Ten months of work a year on a Meridian heat pump
Your heat pump runs almost year round here, heat from November through March, cooling from May through September. That only leaves a couple of months where it sits idle. Winter nights averaging 37°F mean it runs the defrost cycle often, and summer afternoons near 90°F push it hard on the cooling side. Two months of real rest a year wears differently on a system than one built for a short season.
Most homes in this area heat with electricity, so when the heat pump falters, there is no backup furnace picking up the slack. Meridian has seen 126 damaging wind events and 4 winter storms over the past ten years, and close to a third of Mississippi households lost power for at least a day in 2024. A heat pump that loses power and doesn't restart on its own leaves a house with no heat and no cooling until someone resets it.

Mississippi requires HVAC contractors to hold a state license.
The state issues one license to the contractor's business, not a separate one for each job it takes on. That license is on file with the State Board of Contractors, so a contractor working on your heat pump in Lauderdale County is tested and recorded by the state before they ever pick up a wrench.
A heat pump repair almost always means opening the refrigerant side of the system, and federal law requires anyone who does that to hold EPA Section 608 certification, no matter what state they work in. In Mississippi, that federal certification sits alongside the state license, so the contractor is accountable both for the license they hold and for the refrigerant work itself.

- Why is my heat pump blowing cold air?
- In winter this usually means the heat pump is stuck in defrost or the reversing valve isn't switching back to heat mode. The air from a heat pump in heating mode is naturally cooler than furnace air, often in the 90s, so what feels cold to the hand isn't always a problem. If the air feels truly cold, close to room temperature or below, and stays that way, a stuck reversing valve or a low refrigerant charge is the likely cause. A technician who is EPA 608 certified will need to check the charge, since that means opening the refrigerant side of the system.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit during a cold snap is normal, especially on winter nights here that average 37°F. Your heat pump should run a defrost cycle on its own to melt it off. Ice that builds up thick, covers the coil, or never clears means the defrost cycle isn't kicking in, or airflow across the coil is blocked. A dirty coil, a failed fan motor, or a bad defrost control board are the common causes, and each needs a contractor to sort out which one it is.
- Why is my heat pump running but not cooling?
- If the unit runs but the air coming out isn't cold, the most common cause is a dirty air filter or blocked coil cutting off airflow. Low refrigerant from a leak is another common cause, and that's a repair only a technician with EPA 608 certification can legally handle, since it means opening the refrigerant side of the system. On a 90°F afternoon here, a system that's low on refrigerant or short on airflow will struggle to keep up, so it's worth having it checked before the next hot stretch.
