Roseville asks a lot of a heat pump
Your heat pump works ten months a year here. Heat from October through May, cooling in July and August, with barely a break between one and the other. Most systems get a rest. Yours does not.
Winter nights averaging 32°F mean the system runs in reverse for hours at a time, pulling heat from cold air. That is harder on it than straight cooling, and it is why the reversing valve and the defrost control tend to be the parts that fail first here. When one of them goes, you will notice the unit blowing cold air in the middle of winter, or ice building up on the outside coil and never melting off.

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 system also covers repairing one.
For a heat pump repair, the license is what stands behind the work in California. If the repair involves opening the refrigerant side of the system, which most heat pump repairs do, the technician also needs EPA Section 608 certification. That certification is federal and applies in every state, so it comes on top of the California license, not in place of it.

- Why is my heat pump blowing cold air?
- In winter this usually means the unit is stuck in defrost mode or has switched to backup heat that hasn't kicked in yet. A heat pump also blows air that feels cool compared to a furnace even when it's working right, since the air coming out is warm relative to outside air, not hot like gas heat. If the air is actually cold and stays that way for more than a few minutes, the reversing valve may be stuck in the wrong position, or the system could be low on refrigerant. A contractor can check the reversing valve and refrigerant charge to find out which it is.
- Why is there ice on my heat pump?
- Some frost during a defrost cycle in winter is normal, especially on nights when temperatures drop toward freezing. The unit should clear this on its own every hour or so by briefly running in cooling mode to melt it off. If ice is building up faster than it melts, or covers the whole coil, airflow across the coil is likely blocked, either by a dirty filter, a failing fan motor, or low refrigerant. A contractor can tell whether the defrost control itself has failed, since that's what usually causes ice to keep piling up instead of clearing.
- Why is my heat pump running but not cooling?
- If the unit runs but the air isn't cool, the most common causes are a dirty filter restricting airflow, low refrigerant from a leak, or a failing compressor. On hot summer afternoons, a system that's already low on refrigerant or partly blocked will struggle the most and may seem to stop cooling altogether. Check the filter first, since that's the one thing worth ruling out yourself. Anything involving refrigerant or the compressor needs a licensed contractor, since refrigerant work requires certification and the wrong diagnosis can damage the compressor further.
