Warmer than the coast
La Mesa is about ten miles east of the ocean, and it typically sees hotter summers than coastal San Diego. Many homes that never needed cooling decades ago now rely on air conditioning for summer afternoons. We size new systems to the house and check that the ducts can carry the air.
Older homes and hillside lots
La Mesa has many older homes, from the streets around La Mesa Village to the hills of Grossmont and Mount Helix. Older homes without ducts, or with small ducts, are often good fits for a ductless mini-split or a ducted heat pump. Hillside lots can also make equipment placement a puzzle, and we plan for it.
