Your heat pump works almost all year here
In Thibodaux your heat pump runs from April through October to cool the house, then switches over come November to heat it through February. That's 11 months of the year it's doing something. Only a short stretch in between gives it any rest.
That switchover matters. The reversing valve is what flips the system between heating and cooling, and with so little downtime it doesn't get much of a break either. When it sticks, you'll notice the system blowing air that's the wrong temperature for the setting, or the outdoor unit running when it should be idle. With most homes here heating on electricity, a heat pump that stalls out leaves you without a backup plan. And with wind events hitting the area 16 times over the past ten years, a heat pump that loses power might not restart on its own when it comes back.

Louisiana requires HVAC contractors to hold a state license.
The license is issued by the Louisiana State Licensing Board for Contractors. It covers the contractor as a whole, not this specific repair at your house.
A heat pump repair almost always means getting into the refrigerant side of the system. That work falls under a separate federal rule that applies in every state. Whoever opens the refrigerant side has to hold EPA Section 608 certification. On this job, the state license covers the contractor, and the federal certification covers whoever handles the refrigerant itself.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump puts out air that feels cool compared to your skin even when it is working right, since the air coming out is closer to body temperature than a furnace's hot air would be. If the air is actually cold, not just cool, check that the thermostat is set to heat and not fan only. If it is set correctly and still blowing cold, the system may have lost refrigerant or the reversing valve that switches it between heating and cooling could be stuck. That valve needs a licensed contractor to diagnose, since finding the cause means opening the refrigerant side of the system.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit during winter is normal. Your heat pump runs a defrost cycle on its own to melt it off, then goes back to heating. If ice is building up faster than it melts, or you see a thick coating that stays for hours, something is stopping that defrost cycle from working. That can be a low refrigerant charge, a failed defrost sensor or control board, or an outdoor fan that has stopped turning. Any of those needs a contractor to open the unit and check, since guessing at the cause from outside will not tell you which one it is.
- Why is my heat pump running but not cooling?
- First check the air filter and the outdoor unit for anything blocking airflow, since a clogged filter or a coil covered in leaves and grass clippings will stop a heat pump from cooling even though it keeps running. If both are clear, the system is likely low on refrigerant, which usually means a leak somewhere in the line. A licensed contractor holding EPA Section 608 certification is required by federal law to open the refrigerant side and find it. On a 90°F afternoon here, a system that is not actually cooling will fall behind fast, so this is worth having looked at sooner rather than later.
