Your heat pump works nearly all year here
Oak Harbor needs heat from September through June, ten months of the year. Winter nights average 35°F, and on those nights your heat pump is cycling on and off for hours to keep the house warm. 57.9% of homes here heat with electricity, and a lot of that load runs through the heat pump.
All those hours wear on the reversing valve, the part that switches the system between heating and defrost. When it starts to fail, the unit runs but stops warming the house, or it gets stuck blowing cold air on a cold morning.

Washington requires contractors to register with the state.
That registration means the business is on file with the Department of Labor and Industries. It does not mean anyone tested the contractor's skill at the trade. No state exam stands behind the name on the truck.
For a heat pump repair, the thing that actually covers the skilled part of the work is federal, not state. Anyone who opens the refrigerant lines to check charge or replace a component has to hold EPA Section 608 certification, and that rule is the same in every state in the country. Washington's registration tells you the business is on file. The 608 card tells you the person working on your refrigerant lines was tested on it.

- Why is my heat pump blowing cold air?
- In heating mode, air from the vents is naturally cooler than your skin, so it can feel cold even when it's working right. If the air is actually cold, or cold enough that the house isn't warming up, the system may be stuck in defrost, low on refrigerant, or the compressor isn't running at all. With winter nights here averaging 35°F, a heat pump that isn't producing real heat needs attention quickly. A contractor who holds EPA 608 certification is who you want checking the refrigerant side of it.
- Why is there ice on my heat pump?
- A thin coat of frost during a defrost cycle in cold weather is normal, and it should melt off within a few minutes as the unit runs its defrost mode. Ice that stays, builds up thick, or covers the whole outdoor coil means something is wrong, often low refrigerant, a failed defrost sensor, or airflow blocked by a dirty coil or a fan that isn't turning. Running a heat pump with heavy ice on it can damage the compressor, so it's worth having someone look at it rather than waiting for it to melt on its own.
- Why is my heat pump running but not cooling?
- If the outdoor unit is running but the air coming out inside isn't cool, check the air filter first, since a clogged one starves the system of airflow. Beyond that, low refrigerant from a leak, a failing compressor, or ice on the outdoor coil can all keep a heat pump from cooling even while it runs. Summer afternoons here only average 71°F, so most homes lean on the heating side of these systems far more than the cooling side, which means a cooling problem is worth diagnosing rather than guessing at, since it points to something specific.
