Central OC spans 1960s–70s tracts in Garden Grove, Santa Ana, and Westminster through Irvine's newer master-planned villages, so system ages vary widely street to street. Slab-on-grade construction is standard, keeping slab-leak detection in demand. HOA communities often have placement and noise rules that affect condenser and heat-pump installs.
