Five months of Greenville heat wears on a system
Your air conditioner runs from May through September here, with afternoons averaging 91°F. That is five straight months of long runs, not short bursts. The compressor and the fan motor carry that load every one of those days, and a system that seemed fine in May can start struggling to keep up as the summer goes on.
Washington County has also logged 84 damaging wind events and 21 hail events over the past ten years, with hail up to 2.75 inches. The outdoor unit sits through all of it. Wind can bend the thin fins on the condenser coil, and hail that size can dent them or crack a fan blade. Once those fins are bent, the coil cannot shed heat the way it should, so the system runs longer to cool the same house.

A new air conditioner would cut about $70 a year off cooling for a typical Washington County home.
Estimates for a typical Washington County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Mississippi fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when a part like a capacitor or contactor has failed.
Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.
Mississippi requires HVAC contractors to hold a state license.
The Mississippi State Board of Contractors licenses HVAC contractors statewide. That license belongs to the contractor, not to any single job, so the same license that covers a new installation covers a repair call to your air conditioner.
For this job, that license is what stands behind the work. Because a repair on your air conditioner likely means opening the refrigerant side of the system, the technician also needs EPA Section 608 certification, which is a federal requirement in every state and applies on top of the Mississippi license.

- Why is my AC not blowing cold air?
- The most common reason is a dirty air filter choking off airflow across the coil. When that happens the coil can ice up, and once it's iced over the air coming through the vents turns warm. Low refrigerant from a leak will cause the same thing, but that's not something to check yourself, since it means opening the refrigerant side of the system, which by federal law only an EPA-certified technician can do. If the filter looks clean and you're still getting warm air, especially on a 91°F afternoon when the system is working hardest, it's worth having someone look at the refrigerant charge and the coil itself.
- Why is my AC leaking water?
- Most of the time this is a clogged condensate drain line. Your AC pulls moisture out of the air as it runs, and that water is supposed to drain out through a small line. Algae and dirt build up inside that line over time and eventually block it, so the water backs up and finds its way out somewhere in your house instead. A frozen coil that's thawing out can cause the same kind of leak, so it helps to mention to whoever comes out whether the system had been blowing warm air before the leak started.
- Why won't my AC turn on?
- Start with the thermostat. Check that it has power, that the setting is actually below the room temperature, and that the batteries aren't dead if it uses them. If the thermostat looks fine, check your breaker panel, since a tripped breaker is a common reason the outdoor unit won't start. Greenville's storm history includes hail up to 2.75 inches and dozens of damaging wind events over the past ten years, so if either hit your neighborhood recently, it's worth having a contractor check the outdoor unit before assuming it's just a simple reset.
