Eleven months of work, most of it in the heat
Your heat pump runs almost year round in Picayune, heat from November through March, cooling from May through October. Summer afternoons averaging 91°F mean the outdoor unit spends most of its life moving heat out of the house, not in. That kind of run time wears on the compressor and the outdoor fan motor before the cold months ever test the reversing valve.
Storms are the other side of it. Pearl River County has logged 34 damaging wind events over the past ten years, and in 2024 nearly a third of Mississippi households lost power for at least 24 hours. A heat pump that loses power mid-cycle and comes back on hard, or takes a hit from wind-blown debris outside, often shows it in a tripped breaker or a unit that runs but never gets the house to temperature.

Mississippi requires HVAC contractors to hold a state license.
The Board of Contractors issues that license to the contractor, not to a single job. It's the same license whether the work is a heat pump repair, a furnace swap, or anything else the contractor takes on.
Repairing a heat pump means opening the refrigerant side of the system, and that requires EPA Section 608 certification everywhere in the country, not just Mississippi. So this job carries two things behind it, the state license held by the contractor and the federal certification held by whoever handles the refrigerant.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump blows air that feels cool even when it's working right, because the air coming out is warmer than the room but still well below your skin temperature. If the air is actually cold, not just lukewarm, check that the thermostat is set to heat and not fan only. A frozen outdoor coil or a system stuck in defrost can also send cold air through the vents, and that points to a problem a contractor needs to look at.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit during a cold snap is normal, and the system should clear it on its own through a defrost cycle. Thick ice that builds up and stays means something is stopping that cycle from working, often low refrigerant or a fan that isn't moving air across the coil. Since winter lows here average 41°F, heavy icing isn't something the cold alone explains, and it needs a licensed contractor to check the refrigerant charge and the defrost controls.
- Why is my heat pump running but not cooling?
- If the unit runs but the air isn't cold, the most common causes are a dirty filter blocking airflow, a coil that's frozen over, or refrigerant that has leaked out. Low refrigerant won't fix itself and won't go back to normal levels on its own. Diagnosing which of these it is means opening the refrigerant side of the system, which by federal law only a technician with EPA Section 608 certification can do.
