Your heat pump runs every month of the year here
In Clark County the heat pump never really shuts down. It runs the cooling side through summer afternoons that average 98°F, then switches to the heat side on winter nights that average 37°F. That switchover happens on its own, and the reversing valve is what makes it happen. A valve that sticks will leave you with cold air when the thermostat is set to heat, or a system that will not switch back come spring.
Most homes here heat with gas, so the heat pump's winter work is often lighter than its summer work. But the cooling season runs six months, and afternoons that stay near 98°F put steady load on the compressor and the outdoor fan motor. When one of those starts to fail, you notice the air is not as cold as it used to be, or the outdoor unit is running but barely moving air.

Nevada requires HVAC contractors to hold a state license.
The Nevada State Contractors Board tests and licenses HVAC contractors before they can legally take on work like this. The license belongs to the contractor, not to any single job, so it travels with them from one repair to the next rather than being issued fresh each time.
Heat pump repair almost always means opening the refrigerant side of the system, and federal law requires whoever does that to hold EPA Section 608 certification, no matter what state they work in. In Nevada, that certification sits alongside the state license rather than replacing it. Between the two, a contractor working on your heat pump has been checked both on the trade generally and on handling refrigerant specifically.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump usually needs to switch from cooling to heating, and if it is stuck in the wrong mode or the reversing valve is stuck, it will keep blowing cold air. It can also mean the outdoor unit has iced over and cannot pull in heat, or the thermostat is calling for the wrong mode. A contractor can check the reversing valve and refrigerant charge to find which one it is.
- Why is there ice on my heat pump?
- Some frost on the outdoor coil during a cold run is normal, and the unit should clear it on its own through a defrost cycle. Heavy ice that does not go away usually means the defrost control, a sensor, or the fan is not working, or the refrigerant charge is off. On a night near 37 degrees, a heat pump that cannot defrost itself will keep icing over and lose its ability to heat the house.
- Why is my heat pump running but not cooling?
- If the unit is running but the air is not cold, low refrigerant, a blocked outdoor coil, or a failing compressor are the most common reasons. A dirty filter or blocked vents can also cut off enough airflow that the house never cools down even though the system is working. Only a technician with EPA 608 certification can check the refrigerant side, since that requires opening the sealed system.
