What we see in Berkeley homes
Climate. Berkeley has a mild coastal climate, cool summers (65–75°F near the bay, warmer in the hills), mild winters. Heating is more relevant than cooling here.
Housing stock. Historic bungalows, Craftsman homes, and mid-century housing dominate. Many homes have no existing AC, ductless is the standard solution. Strong electrification interest.
Typical systems. Ductless mini-split first installs, heat pump water heater coordination, furnace replacements with heat pump conversions.
Why ductless dominates here
Berkeley housing is mostly Craftsman bungalows in the flats and mid-century homes in the hills, both eras built without central ducting. Adding ducted forced-air to a 1920s plaster-wall Craftsman means tearing into walls and ceilings, and the resulting system rarely justifies the disruption. Ductless mini-splits skip the duct problem entirely. Each indoor head handles a zone; the outdoor condenser sits on the side or back of the house. For new ductless installations here, we use Mitsubishi Electric and check the selected model’s sound ratings and placement against the rooms it serves. We continue to repair and service existing Daikin mini-splits.
What we see on calls
Heating service is more frequent than cooling here. The bay influence keeps summers cool enough that AC isn’t the year-round priority. Older furnaces (often pre-2000s gas units) hit the heat-exchanger inspection threshold at 18 to 20 years; we run combustion analysis and CO testing on every gas furnace call. When a Berkeley homeowner is replacing an aging gas furnace, heat pump conversion is usually the cleanest path, and we work with BayREN and PG&E rebate programs to bring the out-of-pocket down where eligibility lines up.
