Your heat pump runs ten months a year here
Shelton homes need heat from September through June, ten months of the year. Winter nights average 33°F, and the compressor and reversing valve carry that load almost without a break, with only a couple months off in summer, when afternoons average a mild 72°F.
Most homes here heat with electricity, so when the heat pump falters, there is often no backup furnace to take over. You notice it as air blowing but not warm, or the unit running long stretches without the house catching up.

Washington requires contractors to register with the state.
That registration puts the business on file with the state and gets them a bond, but nobody tested their heat pump work to get it. It is a record, not a credential.
For a heat pump repair, what actually says the person working on your refrigerant lines knows that trade is EPA Section 608 certification. That certification is federal and required in every state before anyone can open the refrigerant side of your system. Washington's registration does not test for that. The 608 card does.

- Why is my heat pump blowing cold air?
- In heating mode, air from the vents feels cool since it runs well under your body temperature, so that alone is not a problem. If the air coming out is actually cold, the system may have iced up outside or dropped into backup heat because the compressor stopped working. It can also mean the reversing valve is stuck between heating and cooling. A contractor needs to check the refrigerant side to find out which one it is, and that work requires EPA 608 certification.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit during cold weather is normal, and your system defrosts itself on a timer. With winter nights here averaging 33°F, that defrost cycle runs often. If the coil is covered in thick ice that does not clear on its own, the problem is usually low refrigerant, a failed defrost control, or an outdoor fan that is not moving air across the coil. Any of those needs a contractor to diagnose, and fixing low refrigerant means opening the sealed system, which only an EPA 608 certified technician can do.
- Why is my heat pump running but not cooling?
- If the outdoor unit is running but the air from your vents is not cooling the house, the compressor may be running while the reversing valve is stuck in heating mode, or the refrigerant charge may be low. A dirty outdoor coil covered in leaves or debris can also stop it from releasing heat properly, which keeps the system from cooling even though everything sounds like it is working. A contractor can test refrigerant pressures and airflow to narrow it down. Summer afternoons here only average 72°F, so homes lean on this system for heat far more than cooling, and a cooling problem can go unnoticed for a while before it gets caught.
