Your heat pump works all year here, with no real break
Denham Springs asks for cooling from April through October and heat from November through March. That is every month of the year with the system running one way or the other, and it means the parts inside never really get a rest.
Summer afternoons averaging 91°F push the compressor hard for seven months straight. Then winter nights averaging 42°F ask the same unit to reverse and pull heat from the outside air, working the reversing valve every time it switches. Add in wind. Livingston Parish has seen 59 damaging wind events over the past ten years, and with most homes here heating on electricity, a power interruption means the heat pump stops cold until it comes back. You may notice the system struggling to keep up on the hottest afternoons, or blowing air that is not quite warm enough on a cold night.

Louisiana requires HVAC contractors to hold a state license.
The Louisiana State Licensing Board for Contractors is the one that issues the license, and it tests the contractor and keeps a record of them before any work happens. That license belongs to the contractor, not the job, so it does not get re-issued each time someone calls one out to a house in Livingston Parish.
For a heat pump repair, the state license is what stands behind the contractor doing the work. If the repair involves opening the refrigerant side of the system, which most heat pump repairs do, the technician also has to hold EPA Section 608 certification, a federal requirement that applies no matter what state you're in. That certification is separate from the state license, and it exists because refrigerant work is regulated on its own terms across the whole country.

- Why is my heat pump blowing cold air?
- A heat pump moving cold air in the winter usually means it is stuck in defrost mode or blowing before the heat has caught up. When outdoor temperatures drop toward freezing, the system reverses itself for a few minutes to melt frost off the outdoor coil, and the air at your vents will feel cool during that cycle. If the air stays cold well after that, the problem could be low refrigerant, a failing reversing valve, or the thermostat calling for the wrong mode. A contractor licensed through the Louisiana State Licensing Board for Contractors can check the refrigerant charge and the reversing valve, and anyone opening the refrigerant lines has to hold EPA Section 608 certification.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit in winter is normal, and the system should clear it on its own through a defrost cycle every so often. Ice that builds up thick or does not melt off points to a real problem, often restricted airflow from a dirty coil or filter, low refrigerant, or a failing defrost control. With winter nights here averaging 42°F, the outdoor coil runs cold enough that a struggling defrost cycle can let ice build up fast. If the ice keeps coming back, have a licensed contractor look at the defrost board and refrigerant level rather than chipping the ice off yourself.
- Why is my heat pump running but not cooling?
- If the unit is running but the air is not cold, the most common causes are a dirty filter blocking airflow, a low refrigerant charge, or a frozen outdoor or indoor coil. Summer afternoons here average 91°F, so a system that is even a little undercharged or restricted will struggle to keep up on the hottest days. Check the filter first since that is the one thing you can rule out yourself. If the filter is clean and the air still is not cooling, a licensed contractor will need to check refrigerant levels and the coils, and anyone working on the refrigerant side has to carry EPA Section 608 certification.
