Master-planned and inland
4S Ranch is an unincorporated, master-planned community just outside the City of San Diego, about 13 miles from the ocean. It borders Rancho Bernardo to the east, Black Mountain Ranch to the west and Rancho Peñasquitos to the south. Being that far inland means warm summer afternoons, and most homes rely on central air conditioning.
Two-story homes and HOAs
Many 4S Ranch homes are two-story tract homes, with equipment in attics and side yards and HOA rules for what shows from the street. Many original systems are now old enough to need a careful look. We check airflow, ducts and electrical service, and we'll explain whether a high-efficiency AC or a heat pump fits your home.
