Morgan City runs its heat pump almost year round
There is no real off season here. Cooling runs April through October, seven months, and the switch to heat only lasts from November through March before the unit is back to cooling again. That means the compressor and reversing valve rarely get a long rest, and the wear that would spread over a full year somewhere else happens here in twelve months of steady use.
Summer afternoons averaging 90°F push the system hard on the cooling side, while winter lows near 47°F keep it working on the heat side more than people expect from a place this warm. Add in the wind. St. Mary Parish has seen 16 damaging wind events over the last ten years, and with 64.6% of homes here heating with electricity, a heat pump that trips offline during a storm is the only thing standing between a family and no heat at all. When the power comes back on, most units restart on their own, but if a storm has jarred a wire loose or damaged the outdoor unit, it will not.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors is the body that issues this license, and it tests the contractor before putting the name on record. That license belongs to the contractor, not to any single job, so the same credential that covers a new installation across the parish also covers a repair call on 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. Whoever touches that refrigerant line has to hold EPA Section 608 certification, on top of whatever the state requires. In St. Mary Parish, that means the contractor working on your heat pump answers to both the state license and this federal certification.

- Why is my heat pump blowing cold air?
- A heat pump blowing cold air in winter usually means it's stuck in defrost mode or the reversing valve isn't switching over the way it should. The reversing valve tells the system whether to act as an air conditioner or a heater, and when it sticks, the unit keeps blowing air that never gets warm. It can also mean the system has lost refrigerant, since a heat pump that's low on charge can't move enough heat to warm the air passing over the coil. A contractor will need to check the reversing valve and refrigerant charge to find out which one it is.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit during winter is normal, and the system should clear it on its own through a defrost cycle. If ice is building up faster than it melts, or covering the coil heavily, airflow is likely blocked, either from a dirty coil, a failed fan motor, or low refrigerant. Winter nights here average 47°F, cold enough that a heat pump with a real problem can ice over repeatedly instead of defrosting clean. If the ice keeps coming back after the unit runs its defrost cycle, the defrost control board or a sensor may be the reason.
- Why is my heat pump running but not cooling?
- If the heat pump runs but the air coming out isn't cool, the most common cause is low refrigerant from a leak somewhere in the system. A dirty outdoor coil can cause the same problem, since it stops the unit from releasing heat properly during cooling mode. With summer afternoons here reaching 90°F, a system that's low on refrigerant or fighting a blocked coil will struggle to keep up and may run constantly without cooling the house. A contractor will need to check the refrigerant charge and inspect the coil, since anyone working on the refrigerant side is required to hold EPA Section 608 certification.
