Your best option for choosing a reliable HVAC contractor is to check with friends and neighbors who may be able to recommend a contractor who's done exceptional work for them.

Otherwise, refer to the business section of your phone directory or an online business directory such as switchboard.com, yellowpages.com, superpages.com, yp.yahoo.com, etc. ServiceMagic.com lists prescreened home improvement contractors by category and zip code.

Regardless of how you learn about a contractor, check with your Better Business Bureau to make sure the business is reputable.
