Welcome to the Bay Air HVAC website. This page defines the purpose of this website, the professional knowledge and experience of its author and how it can help you to gain a greater understanding of the equipment available for keeping you comfortable in your home or workplace whatever the weather is doing outside

The original website described the physical company based in the Bay Area, but that website expired some years ago and its domain dropped from the resister, becoming available for purchase by anyone with an interest in its core subject. The new owners of this domain have recreated the basis of the website from archived material, but have 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.

The new site focuses on that same equipment and service, but is not linked in any way to a physical HVAC company. 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.
