Your heat pump works all year in Conroe
There is no season off. Heat from November through March, cooling from April through October, the system runs every month to keep up. That kind of nonstop duty adds up on the compressor and the reversing valve, the part that switches the system between heating and cooling. When the reversing valve sticks, the unit blows cold air when you asked for heat, or it won't switch back at all.
Summer afternoons average 93°F here, and the unit has to move heat out of the house against that for hours at a stretch. That load falls on the compressor, and a compressor that struggles under it can trip the breaker or run without cooling the house down. Winter nights average 43°F, cold enough that the outdoor unit relies on its defrost cycle to keep ice from building up on the coil. A defrost control that fails leaves the coil frozen over, and heat output drops off even though the system is running.

Texas requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job, so it is the business and the person running it that TDLR has tested and keeps a record of, not a one-time approval for your heat pump.
A heat pump repair almost always means opening the refrigerant side of the system, and that work falls under a separate federal rule that applies no matter what state you're in. Anyone handling the refrigerant has to hold EPA Section 608 certification. In Texas, that federal requirement sits alongside the state license rather than replacing it.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump puts out air that feels cool compared to a furnace, often close to body temperature, and that is normal. If the air is actually cold, the system may be stuck in defrost or the reversing valve may have failed to switch back to heating. Check that your thermostat is set to heat, not fan only, since a fan running without the compressor will blow room temperature air. If it stays cold after that, the unit needs a contractor to check the reversing valve and refrigerant charge.
- Why is there ice on my heat pump?
- A heat pump forms a light coat of frost during normal defrost cycles in winter, and it should melt off on its own within an hour or so. Thick ice that does not clear points to a real problem, usually low refrigerant, a failed defrost control, or a fan that has stopped pulling air across the coil. Ice also builds up when the outdoor coil is blocked by leaves or debris, so it is worth a look before assuming anything else. If the ice keeps coming back after a normal defrost cycle, have a contractor check the system rather than chip the ice off yourself.
- Why is my heat pump running but not cooling?
- If the outdoor unit is running but the house is not cooling, warm air is likely getting past the indoor coil instead of being pulled through it. A dirty air filter is the most common cause, since it restricts airflow enough that the coil can freeze over and stop cooling. Low refrigerant from a leak causes the same thing, a coil that ices up and blows warm air. Summer afternoons here average 93°F, so a system stuck like this will not catch up on its own, and it needs a contractor to check the filter, airflow, and refrigerant charge.
