Your heat pump works almost every month here
In Denton County the heat pump runs from November through March to keep the house warm, then switches over and runs May through October to keep it cool. That is 11 months a year the system is doing something, with barely a break between seasons to rest.
Winter nights averaging 36°F mean the heat pump is drawing heat from cold outside air on a regular basis, which asks more of the compressor and the reversing valve than mild weather would. Then summer afternoons averaging 94°F push the system the other direction, running the compressor hard for hours to keep up. More than half the homes here heat with electricity, so when the heat pump falters, there is no backup furnace quietly taking over. And with a third of Texas households losing power for 24 hours or more last year, a storm knocking out electricity can leave a heat pump home cold or without any way to cool down.

Texas requires HVAC contractors to hold a state license.
TDLR tests the contractor before issuing the license, then keeps a record of who holds one. That record follows the contractor, not the specific job. The same license covers this repair and the next one they do somewhere else.
A heat pump repair usually means opening the refrigerant side of the system. That work requires EPA Section 608 certification, no matter what state the work happens in. This certification is separate from the Texas license. The state license puts the contractor on record and accountable for the work. The EPA certification is what says they are allowed to handle the refrigerant itself.

- Why is my heat pump blowing cold air?
- In winter, this usually means it's stuck in defrost mode or the reversing valve isn't switching over the way it should. A heat pump can also feel like it's blowing cold air when it's simply running at a lower supply temperature than a furnace would, which is normal, but if the air feels genuinely cold at every vent and stays that way, the reversing valve or a refrigerant issue is a likely cause. A contractor can check the valve and refrigerant charge and tell you which one it is.
- Why is there ice on my heat pump?
- A thin coat of frost during a defrost cycle on a cold morning is normal, especially with winter nights here averaging 36°F. Ice that stays on the coil, or that builds up thick and doesn't clear on its own, points to a defrost control problem, a low refrigerant charge, or airflow blocked by a dirty filter or a coil that needs cleaning. Running the unit with heavy ice on it can damage the compressor, so it's worth having a contractor look at it rather than waiting for it to melt off on its own.
- Why is my heat pump running but not cooling?
- If the outdoor unit and indoor fan are both running but the air coming out isn't cold, the most common causes are a low refrigerant charge, a dirty outdoor coil, or a failing compressor. With summer afternoons here reaching 94°F, a unit that's low on refrigerant will struggle to keep up and may run long stretches without ever cooling the house down. A contractor can check the charge and the coil and find out which part isn't doing its job.
