About Mission Viejo, CA - Happy to be your hometown Heating & Air Conditioning Contractor!

The land upon which Mission Viejo is developed was part of the 52,000-acre Rancho Mission Viejo. The chain of title to the land dates back to July 27, 1769, when a Spaniard named Gaspar de Portola led an expeditionary force from Mexico across the southern border of the ranch and claimed the land for Spain. After Mexico won its independence from Spain in 1821, a new flag flew over California and a new spirit filled the air. The missions, which had been established to further the spread of the Christian faith, became secularized, and their vast landholdings were granted as ranches to prominent citizens. In 1965, a master plan for Mission Viejo was approved by the Orange County Board of Supervisors. One year later, families stood in line to pay $21,000 for homes on a former cattle range. In April 1966, these pioneering residents moved into the new neighborhoods near the intersection of La Paz Road and Chrisanta Drive.

Mission Viejo is suburban in nature and culture. The city is mainly residential, although there are a number of offices and businesses within its city limits. The city is planned and features a very large number of single-family homes, some condominiums, a two-year community college and a regional mall, The Shops at Mission Viejo.
