Heating to everyone!
