Eleven months of work a year in Jackson
Your heat pump runs almost year round here, heat from November to March and cooling from May through October. There is barely a month it gets to sit idle. That kind of duty cycle wears on the compressor and the outdoor fan motor faster than a system that gets a real break each year.
Summer afternoons averaging 91°F push the unit hard on the cooling side, and winter nights averaging 38°F mean the system is working the reverse valve and defrost cycle for months straight. Add in the wind events this area sees, 270 of them over the past ten years, and outdoor coils and electrical connections take a beating too. More than half of homes here heat with electricity, so when the heat pump falters, there is no backup furnace quietly taking over. You feel it right away, in a room that will not warm up or an outdoor unit that runs constantly without catching up.

Mississippi requires HVAC contractors to hold a state license.
The state board tests contractors before it licenses them, and the license stays tied to that person or company, not to any single visit. It is a record you can trace back to someone the state has already screened, and that record does not reset with each new job.
Heat pump repair often means opening the refrigerant side, and federal law requires anyone who does that, in any state, to hold EPA Section 608 certification. That is separate from the state license and covers a different risk, the refrigerant itself rather than the contractor's standing. In Mississippi, a licensed contractor working on a heat pump should carry both.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump puts out air that feels cool next to your skin even when it is working right, because the air coming out is warmer than the room but still cooler than your body. If the air is actually cold, or the system is running nonstop and the house isn't warming up, that points to something else, like low refrigerant, a stuck reversing valve, or a frozen outdoor coil. A contractor can check the refrigerant charge and the reversing valve to find out which one it is.
- 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 regular cycle to clear it. If you're seeing heavy ice that builds up faster than it melts off, or ice that's still there hours after a defrost cycle should have run, something is keeping the coil too cold or blocking airflow across it. That can mean a dirty coil, a failing defrost control, low refrigerant, or a fan that isn't moving air the way it should. Cold nights here make this worse, since winter lows average 38°F, so the coil is already working against outdoor air that's near freezing or below.
- Why is my heat pump running but not cooling?
- If the outdoor unit is running and the indoor air isn't getting cold, start with the filter and the vents, since a blocked filter or closed vents can choke off airflow enough that the house never cools down. If those are clear, it's more likely low refrigerant, a failing compressor, or a reversing valve stuck in heating mode. With summer afternoons here averaging 91°F, a system that's low on refrigerant or losing capacity will fall behind fast and struggle to keep up. A contractor can check refrigerant charge and pressures to find out which one it is.
