About Lake Forest , CA - Happy to be your hometown Heating & Air Conditioning Contractor!

Lake Forest, which gets its name from the two lakes located there, is a city in Orange County, California. Both of the lakes mentioned above are man–made lakes and their shores are lined with condos, both big and small. The ″forest″ for which the city gets the second part of its name contains mostly Eucalyptus trees. It was started when, in the early 1900′s, a landowner planted 400 trees as part of a lumber operation. In the 1960′s a residential community was developed by Occidental Petroleum in and around the forest. Lake Forest has been ranked among the safest places to live by two different law firms, one which ranked it 15th and the other ranked it 10th.

A new commercial district, known as Arbor at Lake Forest, was recently opened making it possible for Lake Forest to compete with shopping in surrounding cities. The city is home to the headquarters of many big businesses including Oakley, Inc, Panasonic Avionics, Etnies, and Tilly′s. The eighth largest church in the United States, Rick Warren′s mega church, Saddleback Church, is located in Lake Forest. Among the city′s top employers are Western Digital, Apria Healthcare, and Eyeshot. There are plenty of recreational areas located in Lake Forest also, including Etnie′s SkateparkSleepy Hollow HikeWhiting RanchHeritage Hill Historical Park, as well as several community parks. Lake Forest experiences a Mediterranean climate with year round average temperatures in the high 60′s and mid to low 70′s. Several famous people, such as Olympic medalists Elaine Young and Kaitlin Sandeno, rock bassist for the Smashing Pumpkins Ginger Reyes, have called Lake Forest home.
