Ten months of work in Lee County
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 a year with barely a break, and only two months where it gets to rest.
Winter nights averaging 34°F mean the system spends a lot of hours pulling heat out of cold air, and it works hardest right when a defrost cycle kicks in to clear frost off the outdoor coil. That reversing valve and the defrost board take the wear. In summer, afternoons near 90°F push the compressor and the outdoor fan motor hard for months straight. And with 94 damaging wind events recorded here over the past ten years, the outdoor unit itself takes a beating, from debris in the coil to a cabinet knocked out of level.

Mississippi requires HVAC contractors to hold a state license.
Mississippi's Board of Contractors tests contractors before it licenses them, and it keeps a record of who holds one. The license belongs to the contractor, not to this particular job. It tells you the person or company behind the work has met the state's standard. It does not mean this repair was separately checked.
A heat pump repair usually means opening the refrigerant side of the system to check the charge or fix a leak. Federal law requires EPA Section 608 certification for that work, no matter which state the job is in. The state license says the contractor is licensed to work in Mississippi. The federal certification says whoever handles the refrigerant is trained to do it safely.

- Why is my heat pump blowing cold air?
- In heating mode, your heat pump puts out air that's warm but well below body temperature, so it can feel cool even when the system is working right. If the air feels truly cold, not just mild, check that the outdoor unit is running and isn't iced over. A dirty filter can also keep the air from warming enough, and so can a low refrigerant charge, though that last one needs a contractor to check, since opening the sealed system by law takes an EPA-certified technician.
- Why is there ice on my heat pump?
- Some frost on the outdoor coil during a cold snap is normal, and the unit should clear it on its own with a defrost cycle every so often. With winter lows here averaging 34°F from December through February, that cycle runs often through the coldest stretch of the season. Ice that keeps building instead of melting off usually means the defrost control has failed, a fan isn't moving air across the coil, or the refrigerant charge is off. Any of those needs a contractor, since the coil and refrigerant side aren't something to open up yourself.
- Why is my heat pump running but not cooling?
- If the outdoor and indoor units are both running but the air coming out isn't cold, the most common cause is low refrigerant from a leak, or a coil so dirty it can't pull heat out of the air. Check the filter first, since a clogged one starves the system of airflow and can mimic this problem. With summer afternoons here reaching 90°F, a system that's lost its charge will run long stretches without ever bringing the house down to temperature. Diagnosing the refrigerant side legally requires an EPA-certified technician, so a contractor will need to check the charge and pressures.
