Nine months of work a year wears on a heat pump here
Your heat pump is doing something most homes elsewhere don't ask of it. November through April it runs the heat, July through September it runs the cooling, nine months of the year with barely a break in between. That kind of run time adds up on the compressor and the reversing valve, the parts that switch the system between heating and cooling modes.
Oakland winter nights average 41°F, mild by most standards, but that means the heat pump is cycling on and off all night rather than running steady. Each cycle is a start, and starts are what wear out a contactor or a capacitor over time. If your system is struggling to keep up on a cold night or short cycling instead of holding steady, that is often where it shows first.

California requires HVAC contractors to hold a state license.
The Contractors State License Board tests contractors before issuing a license and keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license that qualifies someone to install a furnace also covers a heat pump repair like this one.
A heat pump repair means someone is likely working on the refrigerant side of the system, opening sealed lines to check charge or replace a component. Federal law requires EPA Section 608 certification for that work, in California and everywhere else, alongside the state license. Between the two, one confirms the contractor is legitimate in this state and the other confirms they are trained to handle refrigerant without venting it or mishandling the system.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump puts out air that feels cooler than a furnace would, so some coolness at the vent is normal even when the system is working right. If the air has no warmth in it at all, the system may have lost refrigerant, or the outdoor unit may be iced over and unable to pull in heat. It could also be stuck in fan-only mode, or it could be running a defrost cycle, both of which push air without heating it. A contractor can check the refrigerant charge and the reversing valve to find out which one it is.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit in cold weather is normal, and the system should clear it on its own through a defrost cycle. Heavy ice that builds up and does not go away usually means airflow is blocked, by a dirty coil, a failed fan motor, or debris packed around the unit. Low refrigerant can also make the coil run too cold and ice over. If ice keeps coming back after you clear it, have a contractor check the defrost control and the refrigerant level.
- Why is my heat pump running but not cooling?
- If the unit runs but the house is not cooling, the usual causes are a dirty air filter blocking airflow, a frozen indoor or outdoor coil, or refrigerant that has leaked out over time. A thermostat set to the wrong mode or a failing compressor can cause the same problem. Start by checking the filter, since a clogged one can starve the system of airflow on its own. If the filter is clean and the coils are not iced over, a contractor will need to check the refrigerant charge and the compressor.
