The short answer
ClearSky installs ducted, ductless and dual-fuel heat pumps in Campbell homes after sizing the house and checking ducts and electrical capacity. Air District furnace rules favor heat pumps from 2029, though nothing forces you to replace working equipment.
The best time to switch a Campbell home to a heat pump is before you are forced to. When a furnace dies in January or an air conditioner gives out during a hot spell, decisions get made in a hurry. Planned on your own timeline, a heat pump project lets you compare equipment, sort out electrical capacity, and fix duct problems properly. ClearSky Heating & Cooling designs and installs ducted and ductless heat pump systems in Campbell, about eight miles south of our San Jose base. One machine handles both seasons: it moves heat out of the house on dry summer afternoons and pulls heat in from outdoor air during the valley's mild, damp winters.
Why heat pumps suit Campbell's weather
Heat pumps are most efficient when winter temperatures stay moderate, and the Santa Clara Valley's Mediterranean climate fits that profile well. Freezing nights are uncommon on the valley floor, so the system spends most of the heating season in the range where it performs comfortably. In summer, the warmer inland conditions that Campbell shares with the southern valley are exactly what a heat pump's cooling mode is built for.
There is also a regulatory reason many households are looking now. Under Bay Area Air District Rule 9-4, natural gas furnaces manufactured from 2029 must meet a zero-NOx emission standard, which in practice points homeowners toward heat pumps when a furnace is replaced after that date. The rule does not require replacing equipment that still works, so you can plan the change when it suits you.
Choosing a system type for your house
There is no single heat pump layout that fits every home in 95008. The right setup depends on whether you have ducts, how they are routed, and how the rooms are used. We usually narrow it to one of these options during the first visit.
- Ducted split heat pump: replaces both the furnace and the AC condenser, using your existing duct system for whole-house comfort
- Ductless mini-split: individual wall or ceiling heads, ideal for additions, converted garages, or homes without ductwork
- Mixed system: a ducted unit for the main house plus a ductless head for a room the ducts never reached well
- Dual-fuel setup: a heat pump paired with an existing gas furnace that serves only as backup, for owners not ready to remove gas yet
The pieces of a heat pump project people overlook
Electrical capacity comes first. An all-electric heat pump draws more from your panel than a gas furnace did, and some older Campbell homes have panels with little room to spare. We check the panel, the available breaker space and the wire run to the outdoor unit, and we tell you early if an upgrade or a load management device is needed.
Ducts come second. A heat pump delivers heat at a lower supply temperature than a gas furnace, so it relies on steady, ample airflow. Leaky or undersized ducts that you tolerated with a furnace can make a heat pump feel lukewarm. Sealing joints, adding a return, or replacing damaged runs is often part of a good installation.
Finally, think about the water heater. Small water heaters fall under a separate Air District rule, Rule 9-6, with a zero-NOx date set for 2027. The Air District Board is considering amendments in November 2026 that could delay that date, so check the current rule before planning a water heater replacement alongside your heat pump.
From first visit to first heating cycle
We begin with a load calculation for each room, an inspection of the ducts and attic, and a look at the electrical panel. You then receive a written proposal describing the equipment, the work involved and the permit steps with the City of Campbell. On installation day, we remove the old furnace and condenser, set the new indoor air handler and outdoor unit, run refrigerant lines and wiring, and connect the condensate drain.
Before we leave, the system gets tested in both heating and cooling modes. We verify the refrigerant charge, measure airflow, configure the thermostat for heat pump operation and show you how the defrost cycle looks so it does not surprise you on a damp winter morning.
Incentives: what to know right now
The federal 25C Energy Efficient Home Improvement Credit applied to qualifying heat pumps placed in service before December 31, 2025. It is not available for installations after that date. Local help may still exist: BayREN and your clean energy provider periodically fund heat pump and electrification incentives. Amounts and availability change by funding cycle, so we confirm the current offer before quoting it. We also install throughout Los Gatos, Monte Sereno, Saratoga, Cupertino and Santa Clara.
