Ten months of work a year wears on a heat pump
Your heat pump runs from November through March to keep the house warm, then switches over and runs May through September to keep it cool. That is ten months of the year with barely a break, and it puts real hours on the compressor and the reversing valve, the part that switches the system between heating and cooling. When that valve sticks, the unit can get stuck blowing cold air in winter or warm air in summer.
Winter nights here average 35°F, cold enough that the outdoor unit has to run defrost cycles to clear frost off the coil. A defrost system that isn't working right leaves ice built up on the coil, and the unit struggles to pull heat from the air. On the other end, summer afternoons average 90°F, and the compressor works hardest right when you need it most. Mississippi sees its share of power interruptions too, and a heat pump that loses power mid-cycle can come back with a control board that needs a reset or a capacitor that didn't survive the surge.

Mississippi requires HVAC contractors to hold a state license.
The state Board of Contractors tests contractors before granting that license and keeps a record of who holds one. It covers the contractor as a whole, not each job, so the license speaks to the company's standing with the state rather than to this one repair.
A heat pump repair almost always means opening the refrigerant side, and federal law requires whoever does that to hold EPA Section 608 certification, no matter what state they work in. That certification is separate from the state license. The license means Mississippi tested and recorded the contractor. The 608 card means the person handling the refrigerant is certified to do that specific part of the work.

- Why is my heat pump blowing cold air?
- In heating mode, air from a heat pump comes out warm but not hot, nowhere near as hot as a furnace. That can feel cool against your skin, especially when it mixes with room air or blows past you in a draft. If the air feels truly cold, not just mild, the system may be stuck in cooling mode, low on refrigerant, or the outdoor unit may have iced over and stopped pulling in heat. A contractor can check the refrigerant charge and the reversing valve to find out which it is.
- Why is there ice on my heat pump?
- A thin layer of frost on the outdoor unit during a cold snap is normal. Your heat pump runs a defrost cycle on its own to melt it off, then goes back to heating. Heavy ice that builds up and doesn't clear on its own is different. That points to a fan that's not moving air across the coil, a low refrigerant charge, or a defrost control that's failed. A contractor can tell which one it is by checking the fan, the charge, and the control board.
- Why is my heat pump running but not cooling?
- If the outdoor unit and indoor fan are both running but the air isn't cooling, the system likely isn't moving heat out of the house the way it should. The most common cause is low refrigerant, often from a leak, which means the coil can't absorb heat from the air passing over it. A dirty outdoor coil that can't release heat, or a failing compressor, can cause the same thing. Only a technician with EPA 608 certification can open the refrigerant side to check the charge and find a leak, so that's the next step.
