Your heat pump works almost every month here
In Killeen your heat pump is either heating or cooling for all 12 months. Summer afternoons average 95°F, so the compressor runs long hours to keep up. Winter nights average 39°F, cold enough that the system switches into defrost and back on its own, over and over, all winter. That switching wears on the reversing valve, and a reversing valve that sticks will leave you with heat when you want cooling, or the other way around.
Most homes here heat with electricity, so when the power goes out, the heat pump goes out with it. Bell County has seen 44 damaging wind events over the past ten years, and across Texas a third of households lost power for at least a day in 2024. After an outage, a heat pump that does not come back on its own often just needs its power reset at the breaker or the disconnect near the outdoor unit, but if it still will not start, the control board may have taken the hit instead.

Texas requires HVAC contractors to hold a state license.
The license belongs to the contractor, not to the job itself, so it does not get reissued or reviewed each time someone repairs a heat pump. It is a standing record kept by the Texas Department of Licensing and Regulation of who is allowed to hold that title in this state.
A heat pump repair usually means opening the refrigerant side of the system, and that calls for its own credential on top of the state license. Federal law requires EPA Section 608 certification for that work, in Texas and every other state. The state license accounts for who the contractor is. The EPA certification accounts for whether they are qualified to handle the refrigerant itself.

- Why is my heat pump blowing cold air?
- In winter, a heat pump moves heat from the outside air into your home, so the air from the vents feels warm compared to the outside air but cooler than your skin. That is normal and does not mean something is wrong. But if the air is truly cold, or stays cold no matter how long the system runs, the unit may be stuck in defrost mode, low on refrigerant, or the reversing valve may have failed. A contractor can check the refrigerant charge and the reversing valve to find out which it is.
- Why is there ice on my heat pump?
- Some frost on the outdoor coil during cold weather is normal. Your heat pump runs a defrost cycle every so often to melt it off on its own, so a light coating that clears up is nothing to worry about. Heavy ice that builds up fast or never melts usually means airflow is blocked, the coil is dirty, or the defrost control has failed. A contractor can check the coil and the defrost board to see which one is causing it.
- Why is my heat pump running but not cooling?
- If the unit is running but the air is not cool, check the outdoor unit first. It could be blocked by leaves, dirt, or overgrown grass, which stops it from releasing heat outside. A dirty filter can also choke the airflow enough that the system cannot pull heat out of the house. If both of those look clear and it is still not cooling, the refrigerant charge could be low or the compressor could be failing, and a contractor will need to check the pressures to know which one it is.
