Corinth asks a lot of a heat pump, all year
Your heat pump doesn't get an off season here. It's pulling heat into the house from October through April, then pulling heat out from May through September. That's 12 months of run time a year, with the reversing valve switching the system between the two jobs every time the weather turns.
Winter nights averaging 32°F push the system into defrost cycles more often, and each cycle puts a load on the reversing valve and the outdoor coil. Summer afternoons near 89°F keep the compressor working hard for months straight. When a part is already worn, you'll notice it as a system that runs but doesn't get the house to temperature, or one that switches into defrost and doesn't switch back.

Mississippi 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 people it sends out that are on record with the state, not any single repair. Mississippi's Board of Contractors is the one keeping that record, which means a contractor working on your heat pump has been tested and can be checked against a real license number.
Heat pump repair almost always means opening the refrigerant side of the system, and federal law requires anyone who does that, in every state, to hold EPA Section 608 certification. That certification is separate from the Mississippi license. One says the contractor is allowed to do business here. The other says the technician is trained to handle refrigerant without venting it or getting it wrong.

- 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 coming out of the vents is warm compared to outside but cooler than your skin, which can feel cold even when the system is working right. If the air feels truly cold, not just cool, check that the outdoor unit is running and not iced over. A dirty filter, a low refrigerant charge, or a failing reversing valve can also keep the system from heating properly, and any of those needs a contractor to check.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit in winter is normal, and the system defrosts itself on a schedule. A heavy coat of ice that does not clear means something is stopping that defrost cycle, often a failed defrost control board, a stuck reversing valve, or low refrigerant. With winter nights here averaging 32°F, the outdoor coil runs cold enough that a system stuck in cooling mode or low on charge will ice up fast. Do not chip at the ice yourself. A contractor needs to find why the defrost cycle stopped working.
- Why is my heat pump running but not cooling?
- If the outdoor unit is running but the air inside is not getting cooler, the most common causes are a dirty filter blocking airflow, a frozen indoor coil, or refrigerant that has leaked out. A frozen coil will keep the system running while barely cooling at all, and it needs to thaw before a contractor can find the actual problem. With summer afternoons here reaching 89°F, a system that is not cooling right will fall behind fast, so it is worth having it looked at before the heat builds up in the house.
