Your heat pump works almost all year here
In Gulfport, your heat pump cools through summer afternoons that average 90°F and heats on winter nights that average 42°F. Only one month goes by without asking it for either. That much runtime, and that much switching between heating and cooling, wears on the reversing valve over time. A valve that sticks shows up as air that is not warm enough in winter or not cool enough in summer, or a system that runs long without catching up.
The coast adds power loss to that. Harrison County has seen 53 damaging wind events over the past ten years, and statewide, 30% of households went at least 24 hours without power in 2024. A heat pump that cuts out mid-cycle and restarts once power returns is putting extra stress on its electrical parts each time. If your outdoor unit will not start back up after an outage, that is often where to look.

Mississippi requires HVAC contractors to hold a state license.
Mississippi tests contractors before they can hold this license, and the Board of Contractors keeps a record of who holds one. The license belongs to the contractor, not to any single job, so it does not get reissued for your repair. It is still the state's word that this contractor was checked before being allowed to work.
A heat pump repair often means opening the refrigerant lines. Federal law requires anyone who does that, in Mississippi or any other state, to hold EPA Section 608 certification. That certification is separate from the state license. It confirms the technician was trained to handle refrigerant without releasing it into the air.

- Why is my heat pump blowing cold air?
- In heat mode, air from the vents feels cool even when the system is working right, since it's warmer than the room but still well below body temperature. If the air is actually cold and the house isn't warming up, check that the thermostat is set to heat and not fan only. It could also mean the system has lost refrigerant or the reversing valve isn't switching over, and that needs a licensed contractor to check.
- Why is there ice on my heat pump?
- A heat pump forms frost on the outdoor coil during normal winter defrost cycles, and it should clear on its own every hour or so. If ice is building up and staying, the unit likely has low refrigerant, a failing defrost control, or an outdoor fan that isn't turning. With winter nights here averaging 42°F, the outdoor coil is working hard most nights, so ice that doesn't melt off is worth having looked at soon.
- Why is my heat pump running but not cooling?
- If the unit runs but the air isn't cold, start with the filter. A clogged one starves the coil of airflow and can freeze it over, which stops cooling even though the system keeps running. If the filter is clean, the cause is more likely low refrigerant or a failing compressor, and only a technician with EPA 608 certification can legally open the refrigerant side to check.
