A heat pump in Cullman works all year, with no season off
Your heat pump runs every month here, cooling from May through September and heating from October through April. There is no stretch where it sits idle. Most homes in this area heat with electricity, which means the heat pump is doing the work a furnace would do elsewhere, on top of all the cooling.
On winter nights near 33°F it has to pull heat out of cold air, and on summer afternoons near 88°F it has to push heat out against the heat. Both directions load the compressor and the reversing valve, the parts that switch the system between heating and cooling. Cullman County has also seen 174 damaging wind events and 5 winter storms over the past ten years, and a power interruption like those can trip a heat pump's control board or leave it needing a reset before it runs again.

Alabama requires HVAC contractors to hold a state license.
The state board tests contractors before they get that license, and keeps a record of who holds one. It covers the contractor's standing to do this work in Alabama, not any single job. That's what's on file if something goes wrong.
A heat pump repair usually means opening the refrigerant side, and federal law requires the technician doing that to hold EPA Section 608 certification, regardless of what state they work in. The Alabama license tells you the contractor is accountable to the state board. The federal certification tells you the person handling the refrigerant is qualified to do it.

- 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 is warmer than the room but still well under body temperature. If the air is actually cold, not just cool, check that the thermostat is set to heat and not fan only. If the outdoor unit never seems to turn on, or the air stays cold for more than a few minutes, the system needs a contractor to look at it.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit during winter is normal, and the system defrosts itself on a regular cycle. If the coil is coated in thick ice, or ice keeps building up faster than it melts off, something is keeping that defrost cycle from working, like a stuck sensor or a fan that isn't running. Ice that doesn't clear on its own means the unit needs a contractor to find out why.
- Why is my heat pump running but not cooling?
- If both units are running but the air coming out isn't cold, the most common causes are low refrigerant from a leak or a coil that's dirty or frozen and can't move heat the way it should. Check the filter first, since a clogged one restricts airflow across the coil and can cause this. If the filter is clean and the air still isn't cooling, a contractor needs to check refrigerant levels and the coils.
