Bay Air Heating & Air Conditioning

The website in its original guise described the physical company based in the Bay Area of San Francisco CA. However, that website expired some years ago and its domain dropped from the register, becoming available for purchase by an entity with an interest in its core subject.

The new owner of this domain has recreated the basis of the website from archived material. He has brought the design up to date and replaced the original text with new content that is now original and copyright by the current author.

The original company provided locally based air conditioning, ventilation, heating, refrigeration, air purification and professional engineers to service, repair or maintain home or business equipment.

Please bear that in mind when reading the freely available material that we have provided for your information should you wish to learn more about heating and cooling equipment, systems, design and layout and the best practices in their use for economy and efficiency.
