The Building Intelligence Center has been providing resources to homeowners, home inspectors, realtors, plumbers, and other trades since 2003.  From our humble beginnings we have grown to over 35,000 unique visitors to our site per month. Over 1 million have used our site since its inception, making us a top sight for businesses and individuals in determining the date of manufacture, production, or age of HVAC and water heating equipment.

Our Roots

Our founder, Mr. John Bowman, created this site in 2003 with the sole intention of providing a quick and easy method for home inspectors to determine the age of furnaces and water heaters.  A good place to start is to compare your oil or natural gas furnace age to the national average. The average life expectancy of furnaces in homes today is between 16 and 20 years. If a furnace is close to this age or older, home owners should begin shopping. Shopping for a replacement furnace in an emergency does not allow time for you to make your best decision. Most people prefer to replace their furnace as a planned home improvement rather than a panic replacement when your furnace is faltering or has already failed.  The typical lifespan of a warm air furnace will vary based on its operating environment, that’s why it’s important to have the system serviced regularly by a qualified technician. They will be able to properly assess the condition of the furnace and make any recommendations.

Our Volunteers/Supporters – Our Strength

A Lot Of Help From Our Friends…
We’d like to thank organizational friends as well as individual friends for their financial and resource support.  Their generous gifts and research support has enabled us to keep the use of this site FREE.  The Building Intelligence Center is currently maintained by two individuals (John & Bill) who wholly and solely provide full IT and research support.  Their efforts have spanned over 15 years with thousands of hours, but without our friends the task of maintaining and growing this site would be impossible.  A special thank-you to the National Association of Commercial Building Inspectors and Thermographers for their never ending support and to the countless Home Inspectors and individuals that have assisted us in our quest in making this site #1 in determining the date of manufacture, age, or production of HVAC and heating equipment.
