Ten months of work, most of it in the cold
Jasper asks a heat pump to run nearly year round, heat from November through March and cooling from May through September. On winter nights averaging 34°F, a heat pump works harder than most people expect, since it has to pull heat out of cold air instead of just burning fuel. That strain shows up in the compressor and the reversing valve first, the parts that carry the load every time the system switches modes.
Walker County has seen 65 damaging wind events over the past ten years, and storms here knock out power often enough that 18% of Alabama households lost it for a full day or more in 2024. A heat pump that loses power mid-cycle can trip its own safety switches, and if it does not come back on when the lights do, that switch is usually why.

Alabama requires HVAC contractors to hold a state license.
The Alabama Board of Heating, Air Conditioning & Refrigeration Contractors tests and licenses HVAC contractors before they can take on work like this. The license belongs to the contractor, not to the specific job, so it stands behind everything they do in your home, not just this one repair.
A heat pump repair usually means opening the refrigerant side of the system, and federal law requires anyone who does that, in every state, to hold EPA Section 608 certification. In Alabama that certification sits alongside the state license rather than replacing it. Between the two, the person working on your heat pump has been tested on the trade and on handling refrigerant.

- Why is my heat pump blowing cold air?
- In winter, this usually means the system is stuck in defrost mode or backup heat isn't kicking in when it should. A heat pump moves heat from outside air, so on a 34°F night it naturally puts out air that feels cooler than a furnace would, even when it's working right. If the air feels cold rather than just cool, or the outdoor unit is running but nothing warm comes through the vents, a contractor needs to check the reversing valve and the backup heat strips.
- Why is there ice on my heat pump?
- A thin layer of frost on the outdoor unit during cold weather is normal, and the system should melt it off on its own through periodic defrost cycles. Heavy ice that builds up and stays means something is stopping that cycle, often low refrigerant, a failing defrost control, or a fan motor that isn't moving air across the coil. Left alone, the ice keeps the coil from absorbing heat and can damage the compressor, so it needs a contractor's attention rather than waiting for it to melt.
- Why is my heat pump running but not cooling?
- If the outdoor unit and indoor blower are both running but the air isn't cold, the most common cause is low refrigerant from a leak, or a coil that's iced over or coated in dirt. On a 90°F afternoon here, a system low on refrigerant will run long and still lose the fight against the heat. A dirty air filter can also choke off airflow enough to cause this, so check that first before calling anyone out.
