We install ducted, ductless, and multi-zone heat pumps sized to the building, not the brochure.
We handle full electrification, including panel coordination, refrigerant lines, and duct verification.
Our team diagnoses refrigerant, inverter board, and control issues on all major brands.
Seasonal service covers coil cleaning, refrigerant check, filter, and control verification.
ABC Service designs heat pumps around real load calculations and the Bay Area's mild but variable climate. We install ducted, ductless, and multi-zone systems from Mitsubishi, Daikin, Bosch, and Carrier — sized to the building, not the brochure.
Most furnace-to-heat-pump retrofits require electrical planning. We coordinate panel capacity, run dedicated circuits, verify or upgrade existing ductwork, and integrate with EV charging and heat-pump water-heater plans so the whole electrification path stays clean.
Our team diagnoses refrigerant, inverter-board, and control issues on variable-capacity systems from all major brands. Inverter-driven equipment requires manufacturer-specific service tools and a measurement-based approach — not the swap-and-pray method common in the trade.
We commission and maintain every system with instruments: refrigerant verification, static pressure, balance point, and control logic. That work is the difference between a heat pump that performs and one that disappoints.
Heat pumps are the cornerstone of an all-electric home and the lowest-carbon way to heat and cool in California.
Heating and cooling from a single piece of equipment — simpler, cleaner, and easier to service.
Properly designed heat pumps deliver 2.5–4× efficiency compared to resistance heat or older AC equipment.
Rebates and tax credits often cover a meaningful share of the project cost when documented correctly.
