The Index of Sources provides local sourcing information relating to the HVACR industry and related professional trades. The Index of Sources started in 1978 as a small booklet published once a year. Today the online edition has grown to include more than 17,000 companies and brand names from throughout the world and benefits from continuous updating.

Companies are cross-referenced to more than 2,200 categories of heating, air conditioning, ventilating, refrigeration, controls, industrial piping, plumbing, sheet metal, related products and services. Manufactures are cross-referenced to local representatives and distributors. Information about companies, which have merged, changed their name, or gone out of business, is also provided. The Index of Sources is a resource that provides instant insight into where-to-buy, who-sells-what, and who-makes-it, for the HVACR and related industries.

The Index of Sources is not an Internet search engine. A company need not have a web site to be included in the Index of Sources. Whether you’re specifying equipment, estimating a job, or need parts for twenty-year-old equipment, the Index of Sources is your time saving source for sourcing information. The next time you need to find a local source, don’t waste your time calling-around or searching the web, just logon to the online Bydex - Index of Sources.

Any company involved in the manufacturing of products for the trade may be included in the Index of Sources, free of charge. Reps and distributers selling to the Western United States market, are also included free of charge. By its very nature, the Index of Sources is ever-changing.
